Gender differences in COVID-19 knowledge, risk perception, and public stigma among the general community: Findings from a nationwide cross-sectional study in India.

Introduction: Individual and community characteristics predictive of knowledge, perception, and attitude on COVID-19, specifically on gender, have not been adequately explored. Objective: To examine the gender differences in COVID-19 knowledge, self-risk perception and public stigma among the general community and to understand other socio-demographic factors which were predictive of them. Method: A nationally representative cross-sectional multi-centric survey was conducted among adult individuals(≥18 yrs) from the community member (N = 1978) from six states and one union territory of India between August 2020 to February 2021. The participants were selected using systematic random sampling. The data were collected telephonically using pilot-tested structured questionnaires and were analyzed using STATA. Gender-segregated multivariable analysis was conducted to identify statistically significant predictors (p < 0.05) of COVID-19-related knowledge, risk perception, and public stigma in the community. Results: Study identified significant differences between males and females in their self-risk perception (22.0% & 18.2% respectively) and stigmatizing attitude (55.3% & 47.1% respectively). Highly educated males and females had higher odds of having COVID-19 knowledge (aOR: 16.83: p < 0.05) than illiterates. Highly educated women had higher odds of having self-risk perception (aOR: 2.6; p < 0.05) but lower public stigma [aOR: 0.57; p < 0.05]. Male rural residents had lower odds of having self-risk perception and knowledge [aOR: 0.55; p < 0.05 & aOR: 0.72; p < 0.05] and female rural residents had higher odds of having public stigma [aOR: 1.36; p < 0.05]. Conclusion: Our study findings suggest the importance of considering thegender differentials and their background, education status and residential status in designing effective interventions to improve knowledge and reduce risk perception and stigma in the community about COVID-19.

An insight into the simulation directed understanding of the mechanism in SARS CoV-2 N-CTD, dimer integrity, and RNA-binding: Identifying potential antiviral inhibitors.

Coronavirus 2019 is a transmissible disease and has caused havoc throughout the world. The present study identifies the novel potential antiviral inhibitors against the nucleocapsid C-terminal domain that aids in RNA-binding and replication. A total of 485,629 compounds were screened, and MD was performed. The trajectory analysis (DCCM & PCA), structural integrity, and degree of compaction depicted the protein-ligand complex stability (PDB-PISA and Rgyr). Results obtained from screening shortlists 13 compounds possessing high Docking score. Further, seven compounds had a permissible RMSD limit (3 Å), with robust RMSF. Post-MD analysis of the top two compounds (204 and 502), DCCM & PCA analysis show a positive atomic displacements correlation among residues of active sites-dimer (Chain A and Chain B) & residual clustering. The ΔGint of RNA-bound (-83.5 kcal/mol) and drug-bound N-CTD-204 (-40.8 kcal/mol) and 502(-39.7 kcal/mol) as compared to Apo (-35.95 kcal/mol) suggests stabilization of protein, with less RNA-binding possibility. The Rgyr values depict the loss of compactness on RNA-binding when compared to the drug-bound N-CTD complex. Further, overlapping the protein complexes (0 ns and 100 ns) display significant changes in RMSD of the protein (204-2.07 Å and 502-1.89 Å) as compared to the Apo (1.72 Å) and RNA-bound form (1.76 Å), suggesting strong interaction for compound 204 as compared to 502. ADMET profiling indicates that these compounds can be used for further experiments (in vitro and pre-clinical). Compound 204 could be a promising candidate for targeting the N-protein-RNA assembly and viral replication.

Computational basis of SARS-CoV 2 main protease inhibition: an insight from molecular dynamics simulation based findings.

