Purpose: This study compared a) crestal bone loss, b) implant stability quotient (ISQ), c) probing depth, d) denture fracture incidence, and e) posterior residual ridge resorption (RRR) of two implant and single implant-supported overdentures and assessed the quality of life (QOL) was evaluated before and after giving the prosthesis. Materials and Methods: The study was a randomized longitudinal cohort study. Eighty subjects were selected for the study and divided randomly into two groups (n=40): Group 2IOD— two implant-supported overdentures; Group 1IOD— Single implant-supported overdentures. Except for the number of implants, the common surgical, implant, and the prosthetic protocol was followed for the two groups. An oral health impact profile EDENT questionnaire was completed by the patients before giving the implant-supported overdenture and after one year of prosthesis delivery to evaluate the effects of oral health on the quality of life. Probing pocket depth (mm), ISQ (resonance frequency analysis), denture fracture incidence, posterior RRR (mm), and crestal bone loss (mm) were assessed and compared at the baseline and one year after implant placement (early loading protocol) for the two groups. Standard statistical tests, including an unpaired t-test with SPSS software, were used for the analysis. Results: The average crestal bone loss in group 2IOD was insignificantly lower than group 1IOD. The ISQ values were higher for group 2IOD than group 1IOD at one year. The ISQ values for both groups at 12 months were similar (P>0.05). The probing depth at both time intervals yielded insignificant intergroup differences. No denture fracture was reported in either group. At 12 months, posterior ridge resorption in group 2IOD was 0.33±0.08, which was significantly lower than in group 1IOD. Conclusions: A one implant-supported overdenture is a comparable treatment option with two implant-supported overdentures for edentulous patients, having the advantages of lower cost and less surgical trauma. However, there may be more posterior RRR with this treatment modality.

An improved privacy preservation technique in health-cloud

Mayank Kumar Kundalwal,Kakali Chatterjee,Ashish Singh 한국통신학회 2019 ICT Express Vol.5 No.3

In today’s cloud computing environment, health-cloud preserve the person specific sensitive information for several purposes such as bio-medical research, health insurance companies, medical data analysis, etc. When any authorized person access these clouds, the released data should not compromise any individuals’ privacy and it remains useful as well. In the health-cloud system, the data must be released in such a way that any individuals’ identity cannot be revealed. The database management system alone cannot ensure any individual’s privacy. The Access Control (AC) models are also not able to protect the data from indirect access or multiple queries. To remove such issues inference control is one of the techniques which ensures the data confidentiality from indirect data access. In this paper, we have proposed a hybrid technique which includes two different inference control techniques, query set size restriction and k-anonymity to ensure individuals’ privacy. A query set size restriction is used to prevent the sensitive data from inference attacks, whereas k-anonymity is implemented to protect the data from linking attacks. Both these techniques reach a certain privacy level with satisfactory data utilization. We have also generated a rule set to increase the privacy of healthcare data.

Composite Membranes Prepared by Polyvinyl Alcohol-Maleic Acid onto Polysulfone: Separation Performance of Tea Polyphenol

Mayank Saxena,P. S. Singh,A. Bhattacharya 한국고분자학회 2022 Macromolecular Research Vol.30 No.8

Poly(vinyl alcohol) (PVA)-coated membranes on polysulfone (PS) were cross-linked using maleic acid. The membrane properties (viz. hydrophilicity) were tailored for the ester linkage due to PVA and maleic acid cross-linking. The separation of tea polyphenol by PS-PVA composite membrane was investigated in this study. Cross-linked PVA coated on two different molecular weight cut-off (MWCO) PS membrane systems was prepared for this purpose. The permeation flux and separation for tea polyphenol are the criteria for evaluation. The separation of tea-polyphenol follows the trend PS-PVA-IV > PS-PVA-III > PS-PVA-II > PS-PVA-I. Higher dilution deteriorated the tea-polyphenol separation performance of the membranes. The membranes showed their best performance at pH 6.5. The time dependence separation performance study revealed the order PS-PVA-IV > PS-PVA-III > PS-PVA-II > PS-PVA-I membranes.

