Abstract
Symptomatic colorectal cancer in extremely elderly patients is difficult to treat. A 97-year-old woman was initially suspected of having appendicitis because of worsening right lower abdominal pain with persistent fatigue. After antimicrobial therapy, advanced cecum cancer with lymph node involvement was found. Palliative laparoscopy-assisted ileocecal resection without radical lymph node dissection was performed to prevent further inflammation. The patient was transferred to another hospital for rehabilitation on postoperative day 24, when she regained walking function. This palliative procedure can be an effective treatment for elderly patients with symptomatic advanced colon cancer.

Abstract
Abstract
Background
The second generation drug-eluting stent (G2-DES) has been reported as superior to the first generation drug-eluting stent (G1-DES) in mid-term outcomes. However, the late-term outcomes between G1-DES and G2-DES in two-stenting for coronary bifurcation lesions are not well studied.
Purpose
To evaluate the late catch-up phenomenon and late-term target lesion revascularization (TLR) of two-stenting for coronary bifurcation lesions between G1-DES and G2-DES.
Methods
This study included 1133 lesions in 1089 patients undergoing drug eluting stent implantation with two stenting from 2004 to 2016. These consisted of 496 G1-DES implanted lesions and 637 G2-DES implanted lesions. Late-term follow-up angiography was performed without in-stent restenosis (ISR) and TLR at mid-term follow-up in 582 lesions (242 G1-DES lesions and 340 G2-DES lesions). ISR was defined as more than 50% restenosis. Late catch-up phenomenon was defined as ISR without ISR within 1 year following index stent implantation. Late-term TLR was defined as from 1 to 5 year TLR. Bifurcation lesions were defined as the main branch ranging from the proximal stem to the distal main branch with boundaries defined by 5 mm proximal and distal to the stent-implanted area, and the side branch ranging from the bifurcation carina to the distal side branch with boundaries defined by the carina and 5 mm distal to the stent-implanted area.
Results
The median follow-up duration was 5.1 years (the first and third quarters, 3.2 and 7.1 years). The late-catch up phenomenon rate significantly differed between the G1-DES and G2-DES groups (16.9% vs 8.4%, p=0.001). A significant difference in late catch-up between the same two groups was also observed in bifurcation lesions of the main branch (5.0% vs 0.6%, p=0.001) and side branch (10.3% vs 5.6%, p=0.033), respectively. The 5-year cumulative rates also differed between the two groups in TLR (8.2% vs 3.7% log-rank p=0.001), and late-term TLR (7.0% vs 3.6% log-rank p=0.001).
Conclusion
Two-stenting using G2-DES, compared with G1-DES, significantly reduced late-term restenosis and TLR. The restenosis rate in bifurcation area may be associated with differences between two groups in late-term outcome.

Abstract
Abstract
Background
Coupled abnormalities in arterial and left ventricular (LV) stiffness characterize aging and heart failure with preserved ejection fraction. We hypothesized that two measures of aortic stiffness, pulse wave velocity (PWV; reflecting segmental arterial wall stress in late systole) and total arterial compliance (TAC; reflecting distensibility of entire arterial system) differentially relate to cardiac structure and function in the elderly.
Methods
Among participants in the Atherosclerosis Risk In Community (ARIC) study, we assessed the cross-sectional relationship of carotid-femoral PWV (cfPWV) and TAC with echocardiographic measures of cardiac structure and function using multivariable linear regression adjusting for demographics and co-morbidities. TAC defined as stroke volume over pulse pressure [mL/mmHg]. Exclusions were LVEF <50%, prevalent HF, ≥moderate valvular disease.
Results
Of the 4,141 participants included in this study, mean age was 75±5 years, 41% were male, and 80% were white. Mean values were: cfPWV: 11.7±3.4 m/sec; TAC: 1.1±0.3 mL/mmHg. Greater cfPWV was associated with greater LV mass, worse systolic function, and worse diastolic function (Table). In contrast, worse TAC was not related to LV structure and did not demonstrate consistent relationships with measures of LV diastolic function, but was associated with worse LV longitudinal strain.
Echo measures cfPWV (1SD increase) TAC (1SD decrease) β Coefficient p-value β Coefficient p-value Cardiac structure Mean wall thickness, cm 0.10 <0.001 -0.01 0.499 LVMI, g/m2 0.04 0.016 0.02 0.299 LVEDVI, ml/m2 -0.07 <0.001 -0.02 0.332 LV systolic function LVEF (Simpson's), % -0.04 0.01 -0.16 <0.001 Longitudinal strain, % 0.14 <0.001 0.19 <0.001 LV diastolic function Septal e', cm/sec -0.08 <0.001 -0.02 0.169 E/e' septal 0.04 0.005 -0.02 0.138 LAVI, ml/m2 -0.05 0.003 -0.04 0.026
Conclusion
Two non-invasive measures of aortic stiffness, cfPWV and TAC, demonstrate differential associations with LV structure and function in late life. Greater cfPWV is more robustly associated with LV structure and function than TAC.

