Abstract
PURPOSE To assess the efficacy and safety of intra-arterial injection of imipenem/cilastatin sodium (IPM/CS) via a needle placed into the radial artery or ulnar artery (RA/UA) for distal interphalangeal and proximal interphalangeal joint osteoarthritis (DIP/PIP-OA). MATERIALS AND METHODS This is a retrospective single-arm cohort study. Ninety-two patients [92% women, mean (SD) age 55(8.3) years] with a primary DIP/PIP-OA meet the American College of Rheumatology criteria for hand osteoarthritis with pain ≥ 4 on the 0-10 numeric rating scale (NRS) were enrolled. All procedures were performed by injecting IPM/CS through a 24-gauge needle percutaneously inserted into the RA/UA. Two procedures were planned; the second procedure was scheduled 1-2 months after the first. NRS, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, Patient Global Impression of Change (PGIC) scale, and procedure-related adverse events were evaluated. RESULTS Technical success, defined as injection of IPM/CS into the RA/UA, was achieved in all patients. Clinical success, defined as a reduction of 2 points or more in the NRS at 12 months, was 77% (95% confidence interval 68-85%). The NRS improved from the baseline to 3, 6, and 12 months (7.8 ± 1.6 vs. 3.8 ± 2.6, 3.9 ± 2.7, and 4.0 ± 2.8, respectively, all p < 0.001). The QuickDASH score improved from the baseline to 12 months (27 ± 15 vs. 19 ± 17, p < 0.001) respectively. No major adverse events were observed. CONCLUSIONS Intra-arterial injection of IPM/CS is a feasible treatment option for DIP/PIP-OA.

Abstract
BACKGROUND In recent years, transcatheter arterial embolization (TAE) using imipenem/cilastatin (IPM/CS) has attracted attention as a treatment for relieving osteoarthritis (OA) pain. However, IPM/CS is not approved by Japanese medical insurance for use as an embolic material. Therefore, it is necessary to develop new embolic materials for TAE to relieve OA pain. The purpose of this study was to develop a swine model of knee arthritis and embolize abnormal neovessels (ANs) using two different embolic materials. We compared the embolic effects and tissue damage in knees. METHODS Knee arthritis was induced by intra-articular injection of papain into 12 knees in six female swine. The swine were divided into two groups of three swine each (six knees per group) for embolization of ANs in the knees with either IPM/CS or soluble gelatin sponge particles (SGSs). Three days after embolization, we compared the embolic effects using angiography and the tissue damage histopathologically. RESULTS ANs were observed in all 12 knees at 42 days after papain injection. The ANs disappeared and the patent arteries were recanalized 3 days after TAE in all 12 knees. Histopathological evaluation revealed synovitis changes, such as synovial thickening and inflammatory cell infiltration, in all 12 knees. There was no evidence of skin or muscle necrosis in either group. The appearance of ANs, recanalization of the parent arteries, and histopathological outcomes were not significantly different between the two groups. CONCLUSION SGSs were as safe as IPM/CS for TAE of ANs in this swine model of knee arthritis.

Abstract
PURPOSE To evaluate the safety and 2-year follow-up clinical outcomes of transcatheter arterial embolization (TAE) using imipenem/cilastatin sodium for chronic low back pain resistant to conservative treatment. MATERIALS AND METHODS A retrospective review identified 14 patients who underwent TAE for chronic low back pain between October 2017 and August 2018. Patients with low back pain related to the facet or sacroiliac joint, lasting ≥ 6 months, refractory to ≥ 3 months of conservative treatment were eligible for TAE. Each patient received embolization of feeding arteries of painful regions. The changes in brief pain inventory (BPI) scores, adverse events, and the Oswestry Disability Index (ODI) were evaluated at baseline and 1, 3, and 24 months after TAE. Clinical success was defined as BPI maximum pain intensity decrease of ≥ 2 and ODI decrease of ≥ 10 points from baseline. RESULTS Follow-up data were available in 13 and 11 patients, at 3 and 24 months after embolization, respectively. Intention-to-treat clinical success was obtained in 11/14 (79%) of patients at 3 months and 8/14 (57%) of patients at 24 months after TAE. Mean BPI maximum pain intensity and ODI scores decreased significantly from baseline to 1, 3, and 24 months after treatment (7.6 vs.. 4.3, 3.4, and 4.1; 40.8 vs 21.5, 20.0, and 23.8, respectively; all P < 0.01). No major adverse events were associated with the procedures. CONCLUSION TAE is one possible treatment option for patients with chronic low back pain refractory to conservative treatment.

