ABSTRACT
Introduction: COVID-19 is now deemed as the global health burden. As of 24 july 2022, over 567million confirmed cases and over 6.3 million deaths have been reported. Symptoms include fever, cough, fatigue, body ache and shortness of breath, acute respiratory distress syndrome (ARDS). Vitamin C (ascorbic acid) is a water-soluble vitamin that plays a major role as antioxidant and as co-factor of various biosynthetic pathways in the immune system. Objective(s): In this study we aimed to summarize the current evidence regarding the use of vitamin C in the prevention or treatment of patients with SARS-CoV2 infection, based on available publications between January 2020 and July 2022. Material(s) and Method(s): In this comprehensive literature review two electronic databases (PubMed and EMBASE) were searched from 1 January 2020 to 1 July 2022. Result(s): Numerous researchers and clinicians hypothesised that ascorbic acid could help prevent SARS-CoV-2 infection by boosting immune response and reducing the severity of the viral-mediated inflammatory response. Preliminary observational studies indicate low vitamin C status in critically ill patients with COVID-19. Conclusion(s): While some studies have found no correlation between vitamin intake and mortality, others have discovered that this vitamin c is beneficial in lowering the death rate. In summary, vitamin C possesses positive impacts on curing of infection and this may play a protective role in the current COVID-19 pandemic through boosting the immune system.
ABSTRACT
Introduction: Corona virus disease (COVID-19) was declared as a Pandemic by WHO on March 11, 2020. Since health care workers play an important role in providing care to infected patients, they are exposed to unprecedented levels of risk. At the initial phase of this pandemic, no definitive treatment was available, the only way to combat this disease was prevention. A number of prophylactic drugs were being studied during that time for use by health care workers. On 23rd March 2020, Government of India issued recommendation through National Task Force for Covid-19, for using Hydroxychloroquine as prophylaxis for SARS COV-2. Preclinical studies of Azithromycin have shown immunomodulation and in vitro activity against SARS-COV-2, that has led to its widespread usage during COVID-19. Ivermectin, an antiparasitic drug was reported to have an in vitro activity against SARS-COV-2. This orally administered drug was included in India's revised National COVID-19 treatment protocol for people with mild infection. Vitamin C, a water soluble vitamin has been considered for potential beneficial effects in COVID-19 disease. Many animal studies have indicated that a daily intake of vitamin C may prevent infections. Aim(s): To evaluate the pattern of drugs (HCQ, AZITHROMYCIN, IVERMECTIN,and VITAMIN C) used for COVID-19 prophylaxis among health care workers at GMC, Srinagar. MATERIALS AND METHODS: This study is being conducted by using a survey questionnaire. A survey questionnaire in English has been developed after literature review. The responses will be analyzed using descriptive statistics of frequency and percentage.
ABSTRACT
Aim: The purpose of the present research was to evaluate the co-relation of RTPCR and HRCT chest findings in COVID-19 patients in tertiary care centre. Methodology: In our study, COVID-19 patients with positive RT-PCR results (RT-PCR (+) group) and patients with clinical suspicion of COVID-19 but negative RT-PCR results (RT-PCR (−) group) were compared in terms of CT findings. In CT images, ground-glass opacity and ground-glass opacity + patchy consolidation were the most common lesion patterns in both groups. Results: No statistically significant differences in the rates and types of lesion patterns were observed between the two groups. In both groups, lesion distributions and distribution patterns were similarly frequent in the bilateral, peripheral, and lower lobe distributions. Among the 39 patients who underwent follow-up CT imaging in the first or second month, a regression in lesion number and density was detected in 18 patients from both groups. Conclusion: Due to the false-negative rate of RT-PCR tests caused by various reasons, clinically suspected COVID19 patients with a contact history should be examined with CT scans, even if RT-PCR tests are negative. If the CT findings are positive, these patients should not be removed from isolation.
ABSTRACT
Objective: COVID-19 has affected millions of people throughout the world and due to the high rate of its spread, it is very vital to protect the people who are at the frontlines of COVID-19 positive cases. In this study, we have analyzed the level of awareness among the Healthcare Workers (HCWs) and level of preparedness by the Healthcare Authorities (HCA) for the safety of HCWs. Study Design: Cross-sectional prospective study. Subjects and Methods: Study was conducted online, for 3 months, from July to September 2020, at various Health Care Facilities (HCF) of Sindh, Pakistan. The survey instrument was circulated among the HCWs and a total of 419 filled forms were received and analyzed using SPSS 24. Results: Out of 419 participants, 54.4% were male and 45.6% female. Half of the respondents were doctors (50.1%) with majority having 1-5 years (61.6%) of experience. It was found that the major sources of information of HCWs about COVID-19 was social media (80.4%) and only 18.6% of HCWs had trainings to deal with pandemics. HCA couldn't manage to maintain adequate supply of personal protective equipment (PPE) as goggle/eye shields were available only to 20.5% HCWs, shoe covers to 24.3%, N95 masks to 28.5%. Conclusion: We identified serious concern in the source of information but despite that the knowledge and awareness level was quite acceptable among our study respondents. However, greater efforts to be taken for training campaigns for HCWs as well as supply of PPE.
