Computational Structural and Functional Analyses of ORF10 in Novel Coronavirus SARS-CoV-2 Variants to Understand Evolutionary Dynamics.

Introduction: In an effort to combat SARS-CoV-2 through multi-subunit vaccine design, during studies using whole genome and immunome, ORF10, located at the 3' end of the genome, displayed unique features. It showed no homology to any known protein in other organisms, including SARS-CoV. It was observed that its nucleotide sequence is 100% identical in the SARS-CoV-2 genomes sourced worldwide, even in the recent-most VoCs and VoIs of B.1.1.529 (Omicron), B.1.617 (Delta), B.1.1.7 (Alpha), B.1.351 (Beta), and P.1 (Gamma) lineages, implicating its constant nature throughout the evolution of deadly variants. Aim: The structure and function of SARS-CoV-2 ORF10 and the role it may play in the viral evolution is yet to be understood clearly. The aim of this study is to predict its structure, function, and understand evolutionary dynamics on the basis of mutations and likely heightened immune responses in the immunopathogenesis of this deadly virus. Methods: Sequence analysis, ab-initio structure modeling and an understanding of the impact of likely substitutions in key regions of protein was carried out. Analyses of viral T cell epitopes and primary anchor residue mutations was done to understand the role it may play in the evolution as a molecule with likely enhanced immune response and consequent immunopathogenesis. Results: Few amino acid substitution mutations are observed, most probably due to the ribosomal frameshifting, and these mutations may not be detrimental to its functioning. As ORF10 is observed to be an expressed protein, ab-initio structure modeling shows that it comprises mainly an α-helical region and maybe an ER-targeted membrane mini-protein. Analyzing the whole proteome, it is observed that ORF10 presents amongst the highest number of likely promiscuous and immunogenic CTL epitopes, specifically 11 out of 30 promiscuous ones and 9 out of these 11, immunogenic CTL epitopes. Reactive T cells to these epitopes have been uncovered in independent studies. Majority of these epitopes are located on the α-helix region of its structure, and the substitution mutations of primary anchor residues in these epitopes do not affect immunogenicity. Its conserved nucleotide sequence throughout the evolution and diversification of virus into several variants is a puzzle yet to be solved. Conclusions: On the basis of its sequence, structure, and epitope mapping, it is concluded that it may function like those mini-proteins used to boost immune responses in medical applications. Due to the complete nucleotide sequence conservation even a few years after SARS-CoV-2 genome was first sequenced, it poses a unique puzzle to be solved, in view of the evolutionary dynamics of variants emerging in the populations worldwide.

Effect of Nation-wide Lockdown on Palliative Care Services in a Tertiary Care Centre in India: A Retrospective Observational Study.

BACKGROUND: The ongoing coronavirus disease 2019 (COVID-19) pandemic has affected all the aspects of life of mankind, posing unique challenges for health-care services. In order to contain the spread of the virus, a countrywide mass lockdown has been imposed in India. Although the lockdown has modified the epidemic trajectory, it has affected the lives of many non-COVID patients. Patients in need of care could not approach hospitals. METHODS: This retrospective observational study was conducted in the Department of Onco-Anaesthesia and Palliative Medicine at a tertiary care center in India. The yearly data of patient flow for the year 2019 was compared with that during the lockdown. RESULTS: The single-day average of out-patients, in-patients, and other department consultation requests requiring palliative care decreased drastically during the lockdown in comparison to the previous year. The single-day average of teleconsultations increased more than double during the lockdown. CONCLUSION: Although lockdown decreases the spread of the epidemic, it increases the suffering of other patients who require medical care. Various steps have to be adopted in the regular working pattern of hospitals to cater to the needs of the patients requiring care, without increasing the risk of contracting COVID-19.

Concerns of Health Care Professionals Managing non-COVID Patients during The COVID-19 Pandemic: A Descriptive Cross- Sectional Study.

CONTEXT: The coronavirus pandemic has put an unprecedented burden on the health-care workers who are the cornerstone of the work system, preparing to mitigate its effects. Due to the lack of protective equipments, guidelines for managing patients, or proper training and education regarding the same, health care professionals (HCPs) working in non-COVID areas may face even greater problems than those working in COVID areas of a hospital. Our aim was to find out the concerns of HCPs working in non-COVID areas. SUBJECTS AND METHODS: After obtaining institutional ethics approval, a descriptive cross-sectional study was planned. An online Google-based questionnaire was rolled out to all doctors through various social media platforms who were dealing with COVID-negative patients. RESULTS: We received a total of 110 responses. 84.5% of participants were concerned about the risk of infection to self and family, 67.3% were concerned by the disruption of their daily activities. 56.4% of HCPs were disturbed by the lack of any concrete protocol for patient management. Less staff availability, delay in discharging duties toward their patients, and increased workload were other concerns. More than half of the doctors received N-95 masks whenever required and were trained in donning and doffing of Personal protective equipment. Sixty-eight percemt of our respondents labeled their current quality of life as stressful. CONCLUSION: It is the need of the hour to develop a comprehensive strategy focussing on the above challenges that HCPs working in non-COVID areas are facing. This will go a long way in not only providing holistic care to the patients but also in controlling this pandemic.

