Anastomotic leakage after esophagectomy is associated with prolonged hospitalization and increased medical cost. Additionally, it sometimes leads to a fatal condition and impaired postoperative quality of life. During the process of wound healing, β-hydroxy-β-methylbutyrate (HMB) is important for collagen biosynthesis. An open-label prospective intervention trial has been designed to evaluate the treatment effect of an enteral nutrient containing HMB with arginine and glutamine (Abound, Abbott Japan Co., Ltd.) for leakage at the anastomotic site after esophagectomy. Patients in whom leakage at the anastomotic site developed within 14 days after esophagectomy are eligible and Abound (24 g) is administered for 14 days through an enteral feeding tube. The target sample size is 10. The primary endpoint is duration between diagnosis and cure of leakage. Surgical procedure, safety, length of fasting, drainage placement and hospital stay, and nutritional status are determined as secondary endpoints. A historical control consisting of 20 patients who had leakage at the anastomotic site after esophagectomy between 2005 and 2018 at Nagoya University Hospital is compared with enrolled patients.Micro-computed tomography (µCT) provides extremely high-resolution images of samples and can be employed as a non-destructive inspection tool. Using µCT, we can obtain images comparable with microscopic images. In this work, we have attempted to take high-resolution images of the human lung using µCT. Compared to clinical high-resolution computed tomography (HRCT) images of living body (in-vivo imaging), we can obtain extremely high-resolution images by µCT of ex-vivo tissues (resected lungs) as three-dimensional data. The purpose of this study was to distinguish between areas of normal lung and lung cancer by µCT images in order to study the feasibility of cancer diagnosis using this novel radiological image modality. Ten resected human lungs containing primary cancer were fixed by Heitzman's methods to obtain high-resolution µCT images. After fixation of the lung, images of the specimens were taken by µCT between January 2016 and November 2017. The imaging conditions were tube voltage 90 kV and tube current Further detailed investigations with regard to µCT are needed to make comparable histological diagnoses using µCT images with conventional microscopic methods of pathological diagnoses.Local injection of methotrexate (MTX) has been widely used for caesarean scar pregnancy (CSP), but the optimal candidate remains undetermined. The aim of this study is to determine the risk factors associated with treatment failure among patients who received a single dose of local MTX. This is a retrospective cohort study. Clinical information was compared between treatment success vs. failure groups. Risk factors related to treatment failure were also investigated with multivariate analysis. Of 47 patients diagnosed with CSP, 30 received local MTX injection. The initial serum ß- human chorionic gonadotropin (hCG) level in the failure group was significantly higher than in the success group (p = 0.048), and the cut-off value was 47,000 mIU/ml. The rate of type 2 position of the gestational sac in the failure group was significantly higher than in the treatment success group (p = 0.031). A high initial serum ß-hCG level (≥ 47,000 mIU/ml) was identified as the independent risk factor for treatment failure (adjusted odds ratio = 21.9; 95% confidence interval = 1.3-383.1). Type 2 gestational sac position and a higher level of ß-hCG at diagnosis appear to be associated with poor outcomes after local injection of a single dose of MTX.The Japanese version of the EuroQol 5 dimension, 5 level version (EQ-5D-5L) can now be used to quantitatively evaluate the health-related quality of life (QoL) in Japan. Locomotive syndrome (LS) is a concept advocated in Japan to describe a condition requiring care for musculoskeletal disorders. However, no detailed study on the relationship between this index and LS in Japanese health checkup has been reported. [https://www.selleckchem.com/products/envonalkib.html Envonalkib mw] We aimed to evaluate the relationship between the Japanese version of the EQ-5D-5L and LS. We enrolled 477 participants who were undergoing health checkups in Japan. All participants were administered the 25-question Geriatric Locomotive Functional Scale for the diagnosis of LS and the Japanese version of the EQ-5D-5L. We performed statistical analysis to compare the non-LS and LS patients; moreover, the risk factors and cut-off values were calculated and verified. The Japanese version of the EQ-5D-5L index was significantly lower in patients with LS than in non-LS patients and was significantly related to LS in logistic regression analysis. In subgroup analysis targeting the five dimensions of the EQ-5D-5L, it was seen that mobility, pain/discomfort, and self-care were significantly involved in LS. The cut-off value of the EQ-5D-5L index for LS was 0.875. The Japanese version of the EQ-5D-5L index was significantly related to LS in Japan. This index will be a useful tool that can easily measure health-related quality of life in middle-aged and elderly Japanese people. Future studies should investigate the relationship of not only LS but also various diseases with the Japanese version of the EuroQol 5 dimension, 5 level version.Commercial bone substitutes that are widely used for bone augmentation for dental implants are predisposing factors in the development of osteonecrosis of the jaw (ONJ), overlooking this situation may lead to serious problems. Most of these materials are supplied as inorganic porous granules of calcium phosphate, which have characteristics that exceed the bone resorption ability of normal osteoclasts; therefore, they can be equally regarded as existing antiresorptive necrotic bony granules in the body, i.e., micro-ONJs. In addition, because dental implants directly contact the surrounding bone without the periodontium with immunoprotective functions, the mucosal penetration of the dental implant itself predisposes the underlying bone to the risk of infection, latent osteomyelitis, and ONJ. Therefore, the remaining porous granules surrounding the dental implant pose an additional iatrogenic risk, even though the tissue may appear superficially healthy. In an aging society, an individual who was systemically healthy at the time of implantation with bone augmentation could develop osteoporosis or cancer bone metastasis later in life.