Abstract
Abstract
Background
Electrocardiographic (ECG) strain pattern has recently been associated with increased adverse outcome in aortic stenosis (AS) and after surgical aortic valve replacement (AVR). However, the relation linking ECG strain and cardiovascular MACE in patients with transcatheter aortic valve replacement (TAVR) has not been yet described.
Objectives
The aim of our study was to determine the impact and incremental value of ECG Strain pattern in predicting adverse outcome after TAVR.
Methods
585 patients with severe AS (mean age: 83±7 male 39.8%) were enrolled from November 2012 to May 2018. ECG strain pattern was defined as ≥1 mm concave down-sloping ST-segment depression and asymmetrical T-wave inversion in the lateral leads. Patients with baseline left bundle branch block (LBBB), right bundle branch block (RBBB) or ventricular paced rhythm were excluded. All patients underwent transthoracic echocardiography (TTE) before TAVR and at 30 days follow up. The primary endpoints of the study were the overall all-cause mortality after TAVR, rehospitalization for Hearth failure (HF), myocardial infarction and stroke.
Results
178 (30.4%) patients were excluded from analyses owing to the presence of either LBBB (n=103) or RBBB (n=75). Among the 407 remaining patients, 106 had ECG strain pattern (26.04%). Patients with ECG strain were significantly younger (81.6±8 years vs 83.5±6.8 years; p=0.022), had lower BMI (23±4.5 kg.m2 vs 27.9±6.8 kg.m2; p=0.02) more severe AS (mean gradient 52.3±15.2 mmHg vs 47.9±11.8 mmHg; p=0.003), significant lower LVEF (51.8±15% vs 58.4±10.7%; p<0.001). Left ventricular hypertrophy (LVH) was more frequent in patients with ECG Strain (indexed left ventricular mass (135.9±33.4 g.m2 vs 123.6±31.9 g.m2; p=0.002)). Death from any cause (22 (20.8%) vs 61 (20.3%); p=0.508) did not differ significantly between groups. Major adverse cardiovascular events (MACE) including death, stroke and heart failure at 1 month showed similar incidence (7 (6.6%) vs 17 (5.6%), p=0.439). Rehospitalization for hearth failure (HF) was significantly higher (33 (31.1%) vs 33 (11%); p<0.001) in patients with ECG strain pattern. In univariate model, ECG Strain was a strong predictor of rehospitalization for HF (HR 2.621 95% CI (1.607–4.277), p=0.001), independently of LVH assessed either by ECG criteria (HR 1.181 95% CI (0.698–1.997; p=0.536) or TTE (HR 1.557 95% (CI 0.701–3.458; p=0.277). ECG Strain remained associated with a higher risk of rehospitalization for hearth failure in multivariate analyses (HR 2.747 95% (CI 1.614- 4.674); p<0.001)
Conclusion
In patients with AS eligible for TAVR, ECG Strain Pattern is frequent and associated with an increased risk of post interventional heart failure regardless of preoperative LVH. ECG Strain pattern represents an easy, objective, reliable and low-cost tool to identify patients who may benefit from an extend and intensified post-interventional follow-up.

