Abstract
Objective In Japan, pleurodesis is often performed using OK-432. However, OK-432 may cause severe chest pain and fever. The risk factors for these complications are unclear. The aim of this study was to identify the risk factors for chest pain and fever caused by pleurodesis with OK-432. Methods The clinical data of 94 patients who underwent pleurodesis with OK-432 were retrospectively analyzed. Patients who developed chest pain (indicated by a record of rescue pain medication) and/or fever (a recorded temperature of >38°C) were identified. A logistic regression analysis was performed to determine the risk factors for these complications. Results Rescue medication for chest pain was required by 43.6% of the patients and 40.4% developed pyrexia after pleurodesis with OK-432. The univariate analysis showed that the likelihood of requiring rescue medication for chest pain was significantly increased in patients of <70 years of age (p=0.028) and in those who were not premedicated with a nonsteroidal anti-inflammatory drug (NSAID; p=0.003). Age <70 years (adjusted odds ratio 2.97, 95% confidence interval 1.10-8.00, p=0.031) and a lack of premedication with an NSAID (adjusted odds ratio 4.21, 95% confidence interval 1.47-12.04, p=0.007) remained significant factors in a multivariate analysis. The absence of NSAID premedication was the only statistically significant risk factor for fever in the univariate analysis (p=0.034). The multivariate analysis revealed no significant risk factors for fever. Conclusion The results of the present study suggest that premedication with an NSAID might be useful for preventing the chest pain caused by pleurodesis with OK-432. Furthermore, caution is advised when managing chest pain in adults of <70 years of age. Prospective studies should be performed to further investigate this issue.

Abstract
Adjuvant cisplatin-vinorelbine chemotherapy has been shown to be effective in patients with completely resected non-small cell lung cancer (NSCLC) in several Phase III trials, but not yet in the Japanese population. Pharmacists are expected to assist patients with completion of adjuvant chemotherapy. The aim of this retrospective study was to evaluate the compliance with and safety of adjuvant cisplatin-vinorelbine chemotherapy in Japanese patients and to evaluate the contribution of pharmacists to completion of treatment. Thirty-four patients with NSCLC who received adjuvant cisplatin-vinorelbine chemotherapy at Kyorin University Hospital between January 2006 and June 2015 were reviewed. The treatment schedule comprised cisplatin 80 mg/m2 on day 1 and vinorelbine 25 mg/m2 on days 1 and 8 every 3 weeks. Four 3-week cycles were planned. A pharmacist provided guidance to all patients and monitored them for adverse effects thereafter. The pharmacist intervened with advice to doctors as necessary. The 4 cycles were administered in 67.6% of cases. There were no treatment-related deaths. The main grade 3 or 4 toxicities were neutropenia (76.5%) and anorexia (38.2%). The most common reason for discontinuation and dose reduction was anorexia. There were 56 instances of pharmacist intervention. In total, 96.4% of the pharmacist interventions were implemented by doctors, which included administration of an antiemetic on 15 occasions and hot fomentation for prevention of vasculitis on 7 occasions. Adjuvant cisplatin-vinorelbine chemotherapy was tolerated by most patients but was discontinued because of adverse events in some. Pharmacist intervention aids completion of planned chemotherapy and management of treatment-related adverse events.

Abstract
We describe the possibility of high-sensitivity noninvasive blood glucose measurement based on photoacoustic spectroscopy (PAS). The demand for noninvasive blood glucose-level measurement has increased due to the explosive increase in diabetic patients. We have developed a noninvasive blood glucose-level measurement based on PAS. The conventional method uses a straight-type resonant cell. However, the cell volume is large, which results in a low detection sensitivity and difficult portability. In this paper, a small-sized Helmholtz-type resonant cell is proposed to improve detection sensitivity and portability by reducing the cell dead volume. First, the acoustic property of the small-sized Helmholtz-type resonant cell was evaluated by performing an experiment using a silicone rubber. As a result, the detection sensitivity of the small-sized Helmholtz-type resonant cell was approximately two times larger than that of the conventional straight-type resonant cell. In addition, the inside volume was approximately 30 times smaller. Second, the detection limits of glucose concentration were estimated by performing an experiment using glucose solutions. The experimental results showed that a glucose concentration of approximately 1% was detected by the small-sized Helmholtz-type resonant cell. Although these results on the sensitivity of blood glucose-level measurement are currently insufficient, they suggest that miniaturization of a resonance cell is effective in the application of noninvasive blood glucose-level measurement.

