Mrinal Pahwa,Archna R. Pahwa,Mohit Girotra,Arun Chawla 대한비뇨의학회 2013 Investigative and Clinical Urology Vol.54 No.9

Isolated renal mucormycosis is rarely identified and has been described in only a handful of cases. We hereby report a case of isolated renal mucormycosis with an atypical presentation in an immunocompetent patient with no identifiable risk factors. A 30-year-old nondiabetic male presented with a poorly functioning right kidney with minimal constitutional symptoms. The patient underwent a right simple nephrectomy. Histopathology revealed necrotizing xanthogranulomatous pyelonephritis with mucormycosis. The postoperative period was uneventful and the patient was managed without any antifungal administration. We hereby emphasize that renal mucormycosis can affect immunocompetent healthy adults without any previously known risk factors and that asymptomatic patients with no evidence of fungemia or disseminated disease can be managed without administration of intravenous amphotericin.

Bibliometric analysis is of paramount importance in assessing the research impact wherein studies are ranked on the basis of citations received. It also brings out the excellent contribution of authors and journals in adding evidence for future research. This study aimed at evaluating the top 100 most cited articles on anterior communicating artery (ACoA) Aneurysms. Scopus database was searched using title specific search for the aneurysm of ACoA and top 100 most cited articles along with their authors, author IDs, affiliated institutions, countries and funding bodies were identified. Search yielded 841 articles and top 100 articles were identified to include in this analysis which secured 5615 citations. Citations per year was also calculated to minimize the risk of bias. Maximum citations by any article were 242. The United States was the major contributor to the number of articles while Kessler Institute for Rehabilitation became the highest contributing institution. DeLuca J proved to be a pioneer in this specialized area as he penned 6 studies being first author in 4 of them, making him the most frequent author. National Institutes of Health and the U.S. Department of Health and Human Services were the main funding bodies. Subcategory analysis revealed, 50% studies provided evidence for the treatment and the surgical outcome of the aneurysm. Studies like these can aid in better neurological and neurosurgical management in decision making of ACoA aneurysm.

Planfulness Ability as a Mediator of the Relationship between Learning from Supervisor and Readiness for Change: Empirical Evidence from India

Mohit Pahwa,Santosh Rangnekar 한국데이터전략학회 2023 Journal of information technology applications & m Vol.30 No.5

The present research aims to examine whether learning from the supervisor influences readiness for change with the mediating impact of planfulness. Drawing upon the theory of planned behavior, it is hypothesized that learning from the supervisor positively impacts planfulness ability in individuals, which in turn enhances the readiness for change. Through using convenience sampling, the sample of 451 was collected from employees working full-time in the manufacturing and I.T. service organizations in India. Structural equation modeling and regression analysis indicate that learning from the supervisor is positively associated with readiness for change and planfulness. Additionally, planfulness fully mediated the relationship between learning from the supervisor and readiness to change. The findings of the present research highlight that continuous support and learning from the supervisor enhances the planfulness ability of the individual and consequently enhances individual readiness for change. The current research is pioneering in testing the hypothetical model associating learning from the supervisor, planfulness, and readiness for change.

Visual Quality Improvement of Medical Images using Pixel Reconstruction Followed by Gabor Enhancement Technique

Pooja Gupta,Kuldip Pahwa 보안공학연구지원센터(IJSIP) 2014 International Journal of Signal Processing, Image Vol.7 No.6

Today is an era of digital imaging. This can be viewed either in the field of photography or in the field of medical imaging. Digital imaging has improved the performance of picture quality. Detailed information can be recovered very quickly from any part of an image and this feature has become very useful in every field of imaging. This improvement in the field of medical imaging has given life to so many patients as diagnosis of disease has become very fast and easy. But many a times the image quality is not upto the mark, due to this reason; the doctors are not able to diagnose the disease. So this paper proposes a noval approach for improvement in quality of medical images using pixel reconstruction followed by Gabor filter enhancement technique. The experimental results are verified as improvement in PSNR of hexagonal pixel images as compared with square pixel images. The results show a large improvement in quality of digital imaging.

