ABSTRACT

As countries shore up existing safeguards to address the social and economic impacts of the COVID-19 pandemic, India faces a humanitarian disaster of unprecedented proportions. Ninety per cent of the Indian workforce is employed in the unorganised sector;uncounted millions work in urban areas at great distances from rural homes. When the Government of India (GOI) announced the sudden ‘lockdown' in March to contain the spread of the pandemic, migrant informal workers were mired in a survival crisis, through income loss, hunger, destitution and persecution from authorities policing containment and fearful communities maintaining ‘social distance'. In this context, the article analyses how poverty, informality and inequality are accentuated by the COVID-19 pandemic experiences of ‘locked down' migrant workers. The article examines the nature and scope of existing social policy, designed under changing political regimes and a fluctuating economic climate, to protect this vulnerable group and mitigate dislocation, discrimination and destitution at this moment and in future.

ABSTRACT

INTRODUCTION: COVID-19 usually presents with upper respiratory tract infection in varying severity which can lead to sepsis. Early prediction of sepsis may reduce mortality by timely interventions. The intended purpose of this study was to determine whether the advanced parameters like the extended inflammation parameters (EIPs) can predict prognosis and early progression to sepsis as a sequel of COVID-19 infection and can be used as a screening profile. Also, to evaluate the Intensive Care Infection Score (ICIS) and the COVID-19 prognostic score and validate the scores for our population. METHODS: Prospective observational study of 50 reverse transcription- polymerase chain reaction (RT-PCR) proven admitted COVID-19 patients. The data assessed included complete blood counts (CBC) with EIP measurements, from Day 1 of admission to Day 10. The following groups were studied: noncritical (NC) and critical illness (CI) in COVID-19 positive cases, COVID negative sepsis and nonsepsis cases, and healthy volunteers for reference range. RESULTS: The parameters that showed statistically significant higher mean in CI group compared to the NC group are reactive lymphocyte number and percentage (RE-LYMPH#, RE-LYMPH%), antibody synthesizing lymphocyte number and percentage (AS-LYMPH#, AS-LYMPH%), Reactive monocyte count and percentage (RE-MONO#, RE-MONO%/M), ICIS, COVID-19 prognostic score (p-value <0.05). The AUC confirmed the diagnostic accuracy of all these parameters. From the multivariate logistic regression, the significant risk factor was RE-LYMPH# with cut-off >0.10 (p value: 0.011). CONCLUSION: The new EIP parameters, RE-MONO#, RE-MONO%/M, ICIS score and COVID-19 prognostic score are useful for early prediction of critical illness. AS-LYMPH is the most useful predictor of critical illness on multivariate analysis. RE-MONO# and RE-MONO%/M parameter are useful in distinguishing critical and noncritical non-COVID and COVID-19 patients.

ABSTRACT

SARS-CoV-2 has severely affected capacity in the National Health Service (NHS), and waiting lists are markedly increasing due to downtime of up to 50 min between patient consultations/procedures, to reduce the risk of infection. Ventilation accelerates this air cleaning, but retroactively installing built-in mechanical ventilation is often cost-prohibitive. We investigated the effect of using portable air cleaners (PAC), a low-energy and low-cost alternative, to reduce the concentration of aerosols in typical patient consultation/procedure environments. The experimental setup consisted of an aerosol generator, which mimicked the subject affected by SARS-CoV-19, and an aerosol detector, representing a subject who could potentially contract SARS-CoV-19. Experiments of aerosol dispersion and clearing were undertaken in situ in a variety of rooms with two different types of PAC in various combinations and positions. Correct use of PAC can reduce the clearance half-life of aerosols by 82% compared to the same indoor-environment without any ventilation, and at a broadly equivalent rate to built-in mechanical ventilation. In addition, the highest level of aerosol concentration measured when using PAC remains at least 46% lower than that when no mitigation is used, even if the PAC's operation is impeded due to placement under a table. The use of PAC leads to significant reductions in the level of aerosol concentration, associated with transmission of droplet-based airborne diseases. This could enable NHS departments to reduce the downtime between consultations/procedures.

