ABSTRACT

There is currently a lack of studies on residential waste collection during COVID-19 in North America. SARIMA models were developed to predict residential waste collection rates (RWCR) across four North American jurisdictions before and during the pandemic. Unlike waste disposal rates, RWCR is relatively less sensitive to the changes in COVID-19 regulatory policies and administrative measures, making RWCR more appropriate for cross-jurisdictional comparisons. It is hypothesized that the use of RWCR in forecasting models will help us to better understand the residential waste generation behaviors in North America. Both SARIMA models performed satisfactorily in predicting Regina's RWCR. The SARIMA DCV model's performance is noticeably better during COVID-19, with a 15.7% lower RMSE than that of the benchmark model (SARIMA BCV). The skewness of overprediction ratios was noticeably different between jurisdictions, and modeling errors were generally lower in less populated cities. Conflicting behavioral changes might have altered the residential waste generation characteristics and recycling behaviors differently across the jurisdictions. Overall, SARIMA DCV performed better in the Canadian jurisdiction than in U.S. jurisdictions, likely due to the model's bias on a less variable input dataset. The use of RWCR in forecasting models helps us to better understand the residential waste generation behaviors in North America and better prepare us for a future global pandemic.

ABSTRACT

SARS-CoV-2 is the foremost culprit of the novel coronavirus disease 2019 (nCoV-19 and/or simply COVID-19) and poses a threat to the continued life of humans on the planet and create pandemic issue globally. The 3-chymotrypsin-like protease (MPRO or 3CLPRO) is the crucial protease enzyme of SARS-CoV-2, which directly involves the processing and release of translated non-structural proteins (nsps), and therefore involves the development of virus pathogenesis along with outbreak the forecasting of COVID-19 symptoms. Moreover, SARS-CoV-2 infections can be inhibited by plant-derived chemicals like amentoflavone derivatives, which could be used to develop an anti-COVID-19 drug. Our research study is designed to conduct an in silico analysis on derivatives of amentoflavone (isoginkgetin, putraflavone, 4''''''-methylamentoflavone, bilobetin, ginkgetin, sotetsuflavone, sequoiaflavone, heveaflavone, kayaflavone, and sciadopitysin) for targeting the non-structural protein of SARS-CoV-2, and subsequently further validate to confirm their antiviral ability. To conduct all the in silico experiments with the derivatives of amentoflavone against the MPRO protein, both computerized tools and online servers were applied; notably the software used is UCSF Chimera (version 1.14), PyRx, PyMoL, BIOVIA Discovery Studio tool (version 4.5), YASARA (dynamics simulator), and Cytoscape. Besides, as part of the online tools, the SwissDME and pKCSM were employed. The research study was proposed to implement molecular docking investigations utilizing compounds that were found to be effective against the viral primary protease (MPRO). MPRO protein interacted strongly with 10 amentoflavone derivatives. Every time, amentoflavone compounds outperformed the FDA-approved antiviral medicine that is currently underused in COVID-19 in terms of binding affinity (- 8.9, - 9.4, - 9.7, - 9.1, - 9.3, - 9.0, - 9.7, - 9.3, - 8.8, and - 9.0 kcal/mol, respectively). The best-selected derivatives of amentoflavone also possessed potential results in 100 ns molecular dynamic simulation (MDS) validation. It is conceivable that based on our in silico research these selected amentoflavone derivatives more precisely 4''''''-methylamentoflavone, ginkgetin, and sequoiaflavone have potential for serving as promising lead drugs against SARS-CoV-2 infection. In consequence, it is recommended that additional in vitro as well as in vivo research studies have to be conducted to support the conclusions of this current research study.