Abstract
Abstract
Background
Despite recommendations from clinical practice guidelines, there is scant evidence confirming the effects of vasodilators on clinical outcomes in patients with acute heart failure (AHF).
Purpose
We sought to investigate the effects of intravenous vasodilators on clinical outcomes and to identify the potential patient populations that would benefit from its use.
Methods
Data of 26 212 consecutive patients urgently hospitalized for AHF between 2009 and 2015 were extracted from a multicenter data registration system (Tokyo Cardiovascular Care Unit Network Database, including 72 institutions within the Tokyo metropolitan area in Japan). Patients who did not present with typical AHF episodes, including those without pulmonary congestion on physical and/or chest X-ray and serum B-type natriuretic peptide level <500 pg/ml, as well as those who had hypotension and/or hypoperfusion (systolic blood pressure [SBP] <100 mmHg) as dominant presentation, were excluded. Propensity scores were calculated with multiple imputation and 1:1 matching performed between patients with and without vasodilators. The primary endpoint was in-hospital mortality and the secondary endpoints were length of intensive/cardiovascular care unit (ICU/CCU) stay and hospital stay.
Results
Overall, 8 863 patients were included in the present analysis; they were predominantly male (57%) with a median age of 79 (interquartile range: 70–86) years. Compared with the group without vasodilator use, the vasodilator group had higher SBPs and heart rates and higher frequency of assisted ventilation use, but lower frequency of intravenous diuretics use. After propensity score matching, there were no significant differences in in-hospital mortality rates (7.8% vs. 8.9% in patients without vasodilators, p=0.16) or in length of ICU/CCU stay (5.8 days vs. 5.4 days, p=0.44) and hospital stay (22.7 days vs. 23.8 days, p=0.22) between the groups. However, in subgroup analyses, favorable impacts of vasodilator use on in-hospital mortality were observed among patients who had higher SBPs and among those who had no atrial fibrillation upon admission (Figure). In addition, vasodilators were likely to be more effective in AHF patients with SBP increasing; while levels below 140 mmHg of SBP appeared to be associated with an increased risk for mortality among patients treated with vasodilators compared with those without vasodilators.
Figure 1
Conclusions
In patients with AHF, vasodilator use was not universally associated with improved in-hospital outcomes; however, its effect was dependent of individual clinical presentation. Detailed phenotyping might aid tailoring of treatment strategies for patients with AHF.

Abstract
The gastrointestinal absorption of phenytoin (PHT), an antiepileptic drug, is often affected by its interaction with co-administered enteral nutrients through a nasogastric (NG) tube, resulting in decreased plasma PHT concentration. In this study, we measured the recovery rate (%) of PHT (Aleviatin® powder) passed through an NG tube when co-administered with distilled water or enteral nutrients (F2α®, Racol® NF, Ensure Liquid® and Renalen® LP). We also measured plasma PHT levels in rats, after oral co-administration of PHT with enteral nutrients. We demonstrate that PHT recovery rate was close to 100 % in all cases after passage through the NG tube. In the rat study, the AUC0→∞ of PHT concentration after oral administration significantly decreased when it was co-administered with F2α® and Racol® NF compared to distilled water. However, the AUC0→∞ of PHT was unchanged when co-administered with F2α® 2 h after initial PHT administration. We therefore conclude that the co-administration of PHT with F2α® and Racol® NF caused a reduction in the absorption of PHT from the gastrointestinal tract to the blood, without adsorption to the NG tube. The administration of enteral nutrients 2 h after PHT is one clear way to prevent a decrease in plasma PHT concentration.

