th e m100a 02 performance specification for new equipment purchases ct simulators and pet ct
Medical Physics, 2007Co-Authors: S MuticAbstract:Imaging equipment for radiation therapy (RT) has undergone significant changes during the past decade. Historically, imaging equipment has been designed almost exclusively for diagnostic radiology. Computed tomography(CT) and positron emission tomography(PET)scanners did not have any features which were specifically indented for imaging of RT patients. These scanners were used for radiationimaging often with modifications and largely were not suited well for the task. Today, the situation is different and all major scanner manufacturers offer devices which are designed specifically for RT imaging or which have features designed for RT. This paradigm change in how scanner manufacturers view RT imaging needs has resulted in significant increase in imaging equipment choices available to RT Departments. The change in scanner manufacturer approach towards RT is mainly driven by the increased need for CT and multimodality imaging(PET, MR, SPECT) in RT. The vast majority of radiationoncology Departments have a CTscanner, some have more than one, and many have PETCTscanners. The scanners found in radiationoncology are also no longer predominantly low end models but more commonly state of the art scanners capable of diagnostic quality imaging. For CTscanners, there are several gantry aperture sizes available with varying number of detector configurations. All manufacturers offer solutions for respiratory correlated imaging. Similarly, PET/CT scanners are indented to be used for RT treatment planningimaging and there are multiple options available on the market for this equipment as well. Understanding features of CT and PET/CT scanners that are available for RT imaging and selecting the scanner which best suits the needs and workflow of an Individual Department can significantly affect treatment planning and radiation delivery process. This presentation is designed to address features of CT and PET/CT scanners which are important for RT imaging and which are commercially available. The presentation will also address typical needs of Individual radiationoncology facilities and how modern CT and PET/CT scanners are meeting these needs. Educational Objectives: 1. Describe features available on commercial CTscanner (simulators). 2. Describe features available on commercial PET/CT scanners (simulators). 3. Describe how available CT and PET/CT scanner features can meet the needs of modern radiationoncology practice.

antimicrobial stewardship of chinese ministry of health reduces multidrug resistant organism isolates in critically ill patients a pre post study from a single center
BMC Infectious Diseases, 2016Co-Authors: Jianfeng Xie, Yi Yang, Fengmei Guo, Zhiwei Gao, Hua Shao, Yingzi Huang, Congshan Yang, Haibo QiuAbstract:China’s Ministry of Health (MOH) has established a policy about the antimicrobial stewardship. To date, the effects of this policy on multidrug-resistant organism (MDRO) in critically ill patients are unknown. A pre-post study was conducted on intensive care unit (ICU) patients from June 2010 to May 2011 and from June 2012 to May 2013. Bacterial cultures were conducted at ICU admission and discharge. In June 2011, our hospital started to administer the antimicrobial stewardship program of Chinese MOH. We collected the data on antimicrobial consumption during the 3-year period in all hospital and Individual Department every month, and analyzed the correlation between the proportion of critically patients colonized or infected with MDRO and antimicrobial consumption. A total of 978 patients were involved in the present study. With the intervention, the monthly mean Defined Daily Dose (DDD) per 100 occupied bed-days throughout the hospital decreased from 96 ± 7 to 65 ± 6 (p < 0.001), and the proportion of patients colonized or infected with MDRO decreased from 36 to 13% at the time of ICU admission and declined from 48 to 29% at the time of ICU discharge (both p < 0.001). There was a significant positive relationship between the proportion of all critically ill patients colonized or infected with MDRO at ICU admission and the DDD of the entire hospital (R2 = 0.7858, p < 0.001). The antimicrobial stewardship program of Chinese MOH reduced the consumption of antibiotics. Moreover, the proportion of patients colonized or infected with MDRO decreased along with reduced consumption of antibiotics.

prevalence distribution and risk of sessile serrated adenomas polyps at a center with a high adenoma detection rate and experienced pathologists
Endoscopy, 2016Co-Authors: Joep E G Ijspeert, Koos De Wit, Manon Van Der Vlugt, Barbara A J Bastiaansen, Paul Fockens, Evelien DekkerAbstract:Background and study aims: Sessile serrated adenomas/polyps (SSA/Ps) are the precursors of 15 % – 30 % of colorectal cancers (CRC). We aimed to determine the prevalence and distribution of SSA/Ps and to evaluate the association between SSA/Ps and the risk of synchronous advanced neoplasia at a high quality colonoscopy center. Methods: Data from all colonoscopies performed within one dedicated colonoscopy center between 2011 and 2015 were prospectively retrieved using an automated reporting system. All lesions were assessed by an experienced gastrointestinal pathologist. Multiple logistic regression was used to evaluate influence of age, gender, and colonoscopy indication on prevalence of SSA/Ps, and to assess the association between SSA/Ps and synchronous advanced neoplasia. Results: In total 4251 histologically confirmed polyps were resected in 3364 patients; 399 polyps were SSA/Ps (9.4 %). The prevalence of SSA/Ps was 8.2 % overall, increasing to 9.0 % for Individuals older than 50 years. SSA/P detection rate varied between 2.5 % and 13.6 % among endoscopists. Increased SSA/P prevalence was associated with colonoscopy indications “familial CRC risk” (odds ratio [OR] 1.52, 95 % confidence interval [95 %CI] 1.05 – 2.22; P = 0.03) and “surveillance” (OR 1.73, 95 %CI 1.20 – 2.49; P Conclusion: SSA/Ps are more common than previously reported and are associated with the presence of synchronous advanced neoplasia. Endoscopists should be assiduous in identifying SSA/Ps in daily practice and should carefully look for synchronous advanced neoplasia when an SSA/P has been recognized. Results from this study can guide detection standards in general colonoscopy practice adapted to the type of patient that may predominate in an Individual Department.

differences between the chinese and western cultures in perspective of colony Department and Individual Department
Journal of Inner Mongolia Normal University, 2001Co-Authors: Yang ShengAbstract:The intirety of the "colony Department" and the Individualism of the "Individual Department" are the basic menifestations of the differnces in the Chinese and Western cultural values. With the social colony as its values' own Department, the Chinese traditional culture has produced an order of values of the society's own Department. On the other hand, as its ideological base , Individualism embodies the essense of the western values. In modern times, with the increasing exchange betwen China and the western countries, there has arisen a tendency for the two entirely different orders of values to blend with each other through comparing with each other and learning from eacher . In perspective of cultural traditions, this paper explores the course of development of entirety in China and of Individualism in western countries, and analises the strong points and weak points of the two and the tendency towards blending.