Smartphone-Based Telemedicine Service at Palliative Care Unit during Nationwide Lockdown: Our Initial Experience at a Tertiary Care Cancer Hospital.

BACKGROUND AND AIMS: With the COVID-19 pandemic, lockdown, and fear from contagion, the advantages of telemedicine are clearly outweighing the setbacks by minimizing the need for individuals to visit health-care facilities. Our study aims to assess how palliative medicine physicians could follow up on cancer patients and barriers they faced, discuss their results, and evaluate their treatment response with the help of telemedicine. MATERIALS AND METHODS: We conducted a prospective analysis of the smartphone-based telemedicine service at our palliative care (PC) unit from March 25, 2020, to May 13, 2020. We recorded the patient's reason for call, main barriers to a hospital visit, and the assistance given to them by the physician on call. Each caller was asked to measure his/her satisfaction with the service on a 4-point scale. RESULTS: Out of 314 patients, 143 (45.54%) belonged to Delhi and 171 (54.46%) belonged to other states. 157 patients sought help for symptom management; 86 patients needed to restock their opioid medications. Seventy-one patients required information regarding their oncological treatments requiring consultation from other departments. Titration of oral opioids and medication prescription (n = 129), contact details of other PC units at their native state for opioid procurement (n = 55), and attachment to our community-based PC service (n = 22) were main modes of management. Fifty-six patients were very satisfied and 152 patients were satisfied with the service. CONCLUSION: Telemedicine is the future of health-care delivery systems. In PC, we deal with immunocompromised debilitated cancer patients and telemedicine is immensely helpful for us to provide holistic integrated care to these patients who are unable to visit hospitals regularly.

Opioid Dispensing Patterns from a Tertiary Care Cancer Hospital during the Nationwide Lockdown in COVID-19 Pandemic.

INTRODUCTION: During the current COVID-19 crisis, striking a balance between adequate pain relief in advanced malignancy patients and avoiding hospitals due to fear of contracting the infection has been the biggest challenge for patients as well as palliative care physicians. This study explored the trends in opioid dispensing for cancer pain before and during the lockdown. METHODS: The trends were calculated based on an analysis of quantity of all opioids dispensed. March 24, 2020, was considered as a cutoff for analyzing before and during lockdown period dispensing trends. No information regarding individual patients was retrieved in the current study. RESULTS: There was a decrease in total morphine, tramadol, and fentanyl patch dispensing parallel to decrease in total number of patients visiting the outpatient department. However, there was a statistically significant increase in per capita opioid dispensing during the lockdown period. There was also an increase in the proportion of cancer pain patients that were dispensed morphine during the lockdown. CONCLUSION: Despite the lockdown, the palliative care team at Institute Rotary Cancer Hospital has continued to provide adequate pain relief to patients that could manage to reach the center. Policy-makers need to be cognizant of the pain relief needs of cancer patients in times when accessing hospitals is becoming increasingly difficult. Cancer-related pain and mortality could well be the next pandemic once the current COVID-19 begins to reduce.

Impact of COVID-19 Pandemic on Cancer Surgical Services-AIIMS, New Delhi Experience.

COVID pandemic has impacted cancer care delivery and cancer surgical services globally. There is an urgent need to study the extent of the impact of COVID on cancer surgery and individual institutional response and strategies adopted to counter the adverse impact. A review of administrative and clinical policy changes adopted at the tertiary cancer center to combat COVID pandemic and resume cancer surgical services were performed. A retrospective comparative analysis of cancer out-patient census during COVID pandemic affected year and the preceding normal year along with cancer surgery data audit for the same periods was performed to assess the impact of the pandemic on cancer surgery. In addition, COVID infection rates among cancer surgery patients and healthcare workers were evaluated. There was approximately a 50% reduction in cancer outpatient registrations during COVID pandemic affected year. A trend of increasing footfalls was noted with decreasing COVID intensity and opening of lockdowns. There was a 33% reduction in major elective surgery and a 41% reduction in emergency surgery performed during the COVID period. As far as cancer surgeries are concerned, there was a 12-50% reduction in volumes involving different subsites. Overall COVID positivity rates among cancer surgery patients was low (8.17%), and approximately 30% of healthcare workers involved in cancer surgery were tested positive for COVID during the study period. Results of the current study indicate a significant impact of COVID pandemic on cancer surgical services. There was a significant impact on outpatient visits and cancer surgery volumes. However, a multidisciplinary-coordinated team approach, effective administrative and policy implementation, adoption of revised surgical safety and anesthesia protocols, COVID screening, and testing protocols facilitated resumption of cancer surgical services without adverse impact on surgical outcomes.