The coronavirus disease 2019 (COVID-19) pandemic is caused by newly discovered severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). One of the striking targets amongst all the proteins in coronavirus is the main protease (Mpro), as it plays vital biological roles in replication and maturation of the virus, and hence the potential target. The aim of this study is to repurpose the Food and Drug Administration (FDA) approved molecules via computer-aided drug designing against Mpro (PDB ID: 6Y2F) of SARS CoV-2 due to its high x-ray resolution of 1.95 Å as compared to other published Mprostructures. High Through Virtual Screening (HTVS) of 2456 FDA approved drugs using structure-based docking were analyzed. Molecular Dynamics simulations were performed to check the overall structural stability (RMSD), Cα fluctuations (RMSF) and protein-ligand interactions. Further, trajectory analysis was performed to assess the binding quality by exploiting the protein-residue motion cross correlation (DCCM) and binding free energy (MM/GBSA). Tenofovir, an antiretroviral for HIV-proteases and Terlipressin, a vasoconstrictor show stable RMSD, RMSF, better MM/GBSA with good cross correlation as compared to the Apo and O6K. Moreover, the results show concurrence with Nelfinavir, Lopinavir and Ritonavir which have shown significant inhibition in in vitro studies. Therefore, we conclude that Tenofovir and Terlipresssin might also show protease inhibition but are still open to clinical validation in case of SARS-CoV 2 treatment.Communicated by Ramaswamy H.

Impact of COVID-19 on utilization of maternal and child health services in India: Health management information system data analysis.

Background/Objectives: Studies globally have documented the impact of COVID 19 on maternal and newborn health services. This study assesses the impact of COVID-19 on essential maternal and child health (MCH) services in India based on the national Health Management Information System (HMIS). Methods: Present retrospective study used secondary data analysis upon the routinely collected data accessed from Health Management Information System. Microdata on maternal and newborn indicators was extracted for all states between April and June during 2019, 2020 and 2021. Relative change for each indicator were taken into consideration for the year 2020 and 2021; with respect to the outcomes in 2019. Results: Compared to 2019, antenatal care registrations saw a decline in all states for both periods in 2020 and 2021 except for Sikkim, Telangana, Maharashtra and Andhra Pradesh. Similarly, the relative changes in 2019 pertaining to the proportion of pregnant women provided with emergency obstetric care for pregnancy complications registered a decline in all states except for Himachal Pradesh, Telangana and Arunachal Pradesh. There was a decreasing trend noted in institutional deliveries in 2020 and 2021 among all major states. However, an increasing trend was seen in the number of immunization sessions held among all major states. Conclusion: The study demonstrates a disruption in service delivery during the lockdown period in the first wave and the peak of the second wave. Further qualitative studies need to be undertaken to generate evidence for maintaining continuum of care during a pandemic situation.

COVID-19-associated Pulmonary Aspergillosis: A Case Series.

Background: With the development of coronavirus disease-2019 (COVID-19) pandemic, there is also increased risk of multiple secondary infections either disease- or drug-related. It includes many bacterial as well as invasive fungal infections. Patients and methods: There was suspicion of invasive pulmonary aspergillosis (IPA) infection in COVID-19 patients who were critically ill and had acute respiratory distress syndrome (ARDS). We did radiological evaluation and galactomannan assay in these patients. Result: We have diagnosed COVID-19-associated pulmonary aspergillosis (CAPA) in these patients and started antifungal treatment with voriconazole in all of these COVID-19 patients. Conclusion: It is very important to report such cases, so that healthcare professionals and authorities related to healthcare will be aware of and may also prepare for the increasing burden of this complication. We describe a case series of CAPA infection. How to cite this article: Sharma K, Kujur R, Sharma S, Kumar N, Ray MK. COVID-19-associated Pulmonary Aspergillosis: A Case Series.

Challenges in Accessing and Delivering Maternal and Child Health Services during the COVID-19 Pandemic: A Cross-Sectional Rapid Survey from Six States of India.

BACKGROUND/OBJECTIVES: Globally, the COVID-19 pandemic and its prevention and control policies have impacted maternal and child health (MCH) services. This study documents the challenges faced by patients in accessing MCH services, and the experiences of health care providers in delivering those services during the COVID-19 outbreak, explicitly focusing on the lockdown period in India. METHODS: A cross-sectional study (rapid survey) was conducted in 18 districts from 6 states of India during March to June, 2020. The sample size included 540 MCH patients, 18 gynaecologists, 18 paediatricians, 18 district immunisation officers and 108 frontline health workers. Bivariate analysis and multivariable analysis were used to assess the association between sociodemographic characteristics, and challenges faced by the patients. RESULTS: More than one-third of patients (n = 212; 39%) reported that accessing MCH services was a challenge during the lockdown period, with major challenges being transportation-related difficulties (n = 99; 46%) unavailability of hospital-based services (n = 54; 23%) and interrupted outreach health services (n = 39; 18.4%). The supply-side challenges mainly included lack of infrastructural preparedness for outbreak situations, and a shortage of human resources. CONCLUSIONS/RECOMMENDATIONS: A holistic approach is required that focuses on both preparedness and response to the outbreak, as well reassignment and reinforcement of health care professionals to continue catering to and maintaining essential MCH services during the pandemic.

