ABSTRACT
Background: After collection of blood from a blood donor, it undergoes certain tests for its suitability for transfusion to a recipient. According to the Red Cross, women should have at least a hemoglobin level of 12.5 g/dL and men should have 13 g/dL. Aim and Objectives: The aim of the study was to observe the hemoglobin level of donated blood according to the sex and according to the blood groups – A, AB, B, and O. Materials and Methods: This cross-sectional data audit was conducted with the data of males and females from a blood bank of a tertiary care hospital in India. A total of 4 years of data from 2013 to 2016 were analyzed. The hemoglobin levels were tested by the Shapiro–Wilk normality test. The distribution was not normal. Hence, data were presented as median (first quartile–third quartile) and tested by nonparametric tests – Mann–Whitney test and Kruskal–Wallis test. Results: Total data of 7026 blood donors (6658 [94.76%] males and 368 [5.24%] females) were analyzed in this study. The level is above the cutoff suggested by Red Cross. The overall hemoglobin level was 13.8 (13.2?14.1) g/dL. Male had higher hemoglobin 13.8 (13.2?14.2) g/dL than females 13 (13?13.5) g/dL, P < 0.0001. There was no difference in hemoglobin in A, AB, B, and O blood group in overall, males, and females. Conclusion: There were more male blood donors than female donors. Males have higher hemoglobin levels than females in all types of blood groups in the ABO system. There was no difference in hemoglobin concentration in different blood groups.
ABSTRACT
Background: Peer review is one of the cornerstones of sound scientific publication. When a paper is submitted to a journal, after an initial assessment, the editor sends the article to reviewers with similar research experiences for comprehensive comments. Aims and Objectives: In this article, we aimed to analyze the pattern of peer review by the reviewers in the physiology domain from India as found in publons.com. Materials and methods: We searched https://publons.com and clicked on 揃rowse� to search the profile of 揜esearchers.� The research field was selected as 揚hysiology� and the country as 揑ndia.� A total of 158 profiles were found with the search criteria. The number of publications, citations, peer review, H-index, and the editorial record was obtained for further analysis. The number of the peer review was tested with the number of publications and citations for any existing correlation. Results: Among the 158 researchers in the physiology domain, an average verified review was 8.09 � 32.12 and an average number of publications were 15.7 � 31.1. Their number of citations was 359.75 � 1296.24 with an average H-index of 4.15 � 7.85. There was a significant positive correlation with peer review versus number of publication (0.39 [95% CI: 0.24 to 0.51], P < 0.0001) and peer review versus number of citation (0.26 [95% CI: 0.11 to 0.41)], P = 0.0008). Conclusion: Peer reviewers in the physiology domain from India have contributed by reviewing an average of 8 peer reviews. However, many of the profiles showed zero contribution. More publications and more citations would expose the researchers to a wider audience worldwide, including the editors. Hence, they would get peer review requests.
