Coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a global health problem, India being the second most affected country. The kinetics of antibody response to SARS-CoV-2 in Indian population is not studied yet. To understand serological response in relation to age, gender, time period and severity of disease, Roche Elecsys anti-SARS-CoV-2 test was used which analysed both IgM and IgG. One hundred and three COVID-19 patients were enrolled. Seropositivity was seen in 64% of patients, with 33% at ≤ 7 days, 62% between 8 and 15 days and 81% at ≥ 16 days from the time of admission. Men (65%) showed higher antibody response than women (59%), whereas no difference was observed in seropositivity with respect to age of the patients. Dynamics of antibody responses revealed individual variations. Patients in ICU had higher antibody reactivity with 67% positivity as compared to 60% positivity in non-ICU patients. Kinetics of antibody response during COVID-19 disease varied in relation to gender, age, time period and severity and these factors might play an important role in treatment and control of COVID-19.  相似文献

Leadership, as a topic, has seen a lot of interest in academics as well as with practitioners. The search, however, has not yielded a concrete formula, though there are quite a few theories which have worked well in certain contexts. The context of special libraries is one such area which has a huge potential in discovering what leadership actions have worked well and what can be a framework for success in other special libraries, especially when the utility of special libraries is being questioned in a corporate environment. The dearth of leadership and leadership development literature in special libraries, from a practitioner's point of view, provides a good opportunity for sharing a small journey of success. The column builds upon the application of leadership actions deriving from diverse and merging fields like learning and development, organizational behavior, marketing, and human psychology of reading in making a case for the utility of corporate libraries in the development of employees.  相似文献

The Convention on the rights of the child has not made much of a difference to the existing conditions of children in India. Moral energy and a socio‐political vision is required by not only the government, but all concerned to improve the status of the child in India. There is a need to focus on child rights issues related to creating public awareness, attitudinal change, political commitment, mass sensitisation and reaching the unreached. An appropriate action strategy is suggested for the restoration of the rights of children in India.  相似文献
