Fruits as Boosters of the Immune System

Immunity is the major mechanism of host defence system against infectious and chronic diseases. The recent global concern of recent viral infection of SARS-CoV-19 has raised the demand of functional foods, nutraceuticals and fruits that can boost immunity. This will help in managing the overall physiological health and prevention of infectious and chronic diseases. Medicinal plants and fruits can help in boosting immunity through modulation of immune system and changing the types of immune response such as involvement of the induction, expression or amplification of the genes and proteins in inflammation and antioxidant system. The traditional medicine systems have used a wide variety of plants and fruits as supplement for immunomodulation including those for stimulation of immune system as well as immune compromisation deemed per se. Some of the plants that have been listed for immune boosting abilities included Curcuma longa, Withania somnifera, Phyllanthus emblica, Azadirachta indica, Panax ginseng, Rhododendron spiciferum, Caesalpinia bonducella, Tinospora cordifolia, Capparis zeylanica, Asparagus racemosus, Nelumbo nucifera, Arnica montana, Calendula officinalis, Echinacea purpurea and Euphorbia tirucalli. Reports indicate that a wide variety of phytochemicals like polysaccharide, alkaloids, flavonoids, terpenoids, lactones and glycoside have shown immunomodulatory properties under different pathophysiological conditions. Amongst the diverse chemical profile of plant extracts, polysaccharides are the water-soluble molecules that could activate immune responses when interacting directly with immune cells, while hydrophobic compounds like flavonoids such as quercetin and luteolin and terpenoids such as sesquiterpene lactones and curcumin showed potent immunomodulatory effects. Growing evidences suggest that phytochemicals from functional foods and fruits may be useful in maintaining the cytokine and chemokine balance, regulating oxidative status of cells, and targeting the specific cellular receptors as therapeutic targets. This chapter comprehensively enlists the plant resources with immune boosting abilities and explore their phytochemical characterization and molecular mechanism behind their protective effects. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.

Role of telemedicine in anesthesia: Are we ready yet?

Telemedicine is a modality which utilizes technology to provide and support health care across large distances. It has redefined the practices of medicine in many specialties and continues to be a boon for clinicians on many frontiers. Its role in the branch of anesthesia remains largely unexplored but has shown to be beneficial in all the three phases: pre-operative, intra-operative, and post-operative. Now time has come that anesthesiologists across the globe reassess their strategies and utilize the telemedicine facilities in the field of anesthesia.Copyright © 2021 EDP Sciences.

Covid19 Disease Assessment Using CNN Architecture

Recently, the COVID-19 pandemic has emerged as one of the world's most critical public health concerns. One of the biggest problems in the present COVID-19 outbreak is the difficulty of accurately separating COVID-19 cases from non-COVID-19 cases at an affordable price and in the initial stages. Besides the use of antigen Rapid Test Kit (RTK) and Reverse Transcription Polymerase Chain Reaction (RT-PCR), chest x-rays (CXR) can also be used to identify COVID-19 patients. Unfortunately, manual checks may produce inaccurate results, delay treatment or even be fatal. Because of differences in perception and experience, the manual method can be chaotic and imprecise. Technology has progressed to the point where we can solve this problem by training a Deep Learning (DL) model to distinguish the normal and COVID-19 X-rays. In this work, we choose the Convolutional Neural Network (CNN) as our DL model and train it using Kaggle datasets that include both COVID-19 and normal CXR data. The developed CNN model is then deployed on the website after going through a training and validation process. The website layout is straightforward to navigate. A CXR can be uploaded and a prediction made with minimal effort from the patient. The website assists in determining whether they have been exposed to COVID-19 or not. © 2023 IEEE.