Virtual screening and molecular dynamics simulation study of approved drugs as a binder to the linoleic acid binding site on spike protein of SARS-CoV-2 and double mutant (E484Q and L452R).

INTRODUCTION: Binding of linoleic acid (LA) to the spike trimer stabilizes it in closed conformation hindering its binding to angiotensin-converting enzyme-2, thus decreasing infectivity. In the current study, we tend to repurpose Food and Drug Administration-approved drugs as binder to the LA binding pocket in wild and double mutant spike protein. MATERIALS AND METHODS: Approved drugs from DrugBank database (n = 2456) were prepared using Ligprep module of Schrodinger. Crystal structure of LA bound to spike trimer was retrieved (PDB: 6ZB4) and prepared using protein preparation wizard and grid was generated. A virtual screening was performed. With the help of molecular dynamics (MD) studies interaction profile of screened drugs were further evaluated. The selected hits were further evaluated for binding to the double mutant form of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). RESULTS AND DISCUSSION: Following virtual screening, a total of 26 molecules were shortlisted, which were further evaluated using 1ns MD simulation study. Four ligands showing better root mean square deviation (RMSD), RMSD to LA with interaction profile similar to LA were further evaluated using 100 ns MD simulation studies. A total of 2 hits were identified, which performed better than LA (selexipag and pralatrexate). Both these ligands were also found to bind to LA binding site of the double mutant form (E484Q and L452R); however, the binding affinity of pralatrexate was found to be better. CONCLUSION: We have identified 2 ligands (selexipag and pralatrexate) as possible stable binders to the LA binding site in spike trimer (wild and mutant form). Among them, pralatrexate has shown in vitro activity against SARS-CoV-2, validating our study results.

Modeling a COVID-19 Vaccination Campaign in the State of Madhya Pradesh, India.

COVID-19 vaccination campaigns have been launched across the globe to mitigate the impact of the COVID-19 disease. However, COVID-19 vaccination campaigns (Vaccination campaigns are the complete process of COVID-19 vaccination campaigns beyond just administrating vaccines.) are a complex multi-stakeholder process, and therefore, it is important to understand the key components and drivers of vaccination campaigns to help devise strategies to increase vaccination coverage for existing and future vaccination efforts. A system dynamics modeling approach was used to trace the vaccination campaign for the Indian state of Madhya Pradesh. The results identified the key stakeholders of the vaccination campaign and their inter-linkages, and the diverse perspectives of stakeholders of vaccination campaigns in Madhya Pradesh were collated in a structured format. Further, system dynamics models were developed to capture all aspects of the vaccination campaign in Madhya Pradesh, including the challenges and innovations. The outcomes of the study can assist academicians, practitioners, and policymakers develop vaccination programs at sub-national, national, and global levels. They will guide decision-makers to take preemptive measures to mitigate possible risks and challenges and provide improved services as part of vaccination campaigns.

Development & validation of scales to assess stigma related to COVID-19 in India.