Abstract
This case report concerns a 51-year-old woman with a 6-month history of severe right heel pain diagnosed as plantar fasciitis (PF) treated with intra-arterial infusion of imipenem/cilastatin (IPM/CS) through a 24G indwelling needle directly inserted into the posterior tibial artery (PTA). Angiography of the indwelling needle immediately before the infusion of IPM/CS demonstrated an increased number of abnormal vessels at the calcaneal attachment of the plantar fascia. Two procedures were planned: The first procedure was performed, and the second was performed 1 month after the first. A week after the first treatment, her pain gradually decreased. Three months after the first treatment, she no longer had difficulties with activities of daily living. Intra-arterial infusion of IPM/CS directly through an indwelling needle into the PTA represents a minimally invasive embolic treatment option for PF.

Abstract
BACKGROUND This study evaluated the mechanism of decline in coronary pressure from the proximal to the distal part of the coronary arteries in the left anterior descending (LAD) versus the right coronary artery (RCA) from the insight of coronary hemodynamics using wave intensity analysis (WIA). METHODS Twelve patients with angiographically normal LAD and RCA were prospectively enrolled. Distal coronary pressure, mean aortic pressure, and average peak velocity were measured at 4 different positions: 9, 6, 3, and 0 cm distal from each coronary ostium. RESULTS The distal-to-proximal coronary pressure ratio during maximum hyperemia gradually decreased in proportion to the distance from the ostium (0.92±0.03 and 0.98±0.03 at 9 cm distal to the LAD and RCA ostium). WIA showed the dominant forward-traveling compression wave gradually decreased and the backward-traveling suction wave gradually decreased in proportion to the decrease in coronary pressure through the length of the non-diseased LAD but not the RCA. CONCLUSIONS The pushing wave and suction wave intensities on WIA were diminished in proportion to the distance from the ostium of the LAD despite the wave intensity not changing across the length of the RCA, which may lead to gradual intracoronary pressure drop in the angiographically normal LAD.

Abstract
PURPOSE To evaluate the safety and efficacy of transcatheter arterial microembolization for patients with trapezius myalgia. MATERIALS AND METHODS We retrospectively evaluated the prospectively collected data of patients with trapezius myalgia for > 6 months who were refractory to conservative treatment and were treated by transcatheter arterial microembolization between October 2017 and January 2019. Transcatheter arterial microembolization was performed using imipenem/cilastatin on the vessels of the transverse cervical artery, suprascapular artery, and circumflex scapular artery according to the region of pain. RESULTS Forty-two patients were treated by transcatheter arterial microembolization and followed up for 6 months. No major adverse events occurred related to the procedures. The brief pain inventory worst pain scores significantly improved at 1, 2, 3, and 6 months after transcatheter arterial microembolization (8.6 ± 1.3 (before procedure) vs. 5.1 ± 2.9, 4.4 ± 2.9, 4.1 ± 2.8, and 3.9 ± 2.9, respectively, P < 0.001). The brief pain inventory pain interference scores, including general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life, also significantly decreased at 1, 2, 3, and 6 months after transcatheter arterial microembolization compared to those at baseline (all P < 0.01). The clinical success rate at 6 months after transcatheter arterial microembolization was 71.4% (95% confidence interval, 55.4-84.3%). CONCLUSION Transcatheter arterial microembolization is a safe and effective treatment for persistent trapezius myalgia. Further evaluation with a control group is needed to confirm the effects of transcatheter arterial microembolization. LEVEL OF EVIDENCE Level 4, Case Series.