Potential Influence of Parasitic Interactions on COVID-19 Pathology and Epidemiology

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) has affected the human lives worldwide. The emerged disease and pandemic have challenged the public health particularly in the countries with middle or low economic condition including India. The transmigration of this zoonotic virus from bats and pangolins to humans in a process of genetic drift has targeted the lungs and respiratory and cardiovascular damages. Analyzing the infection of SARS-CoV-2 and COVID-19 as a parasitic component in the human physiology, it drew considerable attention to analyze the impact of other residential parasitic entities. This adds to the involvement of the infection and proliferation of other human parasites especially malaria, soil-transmitted helminths (STH), and schistosomes. The coevolution mechanisms pertain to manage the growth and proliferation of pathogenic and nonpathogenic parasites in a cellular micromilieu. One of the key factors that have appeared is COVID-19-induced cytokine storm in cells which is characterized as a physiological state of cells with a hyperinflammatory response. In case of SARS-CoV-2 infection, this phenomenon has been even critically implicated especially with an exacerbated response of IL-6. Herein, this perspective analysis explores the potential influence of parasite coinfection in COVID-19 infection especially the interaction of parasites of malaria, STH, and schistosomes. In a nutshell, the correlation analysis between COVID-19 and other human parasites and diseases presented globally has shown a negative correlation with the COVID-19 cases. Thus, extensive large-scale epidemiological studies would be required to further establish the correlation between parasitic interactions with COVID-19 and to resolve the ambiguity existing in variable repertoire. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2021.

Design of COVID19 Detection based on Relative Eccentric Feature Selection using Deep Vectorized Regressive Neural Network for Corona Virus

The world has seen various diseases in different variants, numerous pandemics in the twentieth century like COVID-19. Fly infections are the fundamental driver of contaminations. COVID-19 declared a global pandemic with major impacts on economies and societies around the world. The diagnosis of COVID19 or non-COVID-19 cases early detection at the correct separation early stages of disease are one of the main concerns of the current coronavirus pandemic. At present, accurate detection of coronavirus disease usually takes a long time and is prone to human error. To address this problem, the proposed Deep learning and Design of COVID19 detection based on Relative Eccentric Feature Selection (REFS) Using Deep Vectorized Regressive Neural Network (DVRNN) for corona virus the early detection of the COVID19 virus. Initially collects the COVID19 sample test dataset, then the raw dataset trained into preliminary process is used to remove unwanted noise. After that preliminary processed dataset trained into the feature selection process is done to identify the best features of COVID19 using Ensemble recursive selection. Further, the proposed DVRNN algorithm is done to classify the accurate detection of coronavirus. The proposed model would be useful for the Timely and accurate identification of various stages of coronavirus. Therefore, it can detect the accurate results of COVID19 effectively and accomplish good performance compared with previous methods. © 2023 IEEE.

Presentation of Takotsubo Cardiomyopathy in a Patient with Coronavirus-19 Disease

Case Report: It is well documented that Coronavirus Disease 19 (COVID-19) patients who suffer cardiac injury have a higher mortality rate, however the exact mechanism of cardiac injury and potential complications are still unknown. Takotsubo Cardiomyopathy (TCM), which was first described in 1990 in Japan, is characterized by a transient systolic and diastolic left ventricular dysfunction with a range of wall motion abnormalities predominantly affecting women often following an emotional or physical trigger. Though TCM is seen less commonly as a cardiac complication of COVID-19, with increasing rates of cardiovascular events due to COVID-19, TCM should be taken into consideration as a potential diagnosis for a COVID-19 positive patient. Case Description: The case of a 75-year old female with a history significant for hypertension, type 2 diabetes mellitus, hyperlipidemia, and gastroesophageal reflux disease presented to the Emergency Department after a ground level fall and subsequent left hip pain. Upon primary survey, EKG showed persistent sinus tachycardia in the 130-150s, with intermittent borderline dynamic changes and a troponin that was mildly elevated at 0.10, and an initial false negative COVID-19 test. Preoperative echocardiogram showed normal left ventricle size, no regional wall abnormalities, and a left ventricular ejection fraction (LVEF) of 60-65%. In post-operative care, EKG illustrated dynamic changes in the form of ST elevation in the lateral precordial leads, as well as an increase in the cardiac troponins, from 0.07 to 3.51. A subsequent echocardiogram illustrated a drop in her ejection fraction from 60-65% to 30-35%, with evidence of left ventricular systolic dysfunction that was not noted on previous echocardiograms. Following the Mayo clinic diagnostic criteria, this patient met the diagnostic criteria for TCM, as evident by new electrocardiograph findings, non-obstructive cardiac catherization findings, echocardiogram findings illustrating transient left ventricular systolic dysfunction, modest elevations in cardiac troponins as well as the patient being a post-menopausal female. Subsequent echocardiogram on 2 week follow up showed a rebound in her ejection fraction to 50-55%. Discussion(s): Possible outcomes of TCM include cardiogenic shock, respiratory failure, and death. It is imperative that clinicians consider TCM as a possible diagnosis when treating COVID-19 patients that may be exhibiting cardiac complications. Frequent ECG monitoring and a vigilant differential should include TCM in patients presenting with COVID-19.