Abstract
Previous studies highlighted that aminopeptidase N (APN)/CD13 acts as a scavenger in the survival of hepatocellular carcinoma (HCC) stem cells by reducing reactive oxygen species (ROS) levels. Hence, it has been proposed that APN/CD13 inhibition can increase cellular ROS levels and sensitize cells to chemotherapeutic agents. Although ubenimex, also known as bestatin, competitively inhibits proteases such as APN/CD13 on the cellular membrane and it is clinically used for patients with acute myeloid leukemia and lymphedema, research has demonstrated that higher concentrations of the agent induce the death of APN/CD13+ HCC stem cells. In this study, we developed a poly(ethylene glycol)-poly(lysine) block copolymer-ubenimex conjugate (PEG-b-PLys(Ube)) to increase the efficacy of reagents in APN/CD13+ cancer stem cells. Exposure to PEG-b-PLys(Ube) increased the intracellular ROS concentration by inhibiting APN enzyme activity, permitting the induction of apoptosis and attenuation of HCC cell proliferation. In addition, PEG-b-PLys(Ube) exhibited a relatively stronger antitumor effect in mice than PEG-b-PLys alone or phosphate-buffered saline. Moreover, an isobologram analysis revealed that combinations of fluorouracil, cisplatin, or doxorubicin with PEG-b-PLys(Ube) exhibited synergistic effects. This study demonstrated that PEG-b-PLys(Ube) does not impair the properties of ubenimex and exerts a potent antitumor effect.

Abstract
Abstract
Although the stiffness of tissues likely is involved in the malignant behavior of tumors, it remains to be clarified which molecules control the nature, how it is involved in the invasiveness of tumors, or whether any marker is available for the prediction of cancer patient prognosis. In the present study, we studied the role of Myl9, a non-muscle-type, myosin light chain by the experiment in vitro, and assessed the usefulness in the stratification of patients in vivo as the precision medicine. Given that Myl9 is involved in the contraction of cell skeleton, cell hardness, and alterations of cell morphology in various tissues, we first examined whether the expression of the Myl9 is associated with the clinical status of tumors by immunohistochemistry. The results of 45 cases with colon cancer and pancreatic cancer indicated that the increased expression of Myl9 is associated significantly with a reduced provability of overall survival and disease-free survival of those cancers. Moreover, we noted the differential expression of Myl9 in epithelial cancer cells and mesenchymal fibroblasts, i.e., the accumulation of Myl9 staining in cell nuclei of fibroblasts. The experiment of 3-dimensional culture with cancer cells and fibroblasts confirmed the results. Furthermore, we investigated whether Myl9 overexpression is involved in the biologic behavior of gastrointestinal cancer cells. The results showed that the rentiviral-mediated overexpression of Myl9 resulted in an increase of cell proliferation and invasion as well as tumorigenicity in mice. The present study indicates that Myl9 protein can play a fundamental role in the malignant behaviors of gastrointestinal cancer cells.

Abstract
Hepcidin and ferroportin, which are known as key iron regulators, may be used in future treatments of pancreatic ductal adenocarcinoma. Iron is essential for life support; it helps oxygen molecules bind to hemoglobin and acts as an important catalytic enzyme center. However, iron overload is a risk factor for cancer, possibly through the generation of reactive oxygen species (ROS). Hepcidin, which is a peptide hormone mainly generated by the liver, inhibits iron absorption via enterocytes and iron release from macrophages. Notably, hepcidin regulates iron homeostasis in the body by regulating the iron transporter ferroportin. In the present study, it was assumed that high hepcidin expression and low ferroportin expression result in malignancy. Therefore, it was examined whether hepcidin and ferroportin expression levels were correlated with the prognosis of pancreatic cancer in patients. Results revealed that high hepcidin expression levels and low ferroportin expression levels in pancreatic cancer tissue were significantly associated with poor prognosis in the analyses of overall survival (P=0.0140 and 0.0478, respectively). Additionally, there was no significant difference in disease-free survival in the hepcidin- and ferroportin-staining groups. Hepcidin expression correlated with the pathological stage and vascular invasion (P=0.0493 and 0.0400, respectively), and ferroportin expression was correlated with age (P=0.0372). Multivariate analysis of overall survival in the hepcidin-staining group revealed that pathological N factor (pN), adjuvant chemotherapy, and hepcidin expression were independent prognostic factors (P=0.0450, 0.0002, and 0.0049, respectively). Similarly, multivariate analysis of overall survival in the ferroportin-staining group revealed that vascular invasion, and ferroportin expression were independent prognostic factors (P=0.0028, P<0.0001, and P=0.0056, respectively). Thus, hepcidin and ferroportin expressions might be novel prognostic indicators for pancreatic cancer.