Abstract
OBJECTIVE Adjuvant chemotherapy is standard of care for patients with completely resected stage IB, II and IIIA NSCLC. However, optimum chemotherapy regimen has not been determined. TORG0503 was undertaken to select a preferred platinum-based 3rd generation regimen in this clinical setting. MATERIALS AND METHODS Patients with completely resected stage IB, IIA, IIB or stage IIIA NSCLC were stratified by stage (IB/IIA vs. IIB/IIIA) and institutions, and randomized to receive 3 cycles of docetaxel (60 mg/m2) plus cisplatin (80 mg/m2) (arm A) or paclitaxel (200 mg/m2) plus carboplatin (AUC 6) (arm B) on day 1, every 3 weeks. The primary endpoint of the study was 2-year relapse free survival, and the key secondary endpoints included overall survival, feasibility and toxicity. RESULTS 111 patients were randomized, 58 patients to arm A and 53 to arm B. Patient demographics were balanced between the two arms. 93 % (54/58) of patients on the arm A and 92 % (49/53) patients on the arm B completed the planned 3 cycles of chemotherapy. There was no treatment-related death in both arms. The 2 and 5 year relapse free survival was 74.5 % (95 %CI: 68.6-80.4) and 61.6 % in the arm A, and 72.0 % (95 %CI: 65.7-78.3) and 46.0 % in the arm B. The overall 2, 5-year survival was 89.7 %, 73.9 % in the arm A and 86.9 %, 67.5 % in the arm B. CONCLUSION Both docetaxel plus cisplatin and paclitaxel plus carboplatin are safe and feasible regimens as adjuvant chemotherapy. We choose docetaxel plus cisplatin as the control regimen for the next clinical trial.

Abstract
Skeletal-related events (SREs) may occur at the time of first diagnosis in 20-30% of lung cancer patients with bone metastases. Several clinical trials have shown that zoledronic acid (ZA) is effective for decreasing SREs. The main objective of the present study was to discuss clinical data of ZA and compare the frequency of SREs with previous reports. All patients with non-small-cell lung cancer (NSCLC) with metastatic bone disease who were administered ZA at least twice between January 2008 and December 2009 were eligible for inclusion in the study. In total, 198 consecutive patients were identified. The median duration of ZA administration was 106 days [95% confidence interval (CI), 92-133 days], and the median number of ZA administrations was 4 (range, 2-41). The median time to first SRE in patients who experienced SRE following ZA treatment was 202 days (95% CI, 156-264 days). Among the 78 patients who had already experienced SRE prior to ZA treatment, 35 (45%) experienced SRE subsequently after starting ZA treatment. On the other hand, among the 120 patients without a history of SRE before starting ZA treatment, 42 (35%) experienced SRE after the start of ZA administration (P=0.16). No osteonecrosis of the jaw (ONJ) was reported in any of the patients. The present study revealed that ZA had a certain level of efficacy regardless of the presence or absence of prior SREs. However, the duration of ZA therapy was short in this study; further accumulation of data on the long-term prognosis and incidence rates of ONJ and other late complications of ZA therapy seems to be particularly important.

Abstract
AIMS Drug-eluting stents (DES) have evolved to using bioresorbable polymers as a method of drug delivery. The impact of bioresorbable polymer on long-term neointimal formation, inflammation, and healing has not been fully characterised. This study aimed to evaluate the biological effect of polymer resorption on vascular healing and inflammation. METHODS AND RESULTS A comparative DES study was performed in the familial hypercholesterolaemic swine model of coronary stenosis. Permanent polymer DES (zotarolimus-eluting [ZES] or everolimus-eluting [EES]) were compared to bioresorbable polymer everolimus-eluting stents (BP-EES) and BMS. Post implantation in 29 swine, stents were explanted and analysed up to 180 days. Area stenosis was reduced in all DES compared to BMS at 30 days. At 180 days, BP-EES had significantly lower area stenosis than EES or ZES. Severe inflammatory activity persisted in permanent polymer DES at 180 days compared to BP-EES or BMS. Qualitative para-strut inflammation areas (graded as none to severe) were elevated but similar in all groups at 30 days, peaked at 90 days in DES compared to BMS (p<0.05) and, at 180 days, were similar between BMS and BP-EES but were significantly greater in DES. CONCLUSIONS BP-EES resulted in a lower net long-term reduction in neointimal formation and inflammation compared to permanent polymer DES in an animal model. Further study of the long-term neointima formation deserves study in human clinical trials.

Abstract
Phantom limb pain is a frequent consequence of the amputation; currently available treatments are far from satisfactory. The present report describes a case in which transcatheter arterial microembolization had a remarkable curative effect on phantom limb pain persisting for 17 years. The patient began feeling phantom limb sensations and brief intermittent pain following lower limb amputation above the knee in 2001. The frequency, intensity, and duration of the pain increased over time, and it was resistant to conservative treatments. Following transcatheter arterial microembolization in 2018, patient immediately experienced marked improvement. The pain has been infrequent, much less intense, and did not interfere with daily life 6 months posttreatment. Transcatheter arterial microembolization could be an alternative treatment option for phantom limb pain. LEVEL OF EVIDENCE: IV, Case Report.

