Purpose: A prospective study evaluating impact of percutaneous nephrolithotomy (PCNL) on renal function following PCNL using ethylenedicysteine (EC) renal scan. Does multiplicity of access tracts play a role?Materials and Methods: A prospective observational study was done and patients undergoing PCNL for renal calculi at our urology department were selected. Renal Tc99m EC scan was done pre-surgery and at 3 months follow-up. An assessment was done on decline in glomerular filtration rate (GFR) in postoperative period based on number of access tracts required. Results: A total of 110 patients were enrolled in the study. The total number of punctures was 170 with 141 being supra-costal puncture and 29 infra-costal. The total number of single punctures were 60 and classified as Group I whereas patients with double puncture and triple puncture (40 and 10 patients, respectively) were classified as Group II. Mean postoperative split renal function (in Tc99m EC scans) of patients of Group I (40.93±19.62%) was found to be higher than that of Group II (32.82±16.98%). Mean change (decline) in GFR for single, double and triple tracts were 2.68 mL/min, 3.80 mL/min, and 4.2 mL/min, respectively. Conclusions: PCNL used for stone removal can improve renal function by eradicating obstruction; however, this procedure may itself negatively impact the functions of the targeted kidney. Our study showed post PCNL decrease in GFR which worsens with an increasing number of accesses.
Open Access Publishing in India: Coverage, Relevance, and Future Perspectives
Durga Prasanna Misra,Vikas Agarwal 대한의학회 2019 Journal of Korean medical science Vol.34 No.27
Open access (OA) publishing is a recent phenomenon in scientific publishing, enabling free access to knowledge worldwide. In the Indian context, OA to science has been facilitated by government-funded repositories of student and doctoral theses, and many Indian society journals are published with platinum OA. The proportion of OA publications from India is significant in a global context, and Indian journals are increasingly available on OA repositories such as Pubmed Central, and Directory of Open Access Journals. However, OA in India faces numerous challenges, including low-quality or predatory OA journals, and the paucity of funds to afford gold OA publication charges. There is a need to increase awareness amongst Indian academics regarding publication practices, including OA, and its potential benefits, and utilize this modality of publication whenever feasible, as in publicly-funded research, or when platinum OA is available, while avoiding falling prey to poor quality OA journals.
A Novel encrypted XML streaming technique for indexing data on multiple channels
Vinay K. Ahlawat,Gaurav Agarwal,Vikas Goel,Kueh Lee Hui,Mangal Sain Korean Society for Internet Information 2024 KSII Transactions on Internet and Information Syst Vol.18 No.7
In this study, we focus on addressing the functional domain of research related to indexing XML data in wireless networks, emphasizing ensuring data confidentiality. The abstract outlines a novel indexing method designed for broadcasting encrypted XML data over wireless networks. The proposed technique involves two channels: one for indexing and another for transmitting the actual XML data. The method ensures data security by encrypting the XML stream, allowing mobile devices to access only authorized bits based on their access permissions. Despite an increase in data access time and device tuning time, the study concludes that the proposed indexing technique significantly enhances the security of transmitting XML data over mobile wireless networks.

India is home to the world’s second largest population. Rheumatology is an emerging specialty in India. We reviewed organization, epidemiology and training facilities for Rheumatology in India. Also, we also looked at publications in the field of rheumatology from India from over the past six years using Scopus and Medline databases. Despite rheumatologic disorders affecting 6%-24% of the population, rheumatology in India is still in its infancy. Till recently, there were as few as two centers in the country training less than five fellows per year. However, acute shortage of specialists and increasing patient numbers led to heightened awareness regarding the need to train rheumatologists. Subsequently, six new centers have now started 3-year training programs in rheumatology. The epidemiology of rheumatic diseases in India is being actively studies under the Community Oriented Programme for Control of Rheumatic Diseases (COPCORD) initiative. The most number of publications on rheumatic diseases from India are on rheumatoid arthritis, lupus and osteoporosis, many of which have been widely cited. Major collaborators worldwide are USA, UK and France, whereas those from Asia are Japan, Saudi Arabia and Singapore. The Indian Rheumatology Association (IRA) is the national organization of rheumatologists. The flagship publication of the IRA, the Indian Journal of Rheumatology, is indexed in Scopus and Embase. To conclude, rheumatology in India is an actively expanding and productive field with significant contributions to world literature. There is a need to train more personnel in the subject in India.
Reporting Survey Based Studies – a Primer for Authors
Prithvi Sanjeevkumar Gaur,Olena Zimba,Vikas Agarwal,Latika Gupta 대한의학회 2020 Journal of Korean medical science Vol.35 No.45
The coronavirus disease 2019 (COVID-19) pandemic has led to a massive rise in survey-based research. The paucity of perspicuous guidelines for conducting surveys may pose a challenge to the conduct of ethical, valid and meticulous research. The aim of this paper is to guide authors aiming to publish in scholarly journals regarding the methods and means to carry out surveys for valid outcomes. The paper outlines the various aspects, from planning, execution and dissemination of surveys followed by the data analysis and choosing target journals. While providing a comprehensive understanding of the scenarios most conducive to carrying out a survey, the role of ethical approval, survey validation and pilot testing, this brief delves deeper into the survey designs, methods of dissemination, the ways to secure and maintain data anonymity, the various analytical approaches, the reporting techniques and the process of choosing the appropriate journal. Further, the authors analyze retracted survey-based studies and the reasons for the same. This review article intends to guide authors to improve the quality of survey-based research by describing the essential tools and means to do the same with the hope to improve the utility of such studies.
Integrity of Authorship and Peer Review Practices: Challenges and Opportunities for Improvement
Durga Prasanna Misra,Vinod Ravindran,Vikas Agarwal 대한의학회 2018 Journal of Korean medical science Vol.33 No.46
Integrity of authorship and peer review practices are important considerations for ethical publishing. Criteria for authorship, as delineated in the guidelines by the International Committee of Medical Journal Editors (ICMJE), have undergone evolution over the decades, and now require fulfillment of four criteria, including the need to be able to take responsibility for all aspects of the manuscript in question. Although such updated authorship criteria were published nearly five years ago, still, many major medical and specialist journals have yet to revise their author instructions to conform to this. Inappropriate authorship practices may include gift, guest or ghost authorship. Existing literature suggests that such practices are still widely prevalent, especially in non-English speaking countries. Another emerging problem is that of peer review fraud, mostly by authors, but also rarely by handling editors. There is literature to suggest that a proportion of such fake peer review may be driven by the support of some unscrupulous external editing agencies. Such inappropriate practices with authorship malpractices or disagreement, or peer review fraud, have resulted in more than 600 retractions each, as identified on the retractions database of Retractionwatch.com. There is a need to generate greater awareness, especially in authors from non-English speaking regions of the world, about inappropriate authorship and unethical practices in peer review. Also, support of any external editing agency should be clearly disclosed by authors at the time of submission of a manuscript.