Background & objectives: COVID-19 pandemic has triggered social stigma towards individuals affected and their families. This study describes the process undertaken for the development and validation of scales to assess stigmatizing attitudes and experiences among COVID-19 and non-COVID-19 participants from the community. Methods: COVID-19 Stigma Scale and Community COVID-19 Stigma Scale constituting 13 and six items, respectively, were developed based on review of literature and news reports, expert committee evaluation and participants' interviews through telephone for a multicentric study in India. For content validity, 61 (30 COVID-19-recovered and 31 non-COVID-19 participants from the community) were recruited. Test-retest reliability of the scales was assessed among 99 participants (41 COVID-19 recovered and 58 non-COVID-19). Participants were administered the scale at two-time points after a gap of 7-12 days. Cronbach's alpha, overall percentage agreement and kappa statistics were used to assess internal consistency and test-retest reliability. Results: Items in the scales were relevant and comprehensible. Both the scales had Cronbach's α above 0.6 indicating moderate-to-good internal consistency. Test-retest reliability assessed using kappa statistics indicated that for the COVID-19 Stigma Scale, seven items had a moderate agreement (0.4-0.6). For the Community COVID-19 Stigma Scale, four items had a moderate agreement. Interpretation & conclusions: Validity and reliability of the two stigma scales indicated that the scales were comprehensible and had moderate internal consistency. These scales could be used to assess COVID-19 stigma and help in the development of appropriate stigma reduction interventions for COVID-19 infected, and mitigation of stigmatizing attitudes in the community.

Factors associated with COVID-19 stigma during the onset of the global pandemic in India: A cross-sectional study

Objective To assess factors associated with COVID-19 stigmatizing attitudes in the community and stigma experiences of COVID-19 recovered individuals during first wave of COVID-19 pandemic in India. Methods A cross-sectional study was conducted in 18 districts located in 7 States in India during September 2020 to January 2021 among adults > 18 years of age selected through systematic random sampling. Data on socio demographic and COVID-19 knowledge were collected from 303 COVID-19 recovered and 1,976 non-COVID-19 infected individuals from community using a survey questionnaire. Stigma was assessed using COVID-19 Stigma Scale and Community COVID-19 Stigma Scale developed for the study. Informed consent was sought from the participants. Univariate and multivariate binary logistic regression analysis were conducted. Results Half of the participants (51.3%) from the community reported prevalence of severe stigmatizing attitudes toward COVID-19 infected while 38.6% of COVID-19 recovered participants reported experiencing severe stigma. Participants from the community were more likely to report stigmatizing attitudes toward COVID-19 infected if they were residents of high prevalent COVID-19 zone (AOR: 1.5;CI: 1.2–1.9), staying in rural areas (AOR: 1.5;CI:1.1–1.9), belonged to the age group of 18–30 years (AOR: 1.6;CI 1.2–2.0), were male (AOR: 1.6;CI: 1.3–1.9), illiterate (AOR: 2.7;CI: 1.8–4.2), or living in Maharashtra (AOR: 7.4;CI: 4.8–11.3). COVID-19 recovered participants had higher odds of experiencing stigma if they had poor knowledge about COVID-19 transmission (AOR: 2.8;CI: 1.3–6.3), were staying for 6–15 years (AOR: 3.24;CI: 1.1–9.4) in the current place of residence or belonged to Delhi (AOR: 5.3;CI: 1.04–26.7). Conclusion Findings indicated presence of stigmatizing attitudes in the community as well as experienced stigma among COVID-19 recovered across selected study sites in India during the first wave of COVID-19 pandemic. Study recommends timely dissemination of factual information to populations vulnerable to misinformation and psychosocial interventions for individuals affected by stigma.

COVID-19 Vaccination in Solid-Organ Transplant: A Real-World Multicenter Experience.

OBJECTIVES: India ranks third globally in organ procurement and transplant and has the second highest COVID-19 incidence rate, but data regarding COVID-19 vaccination in solid-organ transplant patients are scarce. MATERIALS AND METHODS: We created a cross-sectional, anonymous, online questionnaire and sentinvitations to several transplant centers in India. We surveyed vaccine mandates, immunization coverage and side effects, administration timing, infection severity among solid-organ transplant recipients, and booster dosage recommendations. RESULTS: The survey results showedthat vaccinepolicy is heterogeneous among centers; vaccination is voluntary at some centers (44.7%), but some centers have established COVID-19 vaccination as a requirement for transplant candidates (44.6%). CoviShield was the most common vaccine administered (89.3%), and more than 50% of transplant recipients and donors were fully vaccinated. Survey results showed that the pretransplant wait time after full vaccination (both doses) is 2 to 4 weeks (48.9%), and the optimal time for vaccination after transplant is 3 to 6 months (59.3%). For vaccinated transplant patients, 89.4% of respondents reported an incidence rate for posttransplant breakthrough infection of less than 25%. For unvaccinated patients, 38.3% ofrespondents reported a 25% to 50% incidence rate of posttransplant COVID- 19 infection. Booster doses are recommended at many transplant centers in India, as reported by 89.4% of survey respondents. CONCLUSIONS: The results of the survey suggested that there are no substantial safety concerns Future targets should include increasing efficacy and increasing booster doses of the COVID-19 vaccine.

