ABSTRACT

Purpose: The primary purpose of this research paper is to evaluate e-learning among employees of Information Technology (IT) companies based in Hyderabad, India. Design/methodology/approach: A survey was undertaken among the employees from different IT companies based in Hyderabad, India, to gauge the perception towards e-learning. The participants were selected randomly. The evaluation is based on a few factors: convenience, usefulness, course content, quality, effectiveness and benefits for employees and organizations. The responses were recorded online through a structured questionnaire. In total, 237 responses have been collected for this present study, of which 227 questionnaires were used for analysis. Findings: The surveyed employees perceived that e-learning helped them enhance their workplace competency in a flexible but effective manner. The e-learning also empowered the learners and ultimately contributed to the enhancement of organizational performance in some ways. Research limitations/implications: Limitation of the study – by examining the pris study was confined to employees working with IT companies based in Hyderabad City, India. The data is collected online, and there may be some insufficient responses. Implications of the study – the study results show a deep insight into the critical aspects of e-learning as a tool for employee training for the benefit of employees and organizational development. The surveyed respondents from the IT sector at Hyderabad perceived that keys to successful e-learning programs should give due consideration towards availability of internet bandwidth, making the course more interactive, providing more choices to the learners and user-friendly and personalized learning experience. The study also shows that the e-learning programs primarily benefit the employees as well as the organization in a manner, namely, improved productivity, helping to achieve business objectives of the firm, growth and advancement to the employees and enhancing the job-related knowledge. The study also discovered that e-learning improves employees' opportunities for professional growth and advancement inside and outside the organization by assisting them in learning new skills and enhancing job-related information. Practical implications: The internet penetration in recent years, as well as post-Covid-19, has given rise to online learning in the education and corporate sectors. The emergence of online or e-learning has been gaining ground in the corporate world by replacing the existing face-to-face or physical training model because of the cost factor and flexible learning to the learners. E-learning improves the learner's ability to adapt to the company's constantly changing business environment, which in turn helps the company increase departmental productivity and, ultimately, achieve its overall business goals. Social implications: The e-learning also empowered the learners and ultimately contributed to the enhancement of organizational performance in some ways. The e-learning also empowers the learner to perform better at his workplace and at the same time moving on the social ladder as the learning makes him/her confident at the job market. Originality/value: This study provides a valuable understanding of employee perceptions on the adoption and effectiveness of e-learning, which ultimately improves the benefits of the training and development department in realizing and enhancing the quality in corporate companies. © 2023, Emerald Publishing Limited.

ABSTRACT

In coronavirus disease 2019 (COVID-19) patients, acute tubular injury is the most frequently documented kidney disease. According to the current knowledge, its cause is assumed to be multifactorial. Other kidney diseases observed in non-severely ill COVID-19 patients are thrombotic microangiopathy, necrotizing glomerulonephritis, primary podocytopathy and interstitial nephritis. Even after a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, necrotizing glomerulonephritis and other kidney diseases were observed. It is recommended that a renal biopsy be performed in COVID-19 patients with elevated creatinine, proteinuria, and/or hematuria to rule out a variety of other renal disorders. Both diseases (during a SARS-CoV-2 infection and after vaccination) probably share common features that act as triggers when the patient is preconditioned for a renal disease. The activation of the complement system and the formation of neutrophil extracellular traps (NET) could play a role in the pathogenesis. As the first report on autopsies carried out on COVID-19 patients throughout Germany showed, the autopsy plays a central role for a better understanding of this (relatively) new disease.Copyright © 2022, The Author(s), under exclusive licence to Springer Medizin Verlag GmbH, ein Teil von Springer Nature.

