COVID-19 pandemic, the foodservice industry has had to modify the way it offers its services. The aim of this paper is to examine the drivers of intention to use and recommendation of online food delivery (OFD) using the SOR model, to analyze the perceived risk of COVID-19 and its relationship with the perceived risk for online purchase of OFD as well as to analyze the cultural effect between Spain and India. For this purpose, an online questionnaire was developed by obtaining a sample of 422 users and structural equation modeling (PLS-SEM) was used to determine which variables had a significant influence on the adoption of the OFD. The results confirm that attitude is the main antecedent of intention to use and recommendation, in contrast to the subjective norm relationships, where it was only confirmed by recommendation. This finding demonstrates how individuals' attitude toward intention and recommendation is more favorable than influence of third parties on decisions.

The recent coronavirus disease (COVID-19) outbreak in Wuhan, China, has led to millions of infections and the death of approximately one million people. No targeted therapeutics are currently available, and only a few efficient treatment options are accessible. Many researchers are investigating active compounds from natural plant sources that may inhibit COVID-19 proliferation. Flavonoids are generally present in our diet, as well as traditional medicines and are effective against various diseases. Thus, here, we reviewed the potential of flavonoids against crucial proteins involved in the coronavirus infectious cycle. The fundamentals of coronaviruses, the structures of SARS-CoV-2, and the mechanism of its entry into the host's body have also been discussed. In silico studies have been successfully employed to study the interaction of flavonoids against COVID-19 Mpro, spike protein PLpro, and other interactive sites for its possible inhibition. Recent studies showed that many flavonoids such as hesperidin, amentoflavone, rutin, diosmin, apiin, and many other flavonoids have a higher affinity with Mpro and lower binding energy than currently used drugs such as hydroxylchloroquine, nelfinavir, ritonavir, and lopinavir. Thus, these compounds can be developed as specific therapeutic agents against COVID-19, but need further in vitro and in vivo studies to validate these compounds and pave the way for drug discovery.

Microbes are a huge contributor to people's health around the world since they produce a lot of beneficial secondary metabolites. Cyanobacteria are photosynthetic prokaryotic bacteria cosmopolitan in nature. Adaptability of cyanobacteria to wide spectrum of environment can be contributed to the production of various secondary metabolites which are also therapeutic in nature. As a result, they are a good option for the development of medicinal molecules. These metabolites could be interesting COVID-19 therapeutic options because the majority of these compounds have demonstrated substantial pharmacological actions, such as neurotoxicity, cytotoxicity, and antiviral activity against HCMV, HSV-1, HHV-6, and HIV-1. They have been reported to produce a single metabolite active against wide spectrum of microbes like Fischerella ambigua produces ambigols active against bacteria, fungi and protozoa. Similarly, Moorea producens produces malygomides O and P, majusculamide C and somocystinamide which are active against bacteria, fungi and tumour cells, respectively. In addition to the above, Moorea sp. produce apratoxin A and dolastatin 15 possessing anti cancerous activity but unfortunately till date only brentuximab vedotin (trade name Adcetris), a medication derived from marine peptides, for the treatment of Hodgkin lymphoma and anaplastic large cell lymphoma has been approved by FDA. However, several publications have effectively described and categorised cyanobacterial medicines based on their biological action. In present review, an effort is made to categorize cyanobacterial metabolites on the basis of their phycochemistry. The goal of this review is to categorise cyanobacterial metabolites based on their chemical functional group, which has yet to be described.

The present study aims to assess the intention of the older population to use healthcare wearable devices (HWDs) for wellness during life-threatening situations like COVID-19. The target population for the study was senior citizens (individuals aged above 60) living in Delhi and the national capital region. The respondents were aware that smartwatches could be used to monitor their health. Data from 534 respondents was collected using a structured questionnaire and nonprobability-based sampling method. The partial least squares structure equation model (PLS-SEM) was used to test the hypothesized model derived from the protection motivation theory (PMT) and constructs from previous studies on HWDs. Healthcare wearables offer new perspectives for gauging both health and technology-related dimensions. The present study is important as unlike existing studies, it discusses not only the utilitarian characteristics of HWDs but also their health-protective dimensions, which are crucial in times of life-threatening situations such as the COVID-19 pandemic. The findings indicate that there is a significant impact of both the protective and utilitarian dimensions of HWDs. The study assesses the perceived vulnerability and severity of the older population in COVID 19 and the intention to use HWDs to handle such health crises. The study confirms that perceived usefulness and information accuracy of HWDs, as well as self-efficacy, perceived severity, and perceived vulnerability of senior citizens are high during the COVID-19 pandemic, which significantly influences their intention to use HWDs.