Abstract
Oral surgery can be difficult in patients with chorea-like dyskinesia, which is common in those on long-term levodopa medication for Parkinson's disease, and we know of no conclusive evidence to indicate whether conscious sedation with midazolam is effective in such cases. We report a patient in whom levodopa-induced chorea-like dyskinesia disappeared when midazolam was given intravenously for conscious sedation.

Abstract
Aims This study evaluated whether optical frequency domain imaging (OFDI) could identify various coronary calcifications and accurately measure calcification thickness in comparison with histopathology. Methods and results A total of 902 pathological cross-sections from 44 coronary artery specimens of human cadavers were examined to compare OFDI and histological images. Histological coronary calcification was classified into four different types: (i) superficial dense calcified plates, (ii) deep intimal calcification, (iii) scattered microcalcification, and (iv) calcified nodule. The thickness of calcification was measured when both the leading and trailing edges of calcification were visible on OFDI. Of the 902 histological cross-sections, 158 (18%) had calcification: 105 (66%) were classified as superficial dense calcified plates, 20 (13%) as deep intimal calcifications, 30 (19%) as scattered microcalcifications, and 3 (2%) as calcified nodules. Superficial dense calcified plates appeared as well-delineated heterogeneous signal-poor regions with sharp borders on OFDI. Deep intimal calcifications could not be identified on OFDI. Scattered microcalcification appeared as homogeneous low intensity areas with indiscriminant borders. Calcified nodule, a high-backscattering protruding mass with an irregular surface, also appeared as a low intensity area with a diffuse border. The ROC analysis identified calcium thicknesses <893 µm as cut points for the prediction of measurable calcification (72% sensitivity and 91% specificity, area under the curve = 0.893, P < 0.001). Conclusion Our study demonstrated the potential capability of OFDI to characterize various types of coronary calcifications, which may contribute to the understanding of the pathogenesis of coronary atherosclerosis.

Abstract
In the presence of 5 mol% Pd(OAc)2, 1 equiv. of norbornene, and K2CO3, the reaction of 4-iodo-2-quinolones with tertiary o-bromobenzylic alcohols produced the desired benzopyran-fused 2-quinolones in moderate to high yields.

A Catellani-type mechanism involving vinylic C–H cleavage is proposed based on the results of control experiments and density functional theory calculations.

Abstract
BACKGROUND Clinically available bioresorbable scaffolds (BRS) rely on polymer crystallinity to achieve mechanical strength resulting in limited overexpansion capabilities and structural integrity when exposed to high-loading conditions. We aimed to evaluate the biomechanical behavior and vascular healing profile of a novel, sirolimus-eluting, high-molecular-weight, amorphous poly-l-lactic acid-based BRS (Amaranth BRS). METHODS AND RESULTS In vitro biomechanical testing was performed under static and cyclic conditions. A total of 99 devices (65 Amaranth BRS versus 34 Absorb bioresorbable vascular scaffold [BVS]) were implanted in 99 coronary arteries of 37 swine for pharmacokinetics and healing evaluation at various time points. In the Absorb BVS, the number of fractures per scaffold seen on light microscopy was 6.0 (5.0-10.5) when overexpanded 1.0 mm above nominal values (≈34%). No fractures were observed in the Amaranth BRS group at 1.3 mm above nominal values (≈48% overexpansion). The number of fractures was higher in the Absorb BVS on accelerated cycle testing over time (at 24K cycles=5.0 [5.0-9.0] Absorb BVS versus 0.0 [0.0-0.5] Amaranth BRS). Approximately 90% of sirolimus was found to be eluted by 90 days. Optical coherence tomography analysis demonstrated lower percentages of late scaffold recoil in the Amaranth BRS at 3 months (Amaranth BRS=-10±16.1% versus Absorb BVS=10.7±13.2%; P=0.004). Histopathology analysis revealed comparable levels of vascular healing and inflammatory responses between both BRSs up to 6 months. CONCLUSIONS New-generation high-molecular-weight amorphous poly-l-lactic acid scaffolds have the potential to improve the clinical performance of BRS and provide the ideal platform for the future miniaturization of the technology.

