Perception, acceptance, and adverse effects of COVID-19 vaccines: Insights from Indian population.

Background: Vaccination has been pivotal in eradicating numerous infectious diseases. Nonetheless, concerns about the safety and side effects of the COVID-19 vaccine persist. This study aimed to gauge the perceptions and experiences of the Indian population concerning COVID-19 vaccination. Methods: This study was a cross-sectional survey of 313 participants aged 18 and above from diverse regions in India. Data was sourced using an electronic questionnaire disseminated via Google Forms. The survey evaluated demographics, vaccine awareness, attitudes, and side effects post-vaccination with Covishield and Covaxin. Results: 22.6% of participants exhibited vaccine hesitancy; however, 78.3% believed the advantages superseded the risks. Most participants (81.5%) were aware of vaccine side effects. Most of the Indian respondents (97.1%) accepted the COVID-19 vaccine. Post-vaccination, 27.9% experienced adverse effects such as fever, headache, malaise, dizziness, and pain at the local site. Only 1.3% necessitated hospitalization. Conclusion: Our study underscores the dichotomy between vaccine apprehensions and real-world experiences. Although concerns surrounding vaccine safety were prevalent, the majority of the Indian respondents (97.1%) accepted the COVID-19 vaccine, with most experiencing only transient, mild side effects. While 22.6% initially exhibited hesitancy, primarily due to misinformation, the actual experience post-vaccination was largely positive. To further address hesitancy, streamlined vaccine awareness campaigns emphasizing the safety and efficacy of vaccination are essential.

COVID-19: a viewpoint from hepatic perspective.

Coronaviruses as such are known since last century. The name is derived from their shape which has crown (corona) like radiating spikes. The recent one however is a different one from the Coronavirus involved in SARS (2002-2004) and MERS (2012) in being highly infectious. Initially COVID 19 had a high case fatality rate which has now decreased to a significant extent. Many cases of COVID 19 are asymptomatic with a significant number of positive cases developing a triad of fever, breathlessness and GI symptoms. Recent travel increases the probability of infection. The pathogenesis involves ACE 2 receptors. So, it has been found that there are more cases and mortality among hypertensive individuals. Even higher among the people who use ACE inhibitor in comparison to those who use other anti-hypertensive drugs. Treatment is usually symptomatic. Antiviral drugs and vaccines against COVID-19 are being used. Deranged liver enzymes are common in COVID-19, however, serious liver injury is not much documented. Liver injury is either due to disease itself or due to antiviral drugs. Extra care like strict social distancing, avoiding unnecessary contact is needed for those with autoimmune hepatitis, liver cancer and those who are in immunosuppression because of a scheduled or already liver transplant. Further research is definitely needed in this field. The upcoming researches should also focus on liver injuries associated with disease course and derangements arising as side effects of treatment of COVID-19.

The study of serum hsCRP, ferritin, IL-6 and plasma D-dimer in COVID-19: a retrospective study.

OBJECTIVES: The cut off values for serum high sensitivity C-reactive protein (hsCRP), ferritin, interleukin 6 (IL-6) and plasma D-dimer could be of profound help in detecting COVID-19 patients at risk of adverse outcomes. Therefore, the aim of the present study is to determine the cut off values of the serum hsCRP, ferritin, IL-6 and plasma D-dimer in predicting mortality in COVID-19 patients. METHODS: Four hundred RT-PCR confirmed cases of COVID-19 were sub divided into two groups based on their outcome during hospitalisation. Group I consisted of survivors and Group II consisted of non-survivors. The survivors were further divided into three sub-groups: mild, moderate and severe based on the severity of infection. The laboratory data of serum hsCRP, ferritin, IL-6 and plasma D-dimer for all these patients was retrieved from the Medical Record Section of the Hospital. RESULTS: Mean serum hsCRP, ferritin, IL-6 and plasma D-dimer levels were significantly higher in non-survivors as compared to survivors of COVID-19. The levels of these biomarkers correlated with the severity of COVID-19 illness. ROC curve analysis revealed that plasma D-dimer is having a better predictive value as compared to other parameters in predicting mortality in COVID-19. CONCLUSIONS: The serum hsCRP, ferritin, IL-6 and plasma D-dimer levels could be used in risk stratification of COVID-19 patients. The optimum cut off given by the current study could be considered in predicting adverse outcome in these patients. Amongst the many studied biomarkers, plasma D-dimer might be the best early biomarker to predict mortality in COVID-19 patients.