ABSTRACT

Lumpy skin disease (LSD) is a viral disease that affects farm animals including water buffalo. It is caused by the contagious LSD virus, a member of the Poxiviridae family's Capripox genus. Skin sores are thought to be the most common site of infection since the virus may live for lengthy periods in lesions or scabs. The first clinical indications of LSD were described in Zambia, in 1929. Pakistan has also been afflicted by LSD, with a high number of animals infected at many cattle ranches in Karachi, 190,000 cases of LSD have been reported nationwide, with greater than 7500 deaths attributable to the illness. LSD has a huge influence on Pakistan's economic status, resulting in the loss of cattle and a decrease in milk output. The Ministry of Research and National Food Safety in Pakistan has formed a working group to create a framework for controlling the spread of LSD in cattle and buffalo. Official and private veterinarians, both field and slaughterhouse, veterinary students, farmers, cattle merchants, cattle truck drivers, and artificial inseminators should all participate in awareness efforts.

ABSTRACT

Over 1.5 million units of blood are collected in Pakistan each year, with around 65% of this donation coming from replacement donors-relatives or close friends of the affected who willingly donate blood to support the patient. Although blood transfusion is a life-saving therapy, it also involves the danger of spreading blood-borne illnesses if not appropriately screened. It has been extensively discussed that the precise number of transfusion transmitted infections (TTIs) in the Pakistani population is still unclear, and the estimates reported by the Sindh Blood Transfusion Authority may be a major underestimation because of the country's lack of inexpensive and effective screening tests. Regular blood transfusions are the mainstay of treatment of patients with blood diseases such as thalassemia and anemia. They are also commonly used to handle acute injuries, surgery, bleeding, and birthing difficulties. However, the risk of getting a TTI results in an increased hesitancy among blood transfusion recipients. Hence, to reduce the occurrence of TTIs, effective and vigorous measures must be implemented.

ABSTRACT

The widespread prevalence of fungal infections in the second wave of COVID-19 pandemic could be owed to ubiquitous and injudicious use of steroids and immunosuppressive nature of the virus. However, these fungal infections also meant increased use of antifungal drugs, hence endangering their supply. Amphotericin B is the first line drug for mucormycosis which was declared as an epidemic in India during the second wave. With the increasing demand of the drug, came challenges to manufacture and supply large quantities of the drug and exploitation by creating a black market and spread of false information and imprudent usage. It is of utmost importance to be prepared with adequate supply all over the nation and implementing safety regulations in manufacturing and supply of large quantities of drugs during the demanding times and make them accessible at a reasonable rate.

ABSTRACT

COVID-19 is a contagious viral infection caused by severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2). One of the key features of COVID-19 infection is inflammation. There is increasing evidence pointing to an association between cytokine storm and autoimmunity. One autoimmune disease of interest in connection to COVID-19 is hyperthyroidism. COVID-19 has been shown to decrease TSH levels and induce thyrotoxicosis, destructive thyroiditis, and de novo Graves' disease. It has also been suggested that the immune response against SARS-CoV-2 antigens following vaccination can cross-react through a mechanism called molecular mimicry which can elicit autoimmune reactivity, potentially leading to potential thyroid disease post vaccine. However, if the COVID-19 vaccine is linked to reduced COVID-19 related serious disease, it could potentially play a protective role against post COVID-19 hyperthyroidism (de novo disease and exacerbations). Further studies investigating the complex interplay between COVID-19 or COVID-19 vaccine and thyroid dysfunction can help provide substantial evidence and potential therapeutic targets that can alter prognosis and improve COVID-19 related outcomes in individuals with or without preexisting thyroid disease.

ABSTRACT

After the widespread of COVID-19 virus worldwide, vaccination targeted reducing spread of cases and mortality rates. However, vaccination hesitancy was observed among the communities worldwide. Vaccination hesitancy involved parents regarding the decision of vaccinating their children- After obtaining ethical approval, an online cross-sectional study was conducted from 1 March to 22 April 2021 to evaluate the parents' acceptance of vaccinating their children against the COVID-19 virus in Syria. Data were analyzed using descriptive and multivariate logistic regression analysis in IBM, SPSS V. 28.0 package program (IBM Corporation, Armonk, NY, USA). Among 283 participants, 105 participants agreed to vaccinate their children, and 178 were not. A significant correlation between age and vaccine willingness was found (P-value < 0.0001*), especially in the age group between 18 and 30 years old (45.2%). Parents who accepted vaccinating themselves were more willing to vaccinate their children (34.6%). According to our results, there is a greater need to enhance awareness and knowledge programs about the vaccine's effectiveness and encourage parents to accept giving the vaccine to their children.