ABSTRACT

Burn camps play a vital role in the recovery of burn survivors by allowing them to develop the confidence and skill sets needed to reintegrate back into society. During the COVID-19 pandemic, burn camps across the United States and Canada could not hold any in-person activities. They had to either pause burn camps or quickly adapt to a virtual online platform. A 37-item electronic survey was developed and emailed to burn camp directors in the United States and Canada to determine what adaptations were necessary during the pandemic. This survey allowed directors to provide details on many facets such as camp format, successes observed, and challenges encountered. Twenty-one of 34 (62%) burn camp organizations completed the survey. 13 of the 21 (62%) respondents held virtual burn camps in 2020 while everyone else canceled their camps in 2020. The mean number of camps offered per organization decreased from 6.3 in 2019 to 4.7 in 2020. The average number of burn survivors and family members participating also dropped in that same period (2019 aggregate mean = 229.2 vs. 2020 aggregate mean = 151.4). Components of virtual camp included video conferencing platforms, "camp in a box" activities, and some prerecorded sessions. Most camp directors believed that their campers were satisfied with the virtual format. Factors allowing for a successful virtual camp included an effective online platform, scheduling adequate duration of programs, and appropriate staffing levels. Most common barriers to an effective virtual camp were participant engagement, special needs/accessibility concerns, and staff effectiveness in this format. While challenging, burn camps can be held in a virtual format successfully with proper planning, staff training, and support of campers and their families.

ABSTRACT

BACKGROUND: We hypothesised that zanubrutinib, a highly selective next-generation Bruton tyrosine kinase (BTK) inhibitor, would be a safe and active treatment for patients intolerant of ibrutinib, acalabrutinib, or both. We aimed to assess whether zanubrutinib would prolong treatment duration by minimising treatment-related toxicities and discontinuations in patients with previously treated B-cell malignancies. METHODS: This ongoing, phase 2, multicentre, open-label, single-arm study was done in 20 centres in the USA. Patients aged 18 or older with previously treated B-cell malignancies (chronic lymphocytic leukaemia, small lymphocytic lymphoma, mantle cell lymphoma, Waldenström macroglobulinaemia, or marginal zone lymphoma) who became intolerant of ibrutinib, acalabrutinib, or both, were orally administered zanubrutinib 160 mg twice daily or 320 mg once daily per investigator. The primary endpoint was recurrence and change in severity of ibrutinib or acalabrutinib intolerance events based on investigator-assessed adverse events. Secondary endpoints were investigator-assessed overall response rate; duration of response; disease control rate; and progression-free survival. Analyses included all patients who received any dose of the study drug. This study is registered with ClinicalTrials.gov, NCT04116437. FINDINGS: Between Oct 14, 2019, and Sept 8, 2021, 67 patients (36 [54%] men and 31 [46%] women) who were intolerant of ibrutinib (n=57; cohort 1) or of acalabrutinib or acalabrutinib and ibrutinib (n=10; cohort 2) were enrolled. 63 (94%) patients were White, one (2%) had multiple ethnicities, and three (5%) had unreported or unknown ethnicity. Most intolerance events (81 [70%] of 115 for ibrutinib; 15 [83%] of 18 for acalabrutinib) did not recur with zanubrutinib. Of the recurring events, seven (21%) of 34 ibrutinib intolerance events and two (67%) of three acalabrutinib intolerance events recurred at the same severity with zanubrutinib; 27 (79%) ibrutinib intolerance events and one (33%) acalabrutinib intolerance event recurred at a lower severity with zanubrutinib. No events recurred at higher severity. No grade 4 intolerance events recurred. 64 (96%) of 67 patients had one or more adverse events with zanubrutinib; the most common adverse events were contusion (in 15 [22%] of 67 patients), fatigue (14 [21%]), myalgia (ten [15%]), arthralgia (nine [13%]), and diarrhoea (nine [13%]). Atrial fibrillation occurred in three (4%) patients (all grade 2). Eight (12%) of 67 patients had serious adverse events (anaemia, atrial fibrillation, bronchitis, COVID-19, COVID-19 pneumonia, febrile neutropenia, salmonella gastroenteritis, transfusion reaction, trigeminal nerve disorder, and urinary tract infection). No treatment-related deaths occurred. The median follow-up time was 12·0 months (IQR 8·2-15·6). Among the 64 efficacy-evaluable patients, disease control rate was 93·8% (60; 95% CI 84·8-98·3) and overall response rate was 64·1% (41; 95% CI 51·1-75·7). The median duration of response was not reached; the 12-month event-free duration of response rate was 95·0% (95% CI 69·5-99·3). Similarly, median progression-free survival was not reached; 18-month progression-free survival was 83·8% (95% CI 62·6-93·6). INTERPRETATION: Patients intolerant of previous BTK inhibitors have limited treatment options. These results suggest that zanubrutinib, a safe and viable treatment for patients with B-cell malignancies, might fill that unmet need for those who exhibit intolerance to ibrutinib or acalabrutinib.