Monetary-fiscal coordination: when, why and how?

Purpose This paper aims to revisit the theme of fiscal-monetary coordination in a general equilibrium setup that allows for unconventional monetary policy, monetary policy transmission and developing country characteristics. Design/methodology/approach This paper uses a calibrated new Keynesian dynamic stochastic general equilibrium (DSGE) model to study fiscal-monetary interaction. Findings Debt sits at the center of monetary-fiscal interaction. Under high-debt conditions, the inflation-output trade-off rises with an increase in the strictness with which monetary policy targets inflation, undermining the standard prescription of strict inflation targeting. At the same time, the transmission of monetary policy is also impeded, due to which unconventional monetary policy becomes more appropriate. The need for coordination among the policies gets enhanced in the presence of borrowing cost channel. While the presence of borrowing cost channel increases the need for policy coordination regardless of the debt situation, features like higher share of non-Ricardian households and weaker monetary policy transmission affect monetary-fiscal interaction to a greater extent under high-debt environment. Originality/value First, this paper uses inflation-output trade-off as a metric, to analyze fiscal-monetary interaction. Second, this paper considers the impact of developing country characteristics (such as a higher share of non-Ricardian households, impeded monetary policy transmission and supply constraints/borrowing cost channel) on fiscal-monetary interaction. Third, the DSGE model developed in this paper incorporates open market operations that could shed light on the role of unconventional monetary policy in the presence of high fiscal deficit and debt, which is particularly relevant in the current context of the COVID-19 pandemic. Fourth, the model also permits an investigation into monetary policy transmission under different debt regimes.

Hesitancy versus acceptability: An observational study for acceptance of COVID-19 vaccine among parents and guardians of children under 17 years age in South East Rajasthan

Background: Vaccination against COVID-19 is necessary to reach herd immunity and essential for mitigating the spread. To establish herd immunity, the immunity generated by natural infection or vaccination must prevent onward transmission, not just clinical disease. However, several studies have shown that achieving herd immunity through natural infection might be difficult. Aims and Objectives: The aim of the study is to enquire about parental acceptability for COVID-19 vaccination for their children, factors affecting acceptability, perceptions for pediatric COVID-19 vaccines. Materials and Methods: We conducted an online questionnaire survey in mode of Google form which was distributed through social media platforms to parents/guardians of children below 17 years of age in months of November and December 2021. The questionnaire had various sections: Socio demographic characteristics, family members and medical history, COVID-19-related history, attitudes toward COVID-19, attitudes toward COVID-19 vaccines, and acceptance of COVID-19 vaccination for their children. Results: The most of the parents (71.77%) were ready to vaccinate their child. Graduated parents were showing maximum acceptance. Variables related to maximum vaccine acceptance include English medium of education, higher income, COVID-19-positive member in family, vaccinated parents/guardians, and vigilant parents/guardians about child COVID vaccination. In case of side effects, 68.05% of responders agreed to follow the professional advice of personal doctor/vaccinator. About 35% of respondents want government to roll out vaccination in a phased manner. About 69% responders are in favor of making hospitals and schools as COVID-19 vaccination center for children. Conclusion: The study found high multifactorial acceptability for pediatric COVID-19 vaccination which should be rolled out in phased manner.