Emotional distress among health professionals involved in care of inpatients with COVID-19: a survey based cross-sectional study.

INTRODUCTION: Health care workers (HCWs) are directly involved in processes linked with diagnosis, management, and assistance of coronavirus disease-19 (COVID-19) patients which could have direct implications on their physical and emotional health. Emotional aspects of working in an infectious pandemic situation is often neglected in favour of the more obvious physical ramifications. This single point assessment study aimed to explore the factors related to stress, anxiety and depression among HCWs consequent to working in a pandemic. MATERIAL AND METHODS: This was a cross-sectional study involving healthcare workers who were working in COVID-19 inpatient ward, COVID-19 screening area, suspect ward, suspect intensive care unit (ICU) and COVID-19 ICU across four hospitals in India. A web-based survey questionnaire was designed to elicit responses to daily challenges faced by HCWs. The questionnaire was regressed using machine-learning algorithm (Cat Boost) against the standardized Depression, Anxiety and Stress Scale - 21 (DASS 21) which was used to quantify emotional distress experienced by them. RESULTS: A total of 156 participants were included in this study. As per DASS-21 scoring, severe stress was seen in ∼17% of respondents. We could achieve an R² of 0.28 using our machine-learning model. The major factors responsible for stress were decreased time available for personal needs, increasing age, being posted out of core area of expertise, setting of COVID-19 care, increasing duty hours, increasing duty days, marital status and being a resident physician. CONCLUSIONS: Factors elicited in this study that are associated with stress in HCWs need to be addressed to provide wholesome emotional support to HCWs battling the pandemic. Targeted interventions may result in increased emotional resilience of the health-care system.

COVID-19 infection in pregnancy: a review of existing knowledge.

The world has been coping up with the grave pandemic of COVID-19 since its inception into the human race in December, 2019. By entering the host through the spike (S) glycoprotein, it paves way for its own survival and multiplication. Respiratory tract being the point of entry causes pulmonary compromise and leads to development of ARDS. Having non-specific clinical features that resemble flu makes the clinical diagnosis much more difficult. Pregnancy being an immunocompromised and a hypercoagulable state is prone to be a high-risk group for COVID-19. This study is an attempt to understand the maternal and fetal outcomes in COVID-19 and the vertical transmissibility of the virus. Evidence suggests that the contribution of COVID-19 is not very significant in maternal morbidity and mortality. However, due to some factors such as the immunological response in the mother, certain complications may arise in the neonate in the post-natal period. No vertical transmission of the virus has been reported yet. However, the management remains crucial as two lives are at stake. Some of the precautionary measures that can be implemented to prevent COVID-19 can be segregation of medical services from that of the general population in settings of outpatient care, inpatient care and labor room care. Also, triaging the patients into low risk, moderate risk and high risk can aid in faster delivery of health-care facilities to the pregnant and the newborn.

The second wave of COVID-19 results in outbreak of mucormycosis: diabetes and immunological perspective.

OBJECTIVES: To evaluate the potential relationship between COVID-19 pandemic and mucormycosis outbreak. METHODS: PubMed, Embase, Cochrane Library and Google Scholar were searched for the term "COVID-19 and mucormycosis" up to May 31, 2021. RESULTS: After the second wave of COVID-19, the mucormycosis outbreak complicates the natural course of COVID-19. COVID-19 patients with uncontrolled diabetes mellitus with diabetic ketoacidosis, excessive glucocorticoid use, prolonged neutropenia, malnutrition and any underlying immunocompromised conditions are at risk of developing mucormycosis. CONCLUSIONS: Hyperglycaemia impairs the motility of phagocytes and also decreases the oxidative and non-oxidative mechanism of killing the causative pathogen. Chronic hyperglycemia also leads to the formation of advanced glycation end-products (AGE), which leads to cross-linking between key proteins of inflammation and connective tissue such as collagen which makes tissue susceptible to immunological dysregulation. The receptor for AGE (RAGE) is expressed on various inflammatory cells including neutrophils and its activation by AGEs leads to activation of many down signaling pathways which ultimately leads to impairment of the inflammatory response. Hyperglycemia also increases serum Nitric Oxide (NO), which decreases neutrophil motility and reduces the synthesis and release of various inflammatory mediators such as TNF-α and IL-1ß, IL-6. It also decreases the expression of adhesion molecules such as LFA-1 and ICAM-2, on neutrophils. Steroids cause immunosuppression majorly by inhibiting the NF-κB pathway which is a transcription factor involved in the synthesis of many immunological mediators such as Interleukins, cytokines, chemokines, etc., and various adhesion molecules.

