Leveraging health information helpline to sustain health-care delivery during the COVID pandemic: Experiences from a State in Eastern India.

Background: The unprecedented demands on health-care systems due to the COVID-19 pandemic made countries including India to switch toward alternative modes of health-care delivery. Objectives: The aim of this study was to describe the various COVID-related services delivered through 104 health information helpline (HIHL), located in Jharkhand during the pandemic. Methods: The de-identified secondary data from February 2020 to December 2021 related to COVID services delivered through HIHL were analyzed. Results: There was a significant increase in the COVID call volume during the first as well as the second wave. The HIHL has been able to guide the callers on testing, home isolation and follow-up, home-based teleconsultation, vaccination, timely referral, and support with logistic-related information. Conclusion: The 104 HIHL has played a critical role in sustaining health-care delivery during the pandemic, combating the "infodemic" and guiding the general public by providing authentic information.

Potential of engineered nanostructured biopolymer based coatings for perishable fruits with Coronavirus safety perspectives.

Fresh fruits are prioritized needs in order to fulfill the required health benefits for human beings. However, some essential fruits are highly perishable with very short shelf-life during storage because of microbial growth and infections. Thus improvement of fruits shelf-life is a serious concern for their proper utlization without generation of huge amount of fruit-waste. Among various methods employed in extension of fruits shelf-life, design and fabrication of edible nanocoatings with antimicrobial activities have attracted considerable interest because of their enormous potential, novel functions, eco-friendly nature and good durability. In recent years, scientific communities have payed increased attention in the development of advanced antimicrobial edible coatings to prolong the postharvest shelf-life of fruits using hydrocolloids. In this review, we attempted to highlight the technical breakthrough and recent advancements in development of edible fruit coating by the application of various types of agro-industrial residues and different active nanomaterials incorporated into the coatings and their effects on shelf-life of perishable fruits. Improvements in highly desired functions such as antioxidant/antimicrobial activities and mechanical properties of edible coating to significantly control the gases (O2/CO2) permeation by the incorporation of nanoscale natural materials as well as metal nanoparticles are reviewed and discussed. In addition, by compiling recent knowledge, advantages of coatings on fruits for nutritional security during COVID-19 pandemic are also summarized along with the scientific challenges and insights for future developments in fabrication of engineered nanocoatings.