ABSTRACT

Excessive inflammation is a major cause of morbidity and mortality in many viral infections including influenza. Therefore, there is a need for therapeutic interventions that dampen and redirect inflammatory responses and, ideally, exert antiviral effects. Itaconate is an immunomodulatory metabolite which also reprograms cell metabolism and inflammatory responses when applied exogenously. We evaluated effects of endogenous itaconate and exogenous application of itaconate and its variants dimethyl- and 4-octyl-itaconate (DI, 4OI) on host responses to influenza A virus (IAV). Infection induced expression of ACOD1, the enzyme catalyzing itaconate synthesis, in monocytes and macrophages, which correlated with viral replication and was abrogated by DI and 4OI treatment. In IAV-infected mice, pulmonary inflammation and weight loss were greater in Acod1-/- than in wild-type mice, and DI treatment reduced pulmonary inflammation and mortality. The compounds reversed infection-triggered interferon responses and modulated inflammation in human cells supporting non-productive and productive infection, in peripheral blood mononuclear cells, and in human lung tissue. All three itaconates reduced ROS levels and STAT1 phosphorylation, whereas AKT phosphorylation was reduced by 4OI and DI but increased by itaconate. Single-cell RNA sequencing identified monocytes as the main target of infection and the exclusive source of ACOD1 mRNA in peripheral blood. DI treatment silenced IFN-responses predominantly in monocytes, but also in lymphocytes and natural killer cells. Ectopic synthesis of itaconate in A549 cells, which do not physiologically express ACOD1, reduced infection-driven inflammation, and DI reduced IAV- and IFNγ-induced CXCL10 expression in murine macrophages independent of the presence of endogenous ACOD1. The compounds differed greatly in their effects on cellular gene homeostasis and released cytokines/chemokines, but all three markedly reduced release of the pro-inflammatory chemokines CXCL10 (IP-10) and CCL2 (MCP-1). Viral replication did not increase under treatment despite the dramatically repressed IFN responses. In fact, 4OI strongly inhibited viral transcription in peripheral blood mononuclear cells, and the compounds reduced viral titers (4OI>Ita>DI) in A549 cells whereas viral transcription was unaffected. Taken together, these results reveal itaconates as immunomodulatory and antiviral interventions for influenza virus infection.

ABSTRACT

Blended learning is an adaptive (and necessary) response adopted by most universities to face the challenges posed by the COVID-19 ongoing pandemic. Academic Learning Management Systems (ALMSs) played a strategic and pivotal role under high pressure. Online learning can occur by implementing integrated solutions embedded in the Academic portals or subscriptions to other videoconferencing solutions. Blending online and face-to-face teaching proved challenging from different perspectives. This approach has been considered essential to ensure an adequate level of service and avoid outflows of students, but it led to increased teaching workload, improved infrastructure, flexible pedagogic approach, enhanced technologies, specific training, and IT solutions development. The authors perform a SWOT analysis of blended learning, in a transnational Higher Education Context, to match the findings with the most relevant and critical challenges. The results, therefore, support the Information System analysis, focusing on one of the most widespread ALMSs. The case of Blackboard is finally considered, and some implementations are suggested. © 2022 Association for Computing Machinery. All rights reserved.

