Chertsey Outcome Score for Trauma： Development and validation of a new unifying patient reported outcome measure for orthopaedic trauma

引用

Chinese Journal of Traumatology 2017年第6期20卷 329-332页

作者： Efthymios Iliopoulos sujit Agarwal Arshad Khaleel The Rowley Bristow Unit Ashford and St Peter's Hospitals NHS Foundation Trust Chertsey United Kingdom

Purpose： Lately there is an increasing tendency of using Patient Reported Outcome Measures （PROMs） as a final indicator of the outcome of many surgical treatments in orthopaedics and in other medical specialties. Currently there are many outcome scores in orthopaedics and most of them are site specific. In the contrary there is a lack of trauma specific outcome scores. Methods： We have designed a new PROM especially for orthopaedic trauma patients, in order to measure in what extent the patients manage to return to their pre-injury state. This score uses as baseline the preinjury status of the patient and has the aim to determine the percentage of rehabilitation after treatment for any injury. Results： A total of 60 Chertsey Outcome Score for Trauma （COST） questionnaires were gathered in our outpatients department. The participants were 57% male （aged 46.81 years ± 18.5 years） and the questionnaires collected at mean 10 months post-injury. A Cronbach＇s Alpha value of 0.89 was identified for the whole construct. The three dimensions of the scale had good internal consistency as well （Cronbach＇s Alpha test values 0.74, 0.84 and 0.81 for symptoms, function and mental status respectively）. Strong/moderate correlation （Spearman＇s Rho test 0.43-0.65） was observed between the respective physical/mental dimensions of the COST and SF-12v2 questionnaires. Conclusion： There is a need among the orthopaedic trauma society for a specific PROM of trauma. COST is a useful and easy to use tool for every trauma surgeon.

引用

World Journal of Gastroenterology 2007年第27期13卷 3730-3733页

作者： Prasun Bhattacharya Partha Kumar Chandra Sibnarayan Datta Arup Banerjee Subhashish Chakraborty Krishnan Rajendran Subir Kumar Basu sujit Kumar Bhattacharya Runu Chakravarty Institute of Blood Transfusion Medicine and Immunohematology Kolkata India ICMR Virus Unit Kolkata India National Institute of Cholera and Enteric Diseases Kolkata India

AIM: To evaluate the prevalence of markers of hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immunodeficiency virus (HIV) among blood donors in Kolkata, Eastern India for two consecutive years and to conduct a pilot study to explore the presence of HBV DNA among hepatitis B surface antigen (HBsAg) negative but anti-HBc positive blood donors. METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations.

Hybrid organolead halide perovskites have attracted tremendous attention due to their recent success as high efficiency solar cell materials and their fascinating material properties uniquely suitable for optoelectronic devices. However, the poor ambient and operational stability as well as the concern of lead toxicity greatly hamper their practical utilization. In this work, crystalline, all-inorganic and lead-free Cs_(3)Sb_(2)I_(9) perovskite microplates are successfully synthesized by a two-step chemical vapor deposition method. As compared with other typical lead-free perovskite materials, the Cs_(3)Sb_(2)I_(9) microplates demonstrate excellent optoelectronic properties, including substantial enhancements in the Stokes shift, exciton binding energy and electron-phonon coupling. Simple photoconductive devices fabricated using these microplates exhibit an ultra-fast response with the rise and decay time constants down to 96 and 58 µs, respectively. This respectable photoconductor performance can be regarded as a record among all the lead-free perovskite materials. Importantly, these photodetectors show superior thermal stability in a wide temperature range, capable to function reversibly between 80 and 380 K, indicating their robustness to operate under both low and high temperatures. All these results evidently suggest the technological potential of inorganic lead-free Cs_(3)Sb_(2)I_(9) perovskite microplates for next-generation high-performance optoelectronic devices.

American Journal of Computational Mathematics 2013年第1期3卷 80-85页

作者： sujit Handibag B. D. Karande Department of Mathematics Maharashtra Udaygiri Mahavidyalaya Udgir India Department of Mathematics Mahatma Basweshwar Mahavidyalaya Latur India

In this paper, we develop a method to calculate numerical and approximate solution of some fifth-order Korteweg-de Vries equations with initial condition with the help of Laplace Decomposition Method (LDM). The technique is based on the application of Laplace transform to some fifth-order Kdv equations. The nonlinear term can easily be handled with the help of Adomian polynomials. We illustrate this technique with the help of four examples and results of the present technique have closed agreement with approximate solutions obtained with the help of (LDM).

The dietary phytochemicals curcumin （CUR） and sulforaphane （SFN） have shown remarkable cancer chemopreventive effects in many model systems. This study was designed to investigate the induction of Nrf2-mediated antioxidant enzymes by combining doses of CUR and SFN and the effect of their combination on the Nrf2-ARE （antioxidant response element） response in HepG2-C8 cells. We hypothesized that the combination of the polyphenol CUR and the isothiocyanate SFN could enhance the induction of AREs and Nrf2-target enzymes. HepG2-C8 cells were treated with a combination of low doses of CUR, SFN or both. The induction of Nrf2-mediated antioxidant and phase II detoxifying enzymes-heme oxygenase-1 （HO-I） and UDP-glucuronosyltransferase-1A （UGT1A）-was measured by real-time RT-PCR and western blotting. ARE-luciferase activity was also quantified. Low doses of CUR （10 ~tM） and SFN （12.5 ~tM） significantly induced the expression of HO-1 and UGT 1 A1 proteins. Through the use of chemical inhibitors of mRNA and protein synthesis, the combination of CUR and SFN was shown to affect the transcriptional regulation of both HO-1 and UGT1A1. Additionally, the combination of CUR and SFN synergistically induced the expression of Nrf2- and ARE-luciferase activity in HepG2-C8 cells. Thus, CUR and SFN at low concentrations augment therapeutic effects in HepG2-C8 cells. The enhanced ARE-luciferase activity of combined CUR and SFN treatment could partly explain the significant induction of the Nrf2-target enzymes HO-1 and UGT1A1. Taken together, our results suggest that combining low doses of CUR and SNF could be a promising strategy for cancer chemoprevention in humans.