Abstract
The aim of this study was to investigate the incidence of anterior disc displacement without reduction (ADDwoR) of the temporomandibular joint (TMJ) in patients with dentofacial deformity. Eighty-eight female patients (176 joints) with skeletal class III malocclusion and 33 female patients (66 joints) with skeletal class II malocclusion, with or without anterior open bite and asymmetry, were evaluated. Magnetic resonance imaging (MRI) of the TMJ was used to diagnose ADDwoR. A statistical analysis was performed to examine the relationship between ADDwoR and skeletal structure. ADDwoR was present in 37 of the 66 joints (56.1%) in class II compared to 34 of the 176 joints (19.3%) in class III (P<0.05). In class III, ADDwoR was significantly more common in joints with mandibular asymmetry (24/74; 32.4%) than in joints with open bite (9/62; 14.5%) and joints with open bite and without mandibular asymmetry (1/38; 2.6%). In class II, ADDwoR was significantly less common in joints with mandibular asymmetry and without open bite (1/8; 12.5%). ADDwoR was only observed on the deviated side in both class III and class II with mandibular asymmetry. The prevalence of ADDwoR differed according to the dentofacial morphology.

Abstract
For a sagittal split ramus osteotomy to be secure, the relation between the outer and inner contours of the cortex at the inferior border of the mandible is critical. The lowest point of the outer contour is not always immediately below that of the inner contour, and the former is placed more lingually than the latter in about a third of all cases. This tendency is much more noticeable in skeletal class I and II malocclusions than class III. It is therefore important to examine the lowest point of the inferior border in every case, and to carry the inferior part of the buccal cut on to the lingual side if necessary.

Abstract
Simultaneous recordings of neural activity at large scale, in the long term and under bio-safety conditions, can provide essential data. These data can be used to advance the technology for brain-machine interfaces in clinical applications, and to understand brain function. For this purpose, we present a new multichannel neural recording system that can record up to 4096-channel (ch) electrocorticogram data by multiple connections of customized application-specific integrated circuits (ASICs). The ASIC includes 64-ch low-noise amplifiers, analog time-division multiplexers, and 12-bit successive approximation register ADCs. Recorded data sampled at a rate of 1 kS/s are multiplexed with time division via an integrated multiplex board, and in total 51.2 Mbps of raw data for 4096 ch are generated. This system has an ultra-wideband (UWB) wireless unit for transmitting the recorded neural signals. The ASICs, multiplex boards, and UWB transmitter unit are designed with the aim of implanting them. From preliminary experiments with a human body-equivalent liquid phantom, we confirmed 4096-ch UWB wireless data transmission at 128 Mbps for distances below 20 mm .