ABSTRACT

Objective: This study aimed to compare the symptoms and the severity of the illness among positive Coronavirus Disease 2019 (COVID-19) high-risk individuals with or without the prophylactic use of hydroxychlo-roquine (HCQ). Methods: This cross-sectional study was conducted at the Pakistan Institute of Medical Sciences (PIMS), Islamabad. A total of 485 high-risk individuals with possible exposure to COVID-19 were enrolled in the study. The data were collected through a pre-designed self-repor ting questionnaire inquiring about the individual's history, baseline characteristics, COVID-19 associated risk factors, exposure history, polymerase chain reaction (PCR) and antibody screening results, HCQ drug dosage, and adverse effects. The COVID-19 symptoms and the severity of the illness were also recorded. The individuals were divided into two groups as per the HCQ intake, i.e. users and non-users, and compared for statistical significance. The data of 121 PCR positive COVID-19 individuals were also compared between the two groups. Results: Out of 485 individuals, 264 (54.4%) were HCQ users. All the study demographics were comparable in both study groups. The study revealed that the COVID-19 positive cases were significantly less reported in the HCQ user group than in the non-HCQ user group (40.3% vs. 58.5%;P-value = 0.004). Of these 121 COVID-19 positive cases, shortness of breath (11.6%), anosmia (13%) and the severity of the illness requiring hospitalization (14.5%) were profound among non-HCQ users as compared to those who were prophylactically receiving HCQ. No serious side-effects were reported by the HCQ users. Conclusion: Voluntary pre-exposure HCQ administration significantly reduces the severity of illness, both symptomatic and radiological, among COVID-19 positive individuals.

ABSTRACT

Background During the coronavirus disease 2019 pandemic, three-dimensional (3D) printing was utilized to rapidly produce face shields for frontline workers in response to an acute shortage of personal protective equipment (PPE). In this study, we examine the perceived utility and performance of 3D-printed (3DP) face shields through a survey of frontline workers in Ontario, Canada. Methodology Frontline workers who received community-produced 3DP face shields from the Canadian initiative “3DPPE GTHA” (March-December 2020) were invited to participate in the study. The survey response rate was 54.3%. Of 63 respondents, 39 were patient-facing and 24 were community-facing frontline workers. Participants were asked to rate performance measures in 10 categories on a five-point Likert scale. Data were categorized by organization and frontline worker type, and a t-test was used to determine statistically significant differences among subgroups. Results The mean preference for 3DP face shields among respondents was 3.2 out of 5 (95% confidence interval [CI]: 2.1-4.3). Community-facing respondents reported significantly greater overall utility scores for 3DP face shields (3.58, 95% CI: 3.38-3.79) compared to respondents working in a patient-facing profession (2.95, 95% CI: 2.77-3.13;p < 0.05). However, no differences were reported in portability and compatibility with other PPE. Respondents from organizations with large service volumes reported significantly lower overall utility scores (2.67, 95% CI: 2.44-2.89) than respondents in organizations with smaller service volumes (3.45, 95% CI: 3.28-3.62;p < 0.05). Conclusions Community-facing frontline workers and those from smaller service volume organizations endorse higher utility for 3DP face shields than patient-facing frontline workers. Despite this, frontline workers generally rate 3DP face shields positively. 3DP face shields are a viable option for personal and community use and can be used to supplement supply in a community setting.

ABSTRACT

A novel virus is discovered recently, named as Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). It causes the Coronavirus Disease 2019 (COVID-19), which is spreading rapidly worldwide. The emerging genetics and clinical evidence of the SARS-CoV-2 virus suggest a similar path to those of Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). Coronavirus causes respiratory illness in humans and infect several other species of animals. It was one of the best interests of researchers as it attracted virologist's attention in last two decades. It was clear from an epidemic in 2002-2003 of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) that human civilization may have animal coronavirus as its potential threat in the future. However, the mechanism of this virus spreading from one specie to another remained obscure these years. The 2012 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) epidemic of animals, and now this COVID-19 pandemic prioritizes the human coronavirus for further research and exploration. However, General hygiene, social distancing, and disinfection can prevent the person-to-person spread of coronavirus. This review focuses on SARS-CoV-2, which is emerged from China in December 2019 and caused a novel disease named as COVID-19. The current review has an insight to possible treatment COVID-19 followed by a short review of In silico candidate drug design and prevention;This systematic review was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Databases, including Health Research and Development Information network Plus (HERDIN Plus), Science direct, PubMed and google scholar were visited to search the articles. Further, the forecasting results of the fitted model show a significant decrease in the weekly global deaths from the 51th week of 2020 16th week of 2021 but 95% limit has also shown the potential of getting the situation worser amid COVID-19 second wave.

