A Systematic Review and Meta-Analysis on the Efficacy of Curcumin/Turmeric for the Prevention and Amelioration of Radiotherapy/Radiochemotherapy Induced Oral Mucositis in Head and Neck Cancer Patients.

BACKGROUND: Oral Mucositis(OM) is an acute debilitating dose limiting toxicity of Radiotherapy/Radiochemotherapy(RT/RCT) in management of Head and Neck Cancer (HNC). Curcumin/Turmeric may reduce OM in patients. AIM: Efficacy of Curcumin/Turmeric for preventing and ameliorating the onset and severity of RT/RCT induced OM was analysed in this review. METHODS: A systematic literature search with meta-analysis were performed using Mesh terms in PubMed, Google scholar, Science Direct, Cochrane library and manual searching, articles published from 2010 to April 2021 were included. Clinical trials that studied the efficacy/effects of turmeric / curcumin in management of RT/RCT induced OM in HNC patients were included. Statistical Analysis were done to calculate the pooled Risk ratio at 95%confidence interval with significance at p.

Negotiated Sharing of Pandemic Data, Models, and Resources.

Urgent responses to the COVID-19 pandemic depend on increased collaboration and sharing of data, models, and resources among scientists and researchers. In many scientific fields and disciplines, institutional norms treat data, models, and resources as proprietary, emphasizing competition among scientists and researchers locally and internationally. Concurrently, long-standing norms of open data and collaboration exist in some scientific fields and have accelerated within the last two decades. In both cases-where the institutional arrangements are ready to accelerate for the needed collaboration in a pandemic and where they run counter to what is needed-the rules of the game are "on the table" for institutional-level renegotiation. These challenges to the negotiated order in science are important, difficult to study, and highly consequential. The COVID-19 pandemic offers something of a natural experiment to study these dynamics. Preliminary findings highlight: the chilling effect of politics where open sharing could be expected to accelerate; the surprisingly conservative nature of contests and prizes; open questions around whether collaboration will persist following an inflection point in the pandemic; and the strong potential for launching and sustaining pre-competitive initiatives.