An Updated Systematic Review and Meta-Analysis for the Diagnostic Test Accuracy of Ascitic Fluid Adenosine Deaminase in Tuberculous Peritonitis

Mahajan Mayank,Prasad Manohar Lal,Kumar Pramod,Kumar Amit,Chatterjee Neha,Singh Shreya,Marandi Sujeet,Prasad Manoj Kumar 대한감염학회 2023 Infection and Chemotherapy Vol.55 No.2

Background: Tuberculous peritonitis is difficult to diagnose due to its non-specific clinical manifestations and lack of proper diagnostic modalities. Current meta-analysis was performed to find the overall diagnostic accuracy of adenosine deaminase (ADA) in diagnosing tuberculous peritonitis. Materials and Methods: PubMed, Google Scholar, and Cochrane library were searched to retrieve the published studies which assessed the role of ascitic fluid ADA in diagnosing tuberculous peritonitis from Jan 1980 to June 2022. This meta-analysis included 20 studies and 2,291 participants after fulfilling the inclusion criteria. Results: The pooled sensitivity was 0.90 (95% confidence interval [CI]: 0.85 - 0.94) and pooled specificity was 0.94 (95% CI: 0.92 - 0.95). The positive likelihood ratio was 15.20 (95% CI: 11.70 - 19.80), negative likelihood ratio was 0.10 (95% CI: 0.07 - 0.16) and diagnostic odds ratio was 149 (95% CI: 86 - 255). The area under the summary receiver operating characteristic curve was 0.97. Cut- off value and sample size were found to be the sources of heterogeneity in the mete-regression analysis. Conclusion: Ascitic fluid ADA is a useful test for the diagnosis of tuberculous peritonitis with good sensitivity and specificity however, with very low certainty of evidence evaluated by Grading of Recommendations, Assessment, Development and Evaluation approach. Further well- designed studies are needed to validate the diagnostic accuracy of ascitic fluid ADA for tuberculous peritonitis.

Sex and Gender Differences in Stroke and Their Practical Implications in Acute Care

Johanna Ospel,Nishita Singh,Aravind Ganesh,Mayank Goyal 대한뇌졸중학회 2023 Journal of stroke Vol.25 No.1

There are several controversies regarding the role of sex and gender in the pathophysiology and management of acute stroke. Assessing the role of sex, i.e., biological/pathophysiological factors, and gender, i.e., sociocultural factors, in isolation is often not possible since they are closely intertwined with each other. To complicate matters even more, the functional baseline status of women and men at the time of their first stroke is substantially different, whereby women have, on average, a poorer reported/ascertained baseline function compared to men. These differences in baseline variables account for a large part of the differences in post-stroke outcomes between women and men. Adjusting for these baseline differences is difficult, and in many cases, residual confounding cannot be excluded. Despite these obstacles, a better understanding of how patient sex and gender differences influence acute stroke and stroke care pathways is crucial to avoid biases and allow us to provide the best possible care for all acute stroke patients. Disregarding patient sex and gender on one hand and ignoring potential confounding factors in sex- and gender-stratified analyses on the other hand, may cause researchers to come to erroneous conclusions and physicians to provide suboptimal care. This review outlines sex- and gender-related factors in key aspects of acute stroke, including acute stroke epidemiology, diagnosis, access to care, treatment outcomes, and post-acute care. We also attempt to outline knowledge gaps, which deserve to be studied in further detail, and practical implications for physicians treating acute stroke patients in their daily practice.

Background and Objectives: Cochlear implantation in late implanted prelinguals necessitates a complex decision-making process for clinicians and patients due to the uncertainty of achieving adequate benefit in auditory and speech perception. This study longitudinally evaluated clinical and social outcomes of prelingually deaf children with implantation in their late childhood.Subjects and Methods: A total of 113 (49 females and 64 males) participants, with an age range of 5-15 years, were assessed for the pre-implant parameters such as hearing loss etiology, aided responses, anatomical aspects, and psychological evaluation. The Category of Auditory Performance, Speech Awareness Threshold, Speech Reception Threshold, and Speech Discrimination Score were administered to assess the patient’s auditory skills. Further, the Speech Intelligibility Rating scale was administered to evaluate the patient’s speech intelligibility at 3, 6, 9, 12, 18, and 24 months post-surgery. Subjectively perceived benefits were evaluated using the satisfaction rating scale and a questionnaire.Results: The statistical results showed a significant impact of cochlear implantation in all domains. Positive impact and improvement post-implantation were noted in all the spheres, including auditory, linguistic, social, and educational.Conclusions: The study highlighted that the outcomes of a cochlear implant at a later age might not parallel with the implantation at a younger age. However, this still provides measurable benefits even after a longer period of auditory deprivation.

