ABSTRACT
This study highlights the appropriateness of innovation management principles to successfully manage radical change in the e-commerce industry during the COVID-19 period. The study focuses on transforming delivery platforms in the context of popular e-commerce organizations in the U.A.E. We conducted the study through interviews, and the results reflect the development of three major themes (shifting consumer behavior, implementation of innovation, and innovation for effective change management) since the beginning of the COVID-19 pandemic. During the transition stage, critical aspects concerning product delivery have emerged to stabilize logistics performance with sustainability. The study suggests that firms need to be faster and more flexible to address the market uncertainty through innovative practices. Similar organizations can use this study to develop mechanisms to improve their delivery systems. Additionally, the study also argues that collaborative innovation significantly contributes to the enhancement of consumers' well-being and boosts economic growth.
ABSTRACT
Background and objectives: Coronavirus disease 2019 (COVID-19) is a pandemic caused by SARS-CoV-2 virus that has taken a toll on people all over the world. Previous studies have demonstration association of ABO blood groups with increased susceptibility to various conditions such as infection with Helicobacter pylori, Hepatitis B virus and Norwalk virus and even SARS-CoV1. In this cross-sectional study, we investigated the association between ABO blood groups and COVID-19 in a tertiary care hospital in western Uttar Pradesh, India. Methods: The study included data from 500 SARSCoV-2-positive patients who were referred to the hospital. Diagnosis of COVID-19 was made using RT-PCR. Data including demographic information, comorbidities, ABO blood group, Rh factor, clinical severity as well as the need for assisted ventilation, ICU admission and plasma therapy were collected from patients’ medical records. The Pearson’s correlation, chi square and Fischer exact tests were used to analyze data at significance of 0.05. Results: Frequency of COVID-19 was highest in blood group B (34.8%) and lowest in blood group AB (11.2%). Furthermore, patients with blood group A had significantly more severe form of COVID-19 when compared to patients with other blood groups. The frequency of ICU admission, assisted ventilation and plasma therapy was significantly higher in patients with blood group A than in patients with other blood groups. Conclusion: Our results suggest that patients with blood group A are at higher risk of developing severe COVID-19 infection that may require assisted ventilation and ICU admission. Hence, these patients might require more vigilant surveillance and aggressive treatment measures. Further studies are required to validate these findings.

ABSTRACT
INTRODUCTION: Coronavirus disease 2019 (COVID-19) caused by SARS-CoV2 can present from mild flu-like symptoms to acute respiratory distress syndrome. There is multi-organ involvement; particularly, hematopoietic system can be associated with morphological changes in blood cells of COVID-19 patients. METHOD: We conducted a cross-sectional study on a cohort of 50 COVID-19 patients, confirmed on RT-PCR with documented cycle threshold (Ct) value. Peripheral blood sample of these patients was collected and examined for complete blood counts (CBC) on automated haematological analyser as well as Leishman-stained blood smears to look for morphological changes in blood cells. Morphological changes were evaluated with reference to clinical severity and Ct value. Additionally, association between Ct value and clinical severity was also performed. Statistical tests were performed, and P value <.05 was considered significant. RESULTS: Mean age of our study group was 42.16 ± 15.55 years, with male preponderance. Most commonly observed peripheral blood changes were hypolobation (P value = .002) and toxic granules (P value = .005) in neutrophils, atypical granules with nucleolar prominence in lymphocytes, cytoplasmic granulation with clumped nuclear chromatin in monocytes, giant platelets and thrombocytopenia and normocytic normochromic anaemia. CONCLUSION: No association was found between clinical severity and Ct value as well as peripheral blood morphological changes with Ct value. We conclude that examination of peripheral smear coupled with complete blood count (CBC) is only partially supportive of disease pathogenesis and to assess the viral load other parameters should be utilised instead of relying solely on Ct value.
