| 1 | Prognostic significance of red blood cell distribution width in gastrointestinal disorders显示文摘The red blood cell distribution width(RDW) is a routinely measured and automatically reported blood parameter,which reflects the degree of anisocytosis. Recently,the baseline RDW was found to have clinical significance for assessing clinical outcome and severity of various pathological conditions including cardiovascular diseases,sepsis,cancers,leukemia,renal dysfunction and respiratory diseases. A myriad of factors,most of which ill-defined,have an impact on the red cell population dynamics(i.e.,production,maturation and turnover). A delay in the red blood cell clearance in pathological conditions represents one of the leading determinants of increased anisocytosis. Further study of RDW may reveal new insight into inflammation mechanisms. In this review,we specifically discuss the current literature about the association of RDW in various disease conditions involving the gastrointestinal and hepatobiliary systems. We also present some of the related measurements for their value in predicting clinical outcomes in such conditions. According to our data,RDW was found to be a valuable prognostic index in gastrointestinal disorders along with additional inflammatory biomarkers(i.e.,C reactive protein,erythrocyte sedimentation rate,and platelet count) and current disease severity indices used in clinical practice. | Hemant Goyal Giuseppe Lippi Altin Gjymishka Bijo John Rajiv Chhabra Elizabeth May | 2017 | World Journal of Gastroenterology2017，23，27： | 20 |
| 2 | Comparative clinical trial of S-pantoprazole versus racemic pantoprazole in the treatment of gastro-esophageal reflux disease显示文摘AIM: To compare the effi cacy and tolerability of S-pan- toprazole (20 mg once a day) versus racemic Panto- prazole (40 mg once a day) in the treatment of gastro- esophageal reflux disease (GERD). METHODS: This multi-centre, randomized, double-blind clinical trial consisted of 369 patients of either sex suf- fering from GERD. Patients were randomly assigned to receive either one tablet (20 mg) of S-pantoprazole once a day (test group) or 40 mg racemic pantoprazole once a day (reference group) for 28 d. Patients were evaluated for reduction in baseline on d 0, GERD symptom score on d 14 and 28, occurrence of any adverse effect during the course of therapy. Gastrointestinal (GI) endoscopy was performed in 54 patients enrolled at one of the study centers at baseline and on d 28. RESULTS: Signifi cant reduction in the scores (mean and median) for heart burn (P < 0.0001), acid regurgitation (P < 0.0001), bloating (P < 0.0001), nausea (P < 0.0001) and dysphagia (P < 0.001) was achieved in both groups on d 14 with further reduction on continuing the therapy till 28 d. There was a statistically signifi cant difference in the proportion of patients showing improvement in acid regurgitation and bloating on d 14 and 28 (P = 0.004 for acid regurgitation; P = 0.03 for bloating) and heart burn on d 28 (P = 0.01) between the two groups, with a higher proportion in the test group than in the refer- ence group. Absolute risk reductions for heartburn/acid regurgitation/bloating were approximately 15% on d 14 and 10% on d 28. The relative risk reductions were 26%-33% on d 14 and 15% on d 28. GI endoscopy showed no signifi cant difference in healing of esophagitis (P = 1) and gastric erosions (P = 0.27) between the two groups. None of the patients in either group reported any adverse effect during the course of therapy.CONCLUSION: In GERD, S-pantoprazole (20 mg) is more effective than racemic pantoprazole (40 mg) in improving symptoms of heartburn, acid regurgitation, bloating and equally effective in healing esophagitis and gastric erosions. The relative risk reduction is 15%-33%. Both drugs are safe and well tolerated. | Vikas G Pai Nitin V Pai Hemant P Thacker Jaisingh K Shinde Vijay P Mandora Subhash S Erram | 2006 | World Journal of Gastroenterology2006，12，37： | 19 |