Establishing a Policy Framework for the Primary Prevention of Occupational Cancer: A Proposal Based on a Prospective Health Policy Analysis

Veglia, Amanda,Pahwa, Manisha,Demers, Paul A. Occupational Safety and Health Research Institute 2017 Safety and health at work Vol.8 No.1

Background: Despite our knowledge of the causes of cancer, millions of workers are involuntarily exposed to a wide range of known and suspected carcinogens in the workplace. To address this issue from a policy perspective, we developed a policy framework based on a prospective health policy analysis. Use of the framework was demonstrated for developing policies to prevent cancers associated with diesel engine exhaust (DEE), asbestos, and shift work, three occupational carcinogens with global reach and large cancer impact. Methods: An environmental scan of existing prospective health policy analyses was conducted to select and describe our framework parameters. These parameters were augmented by considerations unique to occupational cancer. Policy-related resources, predominantly from Canada, were used to demonstrate how the framework can be applied to cancers associated with DEE, asbestos, and shift work. Results: The parameters of the framework were: problem statement, context, jurisdictional evidence, primary prevention policy options, and key policy players and their attributes. Applying the framework to the three selected carcinogens illustrated multiple avenues for primary prevention, including establishing an occupational exposure limit for DEE, banning asbestos, and improving shift schedules. The framework emphasized the need for leadership by employers and government. Conclusion: To our knowledge, this is the first proposal for a comprehensive policy framework dedicated to the primary prevention of occupational cancer. The framework can be adapted and applied by key policy players in Canada and other countries as a guide of what parameters to consider when developing policies to protect workers' health.

Spontaneous Rectal Perforation with Transanal Evisceration of the Small Bowel: A Rare Case Report

Pal Ajay Kumar,Kumar Prasoon,Yadav Dhirendra,Kumar Awanish,Pahwa Harvinder Singh,Singh Krishna Kant 대한외상중환자외과학회 2022 Journal of Acute Care Surgery Vol.12 No.2

Transanal evisceration of the small bowel is a rare surgical emergency. Rectal perforation in such cases is usually due to an underlying rectal prolapse. We report a case of a middle aged (45 years) male with spontaneous rectal perforation and transanal evisceration of the small bowel. Approximately 150 cm of small bowel had eviscerated transanally and the patient required emergent abdominal exploration, reposition of the small bowel, and repair of the rectal perforation. Small bowel evisceration through the anal verge is an emergent condition and the aim was to prevent life threatening complications related to sepsis.

Priority Setting for Occupational Cancer Prevention

Peters, Cheryl E.,Palmer, Alison L.,Telfer, Joanne,Ge, Calvin B.,Hall, Amy L.,Davies, Hugh W.,Pahwa, Manisha,Demers, Paul A. Occupational Safety and Health Research Institute 2018 Safety and health at work Vol.9 No.2

Background: Selecting priority occupational carcinogens is important for cancer prevention efforts; however, standardized selection methods are not available. The objective of this paper was to describe the methods used by CAREX Canada in 2015 to establish priorities for preventing occupational cancer, with a focus on exposure estimation and descriptive profiles. Methods: Four criteria were used in an expert assessment process to guide carcinogen prioritization: (1) the likelihood of presence and/or use in Canadian workplaces; (2) toxicity of the substance (strength of evidence for carcinogenicity and other health effects); (3) feasibility of producing a carcinogen profile and/or an occupational estimate; and (4) special interest from the public/scientific community. Carcinogens were ranked as high, medium or low priority based on specific conditions regarding these criteria, and stakeholder input was incorporated. Priorities were set separately for the creation of new carcinogen profiles and for new occupational exposure estimates. Results: Overall, 246 agents were reviewed for inclusion in the occupational priorities list. For carcinogen profile generation, 103 were prioritized (11 high, 33 medium, and 59 low priority), and 36 carcinogens were deemed priorities for occupational exposure estimation (13 high, 17 medium, and 6 low priority). Conclusion: Prioritizing and ranking occupational carcinogens is required for a variety of purposes, including research, resource allocation at different jurisdictional levels, calculations of occupational cancer burden, and planning of CAREX-type projects in different countries. This paper outlines how this process was achieved in Canada; this may provide a model for other countries and jurisdictions as a part of occupational cancer prevention efforts.