From Covid to Bovid to Ovid: A Case of Disseminated Cryptococcus Neoformans

Case Report: Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus, with C. neoformans and C. gattii being the most common species to cause human disease. Immunocompromised individuals are predisposed to infections with C. neoformans, which has known predilection to CNS and pulmonary lymph nodes. We present a unique case of disseminated cryptococcosis in the setting of end-stage renal disease (ESRD), cirrhosis, tumor necrosis factor inhibitor use and steroid use for COVID19. Method(s): A single-patient case report was conducted after IRB approval. Case Presentation: A 55-year-old woman with uncontrolled diabetes, lupus, rheumatoid arthritis on adalimumab, hepatitis C status post boceprevir, cirrhosis, former IV drug use, and ESRD on hemodialysis via bovine arterial-venous fistula graft presented with worsening dyspnea, cough, and altered mental status. Three months prior, patient was admitted to an outside hospital for COVID19, complicated by pulmonary embolism status post anticoagulation therapy. Patient was treated with an unknown steroid regimen, which was continued by a second outside facility when symptoms failed to improve. Patient then presented to our facility 24 hours after discharge due to continued symptoms. On admission, patient was noted to have altered mentation and hypoxia with pulmonary edema on chest x-ray and was urgently hemodialyzed. Further work-up was obtained due to non-resolving symptoms, including blood and sputum cultures, cocci serology and QuantiFERON gold. CT chest revealed bilateral consolidations. Patient was started on antibiotics for presumed hospital-acquired pneumonia. During the hospital stay, preliminarily blood cultures grew yeast and patient was started on Micafungin. However, Micafungin was changed to Liposomal Amphotericin B as ovoid structures seen on gram stain could not confirm nor rule out cryptococcus. Subsequent bronchial wash and bronchoalveolar lavage cultures, as well as final blood cultures resulted Cryptococcus neoformans. Serum cryptococcus antigen returned reactive, titer 1:512. Antibiotics were discontinued and Isavuconazonium was started with Liposomal Amphotericin B. Due to recurrent headaches, lumbar puncture was obtained and revealed lymphocytic pleocytosis without cryptococcal antigenicity. Patient completed 14 days of Liposomal Amphotericin B and Isavuconazole with continuation of Isavuconazole upon discharge. Conclusion(s): Disseminated cryptococcosis in non-HIV patients is rare in the modern HIV era. Clinicians should be aware and include it in their differential of any patient with multiple risk factors for opportunistic infection. In patients with cirrhosis and ESRD, treatment is limited given altered pharmacokinetics. Studies have shown improved survival with the addition of Isavuconazole in patients with disseminated cryptococcosis with CNS involvement in the setting of chronic liver disease and ESRD.

Severe Acute Hemolytic Anemia Post Covid Vaccination

Case Report: A 26-year-old woman with a history of warm autoimmune hemolytic anemia, immune thrombocytopenia, triple positive antiphospholipid syndrome, and chronic migraine presented to the emergency department with worsening generalized fatigue for one week associated with headache, dyspnea on exertion, nausea, vomiting and lightheadedness. Of note, she had received her second dose of mRNA COVID-19 vaccine 4 days prior to presentation. On admission, patient was found to be severely anemic with a hemoglobin of 4.3g/dL which is decreased from her baseline hemoglobin of 9-10.5g/dL;however, W-AIHA precluded the administration of blood product until adequate blood with the appropriate antibodies could be acquired. During the hospitalization, hemoglobin decreased to 3.3g/dL. Patient was then administered the most compatible blood product which she tolerated well. Hematology was consulted who started the patient on hydroxychloroquine, high dose methylprednisolone, and Intravenous Immunoglobulin (IVIG). Throughout the admission, the patient remained asymptomatic. After 2 days of IVIG, three days of high dose glucocorticoids, and one unit of packed red blood cells, the patient's hemoglobin increased to 7.2g/dL. Patient was discharged home on prednisone taper and hydroxychloroquine. Conclusion(s): Episodes of hemolytic anemia after either the first or second dose of mRNA COVID vaccines are rare and have occurred in patients with known hematological pathology as well as patients without any history of hematologic or immunologic disorders. When taking the history of patients presenting with hemolytic anemia, it is important to query recent vaccinations as, while rare, mRNA COVID vaccine may well be the etiology. While this ultimately will likely not change patient management, this information would be beneficial for further study.