ABSTRACT

The field of teleradiology has been of interest for almost 55 years and its potential prospects for healthcare have been constantly assessed and investigated. In view of the global preventive measures, such as social distancing and hand hygiene, the ongoing COVID-19 pandemic has further accentuated the necessity for telemedicine and teleradiology. In a country as densely populated as India wherein radiology services are often fragmented, teleradiology can prove to be a lifesaving technology and aid dampen the repercussions stemming from the highly skewed doctor to patient ratio. Although innovative, the effective adoption of teleradiology faces several obstacles in India, such as inadequate technological infrastructure, a lack of knowledge among most medical practitioners, urban-rural disparities and a lack of financing. Similar challenges continue to also be faced by several other developing countries across the globe. This article therefore aims to elaborate on the most important facets of implementation of teleradiology observed in the Indian context to help provide salient pointers for the readership of relevant jurisdictions who may be embracing comparable teleradiology challenges. Despite the hurdles, the future of teleradiology seems promising. The respective governments, policymakers and all relevant stakeholders must continue to take decisive action to ensure that this potential is fully exploited by allocation of necessary funds, strengthening of information technology and its related fields, involvement of human resources with adequate technical and administrative expertise as well as taking continued action to improve existing telemedicine and teleradiology services.

ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has brought fundamental changes to our problems and priorities, especially those related to the healthcare sector. India was one of the countries severely affected by the harsh consequences of the COVID-19 pandemic. AIM: To understand the challenges faced by the healthcare system during a pandemic. METHODS: The literature search for this review was conducted using PubMed, EMBASE, Scopus, Web of Science, and Google Scholar. We also used Reference Citation Analysis (RCA) to search and improve the results. We focused on the published scientific articles concerned with two major vital areas: (1) The Indian healthcare system; and (2) COVID-19 pandemic effects on the Indian healthcare system. RESULTS: The Indian healthcare system was suffering even before the pandemic. The pandemic has further stretched the healthcare services in India. The main obstacle in the healthcare system was to combat the rising number of communicable as well as noncommunicable diseases. Besides the pandemic measures, there was a diversion of focus of the already established healthcare services away from the chronic conditions and vaccinations. The disruption of the vaccination services may have more severe short and long-term consequences than the pandemic's adverse effects. CONCLUSION: Severely restricted resources limited the interaction of the Indian healthcare system with the COVID-19 pandemic. Re-establishment of primary healthcare services, maternal and child health services, noncommunicable diseases programs, National Tuberculosis Elimination Program, etc. are important to prevent serious long-term consequences of this pandemic.