Abstract
AIMS The Mitra-Spacer (Cardiosolutions, Bridgewater, MA, USA) is designed to treat mitral regurgitation by introducing a dynamic spacer that constantly adapts to the changing haemodynamic conditions during the cardiac cycle. We aimed to evaluate the performance and safety of this device in the chronic ovine model. METHODS AND RESULTS Eight sheep were enrolled in this study. Through a left thoracotomy, the Mitra-Spacer was inserted via the transapical approach and advanced into the left atrium (LA) under imaging guidance. Device performance and safety were evaluated up to 90 days using fluoroscopy, echocardiography and histopathology. The volume within the balloon spacer shifted during the cardiac cycle in all cases. Seven animals survived up to 90 days for terminal imaging and tissue harvest. Echocardiography showed no change in left ventricle (LV) ejection fraction from baseline to 90 days. There were no observations of changes in LV diastolic function, pulmonary vein inflow, or tricuspid valve function. Histological analysis demonstrated no significant injury to the mitral apparatus. CONCLUSIONS In the healthy ovine model, Mitra-Spacer implantation was feasible and safe. At 90 days, no evidence of structural damage to the mitral apparatus or deterioration of cardiac performance was demonstrated.

Abstract
OBJECTIVES This study aimed to investigate the influence of analysis interval size on optical frequency domain imaging (OFDI) assessment of stent therapy for lesions of the superficial femoral artery (SFA). BACKGROUND No consensus or validating data are available with respect to the methodology of intravascular imaging analysis for the peripheral arteries. METHODS OFDI was performed for 30 SFA lesions, during endovascular therapy and at the 6-month follow-up. Initially, lumen and stent borders were traced at 1-mm axial intervals. Volumes were calculated using a PC-based software, and the volume index (VI) was defined as the volume divided by the stent length. Two additional OFDI analyses were performed using 2-mm and 5-mm intervals, thereby reducing the number of cross-sectional image frames analyzed. RESULTS The mean stent length was 89.7 ± 35.2 mm. The mean difference in baseline minimum lumen area (MLA) was 0.4 mm2 between MLA values from the 1-mm and 2-mm interval analyses, and 2.2 mm2 between MLA values from the 1-mm and 5-mm interval analyses. In volumetric analysis, there were excellent correlations and good agreements for stent, lumen, and neointimal VI measurements obtained on the basis of different analysis intervals. CONCLUSIONS Using large intervals in OFDI analyses of SFA lesions resulted in few differences in measurement variability of volumetric parameters. However, planar analysis for MLA assessment can be susceptible to high variability when large intervals are applied. © 2016 Wiley Periodicals, Inc.

Abstract
Although spontaneous coronary artery dissection (SCAD) is usually diagnosed by coronary angiography, diagnosis may be missed because of various presentations and imperfections of coronary angiography. We report a case of a 41-year-old female with pregnancy-related SCAD who presented with cardiac arrest. Initial coronary angiography was normal without intimal flap. Unexpectedly, 4 days after admission, SCAD in left main trunk was revealed with recurrent myocardial infarction. Intimal flap was sealed at the time of first angiography and this is an interesting point that made us report this case. SCAD is a rare but not negligible cause of not only acute myocardial infarction but also sudden cardiac arrest even if first coronary angiography is normal. <Learning objective: In a case of a young post-partum woman with resuscitated sudden cardiac arrest who has normal coronary artery, intensive observation is needed. We should be aware that spontaneous coronary artery dissection is a rare but not negligible cause even if initial coronary angiography is normal.>.

Abstract
PURPOSE To identify intravascular ultrasound (IVUS) measurements that can predict angiographic in-stent restenosis (ISR) following nitinol stent implantation in superficial femoral artery (SFA) lesions. METHODS A retrospective review was conducted of 97 patients (mean age 72.9±8.9 years; 63 men) who underwent IVUS examination during endovascular treatment of 112 de novo SFA lesions between July 2012 and December 2014. Self-expanding bare stents were implanted in 46 lesions and paclitaxel-eluting stents in 39 lesions. Six months after stenting, follow-up angiography was conducted to assess stent patency. The primary endpoint was angiographic ISR determined by quantitative vascular angiography analysis at the 6-month follow-up. Variables associated with restenosis were sought in multivariate analysis; the results are presented as the odds ratio (OR) and 95% confidence interval (CI). RESULTS At follow-up, 27 (31.8%) angiographic ISR lesions were recorded. The lesions treated with uncoated stents were more prevalent in the ISR group compared with the no restenosis group (74.1% vs 44.8%, p=0.02). Lesion length was longer (154.4±79.5 vs 109.0±89.3 mm, p=0.03) and postprocedure minimum stent area (MSA) measured by IVUS was smaller (13.9±2.8 vs 16.3±1.6 mm(2), p<0.001) in the ISR group. Multivariate analysis revealed that bare stent use (OR 7.11, 95% CI 1.70 to 29.80, p<0.01) and longer lesion length (OR 1.08, 95% CI 1.01 to 1.16, p=0.04) were predictors of ISR, while increasing postprocedure MSA (OR 0.58, 95% CI 0.41 to 0.82, p<0.01) was associated with lower risk of ISR. Receiver operating characteristic analysis identified a MSA of 15.5 mm(2) as the optimal cutpoint below which the incidence of restenosis increased (area under the curve 0.769). CONCLUSION Postprocedure MSA can predict ISR in SFA lesions, which suggests that adequate stent enlargement during angioplasty might be required for superior patency.