ABSTRACT

Background At the peak of the coronavirus disease 2019 (COVID-19) pandemic, the need for an orally administered agent to prevent the progression of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection became increasingly evident, which was the impetus behind our investigations with molnupiravir. Molnupiravir has been shown to be effective in preventing hospitalizations and/or clinical complications in patients with mild-to-moderate COVID-19. In this study, we evaluate the efficacy and safety of molnupiravir in Indian patients with mild SARS-CoV-2 infection and at least one risk factor for disease progression (CTRI/2021/05/033739). Methodology This was a phase III, multicenter, randomized, open-label, controlled study conducted in Indian adults aged 18-60 years with mild SARS-CoV-2, reverse transcription polymerase chain reaction (RT-PCR)-positive within 48 hours of enrollment in the study, and within five days of first symptom onset. Enrolled patients were randomized to treatment arms in a 1:1 ratio to receive molnupiravir or placebo in addition to the standard of care (SoC) for SARS-CoV-2 infection. The SoC was in compliance with Government of India guidelines that were in force at the time. The primary endpoint was the rate of hospitalization up to day 14. Safety endpoints included incidence of adverse events (AEs). Results Eligible patients were randomized in a 1:1 ratio to receive molnupiravir in addition to SoC treatment (n = 608) or SoC alone (n = 610). In the molnupiravir group, nine (1.48%) patients required hospitalization versus 26 (4.26%) patients in the control group (risk difference = -2.78%; 95% CI = -4.65, -0.90; p = 0.0053). Overall, 45 (3.70%) patients reported 47 AEs during the study, most of which were mild and resolved completely. The molnupiravir group reported 30 AEs compared to 17 AEs in the control group. Headache and nausea were the two most commonly reported AEs. Conclusions The molnupiravir arm showed a lower rate of hospitalization and a shorter time for the improvement of clinical symptoms coupled with early RT-PCR negativity. Molnupiravir was well tolerated, and AEs were mild and rare. The addition of molnupiravir to standard therapy has the potential to prevent the progression of mild COVID-19 disease to the severe form.

ABSTRACT

Context: Effects of coronavirus disease 2019 (COVID-19) pandemic lockdown on road traffic accidents (RTAs) in Chhattisgarh, India. Background: Most neurosurgical emergencies are from brain and spine trauma. RTA is the leading cause of such injuries. While the nationwide lockdown was an extreme measure to control the COVID pandemic, it influenced the overall road traffic dynamics and neurotrauma. Objective: This study aims to assess the impact of the lockdown on neurotrauma. Methods and Materials: This retrospective study included all patients with brain and spine injuries who were admitted between January 17th and May 31st, 2020. The study population was divided into prelockdown (PL) and lockdown (L) groups. Results: Of the 668 patients, 436 were placed in the PL and 232 in the L group. The mean ages were 36.34 (SD = 17.96) and 35.98 (SD = 16.93), respectively. Male to female ratios were 82.3:17.7 in the PL group and 79.7:20.3 for the L group. RTA-related injuries were significantly lower during the lockdown period (n = 335 PL vs. 162 L [P = 0.048]). During the lockdown, there were more mild injuries (25.91% PL vs. 36.63% L) and less severe injuries (33.25% PL vs. 18.96% L [P = 0.0002]). Mortality was significantly less (P = 0.029) during the lockdown (n = 48 L vs. 124 PL). The proportion of RTA-related neurotrauma cases increased (33.33% L1, 57.14% L2, 73.13% L3, and 80.39% L4) with each phase of lockdown (L1-L4). Conclusions: During the lockdown period, the number of trauma cases had decreased, with a significant decrease in RTA-related admissions, along with their severity and mortality. The number of trauma cases and their severity increased gradually with each phase of lockdown.