Telemedicine as an Acceptable Model of Care in Advanced stage Cancer Patients in the Era of Coronavirus Disease 2019 - An Observational Study in a Tertiary Care Centre.

OBJECTIVES: The availability of routine care for patients with cancer during the coronavirus disease 2019 (COVID-19) pandemic has become challenging, and the use of telemedicine can be promising in this area. The objective of the study is to evaluate the feasibility of telemedicine-based palliative interventions in cancer patients. MATERIALS AND METHODS: This retrospective study was conducted in a tertiary care centre with 547 follow-up patients who used palliative medicine teleconsultation services. The following data were retrieved from the records: Patient's reason for the call, the main barriers to a hospital visit, the assistance given to them by the physician on the call and the patients' satisfaction with the service on a 4-point scale. The data were analysed using percentages for categorical variables and mean/standard deviation for quantitative variables. RESULTS: Out of the 547 patients, 462 (84.46%) utilised voice calling service, and the major reason for not visiting the hospital were cited to be fear of contracting COVID-19 (37.3%), inability to attend due to health constraints (7.13%) and issues with transportation (48.8%). The majority of the calls (63.62%) calls were regarding uncontrolled symptoms of the primary diseases. A total of 402 (73.49%) patients were very satisfied, and a total of 399 (72.94%) decided to continue to use this medium in the future as well. CONCLUSION: Telemedicine is a good modality for the assessment of chronic pain and providing symptomatic supportive care in patients with cancer in the COIVD-19 pandemic.

The COVID-19 pandemic: a new epoch and fresh challenges for cancer patients and caregivers-a descriptive cross-sectional study.

PURPOSE: Cancer patients and their caregivers are overwhelmed with features of uncertainty, fear, shock, worry, anxiety, sadness, and grief. To add on to their misery, the COVID-19 pandemic has severely afflicted the cancer care delivery. The study was conducted to observe the challenges faced by cancer patients and their caregivers and to formulate strategies for oncological setups to overcome those challenges. METHODS: After obtaining institutional ethical clearance, a descriptive cross-sectional study was conducted to observe the challenges faced by patients and their caregivers at the level of various domains (physical, logistic, psychological, socioeconomic, and spiritual) who visited the outpatient and inpatient department of cancer pain and palliative care unit. The results were expressed in absolute numbers. RESULTS: Major challenges encountered were suffering from physical symptoms like pain, nausea, vomiting, dyspnea (90%), postponement of cancer treatment (80%), fear of contracting COVID infection due to hospital visit (93.5%), lack of accommodation (70%), and lack of spiritual clarity and hope (50%). CONCLUSIONS: Major challenges faced by patients were in physical and psychological domains, and those by caregivers were in socioeconomic domains and handling physical symptoms of their patients. It is imperative to recognize and be cognizant of the challenges faced by cancer patients and their caregivers. Health care setups should formulate strategies to alleviate these challenges and provide holistic care to cancer patients. These strategies will hold in good stead for future pandemics also.

OBJECTIVES: Novel coronavirus (COVID-19) pandemic has brought to the fore various challenges faced by pain and palliative care physicians working in oncology setup all over the country. Cancer care has been afflicted a lot during the pandemic, with challenges faced by patients and their caregivers as well as the healthcare workers. The questionnaire based online survey was conducted to explore the personal challenges faced, strategies adopted and to compare the challenges between different oncology setups. MATERIALS AND METHODS: After obtaining institutional ethical clearance the online questionnaire prepared through Google forms was rolled out to pain and palliative care physicians working all over the country with the help of social media platforms. The results were expressed in absolute number, percentage and comparisons were made with the help of Fisher's exact test. RESULTS: Maximum challenges faced were the fear of carrying infection back home (91%), the possibility of attending to a COVID positive case in day to day clinical practice because of inadequate space and screening (62%) and limited services provided by NGO's during pandemic (71%). Strategies commonly adopted were the provision of necessary personal protective equipment (83%), the conduct of educational sessions for the task force members (67%), maximum utilization of available space in the hospital (85%) and stockpiling of necessary medications and equipment (75%). CONCLUSION: It is the need of the hour to formulate strong and effective strategies to overcome the challenges encountered by pain and palliative care physicians so that we are equipped in the future to deal with any kind of pandemics.