Abstract
Introduction: Little is understood about the early molecular drivers of the triple negative breast cancer making identification of women at risk and development of targeted therapy for prevention a significant challenge. Methods: Here, by deep sequencing of TNBC- cell line based breast cancer progression system we have identified miRNA-29c and its functional gene targets to be potentially involved in the normal to preneoplastic transition during TNBC progression. We have used cell line based functional assays that are relevant in early tumorigenesis such cell proliferation (ki67), and colony formation assay to study the growth inhibitory potential of these miRNA and their gene targets. To identify direct gene targets of miRNA-29c, we cloned the 3'untranslated region containing miRNA-29c binding sites from predicted gene targets in a luciferase reporter vector, pmiRGLO and studied the potential of miRNA-29c overexpression on the repression of luciferase reporter activity indicating their direct gene regulation. Results: Our deep sequencing results and their further validation by QPCR revealed miRNA-29c to be lost during the TNBC progression, and its forced expression to inhibit cell proliferation and colony formation of preneoplastic (MCF10AT1) and ductal carcinoma in situ (MCF10DCIS) cells. We found miRNA-29c to directly bind in 3'UTR of TGIF2, CREB5, AKT3 and CDK6 and regulate their expression as shown by our luciferase assays. We also found miRNA-29c binding to 3'UTR of these gene targets to be functionally relevant as TGIF2, CREB5 and AKT3 were able to rescue the inhibition in cell proliferation and colony formation assay caused by loss of miRNA-29c in preneoplastic cells. Further confirming the relevance of these miRNA-29c gene targets and pathways in TNBC tumorigenesis, inhibition of PI3K, which is upstream of AKT3, inhibits cell proliferation in MCF10AT1 and DCIS cells. We also examined the regulation of tumor suppressor miRNA-29c to study the mechanisms responsible for its loss during breast cancer development. We found c-myc and EZH2 driven epigenetic mechanism as well as DNA methylation in part to cause the loss of miRNA-29c during TNBC progression. Consistently, we found a pan HDAC inhibitor and a DNA methylation inhibitor to relieve the suppression of miRNA-29c. Conclusions: Together, these results indicate that loss of miRNA-29c plays a central role in preneoplastic development of breast cancer and efforts directed at inhibition of its target pathways or rescue of miRNA-29c itself may provide novel opportunities for prevention of TNBC.Introduction: Little is understood about the early molecular drivers of the triple negative breast cancer making identification of women at risk and development of targeted therapy for prevention a significant challenge.

Abstract
OBJECTIVES We developed a modified pleural tent (m-tent) procedure and used it in our hospital in almost 30 consecutive patients with spontaneous pneumothorax. The objective of this study was to clarify the feasibility and effectiveness of a thoracoscopic m-tent for the treatment of spontaneous pneumothorax. METHODS From July 2013 to November 2014, 107 patients with spontaneous pneumothorax were treated in our institution. Eighty-nine of these patients were analysed retrospectively. The inclusion criteria for thoracoscopic m-tent for spontaneous pneumothorax were multiple and widespread bullae, postoperative relapse and secondary spontaneous pneumothorax. The surgical procedures were usually performed through three ports. After bullectomy, an m-tent is made to strip the parietal pleura off the chest wall from about the level of the fourth or fifth rib to the apex, and two or three ligations are then applied to fix the pleural tent and lung parenchyma. Patients in whom an m-tent was not indicated underwent bullectomy plus coverage using absorbable materials. RESULTS Twenty-seven patients underwent bullectomy plus m-tent (m-tent group) and 62 underwent bullectomy plus coverage over a staple line using an absorbable material such as a polyglycolic acid sheet or nitrocellulose sheet (coverage group). No severe postoperative complications were observed in either group. The m-tent and coverage groups showed significant differences in operation time (129 vs 86 min, mean), haemorrhage (12.8 vs 7.2 ml), postoperative hospital stay (3.7 vs 2.9 days) and postoperative painkiller intake (8.6 vs 6.8 days). Recurrence was observed in 1 (3.7%) and 2 patients (3.2%), respectively. CONCLUSIONS The thoracoscopic m-tent procedure requires a longer operation, a longer hospital stay and greater painkiller intake. However, these differences are acceptable, and an m-tent should be considered as an option for pleural reinforcement in spontaneous pneumothorax, especially in patients who are complicated with severe pulmonary emphysema, widespread bullae or recurrent pneumothorax.