| 3 | Identification of EST–SSRs and molecular diversity analysis in Mentha piperita显示文摘EST sequences of Mentha piperita available in the public domain(NCBI) were exploited to develop SSR markers. A total of 1316 ESTs were assembled into 155 contigs and 653 singletons and of these, 110 sequences were found to contain 130 SSRs, with a frequency of1 SSR/3.4 kb. Dinucleotide repeat SSRs were most frequent(72.3%) with the AG/CT(43.8%)repeat motif followed by AT/AT(16.2%). Primers were successfully designed for 68SSR-containing sequences(62.0%). The 68 primers amplified 13 accessions of M. piperita and 54 produced clear amplicons of the expected size. Of these 54, 33(61%) were found to be polymorphic among M. piperita accessions, showing from 2 to 4 alleles with an average of2.33 alleles/SSR, and the polymorphic information content(PIC) value varied between 0.13 and 0.51(average 0.25). All the amplified SSRs showed transferability among four different species of Mentha, with a highest in Mentha arvensis(87.0%) and minimum in Mentha citrata(37.0%). The newly developed SSRs markers were found to be useful for diversity analysis, as they successfully differentiated among species and accessions of Mentha. | Birendra Kumar Umesh Kumar Hemant Kumar Yadav | 2015 | The Crop Journal2015，3，4： | 14 |
| 4 | Hepatitis viruses and non-Hodgkin's lymphoma: A review显示文摘Non-Hodgkin's lymphoma(NHL) is among the haematological malignancies with high prevalence worldwide, causing estimated 355 900 new cases and 191 400 deaths in 2008. High prevalence of NHL is documented in economically more developed areas while low prevalence is observed in less developed areas of the globe. A wide array of environmental factors have been reported to be either directly involved or in modifying the risk of NHL development. In addition to these factors, a number of infectious agents, chiefly viruses have also been implicated in the development of NHL. This article reviews the available literature to discuss the role of hepatitis viruses in NHL development, possible mechanisms of lymphomagenesis and also identify the areas in which further research is required to better understand this disease. A brief discussion on the clinical aspects such as classification, staging, treatment approaches have also been included in this article. | Sibnarayan Datta Soumya Chatterjee Rudragoud S Policegoudra Hemant K Gogoi Lokendra Singh | 2012 | World Journal of Virology2012，1，6： | 11 |
| 5 | Modified scaled distance regression analysis approach for prediction of blast-induced ground vibration in multi-hole blasting显示文摘The blast-induced ground vibration prediction using scaled distance regression analysis is one of the most popular methods employed by engineers for many decades. It uses the maximum charge per delay and distance of monitoring as the major factors for predicting the peak particle velocity(PPV). It is established that the PPV is caused by the maximum charge per delay which varies with the distance of monitoring and site geology. While conducting a production blasting, the waves induced by blasting of different holes interfere destructively with each other, which may result in higher PPV than the predicted value with scaled distance regression analysis. This phenomenon of interference/superimposition of waves is not considered while using scaled distance regression analysis. In this paper, an attempt has been made to compare the predicted values of blast-induced ground vibration using multi-hole trial blasting with single-hole blasting in an opencast coal mine under the same geological condition. Further,the modified prediction equation for the multi-hole trial blasting was obtained using single-hole regression analysis. The error between predicted and actual values of multi-hole blast-induced ground vibration was found to be reduced by 8.5%. | Hemant Agrawal A.K.Mishra | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019，11，1： | 9 |

| 7 | Modified chitosan hydrogels as drug delivery and tissue engineering systems:present status and applications显示文摘Chitosan,a natural cationic polysaccharide,is prepared industrially by the hydrolysis of the aminoacetyl groups of chitin,a naturally available marine polymer.Chitosan is a non-toxic,biocompatible and biodegradable polymer and has attracted considerable interest in a wide range of biomedical and pharmaceutical applications including drug delivery,cosmetics,and tissue engineering.The primary hydroxyl and amine groups located on the backbone of chitosan are responsible for the reactivity of the polymer and also act as sites for chemical modification.However,chitosan has certain limitations for use in controlled drug delivery and tissue engineering.These limitations can be overcome by chemical modification.Thus,modified chitosan hydrogels have gained importance in current research on drug delivery and tissue engineering systems.This paper reviews the general properties of chitosan,various methods of modification,and applications of modified chitosan hydrogels. | Tapan Kumar Giri Amrita Thakur Amit Alexander Ajazuddin Hemant Badwaik Dulal Krishna Tripathi | 2012 | Acta Pharmaceutica Sinica B2012，2，5： | 7 |