Marching Ahead through the Pandemic: Continuing Anesthesia Services in COVID Era-Our Experience from a Tertiary Care Cancer Centre

Introduction This paper aims to provide an overview of the administrative and clinical preparations done in a tertiary care cancer hospital in continuing operation theatre (OT) services through the COVID pandemic.Methods Retrospective data collection, data for the past 1.5 years (COVID period) March 2020 to August 2021 were compared to surgical output for a similar duration of time before the COVID era (September 2018-February 2020).Results A total of 1,022 surgeries were done under anesthesia in the COVID period as against 1,710 surgeries done in a similar time frame in the pre-COVID era. Overall, we saw a 40%drop in the total number of cases. Thorax, abdominal, and miscellaneous surgeries (soft tissue sarcomas, urology, and gyneconcology) saw a maximum fall in numbers;however, head and neck cases saw an increase in numbers during the pandemic. Surgical morbidity and mortality were similar in the COVID and pre-COVID era. No cases of severe COVID infection were reported among the healthcare staff working in OT.Discussion We could successfully continue our anesthesia services with minimal risk to healthcare staff throughout the pandemic by adopting major guidelines in a pragmatic and practical approach with minor changes to suit our setup.

Operating performance during the COVID-19 pandemic: Is there a business group advantage?

In this paper, we study whether firms belonging to business groups (BG) have superior operating performance relative to stand-alone firms during the ongoing COVID-19 (COVID) pandemic. Our research is motivated by mixed empirical evidence on the performance of BG-affiliated firms. Using return on equity as a measure of operating performance and a sample of Indian firms, we first show that BG firms have lower ROE than stand-alone firms, on average. We disaggregate ROE into operating profitability (return on net operating assets – RNOA) and financial policy decisions (net borrowing costs – NBC and financial leverage – FFLEV) and show that while BG firms do not experience a significant change in NBC and FLLEV during the pandemic compared to stand-alone firms, relative to pre-COVID times, they experience a significant drop in RNOA. This is driven by much lower sales during the pandemic. Further, the relative decline in BG performance during the pandemic is driven by firms affiliated with smaller BGs, younger BGs, and less diversified BGs. © 2023

Herbal Immunomodulators: A Powerful Preventive Weapon for COVID-19

The Corona Virus Disease of 2019 is characterized by a serious epidemic (COVID-19). The acute respiratory syndrome is caused by the coronavirus, which is followed by an inflammatory response in the host. Systemic inflammatory response syndrome (SIRS) is a condition in which the body causes acute breathing problems, multiple organ impairment disorder, and even in the early stages of multiple organ failure extreme COVID-19. Increased development of anti-inflammatory cytokines in the late stages of serious disease causes the immune system's reaction to becoming controlled, resulting in immune fatigue. Pandemics have wreaked havoc on humanity's strata, wiped out whole nations, and strengthening immunity is long overdue. A strong immune system is needed to fight a viral infection. Multivitamin-rich diets improve pathogen immunity by triggering immune responses in several immune cells, as an example. Various immune-stimulating herbs, plants, and spices like chicory, Tinospora cordifolia, Withania somnifera, myrrh, ginger, etc., must be included to counteract the pathogens. © 2022 by the authors.