Abstract
BACKGROUND Thymic carcinoma is a rare cancer with minimal evidence of a survival benefit following chemotherapy. An oral fluoropyrimidine of S-1, however, is the recommended active cytotoxic chemotherapy agent for refractory thymic carcinoma based on a case series, whereas sunitinib or everolimus are recommended as molecular-targeted agents based on Phase II trials. We retrospectively investigated the efficacy of S-1 for refractory thymic carcinoma and performed a biomarker analysis. METHODS We assessed the clinicopathological variables of 14 consecutive patients who underwent S-1 for refractory thymic carcinoma and correlated the clinical outcomes with potential biomarkers using paraffin-embedded cancer tissues of eight patients in the cohort. RESULTS A total of 178 thymic malignancies were identified, of whom 14 patients included 12 cases of squamous cell carcinoma, one lymphoepithelioma-like carcinoma, and one undifferentiated carcinoma. Six patients exhibited a partial response (42.9 %: 95 % confidence interval [CI], 21.4-67.4) and the disease control rate was 85.7 % (60.0-96.0 %). After a median follow-up of 24.2 months, the median progression-free survival was 8.1 months (range, 2.6-12.2 months), and median overall survival was 30.0 months (range, 6.2-41.9 months). No significant correlation between biomarker expression and response was noted. However, thymidine synthase (TS)/dihydropyrimidine dehydrogenase and TS/orotate phosphoribosyltransferase were observed. CONCLUSIONS S-1 for refractory thymic carcinoma offered clinical activity and achieved an 85 % disease control rate. Although the biomarkers did not correlate with clinical outcome, the study results showed efficacy of S-1 as a cytotoxic chemotherapy for refractory thymic carcinoma, which warrants future investigation.

Abstract
Experiments by a four-pin probe and photodetachment technique were carried out to investigate the charged particle flows in the beam extraction region of a negative hydrogen ion source for neutral beam injector. Electron and positive ion flows were obtained from the polar distribution of the probe saturation current. Negative hydrogen ion flow velocity and temperature were obtained by comparing the recovery times of the photodetachment signals at opposite probe tips. Electron and positive ions flows are dominated by crossed field drift and ambipolar diffusion. Negative hydrogen ion temperature is evaluated to be 0.12 eV.

Abstract
Background Docetaxel monotherapy is one of the standard treatments for non-small-cell lung cancer in elderly patients. The addition of bevacizumab to docetaxel seems promising; however, the feasibility of this combination has not been investigated in such patients. Methods Patients with advanced non-squamous non-small-cell lung cancer aged 70 years or older who had not previously received cytotoxic chemotherapy were enrolled. Patients in the Level 0 cohort received docetaxel 60 mg/m2 and bevacizumab 15 mg/kg, whereas those in the Level-1 cohort received docetaxel 50 mg/m2 and bevacizumab 15 mg/kg. Chemotherapy was repeated 3 weekly for six cycles. The primary endpoint was toxicity and the secondary endpoints were response rate, progression-free survival, overall survival, and proportion of patients who underwent three or more cycles of chemotherapy. Results Twenty-one patients were enrolled from December 2010 to September 2012 at six institutes. Of the nine patients enrolled in Level 0, two experienced dose-limiting toxicity (febrile neutropenia and prolonged Grade 4 neutropenia in one patient, and Grade 3 infection in another patient) during the first cycle. Enrollment to the Level 0 cohort was terminated because two patients developed Grade 4 sepsis during later cycles. The remaining 12 patients were enrolled in the Level-1 cohort, in which two dose-limiting toxicities (prolonged Grade 4 neutropenia and Grade 3 increased aminotransferase level) were observed. No patient in the Level-1 cohort experienced Grade 4 nonhematologic toxicity. Grade 4 neutropenia occurred in 89 % of Level 0 patients and 50 % of Level-1 patients. The proportion of patients who experienced Grade 3/4 infection, febrile neutropenia or sepsis was 44 % in the Level 0 cohort, and 8 % in the Level-1 cohort. The overall response rate to chemotherapy and progression-free survival were 29 % (95 % CI, 11–52 %) and 5.9 months (95 % CI, 3.6–9.1 months), respectively. Efficacy outcomes did not differ significantly between the cohorts. Conclusions Toxicities were tolerable in level-1 cohort. The recommended dose of combination chemotherapy with docetaxel and bevacizumab for elderly patients was determined as 50 mg/m2 of docetaxel and 15 mg/kg of bevacizumab and toxicities were tolerable. Further studies are warranted. Trial registration UMIN Clinical Trial Registry; UMIN000004240.