| 8 | 提高电子政务接纳程度的策略显示文摘电子政务就是尽可能地使所有的政府活动电子化。电子政务的关键在于对以网络为基础的电子化政府系统和通讯技术的基础设施进行投资。同时,公民的教育水平越高,建设电子政务也就越具有优势。然而,令人惊讶的是,一些ICT(信息和通信技术)基础设施水平较低的国家反而比那些水平较高的国家拥有更高的在线交易能力。本文对电子政务供给和需求两方面的障碍进行检验,试图找到克服这些障碍的策略,并提出:若要有效提高电子政务的采纳程度,除了对ICT进行投资之外,在政府内外增进人们的“技术准备能力”和更为简易地获取ICT的使用途径也同样重要。 | 武玉坤 Hemant Birandranath | 2006 | 电子政务2006，，3： | 6 |
| 9 | Non-cirrhotic hepatocellular carcinoma in chronic viral hepatitis: Current insights and advancements显示文摘Primary liver cancers carry significant morbidity and mortality.Hepatocellular carcinoma(HCC)develops within the hepatic parenchyma and is the most common malignancy originating from the liver.Although 80%of HCCs develop within background cirrhosis,20%may arise in a non-cirrhotic milieu and are referred to non-cirrhotic-HCC(NCHCC).NCHCC is often diagnosed late due to lack of surveillance.In addition,the rising prevalence of non-alcoholic fatty liver disease and diabetes mellitus have increased the risk of developing HCC on noncirrhotic patients.Viral infections such as chronic Hepatitis B and less often chronic hepatitis C with advance fibrosis are associated with NCHCC.NCHCC individuals may have Hepatitis B core antibodies and occult HBV infection,signifying the role of Hepatitis B infection in NCHCC.Given the effectiveness of current antiviral therapies,surgical techniques and locoregional treatment options,nowadays such patients have more options and potential for cure.However,these lesions need early identification with diagnostic models and multiple surveillance strategies to improve overall outcomes.Better understanding of the NCHCC risk factors,tumorigenesis,diagnostic tools and treatment options are critical to improving prognosis and overall outcomes on these patients.In this review,we aim to discuss NCHCC epidemiology,risk factors,and pathogenesis,and elaborate on NCHCC diagnosis and treatment strategies. | Abhilash Perisetti Hemant Goyal Rachana Yendala Ragesh B Thandassery Emmanouil Giorgakis | 2021 | World Journal of Gastroenterology2021，27，24： | 6 |

| 11 | Colon adenoma features and their impact on risk of future advanced adenomas and colorectal cancer显示文摘AIM To review the evidence on the association between specific colon adenoma features and the risk of future colonic neoplasia [adenomas and colorectal cancer(CRC)]. METHODS We performed a literature search using the National Library of Medicine through Pub Med from 1/1/2003 to 5/30/2015. Specific Medical Subject Headings terms(colon, colon polyps, adenomatous polyps, epidemiology, natural history, growth, cancer screening, colonoscopy, CRC) were used in conjunction with subject headings/key words(surveillance, adenoma surveillance, polypectomy surveillance, and serrated adenoma). We defined nonadvanced adenomas as 1-2 adenomas each < 10 mm in size and advanced adenomas as any adenoma ≥ 10 mm size or with > 25% villous histology or high-grade dysplasia. A combined endpoint of advanced neoplasia included advanced adenomas and invasive CRC.RESULTS Our search strategy identified 592 candidate articlesof which 8 met inclusion criteria and were relevant for assessment of histology(low grade vs high grade dysplasia, villous features) and adenoma size. Six of these studies met the accepted quality indicator threshold for overall adenoma detection rate > 25% among study patients. We found 254 articles of which 7 met inclusion criteria for the evaluation of multiple adenomas. Lastly, our search revealed 222 candidate articles of which 6 met inclusion criteria for evaluation of serrated polyps. Our review found that villous features, high grade dysplasia, larger adenoma size, and having ≥ 3 adenomas at baseline are associated with an increased risk of future colonic neoplasia in some but not all studies. Serrated polyps in the proximal colon are associated with an increased risk of future colonic neoplasia, comparable to having a baseline advanced adenoma.CONCLUSION Data on adenoma features and risk of future adenomas and CRC are compelling yet modest in absolute effect size. Future research should refine this risk stratification. | Audrey H Calderwood Karen E Lasser Hemant K Roy | 2016 | World Journal of Gastrointestinal Oncology2016，8，12： | 5 |
