| 1 | Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan显示文摘AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors. | Yutaka Suzuki Seryna Tamez Akihiko Murakami Akihiko Taira Akihiro Mizuhara Akira Horiuchi Chie Mihara Eiji Ako Hirohito Muramatsu Hitoshi Okano Hitoshi Suenaga Kazuaki Jomoto Junya Kobayashi Katsunari Takifuji Kazuhiro Akiyama Koh Tahara Koji Onishi Makoto Shimazaki Masami Matsumoto Masashi Ijima Masato Murakami Masato Nakahori Michiaki Kudo Michio Maruyama Mikako Takahashi Naohiro Washizawa Shigeru Onozawa Satoshi Goshi Satoyoshi Yamashita Shigeki Ono Shin Imazato Shinji Nishiwaki Shuichirou Kitahara Takao Endo Takao Iiri Takeshi Nagahama Takuto Hikichi Tatsuya Mikami Tetsuo Yamamoto Tetsushi Ogawa Tomoko Ogawa Tomoyuki Ohta Toshifumi Matsumoto Toshiroh Kura Tsutomu Kikuchi Tsuyoshi Iwase Tsuyotoshi Tsuji Yukio Nishiguchi Mitsuyoshi Urashima | 2010 | World Journal of Gastroenterology2010，16，40： | 4 |
| 2 | Simultaneous removal of dissolved organic matter and bromide from drinking water source by anion exchange resins for controlling disinfection by-products显示文摘Anion exchange resins(AERs) with different properties were evaluated for their ability to remove dissolved organic matter(DOM) and bromide, and to reduce disinfection by-product(DBP) formation potentials of water collected from a eutrophic surface water source in Japan. DOM and bromide were simultaneously removed by all selected AERs in batch adsorption experiments. A polyacrylic magnetic ion exchange resin(MIEX) showed faster dissolved organic carbon(DOC) removal than other AERs because it had the smallest resin bead size. Aromatic DOM fractions with molecular weight larger than 1600 Da and fluorescent organic fractions of fulvic acid- and humic acid-like compounds were efficiently removed by all AERs. Polystyrene AERs were more effective in bromide removal than polyacrylic AERs. This result implied that the properties of AERs, i.e. material and resin size, influenced not only DOM removal but also bromide removal efficiency. MIEX showed significant chlorinated DBP removal because it had the highest DOC removal within 30 min, whereas polystyrene AERs efficiently removed brominated DBPs, especially brominated trihalomethane species. The results suggested that, depending on source water DOM and bromide concentration,selecting a suitable AER is a key factor in effective control of chlorinated and brominated DBPs in drinking water. | Athit Phetrak Jenyuk Lohwacharin Hiroshi Sakai Michio Murakami Kumiko Oguma Satoshi Takizawa | 2014 | Journal of Environmental Sciences2014，26，6： | 2 |

| 15 | Right colon cancer presenting as hemorrhagic shock显示文摘A 67-year-old man visited our hospital with a history of continuous hematochezia leading to hemorrhagic shock.An abdominal computed tomography scan re-vealed a large mass in the ascending colon invading the duodenum and pancreatic head as well as extra-vasation of blood from the gastroduodenal artery(GDA) into the colon.Colonoscopy revealed an irregular ulcerative lesion and stenosis in the ascending colon.Therefore,right hemicolectomy combined with pylorus-preser ving pancreaticoduodenectomy was performed.Histologically,the tumor was classified as a moderately differentiated adenocarcinoma.Moreover,cancer cells were mainly located in the colon but had also invaded the duode-num and pancreas and involved the GDA.Immunohistochemically,the tumor cells were positive for cytokeratin(CK)20 and carcinoembryonic antigen(CEA)but not forCK7 and carbohydrate antigen(CA)19-9.The patient died 23 d after the surgery because he had another episode of arterial bleeding from the anastomosis site.Although En bloc resection of the tumor with pancreatico duodenectomy and colectomy performed for locally advanced colon cancer can ensure long-term survival,patients undergoing these procedures should be carefully monitored,particularly when the tumor involves the main artery. | Tomoyuki Iwata Kazuo Konishi Takahisa Yamazaki Katsuya Kitamura Atsushi Katagiri Takashi Muramoto Yutaro Kubota Yuichiro Yano Yoshiya Kobayashi Toshiko Yamochi Nobuyuki Ohike Masahiko Murakami Takehiko Gokan Nozomi Yoshikawa Michio Imawari | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，1： | 0 |