Post-COVID symptoms and health-related quality of life in extended postpartum period

Background: COVID-19 pandemic has remarkable effect not just on physical health, but also on psychological state and overall quality of life (QoL). It affected all the section of community including vulnerable section of pregnant females and children. Aims and Objective: The aim of the study was to assess health-related QoL in recovered COVID-19 positive pregnant females in their extended postpartum period along with insight into prevailing post-COVID symptoms in this population. This was a cross-sectional and questionnaire-based study conducted in Kota, Rajasthan, India. Materials and Methods: This study was conducted on 173 admitted females between March 1, 2021 and June 30, 2021 who were pregnant and contacted COVID-19 infection at any point of their antenatal/intrapartum period. The questionnaire included details related to demographics, symptomatology, hospitalization, oxygen requirement, and ventilator use during the acute disease as well as any symptoms after recovery from acute COVID-19 disease. Patients were contacted during their extended postpartum period and systematically asked about a list of post-COVID-19 symptoms (dyspnea, myalgia, fatigue, anosmia, ageusia, chest pain, cough, mood disturbances, etc.), but they were also free to report any other symptoms that they considered relevant. The health-related QoL was evaluated using the EuroQoL five-dimension five-level questionnaire telephone interview version. In-person interview and telephonic interview methods were arranged for collection of data. Descriptive statistical analysis was done. Results: Among the 173 consented participants, the mean age was 26.3 (±6.6) years, most of them were primiparous (45.66%), admitted with gestational age between 37 and 40 weeks (68.21%), asymptomatic (85.54%) or mildly symptomatic. For symptomatic cases, the most common clinical presentations included fever, cough, and dyspnea. Only 1.16% of symptomatic subjects required ventilator support. For 58.96% patients, hospital stay was less than a week. Mean duration of stay was 5.86 days. However, 87.28% patients required antiviral medications. About 23.70% have various comorbidities among which anemia 7.51% and preeclampsia 6.35% predominated. About 85.55% did not experienced any persistent symptoms after discharge but some of the subjects shown persistent symptoms such as cough, fever, and breathlessness among which persistent cough predominates (7.51%). In relation to post-COVID effects, 82.56% were found asymptomatic while rest 17.44% showed effects such as body ache, insomnia, cough, and loss of taste and smell and depression. Conclusion: COVID-19 pandemic left its sequels both in the form of physical as well as psychological symptoms in extended postpartum period although health-related QoL does not significantly affected by COVID-19 disease during this period.

Seroprevalence of antiSARS-CoV-2 IgG antibodies in children with household exposure to confirm cases of COVID-19 during the second wave of COVID-19 pandemic in Kota, Rajasthan

Background: Weather and the susceptibility of children to SARS-CoV-2 infection is still a debated question particularly in view of important decisions regarding opening schools. Therefore, we planned this cross-sectional analysis of antiSARS-CoV-2 Immunoglobulin-G (IgG) antibodies in children with known household exposure to SARS-CoV-2. This serosurveillance, to find the presence of IgG antibodies among children of probable household exposure of confirmed COVID-19 cases will help in the better understanding of the immune response after COVID-19 infection/exposure. Aims and Objectives: The aim of the study was to investigate the prevalence of anti-SARS-CoV-2 antibodies in children among the families who had confirm case/cases of COVID 19 during the second wave of the COVID-19 pandemic. This study is designed as a cross-sectional serosurveillance study in Kota, Rajasthan India. Materials and Methods: Population-based serosurveillance among children with probable household exposure to confirmed COVID-19 cases who was admitted in Govt. Medical College attached COVID 19 dedicated hospital was carried out during October 2021 to December 2021 using the COVID IgG Antibody Detection Enzyme-Linked Immunosorbent Assay kits. Seropositivity among children was measured and with various other factors to understand the immunity status among COVID-19 cases. Descriptive statistical analysis done. Results: 156/1285 eligible candidates (19.53%) having a total of 251 household contacts of <17 years age group agreed to participate in study while rest of them refused. Anti-SARSCoV-2 IgG antibodies were present in 127/251 household contacts (50.59%). Among them maximum 28.68% of seropositive were from age group 11–17 years age, symptoms were observed in 29.13% IgG positive contacts, maximum seropositivity was seen when only one family member was hospitalized, 63% seropositivity was seen when primary relative of child was hospitalized as compared to secondary. Maximum seroreactivity (55.9%) was seen when the Chest CT score of index case was high, that is, 14–25. max reactivity was observed 76/127 (59.84%) when hospital duration of index case is <1 week. 118/127 (92.91%) of seroreactive children were found when the index case was unvaccinated or partially vaccinated. Conclusion: Seropositivity of 50.59% suggests that all the cases may not have IgG antibodies. Among the seronegative cases, the antibodies either not developed, or are undetectable, or have disappeared during the post COVID period. Seropositivity based on gender difference is statistically not significant. Proportion of positivity shows an increasing trend with increasing age among pediatric household contacts. Complete COVID-19 vaccination is an effective tool to minimize the disease frequency/severity. Severe disease patients with high CT score transmits the infection to household contacts more efficiently.