| 12 | Training medical undergraduates in the core disciplines of community medicine through community postings-an experience from India显示文摘Objective:Family medicine,epidemiology,health management and health promotion are the core disciplines of community medicine.In this paper,we discuss the development of a commu-nity posting program within the framework of community medicine core disciplines at a primary health centre attached to a teaching hospital in Puducherry,India.Methods:This is a process documentation of our experience.Results:There were some shortcomings which revolved around the central theme that post-ings were conducted with department in the teaching hospital as the focal point,not the primary health centre(PHC).To address the shortcomings,we made some changes in the existing com-munity posting program in 2013.Student feedback aimed at Kirkpatrick level 1(satisfaction)evaluation revealed that they appreciated the benefits of having the posting with PHC as the focal point.Feedback recommended some further changes in the community posting which could be addressed through complete administrative control of the primary health centre as urban health and training center of the teaching hospital;and also through practice of core disciplines of com-munity medicine by faculty of community medicine.Conclusion:It is important to introduce the medical undergraduates to the core disciplines of community medicine early through community postings.Community postings should be con-ducted with primary health centre or urban health and training centre as the focal point. | Hemant Deepak Shewade Chinnakali Palanivel Kathiresan Jeyashree | 2016 | Family Medicine and Community Health2016，4，3： | 5 |
| 13 | Establishment of trauma registry at Queen Elizabeth Central Hospital(QECH), Blantyre, Malawi and mapping of high risk geographic areas for trauma显示文摘BACKGROUND: Less attention is directed toward gaining a better understanding of the burden and prevention of injuries, in low and middle income countries(LMICs). We report the establishment of a trauma registry at the Adult Emergency and Trauma Centre(AETC) at Queen Elizabeth Central Hospital(QECH) in Blantyre, Malawi and identify high risk geographic areas. METHODS: We devised a paper based two-page trauma registry form. Ten data clerks and all AETC clinicians were trained to complete demographic and clinical details respectively. Descriptive data, regression and hotspot analyses were done using STATA 15 statistical package and ArcGIS(16) software respectively.RESULTS: There were 3,747 patients from May 2013 to May 2015. The most common mechanisms of injury were assault(38.2%), and road traffi c injuries(31.6%). The majority had soft tissue injury(53.1%), while 23.8% had no diagnosis indicated. Fractures(OR 19.94 [15.34–25.93]), head injury and internal organ injury(OR 29.5 [16.29–53.4]), and use of ambulance(OR 1.57 [1.06–2.33]) were found to be predictive of increased odds of being admitted to hospital while assault(OR 0.69 [0.52–0.91]) was found to be associated with less odds of being admitted to hospital. Hot spot analysis showed that at 99% confidence interval, Ndirande, Mbayani and Limbe were the top hot spots for injury occurrence. CONCLUSION: We have described the process of establishing an integrated and potentially sustainable trauma registry. Signifi cant data were captured to provide details on the epidemiology of trauma and insight on how care could be improved at AETC and surrounding health facilities. This approach may be relevant in similar poor resource settings. | Linda C.Chokotho Wakisa Mulwafu Mulinda Nyirenda Foster J.Mbomuwa Hemant G.Pandit Grace Le Christopher Lavy | 2019 | World Journal of Emergency Medicine2019，10，1： | 5 |
| 14 | Impact of gout on in-hospital outcomes of acute coronary syndrome-related hospitalizations and revascularizations: Insights from the national inpatient sample显示文摘BACKGROUND Previous studies have established a role of gout in predicting risk and prognosis of cardiovascular diseases. However, large-scale data on the impact of gout on inpatient outcomes of acute coronary syndrome (ACS)-related hospitalizations and post-revascularization is inadequate. AIM To evaluate the impact of gout on in-hospital outcomes of ACS hospitalizations, subsequent healthcare burden and predictors of post-revascularization inpatient mortality. METHODS We used the national inpatient sample (2010-2014) to identify the ACS and goutrelated hospitalizations, relevant comorbidities, revascularization and postrevascularization outcomes using the ICD-9 CM codes. A multivariable analysis was performed to evaluate the predictors of post-revascularization in-hospital mortality. RESULTS We identified 3144744 ACS-related hospitalizations, of which 105198 (3.35%) also had gout. The ACS-gout cohort were more often older white males with a higher prevalence of comorbidities. Coronary artery bypass grafting was required