Human immunodeficiency virus infection amongst newly diagnosed tuberculosis patients and their clinico-radiological profile: A prospective study from Western India.

BACKGROUND: Since time immemorial tuberculosis (TB) has been and continues to be one of the most significant infections causing human disease. In tropical countries, TB remains a leading cause of death. Human immunodeficiency virus (HIV) epidemic continues to fuel this global TB epidemic. The rapid growth of the HIV epidemic in many countries has resulted in an equally dramatic rise in the estimated number of new TB cases, which present therefore the integration of HIV and TB testing at the primary level is need of the hour. METHODS: A prospective study was conducted on newly diagnosed, untreated TB patients aged 15-45 year and patients were screened for HIV infection. Clinico-radiological spectrum of TB among HIV seropositive and seronegative patients was evaluated. RESULTS: Out of a total of 307 patients screened, 17 (5.54%) were found to be HIV seropositive. Seroprevalence was found significantly (P < 0.01, χ2 9.301) more common in 26-35 year age group and higher in Extrapulmonary TB (EPTB) patients than that in pulmonary TB (PTB) patients (9.90% vs 3.4%). Fever was the most common presenting symptom for TB in HIV seropositive patients. On examination pallor (58.82% vs. 15.86%), oral ulcer (35.3% vs. 0.35%) was found more common and on chest X-ray mid-lower zone involvement and mediastinal lymphadenopathy were more common in HIV seropositive patients. CONCLUSION: HIV seropositivity rates among newly diagnosed TB patients aged 15-45 year was 5.54 percent. The presentation of TB was more often atypical among these patients. Thus, an integrated model of TB and HIV at primary healthcare service delivery is an efficient use of resources that would address the two very important co-epidemics and thereby result in better management.

Association of Single Nucleotide Polymorphisms (SNPs) in Genes Encoding for Folate Metabolising Enzymes with Glioma and Meningioma in Indian Population

Background: The association of primary brain tumors with Single Nucleotide polymorphisms (SNPs) in genes of folate metabolising enzymes have been reported to vary among different ethnic population. Here, we have studied the association of SNPs of folate metabolizing genes with the primary brain tumors (glioma and meningioma) in North Indian population. Methods: SNPs of genes coding for folate metabolizing enzymes was carried out in 288 study population from North India [Glioma (n=108), Meningioma (n=76) and healthy-control (n=104)]. The allele-specific polymerase chain reaction (ARMS-PCR) was used to analyse the SNP A1298C of the MTHFR (Methylenetetrahydrofolate-reductase) and the SNP A66G of the methionine synthase reductase (MTRR) genes. The PCR-RLFP (Restriction Fragment Length Polymorphism) was used to analyse the SNP C677T of the Methylene tetrahydrofolate-reductase and the SNP A2756G of the methionine-synthase (MTR) genes. Serum homocysteine, vitamin B12 and folate levels were evaluated in controls/ patients serum using Chemiluminescence immunoassay and the levels were correlated with SNPs genotype. Results: The CC genotype of MTHFR A1298C was observed to have reduced risk of having meningioma than AA genotype (odd ratio=0.62, 95%CI 0.32-0.97, p=0.03). Similarly, the AG genotype of MTRR A66G showed reduced risk of glioma than AA genotype (odd ratio=0.56, 95%CI 0.32-0.97, p=0.039). Furthermore, in patients with AA genotype of MTR A2756G and CT genotype of MTHFR C677T showed higher serum homocysteine level than GG genotype (8.6 µmol/L, p=0.048) and CC genotype (11.2µmol/L, p=0.039) respectively. Conclusion: Our findings provide an insight into the risk association of SNPs in MTHFR A1298C and MTRR A66G genes with glioma/meningioma patients. Further studies are needed to evaluate their clinical implications.