Abstract
We evaluated the effects of dutasteride on the genitourinary tract using fifteen 8-week-old male Sprague-Dawley rats. Animals were divided into three groups comprising five animals each and treated as follows. Group A was a control group, members of Group B received oral administration of dutasteride 0.1 mg/kg/day from the age of 8 to 16 weeks, and members of Group C were castrated at the age of 8 weeks. All rats were killed at the age of 16 weeks for the sample collection of blood, bladder, prostate, seminal vesicles, and penis. Then, we evaluated the pathological examination for evaluating the tissue fibrosis and hormonal receptor expression. The results showed that the mean size of the prostate and seminal vesicles was smaller in Group B and Group C than in Group A. Serum and tissue concentrations of both testosterone and dihydrotestosterone were remarkably reduced in serum and all tissues in Group C compared with Group A. On the other hand, in Group B, only dihydrotestosterone was reduced in serum and penis. Histopathological examination revealed that Group C showed statistically significant histological changes, such as an increase in fibrotic tissue in the bladder, prostate, and penis. Similarly, Group B showed fibrotic changes in the prostate and penis compared with the Group A. Immunofluorescent staining revealed that the androgen receptor was more strongly expressed than the estrogen receptor beta in Group A. On the other hand, in Group C, weak expression of the androgen receptor and strong expression of the estrogen receptor beta was noted. In Group B, these changes were noted in the prostate and penis. These findings suggest that dutasteride cause morphological changes not only in prostate but also in penis. These changes are associated with altered expression patterns of androgen receptor and estrogen receptor.

Abstract
To realize a low-invasive and high accuracy BMI (Brain-machine interface) system, we have already developed a fully-implantable wireless BMI system which consists of ECoG neural electrode arrays, neural recording ASICs, a Wi-Fi based wireless data transmitter and a wireless power receiver with a rechargeable battery. For accurate estimation of movement intentions, it is important for a BMI system to have a large number of recording channels. In this paper, we report a new multi-channel BMI system which is able to record up to 4096-ch ECoG data by multiple connections of 64-ch ASICs and time division multiplexing of recorded data. This system has an ultra-wide-band (UWB) wireless unit for transmitting the recorded neural signals to outside the body. By preliminary experiments with a human body equivalent liquid phantom, we confirmed 4096-ch UWB wireless data transmission at 128 Mbps mode below 20 mm distance.

Abstract
We evaluated the feasibility of stenting in four patients. Two cases were vertebral osteal stenosis and the others were carotid stenosis at high position with ulcers. We placed balloon expandable coronary stents by a bared stent technique. The mean preprocedural stenosis (86.58%) was reduced to 13.05%. Patients were examined clinically and angiographically at 1, 3 and 6 months after stenting. There was no minor nor major stroke during and after the procedures. Asymptomatic restenosis occurred in the cases of proximal vertebral arteries. One of these patients needed to repeat balloon dilatation. There were no angiographic restenoses in the location of stenting in the carotid artery. In the treatment for atherosclerotic stenoses, stent placement is a feasible and safe method. However restenosis in a vertebral osteal lesion should be carefully followed after stent placement.

Abstract
The Guidelines for Colorectal Cancer Treatment list indication and curative resection criteria for the endoscopic resection of mucosal and submucosal invasive colorectal cancers. Here, we report the case of a woman who underwent endoscopic mucosal resection (EMR) but should have undergone curative resection because the submucosal invasion depth in this case was 1,200 mm; however, she did not undergo additional curative surgery. Although liver and lymph node metastases were observed 7 years later, we were able to resect all of these tumors after neoadjuvant chemotherapy. We strongly recommend additional curative surgery for patients who fulfill the criteria for curative resection after EMR because of the very high recurrence rates in such cases.

Abstract
A 68-year-old man diagnosed with type 0-Ⅰgastric cancer by gastrointestinal endoscopy underwent urgent distal gastrectomy due to a perforation during endoscopic submucosal resection. Pathological examination revealed pT3N2M0, pStage ⅢA. TS-1 was administered as adjuvant chemotherapy. Laboratory examinations 10 months after surgery revealed leukocytosis (19,100/mL). Positron emission tomography-CT demonstrated metastases in the bone marrow and ascending colon as well as around the liver. Chemotherapy using nab-PTX had poor efficacy and the leukocytosis worsened. Serum granulocyte- colony stimulating facto (r G-CSF) was high at 1,640 pg/mL, and immunohistochemical staining was positive for G-CSF. Thus, the patient was diagnosed with G-CSF-producing gastric cancer. The tumor was also positive for HER2 antibody by immunohistochemical staining. Combination therapy using TS-1 plus CDDP plus trastuzumab resulted in a good response, and the leukocytosis and elevated serum G-CSF gradually improved. The patient is living 30 months postoperatively and remains on chemotherapy.