ABSTRACT

Alzheimer's disease (AD) is a severe neurodegenerative disorder of the brain that manifests as dementia, disorientation, difficulty in speech, and progressive cognitive and behavioral impairment. The emerging therapeutic approach to AD management is the inhibition of ß-site APP cleaving enzyme-1 (BACE1), known to be one of the two aspartyl proteases that cleave ß-amyloid precursor protein (APP). Studies confirmed the association of high BACE1 activity with the proficiency in the formation of ß-amyloid-containing neurotic plaques, the characteristics of AD. Only a few FDA-approved BACE1 inhibitors are available in the market, but their adverse off-target effects limit their usage. In this paper, we have used both ligand-based and target-based approaches for drug design. The QSAR study entails creating a multivariate GA-MLR (Genetic Algorithm-Multilinear Regression) model using 552 molecules with acceptable statistical performance (R 2 = 0.82, Q 2 loo = 0.81). According to the QSAR study, the activity has a strong link with various atoms such as aromatic carbons and ring Sulfur, acceptor atoms, sp2-hybridized oxygen, etc. Following that, a database of 26,467 food compounds was primarily used for QSAR-based virtual screening accompanied by the application of the Lipinski rule of five; the elimination of duplicates, salts, and metal derivatives resulted in a truncated dataset of 8,453 molecules. The molecular descriptor was calculated and a well-validated 6-parametric version of the QSAR model was used to predict the bioactivity of the 8,453 food compounds. Following this, the food compounds whose predicted activity (pKi) was observed above 7.0 M were further docked into the BACE1 receptor which gave rise to the Identification of 4-(3,4-Dihydroxyphenyl)-2-hydroxy-1H-phenalen-1-one (PubChem I.D: 4468; Food I.D: FDB017657) as a hit molecule (Binding Affinity = -8.9 kcal/mol, pKi = 7.97 nM, Ki = 10.715 M). Furthermore, molecular dynamics simulation for 150 ns and molecular mechanics generalized born and surface area (MMGBSA) study aided in identifying structural motifs involved in interactions with the BACE1 enzyme. Molecular docking and QSAR yielded complementary and congruent results. The validated analyses can be used to improve a drug/lead candidate's inhibitory efficacy against the BACE1. Thus, our approach is expected to widen the field of study of repurposing nutraceuticals into neuroprotective as well as anti-cancer and anti-viral therapeutic interventions.

ABSTRACT

The COVID-19 pandemic had a significant impact on several aspects of global healthcare systems, particularly surgical services. New guidelines, resource scarcity, and an ever-increasing demand for care have posed challenges to healthcare professionals, resulting in the cancellation of many surgeries, with short and long-term consequences for surgical care and patient outcomes. As the pandemic subsides and the healthcare system attempts to reestablish a sense of normalcy, surgical recommendations and advisories will shift. These changes, combined with a growing case backlog (postponed surgeries + regularly scheduled surgeries) and a physician shortage, can have serious consequences for physician health and, as a result, surgical care. Several initiatives are already being implemented by governments to ensure a smooth transition as surgeries resume. Newer and more efficient steps aimed at providing adequate surgical care while preventing physician burnout, on the other hand, necessitate a collaborative effort from governments, national medical boards, institutions, and healthcare professionals. This perspective aims to highlight alterations in surgical recommendations over the course of the pandemic and how these changes continue to influence surgical care and patient outcomes as the pandemic begins to soften its grip.

ABSTRACT

Obesity affects over 650 million adults worldwide and increases the risk of cardiovascular events, diabetes, and hypertension. While lifestyle recommendations are popular management options, bariatric surgery has emerged as a standard of care in refractory cases, reported to cause at least a 30% reduction in mortality. In addition, it mitigates obesity-related complications leading to a significant improvement in the quality of life for morbidly obese patients (BMI >40). Despite the numerous benefits, demand and access to bariatric surgery vary across different demographics such as age, gender, and socioeconomic status. This demand and access were further reduced due to the COVID-19 pandemic. This has resulted in cancellations of elective surgeries such as weight loss procedures and promotes a sedentary lifestyle which has short-term and long-term detrimental consequences on the health of obese patients. In the context of the prevalent epidemiological trends, this reduction in bariatric services will disproportionately affect the elderly, males, low SES, and African Americans. This editorial highlights the prevalent discrepancies in demand and access to bariatric surgery amidst the COVID-19 pandemic, and possible recommendations to improve overall access and utilization of bariatric services in morbidly obese patients belonging to all demographics.

ABSTRACT

Recently, in Pakistan, several cases of mysterious dengue-like illness are being reported, which has concerned the authorities and requires prompt action. We present a case of a 52-year-old female patient presenting with a history of continuous fever, documented up to 104 F, for 5 days. The symptoms were associated with headache, nausea, retro-orbital headache, arthralgia, and myalgia. Currently, to the best of our knowledge, this is the first reported case in the literature for the endemic mysterious virus and may serve as the groundwork for future studies.