A complete 3D map of Bell Glasstone spatial correction factors for BRAHMMA subcritical core

Shukla Shefali,Roy Tushar,Kashyap Yogesh,Shukla Mayank,Singh Prashant 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.9

Accelerator driven subcritical systems have long been discussed as facilities which can be used for solving the nuclear waste problem. The physics of these systems is very different from conventional reactors and new techniques had to be developed for reactivity monitoring. One such technique is the Area Ratio Method which studies the response of a subcritical system upon insertion of a large number of neutron pulses. An issue associated with this technique is the spatial dependence of measured reactivity which is intrinsic to the sub criticality of the system since the reactor does not operate on the fundamental mode and measured reactivity depends on the detector position. This is generally addressed by defining Bell-Glasstone spatial correction factor. This factor upon multiplication with measured reactivity gives the correct reactivity which is independent of detector location. Monte Carlo Methods are used for evaluating these factors. This paper presents a complete three dimensional map of spatial correction factors for BRAHMMA subcritical system. In addition, the dataset obtained also helps in identifying detector locations where the correction factor is close to unity, thereby implying no correction if the detector is used at those locations. © 2022 Korean Nuclear Society, Publish

A Program Model Based Regression Test Selection Technique For D Programming Language

Nitesh Chouhan,Dr. Maitreyee Dutta,Dr. Mayank Singh 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.6

Software testing can be stated as the process of validating and verifying that a computer program, application and product [1]. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Software testing, depending on the testing method employed, can be implemented at any time in the development process. Traditionally most of the test effort occurs after the requirements have been defined and the coding process has been completed. Testing can never completely identify all the defects within software. A primary purpose of testing is to detect software failures so that defects may be discovered and corrected. Testing cannot establish that a product functions properly under all conditions but can only establish that it does not function properly under specific conditions. There are many approaches to software testing. Reviews, walkthroughs, or inspections are referred to as static testing, whereas actually executing programmed code with a given set of test cases is referred to as dynamic testing. Regression testing is an important but expensive software maintenance activity performed with the aim of providing confidence in modified software. Regression test selection techniques reduce the cost of regression testing by selecting test cases for a modified program from a previously existing test suite. Regression testing is done every time when a program is modified to ensure that the modifications do not introduce new bugs into previously validated code. Regressions Testing can be done by collectively perform Regression Test Selection, Test Minimization and Test Case Priotrization Technique. An important research problem, in this context, is the selection of a relevant subset of test cases from the initial test suite. Regression test selection (RTS) techniques minimize both the regression testing time and effort. Regression test selection (RTS) techniques select a subset of valid test cases from an initial test suite (T) to test that the affected but unmodified parts of a program continue to work correctly. Use of an effective regression test selection technique can help to reduce the testing costs in environments in which a program undergoes frequent modifications. D is a new programming language. This is an object-oriented, imperative, multi-paradigm system programming language. Regression testing on D programming language still untouched by researchers. Our research attempts to bridge this gap by introducing a techniques to revalidate D programs. A framework is proposed which automates both the regression test selection and regression testing processes for D programming language. As part of this approach, special consideration is given to the analysis of the source code of D language. In our approach system dependence graph representation will be used for regression test selection for analyzing and comparing the code changes of original and modified program. First we construct a system dependence graph of the original program from the source code. When some modification is executed in a program, the constructed graph is updated to reflect the changes. Our approach in addition to capturing control and data dependencies represents the dependencies arising from object-relations. The test cases that exercise the affected model elements in the program model are selected for regression testing. Empirical studies carried out by us show that our technique selects on an average of 26.36. % more fault-revealing test cases compared to a UML based technique while incurring about 37.34% increase in regression test suite size.