Abstract
The patient was an 86-year-old woman. She underwent right breast-conserving surgery and sentinel lymph node biopsy for breast cancer in August 2006. The pathological diagnosis was invasive ductal carcinoma, T1N0M0, Stage Ⅰ, ER (+), PgR (-), HER2 (-). She was treated with tamoxifen for 5 years as adjuvant therapy and showed no signs of recurrence. In November 2014, CA15-3 was elevated and an accumulation of FDG in the right paracolic sulcus was observed on PET-CT. Peritoneal metastasis of breast cancer was suspected, and an operation was performed for a definitive diagnosis. During the operation, the tumor was seen on the paracolic sulcus, and laparoscopic-assisted right hemicolectomy was performed. A poorly differentiated adenocarcinoma was diagnosed by pathological examination, and immunostaining results were as follows: CK7(+), CK20(-), mammaglobin (-), GCDFP-15 (-), ER (-), PgR (-), and HER2 (-). Because there was no original lesion other than the breast cancer, the tumor was diagnosed as a metastasis of breast cancer. The frequency of peritoneal metastasis of breast cancer is low. In this case, pathological diagnosis was necessary for a definitive diagnosis. A change of subtype was also confirmed, and the treatment strategy was decided appropriately. Surgical resection should be considered for peritoneal metastasis of breast cancer when the operation can be performed safely.

Abstract
An 81-year-old woman was admitted for leg edema. She was found to have membranous glomerulonephritis with advanced gastric cancer after renal biopsy and endoscopic examination. Serum albumin was 1.4 g/dL and total protein was 4 g/dL on admission. After albumin was administered, distal gastrectomy was performed. Albumin administration continued post-operatively. The post-operative course was unremarkable and she was discharged on post-operative day 19. Six months after the operation, serum albumin gradually increased and uric protein volume decreased. Possible remission of membranous glomerulonephritis with gastric cancer can be expected after gastrectomy but careful perioperative management is required.

Abstract
Pancreatic ductal carcinoma is a highly aggressive cancer, with one of the highest mortality rates among gastrointestinal cancers. Nab-paclitaxel plus gemcitabine (GEM) significantly improved overall survival, progression-free survival, and response rate in a phase Ⅲ trial in 151 community and academic centers in 11 countries. As a result, nab-paclitaxel plus GEM was approved for use in December 2014 in Japan. We report a case of a patient with pancreatic cancer who underwent this chemotherapy. A 47-year-old man was admitted to our hospital for evaluation of pancreatic lesions. Computed tomography revealed a hypoattenuating tumor in the body of the pancreas. After the patient underwent preoperative chemoradiotherapy under the diagnosis of cStage Ⅳa cancer, we planned to perform distal pancreatectomy. However, this case was inoperable because we found 3 liver metastases during surgery. On postoperative day 14, we treated the patient with nab-paclitaxel plus GEM. Grade 2 toxicities included neutropenia, diarrhea, and peripheral neuropathy, but serious adverse events did not occur. The progression-free survival was 5 months. He remained alive for 7 months after the chemotherapy. In patients with metastatic pancreatic adenocarcinoma, nab-paclitaxel plus GEM can be considered as the standard treatment.

Upper gastrointestinal endoscopy revealed a type 2- like ulcerative lesion in the posterior wall of the upper and middle part of the stomach. Endoscopic biopsies showed malignant T-cell lymphoma histologically. A chest CT scan revealed a nodule in the apex of right lung, suggestive of primary lung cancer. A total gastrectomy with D2 lymphadenectomy and distal pancreatectomy with splenectomy was performed. Seventy-three days after surgery, the patient developed a lung abscess in the middle lobe of the right lung. A wedge-shaped resection of the upper lobe and total resection of the middle lobe of the right lung was performed. Histological examination revealed a primary pulmonary mucosa-associated lymphoid tissue lymphoma in the upper lobe of right lung and an abscess caused by Pseudomonas aeruginosa in the middle lobe of the right lung. Twelve months after surgery the man died of suffocation because of aspiration due to esophageal stenosis caused by progression of metastasis of the paraesophageal lymph node.