Abstract
OBJECTIVES This study sought to compare the effect of paclitaxel-coated balloon (PCB) concentration on tissue levels and vascular healing using 3 different PCB technologies (In.Pact Pacific = 3 μg/mm(2), Lutonix = 2 μg/mm(2) and Ranger = 2 μg/mm(2)) in the experimental setting. BACKGROUND The optimal therapeutic dose for PCB use has not been determined yet. METHODS Paclitaxel tissue levels were measured up to 60 days following PCB inflation (Ranger and In.Pact Pacific) in the superficial femoral artery of healthy swine (18 swine, 36 vessels). The familial hypercholesterolemic swine model of superficial femoral artery in-stent restenosis (6 swine, 24 vessels) was used in the efficacy study. Two weeks following bare-metal stent implantation, each in-stent restenosis site was randomly treated with a PCB or an uncoated control balloon (Sterling). Quantitative vascular analysis and histology evaluation was performed 28 days following PCB treatment. RESULTS All PCB technologies displayed comparable paclitaxel tissue levels 4 h following balloon inflation. At 28 days, all PCB had achieved therapeutic tissue levels; however, the In.Pact PCB resulted in higher tissue concentrations than did the other PCB groups at all time points. Neointimal inhibition by histology was decreased in all PCB groups compared with the control group, with a greater decrease in the In.Pact group. However, the neointima was more mature and contained less peri-strut fibrin deposits in both 2-μg/mm(2) PCB groups. CONCLUSIONS Compared with the clinically established PCB dose, lower-dose PCB technologies achieve lower long-term tissue levels but comparable degrees of neointimal inhibition and fewer fibrin deposits. The impact of these findings in restenosis reduction and clinical outcomes needs to be further investigated.

Abstract
Prophylactic cranial irradiation (PCI) is an established part of standard therapy for small-cell lung cancer (SCLC). However, the concerns regarding severe late neurotoxicity following PCI have not yet been systematically investigated. Therefore, the aim of this study was to investigate the neurocognitive functioning of SCLC patients treated with PCI. Limited-disease SCLC (LD-SCLC) patients (n=40) treated at Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital (Tokyo, Japan) between January, 2004 and December, 2011 were retrospectively reviewed. A total of 18 LD-SCLC patients were treated with PCI (median age, 65.5 years; range, 52-75 years), whereas 22 LD-SCLC patients did not receive PCI (median age, 65.5 years; range, 57-84 years). The median follow-up for PCI and non-PCI patients was 22 months (range, 4-85 months) and 14.5 months (range, 2-49 months), respectively. Brain metastases occurred in 6 (33%) PCI patients and 11 (50%) non-PCI patients. In the PCI group, dementia occurred in 5 of the 12 PCI patients without brain metastases (42%, 3-40 months after PCI) and in 1 of the 11 non-PCI patients without brain metastases (9%, 4 months after initial treatment). The frequency of dementia in the PCI group was significantly higher compared with that in the non-PCI group (P=0.0357). In the PCI group, all the patients who developed dementia were aged >65 years (range, 66-75 years). Gait disturbance appeared in 25% of the PCI patients without brain metastases (9-27 months after PCI); these patients were also aged >65 years. Patients aged >65 years were significantly more likely to develop dementia (P=0.0028) and gait disturbance (P=0.0291). Therefore, neurotoxicity due to PCI tends to appear more frequently in older patients.