ABSTRACT

OBJECTIVE: Interfacility transfers represent a large proportion of neurosurgical admissions to tertiary care centers each year. In this study, the authors examined the impact of the COVID-19 pandemic on the number of transfers, timing of transfers, demographic profile of transfer patients, and clinical outcomes including rates of surgical intervention. METHODS: A retrospective review of neurosurgical transfer patients at a single tertiary center was performed. Patients transferred from April to November 2020 (the "COVID Era") were compared with an institutional database of transfer patients collected before the COVID-19 pandemic (the "Pre-COVID Era"). During the COVID Era, both emergent and nonemergent neurosurgical services had resumed. A comparison of demographic and clinical factors between the 2 cohorts was performed. RESULTS: A total of 674 patients were included in the study (331 Pre-COVID and 343 COVID-Era patients). Overall, there was no change in the average monthly number of transfers (P = 0.66) or in the catchment area of referral hospitals. However, COVID-Era patients were more likely to be uninsured (1% vs. 4%), had longer transfer times (COVID vs. Pre-COVID Era: 18 vs. 9 hours; P < 0.001), required higher rates of surgical intervention (63% vs. 50%, P = 0.001), had higher rates of spine pathology (17% vs. 10%), and less frequently were admitted to the intensive care unit (34% vs. 52%, P < 0.001). Overall, COVID-Era patients did not experience delays to surgical intervention (3.1 days vs. 3.6 days, P = 0.2). When analyzing the subgroup of COVID-Era patients, COVID infection status did not impact the time of transfer or rates of operation, although COVID-infected patients experienced a longer time to surgery after admission (14 vs. 2.9 days, P < 0.001). CONCLUSION: The COVID-19 pandemic did not reduce the number of monthly transfers, operation rates, or catchment area for transfer patients. Transfer rates of uninsured patients increased during the COVID Era, potentially reflecting changes in access to community neurosurgery care. Shorter time to surgery seen in COVID-Era patients possibly reflects institutional policies that improved operating room efficiency to compensate for surgical backlogs. COVID status affeted time to surgery, reflecting the preoperative care that these patients require before intervention.

ABSTRACT

Presents a case report of a woman with depressive episodes, which began in early 2019 and was worsened by the change of her long-standing antidepressant regimen of fluoxetine to mirtazapine. Subsequently, she received 12 right unilateral ultrabrief pulse electroconvulsive therapy (ECT) treatments without any benefit. She experienced no benefit from 4 additional trials of antidepressants and during our evaluations over several weeks, her mood remained severely depressed. After 6 treatments, she experienced >50% reduction in her depression. However, her esketamine treatments were paused for 8 weeks due to COVID-19. Her depression worsened and a 4-week-long course of twice-weekly treatments was initiated, which resulted in a >50% reduction in her depression. After switching to weekly maintenance treatments, her symptoms of low mood, anhedonia, and suicidal ideation returned to her pre-treatment baseline. As she had responded well to twice-weekly treatments, the frequency of treatments was increased. In summary, this patient responded to twice-weekly esketamine treatments, experienced symptomatic worsening after switching to weekly treatments, but was able to attain remission with prolonged twice-weekly treatments.