A dissection of Indian growth using a DSGE filter.

In order to build a strong and sustainable recovery post the COVID-19 pandemic, we need to draw important observations from the growth experience of the past. In this context, this paper uses a dynamic stochastic general equilibrium (DSGE) model that takes into account persistent growth rate shocks to decompose the Indian GDP into potential output and output gap. Apart from analysing the trajectory of potential output-output gap, it also examines their underlying drivers. The results suggest that a combined deceleration in neutral and investment-specific technology growth post 2016, brought down the potential growth to around 6 per cent in 2020Q1. The output gap also witnessed a persistent decline since 2018Q1, primarily due to weak demand and a rise in investment adjustment costs reflecting heightened stress in the investment and financial sectors. A forecasting exercise is also undertaken which shows that the estimates of output gap from the model possess competing inflation forecasting ability compared to HP filtered output gap.

COVID-19-associated rhino-orbital-cerebral mucormycosis: A systematic review, meta-analysis, and meta-regression analysis.

BACKGROUND: Till now, no meta-analysis is available to address the clinical profile, risk factors, different interventions, and outcomes among COVID-19-associated rhino-orbito-cerebral mucormycosis (C-ROCM) cases. MATERIALS AND METHODS: Eight literature databases were screened using appropriate keywords from November 1, 2019, to June 30, 2021. The objectives were to analyze the clinical and microbiological profile, risk factor/comorbidity, intervention, and outcome. "R-metafor package" was used for analysis. RESULTS: A total of 23 studies were included. The mean age of presentation of C-ROCM was 54.6 years. The most common presentation was ptosis (72.7%), lid edema (60.6%), proptosis (60.6%), ophthalmoplegia (57.3%), loss of vision (53.7%), facial edema (34.7%), and nasal-blockage (11.8%). Evidence of intracranial spread was seen in 42.8% of cases. Rhizopus was the most common fungus (57.1%) isolated in fungal culture. Among C-ROCM patients, diabetes was the commonest comorbid condition, and the use of corticosteroids related to COVID-19 treatment was the most common risk factor (85.75%). Compared to controlled diabetics, C-ROCM was significantly higher among uncontrolled diabetics (odds ratio [OR] 0.15, 95% confidence interval [C.I.] 0.041-0.544, P = 0.0010). However, no significant association was seen between C-ROCM and COVID-19 severity (OR 0.930, 95% C.I. 0.212-4.087, P = 0.923). For treatment, amphotericin-B was the most common antifungal drug used which was followed by surgical options. However, mortality was high (prevalence 0.344, 95% C.I. 0.205-0.403) despite treatment. CONCLUSION: Although local rhino-orbito symptoms were the first to appear, rapid intracranial extension was seen in a significant number of C-ROCM cases. Uncontrolled diabetes and excessive use of corticosteroid were the most common risk factors present among the C-ROCM cases. High index clinical suspicion is imperative (specifically among COVID-19 patients with diabetes), and routine screening may be helpful.

Yogic Neti-Kriya Using Povidone Iodine: Can it have a Preventive Role Against SARS-CoV-2 Infection Gateway?