Abstract
Postcatheterization pseudoaneurysm is one of the most common vascular complications of peripheral angiographic procedures. An 83-year-old male received endovascular treatment (EVT) for a total occlusion lesion of left superficial femoral artery (SFA) due to intermittent claudication. After the subintimal angioplasty procedure with implantation of three self-expandable nitinol stents, angiography revealed contrast staining outside the stent margins. Duplex ultrasonography immediately after the procedure confirmed a pseudoaneurysm of 12 mm in diameter. There was no change in the size of pseudoaneurysm during the follow-up period. Four years after the initial procedure, he was admitted to our hospital because of swelling and pain in his left thigh. The angiography showed stent fracture at the proximal shaft of the stent. Furthermore, a fractured fragment of the stent was lying within the ruptured pseudoaneurysm, and active extravasation of contrast medium was identified. Surgical repair of the pseudoaneurysm was performed. We report a case of spontaneous pseudoaneurysm rupture of the SFA that had developed because of subintimal stent placement 4 years previously. If pseudoaneurysm is confirmed after EVT with subintimal stent placement, it should be treated by surgical or percutaneous methods, regardless of its size. <Learning objective: In general, conservative observation is thought to be reasonable when the size of pseudoaneurysm is small (<20 mm) in the absence of severe pain. However, repair of pseudoaneurysm should be considered, when the pseudoaneurysm was caused by arterial wall rupture after subintimal stent placement for a totally occluded lesion of the superficial femoral artery. It has a higher risk of spontaneous rupture during the long-term period.>.

Abstract
To date, there are no prospective studies on the relationship between plaque characteristics identified by 40 MHz IVUS and future adverse events. This prospective study evaluated the relationship between plaque morphology in nonculprit nonsignificant lesions, determined by 40 MHz IVUS, and long-term clinical outcomes. Consecutively, 45 patients who underwent 3-vessel intravascular ultrasound (IVUS) examinations were prospectively enrolled. Qualitative and quantitative IVUS analyses including scoring of echogenicity for assessment of plaque characterization were performed for each nonsignificant nonculprit lesion. The number, the length, the location (superficial or deep), and maximum arc were measured for each calcium deposit within plaques. Spotty calcification was defined as calcium deposits <90° and <6 mm in length. Primary end point was defined as nonsignificant nonculprit lesion-related revascularization (NNLR) during 6 years of follow-up. A total of 163 nonsignificant nonculprit lesions with mild to moderate stenosis were identified on baseline 3-vessel IVUS. Of those 163 lesions, six lesions required NNLR during the follow-up period. There were no differences in quantitative IVUS parameters including remodeling index, plaque burden, and echogenicity between lesions requiring and not requiring NNLR. However, deep spotty calcification was more frequently identified in lesions requiring NNLR than in those not requiring NNLR (33 vs. 8 %, P = 0.02). Spotty calcium deposits identified by 40 MHz IVUS predicted the need for NNLR during a 6-year follow-up period. This finding suggests that deep spotty calcium may be a surrogate marker for plaque progression and the subsequent need for revascularization in the future.

Abstract
AIMS To test the feasibility of a thoracoscopically assisted, off-pump, transcatheter ventricular reconstruction (TCVR) approach in an ovine model of left ventricular (LV) anteroapical aneurysm. METHODS AND RESULTS Myocardial infarction (MI) was induced by coil occlusion of the middle left anterior descending artery and diagonals. Two months after MI creation, TCVR was performed via a minimal thoracotomy in eight sheep. Under endoscopic and fluoroscopic guidance, trans-interventricular septal puncture was performed from the LV epicardial scar. A guidewire was externalised via a snare placed in the right ventricle from the external jugular vein. An internal anchor was inserted over the wire and positioned on the right ventricular septum and an external anchor was deployed on the LV anterior epicardium. Serial pairs of anchors were placed and plicated together to exclude the scar completely. Immediately after TCVR, echocardiography showed LV end-systolic volume decreased from pre-procedure 58.8±16.6 ml to 25.1±7.6 ml (p<0.01) and the ejection fraction increased from 32.0±7.3% to 52.0±7.5% (p<0.01). LV twist significantly improved (3.83±2.21 vs. pre-procedure -0.41±0.94, p=0.01) and the global peak-systolic longitudinal strain increased from -5.64% to -10.77% (p<0.05). CONCLUSIONS TCVR using minimally invasive access techniques on the off-pump beating heart is feasible and resulted in significant improvement in LV performance.