ABSTRACT

Background: The whole of humanity has suffered dire consequences related to the novel coronavirus disease 2019 (COVID-19). Vaccination of the world base population is considered the most promising and challenging approach to achieving herd immunity. As healthcare organizations took on the extensive task of vaccinating the entire U.S. population, digital health companies expanded their automated health platforms in order to help ease the administrative burdens of mass inoculation. Although some software companies offer free applications to large organizations, there are prohibitive costs for small clinics such as the Good Health Associates Clinic (GHAC) for integrating and implementing new self-scheduling software into our e-Clinical Works (ECW) Electronic Health Record (EHR). These cost burdens resulted in a search that extended beyond existing technology, and in investing in new solutions to make it easier, more efficient, more cost-effective, and more scalable. Objective: In comparison to commercial entities, primary care clinics (PCCs) have the advantage of engaging the population for vaccination through personalized continuity of clinical care due to good rapport between their patients and the PCC team. In order to support the overall national campaign to prevent COVID-19 infections and restore public health, the GHAC wanted to make COVID-19 vaccination accessible to its patients and to the communities it serves. We aimed to achieve a coordinated COVID-19 vaccination drive in our community through our small primary care clinic by developing and using an easily implementable, cost-effective self-registration and scheduling web-based mobile platform, using the principle of "C.D.S. Five Rights". Results: Overall, the Moderna vaccination drive using our developed self-registration and scheduling web portal and SMS messaging mobile platform improved vaccination uptake (51%) compared to overall vaccination uptake in our town, county (36%), and state (39%) during April-July 2021. Conclusions: Based on our experience during this COVID-19 vaccination drive, we conclude that PCCs have significant leverage as "invaluable warriors", along with government and media education available, to engage patients for vaccination uptake; this leads to national preventive health spread in our population, and reduces expenses related to acute illness and hospitalization. In terms of cost-effectiveness, small PCCs are worthy of government-sponsored funding and incentives, including mandating EHR vendors to provide free (or minimal fee) software for patient self-registration and scheduling, in order to improve vaccination drive access. Hence, improved access to personalized informative continuity of clinical care in the PCC setting is a "critical link" in accelerating similar cost-effective campaigns in patient vaccine uptake.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) undergoes mutations at a high rate and with frequent genetic reassortment (antigenic drift/shift), leading to variability in targets. The receptor-binding domain (RBD) of the spike (S) protein has a major role in the binding of SARS-CoV-2 with human angiotensin-converting enzyme 2 (ACE2). Mutations at the RBD influence the binding interaction at the SARS-CoV-2 S-ACE2 interface and impact viral pathogenicity. Here, we discuss different reported mutations of concern in RBD, physicochemical characteristic changes resulting from mutated amino acids and their effect on binding between the RBD and ACE2. Along with mutation informatics, we highlight recently developed small-molecule inhibitors of RBD and the ACE2 interface. This information provides a rational basis for the design of inhibitors against the multivariant strains of SARS-CoV-2.

ABSTRACT

The ongoing pandemic of COVID-19 is a threat to various routine healthcare services. India's routine immunization (RI) campaign is one of largest ever known. In this review, we discuss the magnitude of disruption of RI activities due to COVID-19 pandemic, various causes of it and recommend ways to reduce the disruptions. Prominent literature databases were searched till April 30, 2021 for articles reporting disruptions of RI due to COVID-19. One study from India and numerous from outside India reported significant declines in the vaccine coverage rates during the lockdown period, which ranged from March 2020 till August 2020 in different regions of the world. Some reported disruptions for all vaccines, while a few reported sparing of birth doses. Shortage of healthcare workers due for them being diverted to patient care services and their reduced movement due to lockdowns and non-availability of public transport were prominent causes. Parents avoided RI sessions as they feared them or their children getting infected. They also faced travel restrictions, just like the healthcare workers. Children of school entry age and those from poorer socio-demographic profile appeared to miss the doses more frequently. Ministry of Health and Family Welfare, India has issued guidelines for conducting fixed and outreach RI sessions while following COVID-appropriate behavior. Promptly identifying missed out children and scheduling catch-up sessions is required to sustain the gains made over the decades by the immunization program of India.

ABSTRACT

BACKGROUND: The corona virus disease-2019 (COVID-19) infection is a current public health crisis, and it is challenging to the world health-care system. As there is no treatment, prevention is the crucial importance to break the chain of transmission of infection and prevent fatality among the high-risk populations. The aim of the study was to assess the Expressed COVID-19 preventive practices among health-care workers (HCWs) and the public visiting tertiary care hospital, AIIMS, Jodhpur. METHODOLOGY: A cross-sectional study was conducted among 406 HCWs and 238 public, recruited by convenient sampling technique. A validated and pretested self-structured practice questionnaire used to collect the data regarding COVID-19 preventive practice. The data were collected through online Google Forms and interview techniques and analyzed by software SPSS 26 version. RESULTS: Majority of 87.7% HCWs and 76.5% public always followed practice of hand wash with soap and water and sanitize for 20 s. Majority of 79.6% HCWs and 49.2% public maintain social distance in public place. Gender (χ 2 = 18.806 P ≤ 0.001) and education (χ 2 = 43.270 P ≤ 0.001) among HCWs and in public demographic variable income (χ 2 = 21.102 P = 0.002), religion (χ 2 = 13.302 P = 0.006) and source of information (χ 2 = 17.030 P = 0.026) was significantly associated with level of COVID-19 preventive practice. CONCLUSION: The study showed moderate level of COVID-19 preventive practice among HCWs and public. Based on this result, an effective IEC intervention programs can be designed to educate public and HCWs and follow a safe COVID-19 preventive practice.