Mucormycosis-a Fungal Infection in Patient Recovered from COVID-19

Recently, a fungal disease, "Mucormycosis,” has created a huge fury in everybody's mind. It is prevalent in immunocompromised individuals, such as people suffering from Covid 19, cancer, HIV, prolonged use of steroids, immunomodulators, and diabetes. It is caused by a group of molds called mucoromycetes found in damp soil, bread, decaying fruits and vegetables, compost piles, animal waste, and moist, dusty construction sites. It can invade the human body through several routes, such as inhalation, injury site, or food/water intake. The ICMR recommends wearing a mask while visiting dusty construction sites, wearing shoes, long trousers, a full sleeve shirt, and gloves when handling soils, moss, or manure, and maintaining personal hygiene, including a good scrub bath. This article further covers the history, pathogenesis, role of Iron, GRP78, and CotH, pathophysiology, geographical spread, and treatment of this rare but fatal disease. Overall, the mortality rates account for 54%, which is further varied depending upon the patient condition, type of fungus & body site infected, speaking of which, as reported, 96% mortality rate alone accounts for the disseminated Mucormycosis. © 2021 by the authors.

Trained innate immunity and diseases: Bane with the boon

Emerging research shows that innate immunity can also keep the memory of prior experiences, challenging the long-held notion that immunological memory is only the domain of the adaptive immune cells. However, the absence of immunological memory in innate immune responses has recently been brought into question. Now it is known that after a few transient activations, innate immune cells may acquire immunological memory phenotype, resulting in a stronger response to a subsequent secondary challenge. When exposed to particular microbial and/or inflammatory stimuli, trained innate immunity is characterized by the enhanced non-specific response, which is regulated by substantial metabolic alterations and epigenetic reprogramming. Trained immunity is acquired by two main reprogramming, namely, epigenetic reprogramming and metabolic adaptation/reprogramming. Epigenetic reprogramming causes changes in gene expression and cell physiology, resulting in internal cell signaling and/or accelerated and amplified cytokine release. Metabolic changes due to trained immunity induce accelerated glycolysis and glutaminolysis. As a result, trained immunity can have unfavorable outcomes, such as hyper inflammation and the development of cardiovascular diseases, autoinflammatory diseases, and neuroinflammation. In this review, the current scenario in the area of trained innate immunity, its mechanisms, and its involvement in immunological disorders are briefly outlined.Copyright © 2022

Data Analysis using Robot Process Automation Study on Web Scraping using UI Path Studio

Automation has been into existence since the mid Fifties but had simplest began to gain attention lately. The RPA software program makes use of existing generation's interface to automate the human detail in the technique. So, essentially, there's no want for human intervention. web scraping is a software of robot system Automation that is used in almost all of the industries. either or not it's a e-trade internet site, commodities buying and selling web sites, or any internet site and so forth. you can scrape the information from any of them based on your hobby. Now, the problem with guide scraping by hand is that it's miles at risk of mistakes and takes numerous times. also, the facts available on websites does now not change in any respect. up to date regularly, for this reason facts saved domestically might not usually be terrible. So, industries can actually automate this mission. The main objective of the project is to save time and send the updated information to the person using RPA technology. As this COVID-19 Global Pandemic going on, we thought of creating a project around COVID-19. So, in the project we will use Data Scrapping to extract Web Table (which contains COVID-19 data such as number of affected people, recovered people etc.) from web page. And, write the extracted data into Excel then we will send that excel over the email as attachment. In this project we researched how we can send data through email using RPA and extract the data from live covid_19 website. For software automation, there are many software's that are available in market. The main RPA vendors are UiPath, Automation Anywhere, and Blue Prism. So, to complete our RPA project, we have chosen UiPath which the best in the field of automation. You should be familiar with at least one of these tools before working on the following projects. This paper aims to provide RPA reviews as technical, as well as its implementation applications. © 2022 IEEE.

