ABSTRACT
Background: The pathophysiology of viral-infections is highly complex and involves host immunocompetence, host genetics, and gene-environment interactions. We hypothesized that polymorphic variants in host genes, blood group and previous vaccination status against H1N1 may affect the clinical course of covid-19 infection. Method(s): A total of 202 subjects who were RT-PCR negative after Covid-19 infection were recruited. We investigated association between Covid-19 infection (Severity and recovery period) and multiple factors including ABO and Rh blood groups, H1N1 vaccination, polymorphism in Viral susceptibility genes (ACE2 G8790A), and polymorphism in host response genes (ACE I/D rs4646994, IL6- 174G/C, GSTT1/GSTM1 I/D and GSTP1 Ile 105 Val). Result(s): B-ve and O-ve ABO and Rh blood groups had significantly higher Covid-19 recovery period applied on one-vs.-all in a nonparametric t-test (p<0.05). Subjects who had vaccinated themselves against H1N1 presented with a lower recovery-period (p<0.05). Both variables (blood group and H1N1 vaccination) were not however associated with Covid-19 severity. Out of the studied polymorphisms, ACE2 G8790A and GSTT1/GSTM1 were significantly associated with covid-19 infection. Our results indicated that G/G genotype of ACE2 G8790A (OR 3.52, P 0.007) and GSTT1/ GSTM1 null (M1 - / - OR = 3.98, P = 0.0004;T1 - / - OR 3.84, P = 0.004) and double null (M1 - / - /T1 - / - OR = 9.66, P = 0.001) are likely to be associated with an increased risk for severe-critical outcomes in individuals with COVID-19. Other polymorphisms analyzed in this study were found to have no significant association with Covid-19 outcome. Conclusion(s): This study suggests that outcome of Covid-19 infection is affected by both clinical and genetic factors. Thus it seems plausible to utilize these factors as prediction and susceptibility markers in the prognosis of COVID-19, which may help to personalize the treatment.
ABSTRACT
Aim: To examine the effect of remdesivir for treating non-hospitalized patients with COVID-19. Study design: Retrospective study Place and duration of study: Department of Medicine, Bolan Medical College, Quetta from 1st April 2021 to 30th September 2021. Methodology: One hundred patients were enrolled and divided into group A and group B within the age of 24-70 years. Group A was receiving remdesivir while group B is not receiving remdesivir. The clinical variables, BMI, comorbidities, duration of disease severity and viral load were determined. RT-PCR was conducted to determine viral load. Results: The mean age of study participants was 50±15 years with greater number of males. Diabetes was the major comorbidity. The time duration was decreased in group A upto 5 days and 8 days in group B. The viral load was decreased by mean value 6.32±1.76 to 6.2±1.78 in group B then group A respectively. Conclusion: Remdesivir is effective in COVID-19 treatment.
ABSTRACT
This study aims to determine the plans and strategies adopted by the hotel industry during the COVID-19 crisis. In order to conduct this study, a qualitative research methodology was used where semi-structured interviews were conducted from three countries: Austria, Pakistan, and Indonesia. Interviews were conducted online with the help of applications such as Skype, WhatsApp, and Zoom. A thematic analysis was conducted in which codes, categories, and final themes were generated. The final themes are the study's findings, which are strategies for employees, strategies for customers, strategies for SME hotels, and strategies for the staff. Strategies for employees indicate the planning and programs of the SME Hotels. The study's findings show that strategies adopted by the hotel industries vary from country to country while depending on the contextual factors and role of the government. Most Small and Medium Enterprises (SMEs) hotels in developing countries are less familiar with how to react and survive in the conditions of the crises. Thus, this study can benefit the different stakeholders in the developed and developing countries for adopting strategies and maintain their business during the crises of the COVID-19.