ABSTRACT

COVID-19 has restricted singing in communal worship. We sought to understand variations in droplet transmission and the impact of wearing face masks. Using rapid laser planar imaging, we measured droplets while participants exhaled, said 'hello' or 'snake', sang a note or 'Happy Birthday', with and without surgical face masks. We measured mean velocity magnitude (MVM), time averaged droplet number (TADN) and maximum droplet number (MDN). Multilevel regression models were used. In 20 participants, sound intensity was 71 dB for speaking and 85 dB for singing (p < 0.001). MVM was similar for all tasks with no clear hierarchy between vocal tasks or people and > 85% reduction wearing face masks. Droplet transmission varied widely, particularly for singing. Masks decreased TADN by 99% (p < 0.001) and MDN by 98% (p < 0.001) for singing and 86-97% for other tasks. Masks reduced variance by up to 48%. When wearing a mask, neither singing task transmitted more droplets than exhaling. In conclusion, wide variation exists for droplet production. This significantly reduced when wearing face masks. Singing during religious worship wearing a face mask appears as safe as exhaling or talking. This has implications for UK public health guidance during the COVID-19 pandemic.

ABSTRACT

PURPOSE: Synthesis of available evidence on clinical practice in gynaecological oncology during the COVID-19 pandemic is highly warranted, as women with cancer are at increased risk due to their systemic immunosuppressed state and changes in their care are inevitable. Rapid review of available data is a quick way of providing useful information and insight into the way medical practice has been affected by the COVID pandemic. METHODS: We conducted a systematic rapid review, based on a literature search of MEDLINE/PubMed, Embase, and Cochrane CENTRAL. We considered all studies on gynaecological oncology care during the COVID-19 pandemic using relevant keywords and MeSH terms. Selection criteria were English language, studies with more than five cases and publication in peer-review journal. RESULTS: Nine retrospective studies, one systematic review and five questionnaire surveys were included. Quality of the studies has been assessed. Development of higher quality evidence is warranted. Mortality of COVID-19 infection is higher in patients with gynaecological cancer than in non-cancer patients. Reported delays in diagnosis and management of cancer and changes in treatments, may affect the natural history of cancer and increase patients' anxiety and fear of disease progression while causing concerns to healthcare professionals affecting their clinical practice. The number of new diagnoses has declined. Prioritization is important, face-to-face interactions should be limited, and appropriate protective measures are essential. Cancer surgery, chemotherapy, and radiotherapy should continue as high priority practices. CONCLUSION: The COVID-19 pandemic has affected clinical practice significantly. Adaptations in clinical practice may improve mortality and complication rates.