Abstract
Type 2 diabetes results from the failure of beta-cells to adequately compensate for insulin resistance. Although the reduction of beta-cell mass is because of increased cell death and/or inadequate replication or neogenesis, the mechanism underlying beta-cell mass reduction is not fully understood. Here, we clarify the role of insulin signaling pathway in the beta-cell apoptosis using insulin resistant model mice. Wild-type mice and those carrying a mutation in the insulin receptor (mIR) were fed either regular chow or a high-fat diet for 6 weeks and subsequently investigated for beta-cell apoptosis, endoplasmic reticulum stress, and oxidative stress. Insulin tolerance tests revealed that mIR mice fed a high-fat diet (mIRHF) had higher insulin resistance. Beta-cell apoptosis was increased 2-fold in the wild-type mice fed a high-fat diet (wHF) compared with control mice, whereas beta-cell apoptosis in mIRHF mice did not increase compared with that in mIR mice. The expression of endoplasmic reticulum stress markers in isolated islets did not differ between the groups. Staining of 8-hydroxy-2'-deoxyguanosine and 4-hydroxy-2-nonenal in islets of wHF mice significantly increased, but the staining in mIRHF mice was not different from that in control group. Gene expression of the antioxidant enzyme MnSOD was significantly higher in mIRHF mice than those in the other 3 groups. A mutation in the insulin receptor attenuated the oxidative stress and apoptosis in beta-cells even though high caloric nutrient was loaded. Our results suggest that reduced insulin signaling protects beta-cells thorough decline of oxidative stress.

Abstract
BACKGROUND The purpose of this study is to evaluate the prevalence and intensity and examine the risk factors of soil transmitted helminth (STH; i.e., roundworm [Ascaris lumbricoides], hookworms [Ancylostoma duodenale and Necator americanus], and whipworm [Trichuris trichiura]) infections in Nepal. METHODS Five hundred and ninety-four adults (256 men and 338 women) were selected via convenience sampling from five communities in Nepal. The Kato-Katz method was used to assess the prevalence and intensity of STH infection in this population. RESULTS Prevalence of STH infection ranged from 3.3% in Birendranagar in Chitwan, 3.5% in Kuleshor in Kathmandu, 11.7% in Kanyam in Ilam, 17.0% in Dhikurpokhari in Kaski and 51.4% in Khokana in Lalitpur District [corrected]. Multivariable regression analysis revealed that not using soap for hand-washing was significantly associated with the prevalence and infection intensity of roundworm, hookworms and whipworm. Similarly, not wearing sandals or shoes outside was significantly associated with the prevalence and infection intensity of roundworm and hookworms, but not with infection intensity of whipworm. Literacy, being underweight or overweight, anemia and occupation were not associated with prevalence and intensity of roundworm and hookworms infection, but there was an association between occupation and the prevalence of whipworm infection. CONCLUSION STH infection was associated with individual hygiene behavior, but not with nutritional status or socio-demographic characteristics. Health policy focusing on changing individual hygiene behaviors might be useful in addressing STH infection in Nepal.

Abstract
BACKGROUND Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) has an extremely poor prognosis. Direct hemoperfusion with a polymyxin B-immobilized fiber column (PMX-DHP) has been used to improve oxygenation for acute respiratory distress syndrome. The study aim was to retrospectively determine the predictive factors affecting the prognosis of AE of IPF treated with PMX-DHP. METHODS We studied patients suffering from AE of IPF, treated with PMX-DHP combined with high-dose corticosteroid therapy. Stored serum taken before and after PMX-DHP therapy was analyzed for 27 cytokines and chemokines. RESULTS Nineteen patients with AE of IPF were studied. The median survival time after diagnosis of AE was 22 days. Survival rates after diagnosis of AE were 47.4% at 30 days, 31.6% at 60 days, and 26.3% at 90 days. Serum levels of Interleukin (IL)-7, an anti-fibrotic cytokine, in survivors at day 30 following PMX-DHP therapy ('Survivors') significantly increased after the treatment, compared to serum levels of non-survivors at day 30 after the therapy ('Nonsurvivors'), which did not demonstrate a significant change. Serum levels of IL-1beta, interferon-y and chemokine ligand (CCL) 2 levels were not significantly altered in 'Survivors', but were significantly changed in 'Nonsurvivors.' Multivariate Cox proportional-hazards analysis showed that an increase in IL-7 levels after PMX-DHP therapy and treatment without intubation (other than invasive positive-pressure ventilation) were significantly better prognostic factors. CONCLUSION The results suggest that serum IL-7 may be a useful prognostic factor for patients with AE of IPF treated with PMX-DHP, possibly reflecting underlying anti-fibrotic mechanisms.

