| 9 | Gas selectivity of SILAR grown CdS nano-bulk junction显示文摘Nano-particles of cadmium sulphide were deposited on cleaned copper substrate by an automated sequential ionic layer adsorption reaction(SILAR)system.The grown nano-bulk junction exhibits Schottky diode behavior.The response of the nano-bulk junction was investigated under oxygen and hydrogen atmospheric conditions.The gas response ratio was found to be 198%for Oxygen and 34%for Hydrogen at room temperature.An increase in the operating temperature of the nano-bulk junction resulted in a decrease in their gas response ratio.A logarithmic dependence on the oxygen partial pressure to the junction response was observed,indicating a Temkin isothermal behavior.Work function measurements using a Kelvin probe demonstrate that the exposure to an oxygen atmosphere fails to effectively separate the charges due to the built-in electric field at the interface.Based on the benefits like simple structure,ease of fabrication and response ratio the studied device is a promising candidate for gas detection applications. | R.Jayakrishnan Varun G Nair Akhil M Anand Meera Venugopal | 2018 | Journal of Semiconductors2018，39，3： | 0 |
| 10 | Intraoperative endoscopic retrograde cholangiopancreatography for traumatic pancreatic ductal injuries:Two case reports显示文摘BACKGROUND In order to successfully manage traumatic pancreatic duct(PD)leaks,early diagnosis and operative management is paramount in reducing morbidity and mortality.In the acute setting,endoscopic retrograde cholangiopancreatography(ERCP)can be a useful,adjunctive modality during exploratory laparotomy.ERCP with sphincterotomy and stent placement improves preferential drainage in the setting of injury,allowing the pancreatic leak to properly heal.However,data in this acute setting is limited.CASE SUMMARY In this case series,a 27-year-old male and 16-year-old female presented with PD leaks secondary to a gunshot wound and blunt abdominal trauma,respectively.Both underwent intraoperative ERCP within an average of 5.9 h from time of presentation.A sphincterotomy and plastic pancreatic stent placement was performed with a 100%technical and clinical success.There were no associated immediate or long-term complications.Following discharge,both patients underwent repeat ERCP for stent removal with resolution of ductal injury.CONCLUSION These experiences further demonstrated that widespread adaption and optimal timing of ERCP may improve outcomes in trauma centers. | Andrew Canakis Varun Kesar Caleb Hudspath Raymond E Kim Thomas M Scalea Peter Darwin | 2022 | World Journal of Gastrointestinal Endoscopy2022，14，5： | 0 |
| 11 | Reducing unnecessary crossmatching for hip fracture patients by accounting for preoperative hemoglobin concentration显示文摘BACKGROUND Maximum surgical blood order schedules were designed to eliminate unnecessary preoperative crossmatching prior to surgery in order to conserve blood bank resources.Most protocols recommend type and cross of 2 red blood cell(RBC)units for patients undergoing surgery for treatment of hip fracture.Preoperative hemoglobin has been identified as the strongest predictor of inpatient transfusion,but current maximum surgical blood order schedules do not consider preoperative hemoglobin values to determine the number of RBC units to prepare prior to surgery.AIM To determine the preoperative hemoglobin level resulting in the optimal 2:1 crossmatch-to-transfusion(C:T)ratio in hip fracture surgery patients.METHODS In 2015 a patient blood management(PBM)program was implemented at our institution mandating a single unit-per-occurrence transfusion policy and a restrictive transfusion threshold of<7 g/dL hemoglobin in asymptomatic patients and<8 g/dL in those with refractory symptomatic anemia or history of coronary artery disease.We identified all hip fracture patients between 2013 and 2017 and compared the preoperative hemoglobin which would predict a 2:1 C:T ratio in the pre PBM and post PBM cohorts.Prediction profiling and sensitivity analysis were performed with statistical significance set at P<0.05.RESULTS Four hundred and ninety-eight patients who underwent hip fracture surgery between 2013 and 2017 were identified,291 in the post PBM cohort.Transfusion requirements in the post PBM cohort were lower(51%vs 33%,P<0.0001)than in the pre PBM cohort.The mean RBC units transfused per patient was 1.15 in the pre PBM cohort,compared to 0.66 in the post PBM cohort(P<0.001).The 2:1 C:T ratio(inpatient transfusion probability of 50%)was predicted by a preoperative hemoglobin of 12.3 g/dL[area under the curve(AUC)0.78(95%confidence interval(CI),0.72-0.83),Sensitivity 0.66]in the pre PBM cohort and 10.7 g/dL[AUC 0.78(95%CI,0.73-0.83),Sensitivity 0.88]in the post PBM cohort.A 50%probability of requiring>1 RBC unit was predicted by 11.2g/dL[AUC 0.80(95%CI,0.74-0.85),Sensitivity 0.87]in the pre PBM cohort and 8.7g/dL[AUC 0.78(95%CI,0.73-0.83),Sensitivity 0.84]in the post-PBM cohort.CONCLUSION The hip fracture maximum surgical blood order schedule should consider preoperative hemoglobin in determining the number of units to type and cross prior to surgery. | Raj M Amin Varun Puvanesarajah Yash P Chaudhry Matthew J Best Sandesh S Rao Steven M Frank Erik A Hasenboehler | 2021 | World Journal of Orthopedics2021，12，5： | 0 |
