4Device-associated infection rates, mortality, length of stay and bacterial resistance in intensive care units in Ecuador: International Nosocomial Infection Control Consortium's findings显示文摘AIM To report the results of the International Nosocomial Infection Control Consortium(INICC) study conducted in Quito, Ecuador.METHODS A device-associated healthcare-acquired infection(DAHAI) prospective surveillance study conducted from October 2013 to January 2015 in 2 adult intensive care units(ICUs) from 2 hospitals using the United States Centers for Disease Control/National Healthcare Safety Network(CDC/NHSN) definitions and INICC methods. RESULTS We followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection(CLABSI) rate was 6.5 per 1000 central line(CL)-days, the ventilator-associated pneumonia(VAP) rate was 44.3 per 1000 mechanical ventilator(MV)-days, and the catheterassociated urinary tract infection(CAUTI) rate was 5.7 per 1000 urinary catheter(UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9(CLABSI) and 5.3(CAUTI)] and higher than NHSN rates [0.8(CLABSI) and 1.3(CAUTI)]- although device use ratios for CL and UC were higher than INICC and CDC/NSHN's ratios. By contrast, despite the VAP rate was higher than INICC(16.5) and NHSN's rates(1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI. CONCLUSION DA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates.Estuardo Salgado Yepez Maria M Bovera Victor D Rosenthal Hugo A González Flores Leonardo Pazmino Francisco Valencia Nelly Alquinga Vanessa Ramirez Edgar Jara Miguel Lascano Veronica Delgado Cristian Cevallos Gasdali Santacruz Cristian Pelaéz Celso Zaruma Diego Barahona Pinto 2017World Journal of Biological Chemistry2017,8,1:23

8Primary colorectal lymphoma:An overview显示文摘Lymphomas represent common hematological malignancies with increasing incidence in recent years.The major site of extranodal non-Hodgkin lymphoma is the gastrointestinal tract.Involvement of the large intestine is rare in comparison to the stomach or small bowel.The disease appears later in life,predominantly in the male population.Complaints are nonspecific,requiring a high index of suspicion in order to establish the diagnosis.The treatment varies from chemotherapy alone to multimodal therapies combining surgery,chemotherapy and radiotherapy.The small number of patients with various histological subtypes and different stage at presentation results in unclear protocol for the treatment of primary colorectal lymphoma.The purpose of this paper is to review current data on primary lymphoma of the colon and rectum while analyzing reported case series and published material on the subject.Goran Z Stanojevic Milica D Nestorovic Branko R Brankovic Miroslav P Stojanovic Milan M Jovanovic Milan D Radojkovic 2011World Journal of Gastrointestinal Oncology2011,3,1:15
9A study of pulmonary embolism after abdominal surgery in patients undergoing prophylaxis显示文摘AIM:To determine risk factors for pulmonary embolism and estimate effects and benefits of prophylaxis.METHODS:We included 78 patients who died subsequently to a pulmonary embolism after major abdomi nal surgery from 1985 to 2003.A first,retrospective analysis involved 41 patients who underwent elective surgery between 1985 and 1990 without receiving any prophylaxis.In the prospectively evaluated subgroup,37 patients undergoing major surgery between 1991 and 2003 were enrolled:all of them had received a prophylaxis consisting in low-molecular weight heparin,given subcutaneously at a dose of 2850 IU AXa/0.3 mL(body weight < 50 kg) or 5700 IU AXa/0.6 mL(body weight ≥ 50 kg).RESULTS:A higher incidence of thromboembolism(43.9% and 46.34% in the two groups,respectively) was found in older patients(> 60 years).The incidence of pulmonary embolism after major abdominal surgery in patients who had received the prophylaxis was signifi cantly lower compared to the subjects with the same condition who had not received any prophylaxis(P < 0.001,OR = 2.825;95% CI,1.811-4.408).Furthermore,the incidence of pulmonary embolism after colorectal cancer surgery was signifi cantly higher compared to incidence of pulmonary embolism after other abdominal surgical procedures.Finally,the incidence of pulmonary embolism after colorectal cancer surgery among the patients who had received the prophylaxis(11/4316,0.26%) was significantly lower compared to subjects undergoing a surgical procedure for the same indication but without prophylaxis(10/1562,0.64%)(P < 0.05,OR = 2.522;95% CI,1.069-5.949).CONCLUSION:Prophylaxis with low molecular weight heparin is highly recommended during the preoperative period in patients with diagnosis of colorectal cancer due to high risk of pulmonary embolism after elective surgery.Mirko D Kerkez Dorde M ulafi Dragana D Mija Vitomir I Rankovi Nebja S Leki Dejan Z Stefanovi 2009World Journal of Gastroenterology2009,15,3:14

14Adenosquamous carcinoma of the pancreas: Molecular characterization of 23 patients along with a literature review显示文摘Adenosquamous carcinoma of the pancreas(ASCP)is a rare entity. Like adenocarcinoma of the pancreas,overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP.Molecular characterization revealed overexpression in MRP1(80%), MGMT(79%), TOP2A(75), RRM1(42%),TOPO1(42%), PTEN(45%), CMET(40%), and C-KIT(10%) among others. One hundred percent of samples tested were positive for KRAS mutations. This analysis shows heretofore unsuspected leads to be considered for treatments of this rare type of exocrine pancreas cancer. Molecular profiling may be appropriate to provide maximum information regarding the patient's tumor. Further work should be pursued to better characterize this disease.Erkut Borazanci Sherri Z Millis Ron Korn Haiyong Han Clifford J Whatcott Zoran Gatalica Michael T Barrett Derek Cridebring Daniel D Von Hoff 2015World Journal of Gastrointestinal Oncology2015,7,9:6

19High efficiency, high power 808nm laser array and stacked arrays optimized for elevated temperature operation显示文摘Operation of 808-nm laser diode pumping at elevated temperature is crucial to many applications. Reliable operation at high power is limited by high thermal load and low catastrophic optical mirror damage (COMD) threshold at elevated temperature range. We demonstrated high efficiency and high power operation at elevated temperature with high COMD power. These results were achieved through device design optimization such as growth conditions, doping profile, and materials composition of the quantum-well and other layers. Electrical-to-optical efficiency as high as 62% was obtained through lowered threshold current, lowered series resistance and increased slope efficiency. The performance of single broad-area laser diodes scales to that of high power single bars on water-cooled copper micro-channel heatsinks or conductively-cooled CS heatsinks. No reduction in bar performance or significant spectral broadening is seen when these micro-channel coolers are assembled into 6-bar and 18-bar CW stacks for the highest power levels.Crump P A Crum T R DeVito M Farmer J Grimshaw M Huang Z Igl S A Macomber S Thiagarajan P Wise D 2004光机电信息2004,21,6:4
20叶酸与甲酰四氢叶酸用于减少甲氨蝶呤治疗副作用(摘要)显示文摘1 背景 甲氨蝶呤用于治疗许多风湿病,其短期疗效已被证实。但毒性使不少患者不能从中受益,其中叶酸缺乏可增加其毒性。类风湿关节炎患者常有叶酸缺乏,经甲氨蝶呤治疗后叶酸储备就进一步减少。甲氨蝶呤的胃肠道和血液学副作用都与叶酸缺乏有关,可以预见,叶酸补充疗法将有助改善低剂量甲氨蝶呤治疗的副作用。对此,已有不少试验开展,并提出不同的副作用减少率。Ortiz Z SheaB Suarez Almazor M Moher D Wells G Tugwell P 姚如愚 2001循证医学2001,1,1:4
