1Diagnosis of Crohn's disease in India where tuberculosis is widely prevalent显示文摘AIM:To define the parameters that positively predict diagnosis of Crohn's disease (CD) and differentiate it from gastrointestinal tuberculosis (GITB). METHODS:This prospective study over 3 years was carried out in the consecutive Indian patients with definite diagnosis of CD and equal numbers of patients with definite diagnosis of GITB. Demographic, clinical, laboratory, morphological and histological features were noted in all the patients. Serological tests such as p-ANCA, c-ANCA, IgA ASCA and IgG ASCA, were performed. Endoscopic biopsy and/or surgical tissue specimens were subjected to smear and culture for acid-fast bacilli (AFB) and tissue polymerase chain reaction for tuberculosis (TB PCR). Diagnosis of CD and GITB was based on the standard criteria. Data were analyzed using univariate Chi-square test and multiple logistic regression (MLR). RESULTS:The study is comprised of 26 patients with CD (age 36.6 ± 8.6 year, male:female, 16:10) and 26 patients with GITB (age 37.2 ± 9.6 year, male:female, 15:11). The following clinical variables between the two groups (CD vs TB) were significant in univariate analysis:duration of symptoms (58.1 ± 9.8 vs 7.2 ± 3.4 mo), diarrhoea (69.2% vs 34.6%), bleeding per rectum (30.7% vs 3.8%), fever (23.1% vs 69.2%), ascites (7.7% vs 34.6%) and extra-intestinal manifestations of inflammatory bowel disease (61.5% vs 23.1%). Of these, all except ascites and extra-colonic manifestations were found statistically significant by MLR. Accuracy of predicting CD was 84.62% based on the fever, bleeding P/R, diarrhoea and duration of symptoms while it was 63.4% when histology was reported as inflammatory bowel disease and 42.3% when there was recurrence of disease after surgery. Accuracy of predicting GITB was 73.1% when there was co-existing pulmonary lesions and/or abdominal lymphadenopathy;75% when tuberculosis was reported in histology;63.4% when granuloma was found in histology;82.6% when TB PCR was positive;and 61.5% when smear and/ or culture was positive for AFB. Serological test was not useful in differentiation of CD from GITB. Positivity rates for CD and GITB were:p-ANCA-3.8% and 3.8%, c-ANCA-3.8% and 0%, IgA ASCA-38.4% and 23.1%, and IgG ASCA-38.4% and 42.3%, respectively. CONCLUSION:Simple clinical parameters like fever, bleeding P/R, diarrhoea and duration of symptoms have the highest accuracy in differentiating CD from GITB.Deepak N Amarapurkar Nikhil D Patel Priyamvada S Rane 2008World Journal of Gastroenterology2008,14,5:24
2动脉粥样硬化血栓形成门诊患者1年内心血管事件的发生率显示文摘背景:目前,有关社区中动脉粥样硬化血栓形成稳定患者心血管(cardiovascular,CV)事件发生率的资料比较少,既往也无国际性队列研究对冠状动脉病(coronary artery disease,CAD)、脑血管病(cerebrovascular disease,CVD)、外周动脉病(peripheral arterial disease,PAD)确诊患者以及此类疾病高危患者不同事件的发生率进行评估。 目的:在患有动脉疾病的门诊患者或存在多个动脉粥样硬化血栓形成危险因素的门诊患者中确定当今世界1年内CV事件的发生率。 设计、地点及参试者:“减少动脉粥样硬化血栓形成维系健康(Reduction of Artherotllrombosis for Continued Health,REACH)”注册研究是一项国际前瞻性队列研究。研究人员于2003—2004年从44个国家、5587名医生入选68236例已确诊的动脉粥样硬化性血管病患者(CAD、PAD、CVD;n=55814)以及至少存在3个动脉粥样硬化血栓形成危险因素的患者(n=12422)。 主要观测指标:CV死亡、心肌梗死(myocardial infarction,MI)及卒中的发生率。结果:截至2006年7月,共有95.22%的患者(n=64977)提供了1年内的结局。心血管死亡、MI及卒中的总体发生率为4.24%;动脉粥样硬化性血管病患者为4.69%,仅存在多个危险因素的患者为2.15%。CAD、CVD及PAD患者CV死亡、MI及卒中的总体发生率分别为4.52%、6.47%和5.35%。CAD、CVD及PAD患者发生终点事件(即CV死亡、MI、卒中)以及因动脉粥样硬化血栓形成事件入院的几率分别为15.20%、14.53%和21.14%。上述事件发生率随症状性动脉疾病病变部位数量的增加而增加,仅存在危险因素的患者为5.31%,有1处症状性动脉疾病的患者为12.58%,有2处症状性动脉疾病的患者为21.14%,有3处症状性动脉疾病的患者为26.27%(趋势P〈0.001)。 结论:在这项当代大型国际研究中,患有动脉粥样硬化性血管病的门诊患者以及有动脉粥样硬化血栓形成危险的门诊患者CV事件的年发生率相对较高。存在多部位病变者CV事件的1年发生率升高。Gabriel Steg Deepak L.