more often in the ACS-gout cohort. Post-revascularization complications including cardiac (3.2% vs 2.9%), respiratory (3.5% vs 2.9%), and hemorrhage (3.1% vs 2.7%) were higher whereas all-cause mortality was lower (2.2% vs 3.0%) in the ACSgout cohort (P < 0.001). An older age (OR 15.63, CI: 5.51-44.39), non-elective admissions (OR 2.00, CI: 1.44-2.79), lower household income (OR 1.44, CI: 1.17- 1.78), and comorbid conditions predicted higher mortality in ACS-gout cohort undergoing revascularization (P < 0.001). Odds of post-revascularization inhospital mortality were lower in Hispanics (OR 0.45, CI: 0.31-0.67) and Asians (OR 0.65, CI: 0.45-0.94) as compared to white (P < 0.001). However, postoperative complications significantly raised mortality odds. Mean length of stay, transfer to other facilities, and hospital charges were higher in the ACS-gout cohort. CONCLUSION Although gout was not independently associated with an increased risk of postrevascularization in-hospital mortality in ACS, it did increase postrevascularization complications. | Rupak Desai Tarang Parekh Hemant Goyal Hee Kong Fong Dipen Zalavadia Nanush Damarlapally Rajkumar Doshi Sejal Savani Gautam Kumar Rajesh Sachdeva | 2019 | World Journal of Cardiology2019，11，5： | 4 |
| 15 | Endoscopic ultrasound-guided vascular interventions: Current insights and emerging techniques显示文摘Endoscopic ultrasound(EUS)is one of the significant breakthroughs in the field of advanced endoscopy.In the last two decades,EUS has evolved from a diagnostic tool to a real-time therapeutic modality.The luminal gastrointestinal(GI)tract provides a unique opportunity to access multiple vascular structures,especially in the mediastinum and abdomen,thus permitting a variety of EUS-guided vascular interventions.The addition of the doppler and contrast-enhanced capability to EUS has further helped provide real-time visualization of blood flow in vessels through the GI tract.EUS-guided vascular interventions rely on standard endoscopic accessories and interventional tools such as fine-needle aspiration needles and fine-needle biopsy.EUS allows the visualization of various structures in real-time by differentiating tissue densities and vascularity,thus,avoiding radiation exposure.EUS-guided techniques also allow real-time microscopic examination after target biopsy.Furthermore,many necessary interventions can be done during the same procedure after diagnosis.This article provides an overview of EUS-guided vascular interventions such as variceal,non-variceal bleeding interventions,EUSguided portal vein(PV)access with the formation of an intrahepatic portosystemic shunt,and techniques related to diagnosis of GI malignancies.Furthermore,we discuss current insights and future outlook of therapeutic modalities like PV embolization,PV sampling,angiography,drug administration,and portal pressure measurement. | Rupinder Mann Hemant Goyal Abhilash Perisetti Saurabh Chandan Sumant Inamdar Benjamin Tharian | 2021 | World Journal of Gastroenterology2021，27，40： | 4 |

| 20 | Design of crown pillar thickness using finite element method and multivariate regression analysis显示文摘Minerals are now being extracted from deep mines due to drying up of resource in shallow ground. The need for suitable supports and ground control mechanisms for safe mining necessitates proper pillar design with filling technology. In addition, high horizontal stress may cause collapse of hanging wall and footwall rocks, hence designing of suitable crown pillars is absolutely necessary for imposing overall safety of the stopes. This paper provides a methodology for the evaluation of the required thickness of crown pillars for safe operation at depth ranging from 600 m to 1000 m. Analyses are conducted with the results of 108 non-linear numerical models considering Drucker-Prager material model in plane strain condition. Material properties of ore body rock and thickness of crown pillars are varied and safety factors of pillars estimated. Then, a generalized statistical relationship between the safety factors of crown pillars with the various input parameters is developed. The developed multivariate regression model is utilized for generating design/stability charts of pillars for different geo-mining conditions.These design charts can be used for the design of crown pillar thickness with the depth of the working,taking into account the changes of the rock mass conditions in underground metal mine. | Kumar Hemant Deb Debasis Chakravarty D. | 2017 | International Journal of Mining Science and Technology2017，27，6： | 3 |