During this COVID-19 pandemic, except steroid, none of the therapeutic measures have showed any evidence of efficacy. Traditionally jala-neti using lukewarm salted water remains a yogic way of maintaining upper airway hygiene. Saline irrigation decreases the concentration of inflammatory mediators (e.g. histamine, leukotriene etc.) in nasal secretions, reduces the severity and frequency of sinusitis, reduce need of antibiotic therapy and restores competency of nasal mucosa. Jala-neti is an integral part of six cleansing techniques of yogic kriyas practised in India since thousands of years. Jala-neti can clean the upper airways, prevents colonization of infectious agents, removes foreign bodies, prevents stasis of mucous and subsequently enhances the drainage of paranasal sinuses and maintain health. Regular practice of Jala neti improves nasal symptoms and overall health status of patients with sinusitis. Jala-neti sample can even be used for COVID-19 diagnosis. Povidone iodine (PVP-I) has been utilized as a time tested antimicrobial agent with broad spectrum coverage against wide range of bacteria and viruses. Anti-SARS-CoV-2 action of PVP-I was seen at a concentration as low as 0.45%. PVP-I is generally well tolerated upto 5%, however nasal ciliotoxicity is reported at this concentration, however, this toxicity is not reported with lower concentrations(1.25% and 0.5%). So, theoretically, by using neti-kriya with povidone iodine (0.5-1%) as irrigation solution can combine and enhance the protection against COVID-19 and this can be an important armor in the fight against COVID-19. However, this hypothesis needs to be validated in real life clinical trial scenario before implementing.

Update on geographical variation and distribution of SARS-nCoV-2: A systematic review.

Knowledge of a new mutant strain of SARS-coronavirus (CoV-2) is enormously essential to identify a targeted drug and for the development of the vaccine. In this article, we systematically reviewed the different mutation strains (variant of concern [VOC] and variant of interest [VOI]) which were found in different countries such as the UK, Singapore, China, Germany, Vietnam, Western Africa, Dublin, Ireland, Brazil, Iran, Italy, France, America, and Philippines. We searched four literature databases (PubMed, EMBASE, NATURE, and Willey online library) with suitable keywords and the time filter was November 2019 to June 16, 2021. To understand the worldwide spread of variants of SARS-CoV-2, we included a total of 27 articles of case reports, clinical and observational studies in the systematic review. However, these variants mostly spread because of their ability to increase transmission, virulence, and escape immunity. So, in this paper is we found mutated strains of SARS-CoV-2 like VOCs that are found in different regions across the globe are ALPHA strain in the U.K, BETA strain in South Africa, GAMMA strain in Brazil, Gamma and Beta strains in European Countries, and some VOIs like Theta variant in the Philippines.

Efficacy and safety of dihydroorotate dehydrogenase (DHODH) inhibitors "leflunomide" and "teriflunomide" in Covid-19: A narrative review.

Dihydroorotate dehydrogenase (DHODH) is rate-limiting enzyme in biosynthesis of pyrimidone which catalyzes the oxidation of dihydro-orotate to orotate. Orotate is utilized in the biosynthesis of uridine-monophosphate. DHODH inhibitors have shown promise as antiviral agent against Cytomegalovirus, Ebola, Influenza, Epstein Barr and Picornavirus. Anti-SARS-CoV-2 action of DHODH inhibitors are also coming up. In this review, we have reviewed the safety and efficacy of approved DHODH inhibitors (leflunomide and teriflunomide) against COVID-19. In target-centered in silico studies, leflunomide showed favorable binding to active site of MPro and spike: ACE2 interface. In artificial-intelligence/machine-learning based studies, leflunomide was among the top 50 ligands targeting spike: ACE2 interaction. Leflunomide is also found to interact with differentially regulated pathways [identified by KEGG (Kyoto Encyclopedia of Genes and Genomes) and reactome pathway analysis of host transcriptome data] in cogena based drug-repurposing studies. Based on GSEA (gene set enrichment analysis), leflunomide was found to target pathways enriched in COVID-19. In vitro, both leflunomide (EC50 41.49 ± 8.8 µmol/L) and teriflunomide (EC50 26 µmol/L) showed SARS-CoV-2 inhibition. In clinical studies, leflunomide showed significant benefit in terms of decreasing the duration of viral shredding, duration of hospital stay and severity of infection. However, no advantage was seen while combining leflunomide and IFN alpha-2a among patients with prolonged post symptomatic viral shredding. Common adverse effects of leflunomide were hyperlipidemia, leucopenia, neutropenia and liver-function alteration. Leflunomide/teriflunomide may serve as an agent of importance to achieve faster virological clearance in COVID-19, however, findings needs to be validated in bigger sized placebo controlled studies.