3Changing spectrum of Budd-Chiari syndrome in India with special reference to non-surgical treatment显示文摘AIM: To evaluate patterns of obstruction, etiological spectrum and non-surgical treatment in patients with Budd-Chiari syndrome in India.METHODS: Forty-nine consecutive cases of Budd-Chiari syndrome (BCS) were prospectively evaluated. All patients with refractory ascites or deteriorating liver function were, depending on morphology of inferior vena cava (IVC) and/or hepatic vein (HV) obstruction, triaged for radiological intervention, in addition to anticoagulation therapy. Asymptomatic patients, patients with diuretic-responsive ascites and stable liver function, and patients unwilling for surgical intervention were treated symptomatically with anticoagulation.RESULTS: Mean duration of symptoms was 41.5 ± 11.2 (range = 1-240) mo. HV thrombosis (HVT) was present in 29 (59.1%), IVC thrombosis in eight (16.3%), membranous obstruction of IVC in two (4%) and both IVC-HV thrombosis in 10 (20.4%) cases. Of 35 cases tested for hypercoagulability, 27 (77.1%) were positive for one or more hypercoagulable states. Radiological intervention was technically successful in 37/38 (97.3%): IVC stenting in seven (18.9%), IVC balloon angioplasty in two (5.4%), combined IVC-HV stenting in two (5.4%), HV stenting in 11 (29.7%), transjugular intrahepatic portosystemic shunt (TIPS) in 13 (35.1%) and combined TIPS-IVC stenting in two (5.4%). Complications encountered in follow-up: death in five, re-stenosis of the stent in five (17.1%), hepatic encephalopathy in two and hepatocellular carcinoma in one patient. Of nine patients treated medically, two showed complete resolution of HVT.CONCLUSION: In our series, HVT was the predominant cause of BCS. In the last five years with the availability of sophisticated tests for hypercoagulability, etiologies weredefined in 85.7% of cases. Non-surgical management was successful in most cases.Deepak N Amarapurkar Sundeep J Punamiya Nikhil D Patel 2008World Journal of Gastroenterology2008,14,2:9
4Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets 2015Photonics Research2015,3,5:7
5Outcomes of Medicare beneficiaries hospitalised with transient ischaemic attack and stratification using the ABCD^(2) score显示文摘Background Long-term outcomes for Medicare beneficiaries hospitalised with transient ischaemic attack(TIA)and role of ABCD^(2) score in identifying high-risk individuals are not studied.Methods We identified 40825 Medicare beneficiaries hospitalised from 2011 to 2014 for a TIA to a Get With The Guidelines(GWTG)-Stroke hospital and classified them using ABCD^(2)s of mortality and rehospitalisation(all-cause,ischaemic stroke,haemorrhagic stroke,myocardial infarction,and gastrointestinal and intracranial haemorrhage)for high-risk versus low-risk groups adjusted for patient and hospital characteristics.Results Of the 40825 patients,35118(86%)were high risk(ABCD^(2)≥4)and 5707(14%)were low risk(ABCD^(2)=0-3).Overall rate of mortality during 1-year follow-up after hospital discharge for the index TIA was 11.7%,44.3% were rehospitalised for any reason and 3.6%were readmitted due to stroke.Patients with ABCD^(2) score≥4 had higher mortality at 1 year than not(adjusted HR 1.18,95%CI 1.07 to 1.30).Adjusted risks for ischaemic stroke,all-cause readmission and mortality/all-cause readmission at 1 year were also significantly higher for patients with ABCD^(2) score≥4 vs 0-3.In contrast,haemorrhagic stroke,myocardial infarction,gastrointestinal bleeding and intracranial haemorrhage risk were not significantly different by ABCD^(2) score.Conclusions This study validates the use of ABCD^(2) score for long-term risk assessment after TIA in patients aged 65 years and older.Attentive efforts for community-based follow-up care after TIA are needed for ongoing prevention in Medicare beneficiaries who were hospitalised for TIA.Shreyansh Shah Li Liang Durgesh Bhandary Saga Johansson Eric E Smith Deepak L Bhatt Gregg C Fonarow Naeem D Khan Eric Peterson Janet Prvu Bettger 2021Stroke & Vascular Neurology2021,6,2:3