Diagnostic Approaches for Covid-19: Present Status and Future Prospects

During this COVID-19 outbreak, diagnostic tests were crucial in controlling its spread. This pandemic, which was caused by the SARS-CoV-2 virus, has created an urgent need for rapid diagnostic testing to enable efficient treatment and control of COVID-19. Many institutes and companies are trying to develop effective methods for detecting COVID-19. The essential indicative instrument presently utilized is reverse transcription-polymerase chain response (RT-PCR), which can have great affectability. Tragically, execution costs, time is taken, and false-negative results have limited the use of RT-PCR. Lateral flow assays (LFAs) are a type of diagnostic test that is clinically sensitive enough, might bridge various inadequacies in the present RT-PCR system, especially in low-and middle-income countries. In basic hospitals and laboratories, AuNP-LFA is a viable technique for diagnosing COVID-19, especially in emergency settings where a large number of samples must be examined quickly. This review summarizes the different diagnostic approaches for detecting the SARS-COV-2. This review thus provides guidelines for the scientists and technicians engaged in detecting SARS-COV-2. An accurate and sensitive detection system would enormously benefit in controlling this pandemic. © 2022 by the authors.

Impact of Work from Home During the Pandemic in Saudi Arabia

The unprecedented health situation in the year 2020 and to some extent 2021 has forced most businesses to operate online with people working from home (WFH). Like almost all countries in the world, Saudi Arabia has suffered from the shocking unstable health situation facing the COVID-19 pandemic. This study investigates different WFH impressions and behaviors that Saudi employees have built during the pandemic and how that has changed over time. We have conducted surveys in two different phases among Saudi employees that have come from varied personal and job-related demographics, including different gender, marital status, cities, managerial roles, job sectors and company sizes. Our data provides a good comprehensive coverage along different demographics. Key findings includes that for 75% of the people it was a brand new experience especially for big companies employees, people's performance and satisfaction depended on the sector that they work for and their marital status, while life work split was the top challenge and flexibility was the top advantage. © 2022 IEEE.

Impact on Pharmaceutical Industry due to Sudden Pandemic Attack (COVID-19)

The coronavirus disease (COVID-19) was first detected in Wuhan, China, in the month of December 2019. Further, in March 2020, the COVID-19 epidemic was described by the World Health Organisation (WHO) as a global pandemic. COVID-19 quickly spread around the world in the following months, affecting about 2.5 million individuals by April 2020. World markets, including the pharmaceutical industry, were devastated by this pandemic. Although no specific solution for this emerging infectious disease is currently available, the pharmaceutical industry is helping policymakers meet unmet COVID-19 desires, ranging from research and advancement initiatives on possible prevention methods to the management of the supply chain of drugs in times of crisis. Changes in demand, commodity shortages, contact adjustments, etc., are hindering developments in the mechanism of technology, research and development and are putting an impact on the health market of COVID-19. Other implications of COVID-19 on the physical condition and pharmaceutical market may include acceptance delays, heading to self-sufficiency in the delivery chain, etc. In addition, the pharmaceutical markets are battling to sustain natural consumer flows, as the latest pandemic has had an effect on access to essential drugs at reasonable rates, which is the key priori-ty of all pharmaceutical systems.Copyright © 2022 Bentham Science Publishers.

Pediatric Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2): Clinical Characteristics and Cycle Threshold Value (CT value) of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) of Nasopharyngeal Samples

Introduction: We aimed to characterize epidemiological and clinical characteristics of children and adolescents with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, and to evaluate relationship of cycle threshold value (CT value) of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test (As surrogate marker of viral load) with patient age and severity of infection. Method(s): We retrospectively collected data of children and adolescents admitted in our center from April 2020 to July 2020 with positive RT-PCR test for SARS-CoV-2. Result(s): Total 62 children, with median (IQR) of age 96 (54-122) months and 39 adolescents with median (IQR) of age 19.5 (18.2-20) years were included. 56 (90%) children and 34 (87%) adolescents had history of SARS-CoV-2 positive cases in their family. Only nine (14%) children had associated risk factor for severe SARS-CoV-2 infection. Fever was the commonest symptom which was present in 24 (39%) children and 16 (41%) adolescents. Cough was present in 17 (27%) children and 10 (26%) adolescents. Diarrhea was found in 14 (23%) children and three (8%) adolescents. CT values of RT-PCR test were similar in children and adolescence (p = 0.48). However, asymptomatic children had higher CT values than symptomatic children (p = 0.01). Conclusion(s): Majority of children have asymptomatic or mild SARS-CoV-2 infection with similar CT values in children and adolescents.Copyright © 2022 by author(s).