ABSTRACT

Introduction: Multiple risk factors of mortality have been identified in patients with COVID-19. Here, we sought to determine the effect of a history of neurological disorder and development of neurological manifestations on mortality in hospitalized patients with COVID-19. Methods: From March 20 to May 20, 2020, hospitalized patients with laboratory confirmed or highly suspected COVID-19 were identified at four hospitals in Ohio. Previous history of neurological disease was classified by severity (major or minor). Neurological manifestations during disease course were also grouped into major and minor manifestations. Encephalopathy, ischemic or hemorrhagic stroke, and seizures were defined as major manifestations, whereas minor neurological manifestations included headache, anosmia, dysgeusia, dizziness or vertigo, and myalgias. Multivariate logistic regression models were used to determine significant predictors of mortality in patients with COVID-19 infection. Results: 574/626 hospitalized patients were eligible for inclusion. Mean age of the 574 patients included in the analysis was 62.8 (SD 17.6), with 298 (51.9%) women. Of the cohort, 240(41.8%) patients had a prior history of neurological disease (HND), of which 204 (35.5%) had a major history of neurological disease (HND). Mortality rates were higher in patients with a major HND (30.9 vs. 15.4%; p = 0.00002), although this was not a significant predictor of death. Major neurological manifestations were recorded in 203/574 (35.4%) patients during disease course. The mortality rate in patients who had major neurological manifestations was 37.4% compared to 11.9% (p = 2 × 10-12) in those who did not. In multivariate analysis, major neurological manifestation (OR 2.1, CI 1.3-3.4; p = 0.002) was a predictor of death. Conclusions: In this retrospective study, history of pre-existing neurological disease in hospitalized COVID-19 patients did not impact mortality; however, development of major neurological manifestations during disease course was found to be an independent predictor of death. Larger studies are needed to validate our findings.

ABSTRACT

Humans have witnessed three deadly pandemics so far in the twenty-first century which are associated with novel coronaviruses: SARS, Middle East respiratory syndrome (MERS), and COVID-19. All of these viruses, which are responsible for causing acute respiratory tract infections (ARTIs), are highly contagious in nature and/or have caused high mortalities. The recently emerged COVID-19 disease is a highly transmittable viral infection caused by another zoonotic novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Similar to the other two coronaviruses such as SARS-CoV-1 and MERS-CoV, SARS-CoV-2 is also likely to have originated from bats, which have been serving as established reservoirs for various pathogenic coronaviruses. Although, it is still unknown how SARS-CoV-2 is transmitted from bats to humans, the rapid human-to-human transmission has been confirmed widely. The disease first appeared in Wuhan, China, in December 2019 and quickly spread across the globe, infected 48,539,872 people, and caused 1,232,791 deaths in 215 countries, and the infection is still spreading at the time of manuscript preparation. So far, there is no definite line of treatment which has been approved or vaccine which is available. However, different types of potential vaccines and therapeutics have been evaluated and/or are under clinical trials against COVID-19. In this review, we summarize different types of acute respiratory diseases and briefly discuss earlier outbreaks of coronaviruses and compare their occurrence and pathogenicity with the current COVID-19 pandemic. Various epidemiological aspects of COVID-19 such as mode of spread, death rate, doubling time, etc., have been discussed in detail. Apart from this, different technical issues related to the COVID-19 pandemic including use of masks and other socio-economic problems associated with the pandemic have also been summarized. Additionally, we have reviewed various aspects of patient management strategies including mechanism of action, available diagnostic tools, etc., and also discussed different strategies for the development of effective vaccines and therapeutic combinations to deal with this viral outbreak. Overall, by the inclusion of various references, this review covers, in detail, the most important aspects of the COVID-19 pandemic.