The incidence of anosmia in patients with laboratory-confirmed COVID 19 infection in India: An observational study.

BACKGROUND AND AIMS: Acute loss of smell or anosmia is a common and sometimes the only symptom observed in patients with coronavirus disease-2019 (COVID-19). The objective of the study was to determine the prevalence, time of onset, and duration of anosmia in patients with COVID-19 infection and the association of anosmia with other symptoms and eosinophil count. MATERIAL AND METHODS: Two hundred patients with laboratory-confirmed COVID-19 infection, who were asymptomatic or mildly symptomatic were assessed for olfaction with a nonirritant odor. The presence of anosmia was recorded, and a questionnaire integrating the anosmia reporting tool was filled. Patients with anosmia/hyposmia were followed telephonically at 7 and 14 days for resolution of anosmia and other symptoms. The presence of anosmia was correlated with eosinophil count. RESULTS: Of the 200 COVID-19 patients, 87% were symptomatic. More than half of the patients had fever (56%). Anosmia was observed in 30% of the patients and hyposmia in 4% of patients. In 41% of the patients, olfactory loss was reported before diagnosis. The mean duration of anosmia was 7.8 (± 5) days; 97% of patients recovered with a resolution of symptoms within 2 weeks. Ageusia was the most commonly and significantly associated symptom with anosmia (66%, n = 45) followed by sore throat (41%), and rhinorrhea (28%). The symptoms in both the sexes were comparable. Absolute eosinophil count of <40/µL was observed in 59 patients (29.5%) and an absolute eosinophil count of 0 in 17 patients (8.5%). Among the 68 anosmic patients, 36 (47%) patients had eosinopenia, which was statistically significant. CONCLUSION: Anosmia is an early and sometimes the only symptom in approximately one-third of the patients with COVID-19 infection. Eosinophil count should be checked in anosomic patient with suspicion of COVID-19 infection. Objective tools for olfactory and gustatory assessment should be brought into practice for early and prompt diagnosis to control the spread of the disease.

Palliative Care Delivery in Cancer Patients in the Era of Covid-19 Outbreak: Unique Needs, Barriers, and Tools for Solutions.

World is facing a pandemic recently due to the outbreak of COVID-19 infection. Cancer has been identified as one of the major comorbidities which cause more severe disease due to COVID-19 infection. Moreover, there are several resource limitations and restrictions to avail the standard oncological health facilities due to robust measures taken for infection control. In this situation, palliative care in cancer patients deserves special attention. Their symptom management, psychological, social, cultural needs tremendously increase during the epidemic. Thus, we need to recognize the unique palliative care needs of cancer patients during pandemic and formulate the plan to maintain continuity of services. Triaging systems are essential tools for proper resource allocation during a pandemic. Therefore, we suggest triaging tools for emergency in hospital palliative care services: community-based palliative care and end of life care for cancer patients. Incorporation of newer technologies and identifying the potential resources are the other key components of the preparedness strategy.

Rendezvous of Cancer Patients with Logistic and Socioeconomic Challenges during COVID-19 Pandemic: A Case Series.

The coronavirus disease 2019 pandemic has shaken the health-care infrastructure worldwide and has led to enormous challenges for cancer patients. They are suffering on various fronts during this pandemic, especially the often overlooked ones such as logistic and socioeconomic. Through the case series, we have highlighted the various components of these challenges the cancer patients are facing and tried to emphasize that the health-care setups and government along with nongovernmental organizations have to come on the forefront to help the patients mitigate these challenges.

Unraveling the Role of Palliative Surgery in the Era of COVID-19 Pandemic.

Palliative surgery forms an important pillar of palliative treatment to provide holistic care to cancer patients in the form of providing relief from pain, local control of disease, hemorrhage, and for the purpose of rehabilitation. During the COVID-19 pandemic, we report the successful management of two cases of colorectal cancer which came under the category of high priority and underwent palliative surgery to provide relief from pain.

Multiple Caregiving Role with the Novel Challenge of COVID-19 Pandemic: A Crisis Situation.

Caregivers of cancer patients in the COVID-19 pandemics have been faced with new complexities and challenges related to their patient's care. It has added tremendous stress to the previous multiple caregiving roles. We present the journey of a caregiver of cancer survivor who had played multiple care giving roles for the past 10 years. With the added challenge of the pandemic the caregiver faced severe psychological distress concerning his caregiving role. This was addressed to a large extend with counseling and empathy. Communication is an important measure to relieve the distress and address the complexities faced by caregivers.