Abstract
A 70-year-old man visited the Department of Head and Neck Surgery with a chief complaint of dysphagia. A tumor was observed in the epiglottis and vocal cord, and was diagnosed as squamous cell carcinoma by biopsy. Computed tomography (CT) showed a tumor mainly in the vocal cord. CT scans revealed a tumor centered on the vocal cord, with bilateral cervical lymph node metastases and a well-circumscribed 20-mm tumor in the anterior mediastinum. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed uptake in the primary lesion, left cervical lymph nodes, and anterior mediastinal tumor, which suggested a lymph node metastasis but did not exclude thymoma. The patient underwent video-assisted thoracic surgery (VATS) resection of the anterior mediastinal tumor with total laryngectomy, total thyroidectomy, and bilateral cervical lymph node dissection. The final pathological diagnosis was laryngeal cancer (glottic cancer, pT4aN2M1, pStage IVC) with thymic metastasis (presenting as an anterior mediastinal tumor). Thymic metastasis of laryngeal cancer is rare, and appears difficult to preoperatively differentiate from other mediastinal tumors.

Abstract
BACKGROUND Signaling mediated by hepatocyte growth factor (HGF)/MET promotes multiple biological activities, including cell proliferation, motility, invasion, angiogenesis, and morphogenesis. Overexpression of HGF and MET and an increase of the MET gene copy number have recently been found in various cancers that had a poor outcome. Here we investigated the copy number of the MET gene and expression of MET and HGF in small pulmonary adenocarcinomas. METHODS Tumor tissues were obtained from 106 pulmonary small adenocarcinomas 2 cm or less in diameter. MET gene copy number, and the expression of MET and HGF, were analyzed using fluorescence in situ hybridization (FISH) and immunohistochemistry, respectively. RESULTS MET FISH-positive signals were observed in 11 (10.4%) of 106 cases. One case (0.9%) showed gene amplification and 10 (9.4%) exhibited high polysomy. High immunoreactivity for MET and HGF in tumor cells was found in 30 (28.3%) and 19 cases (17.9%), respectively. HGF was also expressed in stromal cells in 32 cases (30.2%). No cases of non-invasive adenocarcinoma (adenocarcinoma in situ, localized bronchioloalveolar carcinoma) showed MET FISH-positive signals or high expression of HGF in the tumor cells. Expression of both MET and stromal HGF was stronger in invasive than in non-invasive adenocarcinoma. MET FISH-positive signals and high immunoreactivity for MET and HGF in tumor cells were associated with factors indicative of poor prognosis such as pleural invasion, vascular invasion, lymphatic permeation, lymph node metastasis, and nuclear grading. Univariate and multivariate analyses that included these factors showed that all statuses except for MET and HGF immunoreactivity were significantly associated with an increased risk of death. However, multivariate analysis revealed no independent factors related to poor prognosis. CONCLUSION Our results suggest that abnormality of the HGF/MET pathway occurs during the course of progression from non-invasive to invasive pulmonary adenocarcinoma. An increased MET gene copy number is indicative of a poor outcome in patients with small pulmonary adenocarcinomas.

Abstract
Elastofibroma is a tumor that is localized mainly at the subscapular region. We report 2 cases of subscapular elastofibromas. Case 1, 75-year-old woman was seen at the hospital because of a left dorsal tumor. Computed tomography (CT) scan revealed the tumor of 6 cm in diameter in the inferior angle of left scapula. The patient underwent excision of the tumor. Case 2, 90-year-old man underwent excision a tumor of 5 cm in diameter in the inferior angle of right scapula simultaneously with the operation of right lung cancer. Histological examinations showed increased elastic fiber with elastica van Gieson staining. These specimens confirmed the diagnosis of elastofibroma There have been no signs of recurrence after surgery.