ABSTRACT

Aerosols and droplets generated from expiratory events play a critical role in the transmission of infectious respiratory viruses. Increasingly robust evidence has suggested the crucial role of fine aerosols in airborne transmission of respiratory diseases, which is now widely regarded as an important transmission path of COVID-19. In this report, we used CFD modelling to investigate the efficiency of using portable air purifiers containing HEPA filters to reduce airborne aerosols in hospitals and serve as a potential retrofit mitigation strategy. We used a consulting room to set up our simulations because currently the clearance time between consultations is the controlling factor that limits the patient turnover rate. The results suggest the inlet/suction of the air purifier unit should be lifted above the floor to achieve better clearance efficiency, with up to 40% improvement possible. If multiple air purifiers are used, the combined efficiency can increase to 62%. This work provides practical guidance on a mitigation strategy that can be easily implemented in an expedient, cost-effective and rapid manner, and paves the way for developing more science-informed strategies to mitigate the airborne transmission of respiratory infections in hospitals.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has disrupted social and economic life globally. The global pandemic COVID-19 caused by this novel SARS-CoV-2 shows variable clinical manifestations, complicated further by cytokine storm, co-infections, and coagulopathy, leading to severe cases and death. Thrombotic complications arise due to complex and unique interplay between coronaviruses and host cells, inflammatory response, and the coagulation system. Heparin and derivatives are World Health Organization (WHO) recommended anticoagulants for moderate and severe Corona Virus Disease 19 (COVID-19), that can also inhibit viral adhesion to the cell membrane by interfering with heparan sulfate-dependent binding to angiotensin-converting enzyme 2 (ACE2) receptor. Heparin also possesses anti-inflammatory, immunomodulatory, antiviral, and anti-complement activity, which offers a benefit in limiting viral and microbial infectivity and anticoagulation from the immune-thrombosis system. Here we present a case study of the pathophysiology of unexpected COVID-19 coagulopathy of an obese African American patient. While being on therapeutic warfarin since admission, he had a dismal outcome due to cardio-pulmonary arrest after the sudden rise in D-dimer value from 1.1 to >20. This indicates that for such patients on chronic warfarin anticoagulation with "moderate COVID 19 syndromes", warfarin anticoagulation may not be suitable compared to heparin and its derivatives. Further research should be done to understand the beneficial role of heparin and its derivatives compared to warfarin for COVID-19 inflicted patients.

ABSTRACT

BACKGROUND: The 2020 Coronavirus pandemic continuing spread of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). At the moment, there is no specific antiviral treatment or monoclonal antibodies or vaccines available for COVID-19. SARS-CoV-2 is positive-stranded RNA viruses with a crown-like appearance due to the occurrence of spike (surface) glycoproteins on the envelope. In the present study, the computational method used to predict the significant linear B cell epitopes of SARS-CoV-2 surface glycoprotein. METHODS: FASTA sequence of SARS-CoV-2 surface glycoprotein was retrieved from the NCBI database, and further its primary and secondary structure was analyzed for its physical and chemicals properties. IEDB server was used to predict the B-cell epitopes. RESULTS: ABCprep server and IEDB server prediction results for B-cell epitopes showed 16 and 21 linear epitope sequences respectively in the surface glycoprotein of SARS-CoV-2. CONCLUSIONS: Obtained results conclude that predicted B-cell Epitopes may serve as an immunogen for eliciting monoclonal antibodies which can be used as a potential candidate for the treatment or diagnostic purpose for COVID-19.

ABSTRACT

Recently, we have witnessed an unprecedented increase in the number of patients suffering from respiratory tract illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 virus is a single-stranded positive-sense RNA virus with a genome size of ~29.9 kb. It is believed that the viral spike (S) protein attaches to angiotensin converting enzyme 2 cell surface receptors and, eventually, the virus gains access into the host cell with the help of intracellular/extracellular proteases or by the endosomal pathway. Once, the virus enters the host cell, it can either be degraded via autophagy or evade autophagic degradation and replicate using the virus encoded RNA dependent RNA polymerase. The virus is highly contagious and can impair the respiratory system of the host causing dyspnea, cough, fever, and tightness in the chest. This disease is also characterized by an abrupt upsurge in the levels of proinflammatory/inflammatory cytokines and chemotactic factors in a process known as cytokine storm. Certain reports have suggested that COVID-19 infection can aggravate cardiovascular complications, in fact, the individuals with underlying co-morbidities are more prone to the disease. In this review, we shall discuss the pathogenesis, clinical manifestations, potential drug candidates, the interaction between virus and autophagy, and the role of coronavirus in exaggerating cardiovascular complications.