BACKGROUND: Unintended pregnancies have a negative impact on the health and economy of a nation, which can be prevented by effective family planning (FP) services. Postpartum intrauterine device (PPIUCD) is a safe and effective FP method which allows women to obtain long-acting contraception before discharge from the point of delivery. We observed poor coverage of deliveries with PPIUCD at our facility. This was the trigger to initiate a quality improvement (QI) initiative to increase the PPIUCD coverage from current rate of 4.5%-10% in 3-month period. METHOD: A fishbone analysis of the problem was done and the following causes were identified: lack of focused counselling for FP, lack of sensitisation and training of resident doctors and inconsistent supply of intrauterine contraceptive devices (IUCDs). A QI team was constituted with representatives from faculty members, residents, interns, nursing officers and FP counsellors. The point of care quality improvement methodology was used. INTERVENTIONS: Daily counselling of antenatal women was started by the counsellors and interns in antenatal wards. A WhatsApp group of residents was made initially to sensitise them; and later for parking of problems and trouble shooting. The residents were provided hands-on training at skills lab. Uninterrupted supply of IUCDs was ensured by provision of buffer stock of IUCDs with respective store keepers. RESULT: The PPIUCD insertion rates improved from 4.5% to 19.2% at 3 months and have been sustained to a current 30%-35% after 1 ½ years of initiation of the project tiding through the turbulence during the COVID-19 pandemic using QI techniques. CONCLUSION: Sensitisation and training of residents as well as creation of awareness among antenatal women through targeted counselling helped improve PPIUCD coverage at the facility. QI initiatives have the potential to facilitate effective implementation of the FP programmes by strategic utilisation of the resources.

Catatonic patients may develop deep vein thrombosis (DVT) and pulmonary embolism (PE) due to prolonged periods of immobility. These life-threatening conditions demand prompt recognition and management. We describe the case of a patient with catatonia who presented to anesthesia for electroconvulsive therapy (ECT) at the outset of the current coronavirus disease 2019 pandemic. She complained of breathing difficulty and was suspected to have COVID-19 infection. On further evaluation, she was found to have DVT and PE and required oxygen therapy and intensive care management. The diagnostic delay in our patient would have probably not occurred, had it not been for the existing pandemic situation.

The outbreak of COVID-19 affected the lives of all sections of society as people were asked to self-quarantine in their homes to prevent the spread of the virus. The lockdown had serious implications on mental health, resulting in psychological problems including frustration, stress, and depression. In order to explore the impacts of this pandemic on the lives of students, we conducted a survey of a total of 1182 individuals of different age groups from various educational institutes in Delhi - National Capital Region (NCR), India. The article identified the following as the impact of COVID-19 on the students of different age groups: time spent on online classes and self-study, medium used for learning, sleeping habits, daily fitness routine, and the subsequent effects on weight, social life, and mental health. Moreover, our research found that in order to deal with stress and anxiety, participants adopted different coping mechanisms and also sought help from their near ones. Further, the research examined the student's engagement on social media platforms among different age categories. This study suggests that public authorities should take all the necessary measures to enhance the learning experience by mitigating the negative impacts caused due to the COVID-19 outbreak.

Disposable filtering face piece respirators (FFRs) are usually not approved for routine practice of decontamination and reuse. However, such practice of decontamination and reuse may be needed only as a crisis capacity strategy to ensure continued availability. The current severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic would help us enlighten about more effective and efficient ways of decontamination and reuse. Based on the limited research available, ultraviolet irradiation, vapors of hydrogen peroxide, and moist heat showed the most promising potential methods to decontaminate FFRs. This article summarizes available research about decontamination of FFRs before reuse. How to cite this article: Singh R, Azim A, Singh N. Should We or Should We Not Reuse Filtering Face Piece Masks? A Review. Indian J Crit Care Med 2020;24(9):857-862.

COVID-19 has forsaken the world because of extremely high infection rates and high mortality rates. At present we have neither medicine nor vaccine to prevent this pandemic. Lockdowns, curfews, isolations, quarantines, and social distancing are the only ways to mitigate their infection. This is badly affecting the mental health of people. Hence, there is an urgent need to address this issue. Coronavirus disease 2019 (COVID-19) is caused by a novel Betacorona virus named SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) which has emerged in the city of Wuhan in China and declared a pandemic by WHO since it affected almost all the countries the world, infected 24,182,030 people and caused 825,798 death as per data are compiled from John Hopkins University (JHU). The genome of SARS-CoV-2 has a single-stranded positive (+) sense RNA of ∼30 kb nucleotides. Phylogenetic analysis reveals that SARS-CoV-2 shares the highest nucleotide sequence similarity (∼79 %) with SARS-CoV. Envelope and nucleocapsids are two evolutionary conserved regions of SARS-CoV-2 having a sequence identity of about 96 % and 89.6 %, respectively as compared to SARS-CoV. The characterization of SARS-CoV-2 is based on polymerase chain reaction (PCR) and metagenomic next-generation sequencing. Transmission of this virus in the human occurs through the respiratory tract and decreases the respiration efficiency of lungs. Humans are generally susceptible to SARS-CoV-2 with an incubation period of 2-14 days. The virus first infects the lower airway and bind with angiotensin-converting enzyme 2 (ACE2) of alveolar epithelial cells. Due to the unavailability of drugs or vaccines, it is very urgent to design potential vaccines or drugs for COVID-19. Reverse vaccinology and immunoinformatic play an important role in designing potential vaccines against SARS-CoV-2. The suitable vaccine selects for SARS-CoV-2 based on binding energy between the target protein and the designed vaccine. The stability and activity of the designed vaccine can be estimated by using molecular docking and dynamic simulation approaches. This review mainly focused on the brief up to date information about COVID-19, molecular characterization, pathogen-host interaction pathways involved during COVID-19 infection. It also covers potential vaccine design against COVID-19 by using various computational approaches. SARS-CoV-2 enters brain tissue through the different pathway and harm human's brain and causes severe neurological disruption.