ABSTRACT

: This combined American Neurotology Society, American Otological Society, and American Academy of Otolaryngology - Head and Neck Surgery Foundation document aims to provide guidance during the coronavirus disease of 2019 (COVID-19) on 1) "priority" of care for otologic and neurotologic patients in the office and operating room, and 2) optimal utilization of personal protective equipment. Given the paucity of evidence to inform otologic and neurotologic best practices during COVID-19, the recommendations herein are based on relevant peer-reviewed articles, the Centers for Disease Control and Prevention COVID-19 guidelines, United States and international hospital policies, and expert opinion. The suggestions presented here are not meant to be definitive, and best practices will undoubtedly change with increasing knowledge and high-quality data related to COVID-19. Interpretation of this guidance document is dependent on local factors including prevalence of COVID-19 in the surgeons' local community. This is not intended to set a standard of care, and should not supersede the clinician's best judgement when managing specific clinical concerns and/or regional conditions.Access to otologic and neurotologic care during and after the COVID-19 pandemic is dependent upon adequate protection of physicians, audiologists, and ancillary support staff. Otolaryngologists and associated staff are at high risk for COVID-19 disease transmission based on close contact with mucosal surfaces of the upper aerodigestive tract during diagnostic evaluation and therapeutic procedures. While many otologic and neurotologic conditions are not imminently life threatening, they have a major impact on communication, daily functioning, and quality of life. In addition, progression of disease and delay in treatment can result in cranial nerve deficits, intracranial and life-threatening complications, and/or irreversible consequences. In this regard, many otologic and neurotologic conditions should rightfully be considered "urgent," and almost all require timely attention to permit optimal outcomes. It is reasonable to proceed with otologic and neurotologic clinic visits and operative cases based on input from expert opinion of otologic care providers, clinic/hospital administration, infection prevention and control specialists, and local and state public health leaders. Significant regional variations in COVID-19 prevalence exist; therefore, physicians working with local municipalities are best suited to make determinations on the appropriateness and timing of otologic and neurotologic care.

ABSTRACT

ObjectivesPakistan has a high infectious disease burden with about 265,000 reported cases of COVID-19. We investigated the genomic diversity of SARS-CoV-2 strains and present the first data on viruses circulating in the country. MethodsWe performed whole-genome sequencing and data analysis of SARS-CoV-2 eleven strains isolated in March and May. ResultsStrains from travelers clustered with those from China, Saudi Arabia, India, USA and Australia. Five of eight SARS-CoV-2 strains were GH clade with Spike glycoprotein D614G, Ns3 gene Q57H, and RNA dependent RNA polymerase (RdRp) P4715L mutations. Two were S (ORF8 L84S and N S202N) and three were L clade and one was an I clade strain. One GH and one L strain each displayed Orf1ab L3606F indicating further evolutionary transitions. ConclusionsThis data reveals SARS-CoV-2 strains of L, G, S and I have been circulating in Pakistan from March, at the start of the pandemic. It indicates viral diversity regarding infection in this populous region. Continuing molecular genomic surveillance of SARS-CoV-2 in the context of disease severity will be important to understand virus transmission patterns and host related determinants of COVID-19 in Pakistan.

ABSTRACT

The current coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 has led to immense strain on healthcare systems and workers. Patients with severe symptoms of COVID-19 may also present with acute neurological emergencies such as ischemic stroke. Ischemic stroke in these patients may result from COVID-19 related complications or decompensation of previously asymptomatic cerebrovascular disorders, or concurrent ischemic stroke from common stroke risk factors in a patient with COVID-19. Acute ischemic stroke patients with large vessel occlusions require emergent triage, intensive care, and mechanical thrombectomy. Management of patients with large vessel occlusions (LVO) requires special considerations in the current pandemic. Physicians must now account for prognosis of severe COVID-19, resource utilization, and risk of infection to healthcare workers when determining eligibility for mechanical thrombectomy (MT). Here, we describe important prognostic factors including age, laboratory, and imaging findings to consider for MT selection and provide suggestions for taking care of patients with LVO and possible or confirmed COVID-19. It is recommended to perform MT in patients within the established guidelines, and consider a conservative approach in cases where there is clinical equipoise to minimize futile reperfusion. Lastly, we describe an illustrative case of a patient with ischemic stroke and COVID-19.
