Prognostic model to predict postoperative acute kidney injury in patients undergoing major gastrointestinal surgery based on a national prospective observational cohort study.

Background: Acute illness, existing co-morbidities and surgical stress response can all contribute to postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. The aim of this study was prospectively to develop a pragmatic prognostic model to stratify patients according to risk of developing AKI after major gastrointestinal surgery. Methods: This prospective multicentre cohort study included consecutive adults undergoing elective or emergency gastrointestinal resection, liver resection or stoma reversal in 2-week blocks over a continuous 3-month period. The primary outcome was the rate of AKI within 7 days of surgery. Bootstrap stability was used to select clinically plausible risk factors into the model. Internal model validation was carried out by bootstrap validation. Results: A total of 4544 patients were included across 173 centres in the UK and Ireland. The overall rate of AKI was 14·2 per cent (646 of 4544) and the 30-day mortality rate was 1·8 per cent (84 of 4544). Stage 1 AKI was significantly associated with 30-day mortality (unadjusted odds ratio 7·61, 95 per cent c.i. 4·49 to 12·90; P < 0·001), with increasing odds of death with each AKI stage. Six variables were selected for inclusion in the prognostic model: age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Internal validation demonstrated good model discrimination (c-statistic 0·65). Discussion: Following major gastrointestinal surgery, AKI occurred in one in seven patients. This preoperative prognostic model identified patients at high risk of postoperative AKI. Validation in an independent data set is required to ensure generalizability

Preparation and Application of Electrodes in Capacitive Deionization (CDI): a State-of-Art Review

As a promising desalination technology, capacitive deionization (CDI) have shown practicality and cost-effectiveness in brackish water treatment. Developing more efficient electrode materials is the key to improving salt removal performance. This work reviewed current progress on electrode fabrication in application of CDI. Fundamental principal (e.g. EDL theory and adsorption isotherms) and process factors (e.g. pore distribution, potential, salt type and concentration) of CDI performance were presented first. It was then followed by in-depth discussion and comparison on properties and fabrication technique of different electrodes, including carbon aerogel, activated carbon, carbon nanotubes, graphene and ordered mesoporous carbon. Finally, polyaniline as conductive polymer and its potential application as CDI electrode-enhancing materials were also discussed

JOURNAL OF CLINICAL BIOCHEMISTRY AND NUTRITION: A BIBLIOMETRIC ANALYSIS

Journal of Clinical Biochemistry and Nutrition is a bi-monthly journal, currently published from Japan by the Society for free Radical Research. It publishes six issues in a year. The study examines the article published in the Journal of Clinical Biochemistry and Nutrition from 2007 to 2017. This paper aimed to assess growth pattern of research output, authorship pattern, degree of collaboration, ranking of authors based on productivity and h-index, most cited references, type of items produced, keyword wise distribution, most productive countries and most productive institutions, distributions of research output and also estimate the future growth of publications using straight line equation. There are 813 articles were published during 2007-2017(11 years). The highest number of 88 articles were published in 2009 and lowest number of 63 articles published in 2007. Majority of the contributions are more than five authors. There exists a higher level of collaborations between the authors. Naito Y is the most productive author ranked in first position and Suzuki H, Yoshikawa T and Watanabe K are each of them having h-index score 9 who are placed in the first rank. this study also reveals the highly cited papers in Journal of Clinical Biochemistry and Nutrition. Most of the research outputs in the journal are articles. ‘Induced’ is the keyword which is mostly occurred in the journal. Nearly one-third of the articles were published in Japan. It is known that different institutions were involved in the publication of articles, from these top most productive institutions are listed. It is estimated that research output of the source journal may take slightly increasing future

A SCIENTOMETRIC ANALYSIS OF RESEARCH JOURNAL OF CHEMISTRY AND ENVIRONMENT (2005-2019)

In this study presents the Scientometric analysis of the Research Journal Chemistry and Environment during the year 2005 to 2019. The study reveals that the total no. of articles 1,470 include 1,408 Research Articles, 45 Reviews, 10 Mini Reviews and 7 Short Communications were published in this journal has been carried out. Fifteen volumes of the journal containing 24 issues from 2005 to 2012 (Quarterly Journal) and it updated to Monthly journal from 2013 to 2019 it containing 84 issues (totally 108 issues) have been taken into consideration for the present study. The number of contributions, authorship pattern, author productivity, average citations, and collaborative papers of all necessary information are compiled, recorded, tabulated and analysed for making observations as indicated in the study

Dosimetric evaluation of 6 MV and 18 MV intensity-modulated radiotherapy plans for treatment of carcinoma of the cervix

Introduction: Cervical cancer (Ca Cx) is the fourth most frequent cancer in women with an estimated 57000 new cases in 2018 representing 6.6% of all female cancers. Approximately 90% of deaths from cervical cancer occurred in low- and middle-income countries. Material and Methods: A retrospective radiotherapy treatment planning comparative study conducted at the Department of Radiation Physics, Kidwai Memorial Institute of Oncology, Bangalore during June 2018- March 2019. Result: All the plans were normalized to 100 % at Target mean to achieve a similar target dose for quantitative comparison of DVHs. The results for target coverage, OAR sparing, integral dose, and monitoring units. Conclusions: The tradeoff of using 6 MV and 18 MV for cervix patients depends on many parameters. Since the same PTV coverage was forced for both energies by having the same optimization constraints, there was little difference in target coverage and conformity index for both energies