Abstract
The objective of this study was to characterise the status of health-related quality of life (HRQOL) in Japanese men with late-onset hypogonadism (LOH) treated with testosterone replacement therapy (TRT). HRQOL in 69 consecutive Japanese men with LOH undergoing TRT for at least 6 months was prospectively evaluated before and 6 months after the initiation of TRT using the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8). All eight-scale scores except for bodily pain (BP) in the 69 patients at 6 months after the introduction of TRT significantly improved compared with those before TRT; however, all scale scores except for BP in the 69 patients were significantly inferior to those in age-matched Japanese controls irrespective of the timing of SF-8. Multivariate analyses of several parameters revealed that both age and Aging Male Symptom (AMS) score had an independent impact on mental health (MH), despite the lack of an independent association between any score and the remaining factors examined. TRT appeared to significantly improve the status of HRQOL in men with LOH; however, even after the introduction of TRT, HRQOL associated with MH remained significantly impaired in elderly men and/or those with a high AMS score.

Abstract
The objectives of this study were to determine whether the inhibition of clusterin expression in rat Sertoli cells enhances heat stress-induced apoptosis. The scrotums of rats were immersed in a water bath of 43 °C for 15 min. Testicular weight and germ cell number markedly decreased after the heat treatment in a time-dependent manner. In contrast, clusterin mRNA and protein expression levels were significantly up-regulated and peaked on day 21. The apoptotic index was markedly increased 1 day after the heat treatment. We then purified Sertoli cells from the rat testes, and an expression vector containing siRNA targeting the clusterin gene was transiently transfected into Sertoli cells. Following exposure to heat stress at 41 °C for 12 h, clusterin mRNA was markedly up-regulated after transfection with the control vector; however, the transfection of siRNA targeting the clusterin resulted in >70% reduction in the expression of clusterin mRNA. Furthermore, the apoptotic index in these Sertoli cells was significantly higher after the treatment with siRNA targeting the clusterin than control, and the most prominent difference was observed within 24 h after the heat treatment. These results suggest that an increase in the secretion of clusterin by Sertoli cells protects the testes from heat stress-induced injury.

Abstract
Far-upstream element-binding protein-interacting repressor (FIR) is a transcription factor that inhibits c-Myc expression and has been shown to have antitumor effects in some malignancies. Here, we evaluated the antitumor effects of FIR using fusion gene-deleted Sendai virus (SeV/ΔF) as a nontransmissible vector against head and neck squamous cell carcinoma (HNSCC). Using in vitro and in vivo xenograft mouse models, we observed efficient expression of green fluorescent protein (GFP) following transduction with the SeV/ΔF vector encoding GFP (GFP-SeV/ΔF) into HNSCC cells. In vitro and in vivo studies revealed that administration of the FIR-encoded SeV/ΔF (FIR-SeV/ΔF) vector exerted significant antitumor effects, suppressed c-Myc expression and induced apoptosis in HNSCC. Additionally, the antitumor effects of FIR or the expression of GFP following administration of the FIR- or GFP-SeV/ΔF vector, respectively, were dependent on the multiplicity of infection or titer. Furthermore, the SeV/ΔF vector itself had no cytotoxic effects. Therefore, the SeV/ΔF vector may be safe and useful for the treatment of HNSCC, allowing for high-titer SeV/ΔF vector administration for anticancer gene therapy. In addition, SeV/ΔF vector-mediated FIR gene therapy demonstrated effective tumor suppression in HNSCC, suggesting that this therapy may have the potential for clinical use as a novel strategy for HNSCC treatment.
