ABSTRACT

Furin, a pro-protein convertase, plays a significant role as a biological scissor in bacterial, viral, and even mammalian substrates which in turn decides the fate of many viral and bacterial infections along with the numerous ailments caused by cancer, diabetes, inflammations, and neurological disorders. In the wake of the current pandemic caused by the virus SARS-CoV-2, furin has become the center of attraction for researchers as the spike protein contains a polybasic furin cleavage site. In the present work, we have searched for novel inhibitors against this interesting human target from FDA-approved antiviral. To enhance the selection of new inhibitors, we employed Kohonen's artificial neural network-based self-organizing maps for ligand-based virtual screening. Promising results were obtained which can help in drug repurposing and network pharmacology studies can address the errors generated due to promiscuity/polypharmacology. We found 15 existing FDA antiviral drugs having the potential to inhibit furin. Among these, six compounds have targets on important human proteins (LDLR, FCGR1A, PCK1, TLR7, DNA, and PNP). The role of these 15 drugs inhibiting furin can be established by studying further on patients infected with number of viruses including SARS-CoV-2. Here we propose two promising candidate FDA drugs GS-441524 and Grazoprevir (MK-5172) for repurposing as inhibitors of furin. The best results were observed with GS-441524.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic necessitated using telehealth to bridge the clinical gap, but could increase health disparities. This article reports on a chart review of diabetes telehealth visits occurring before COVID-19, during shelter-in-place orders, and during the reopening period. Visits for children with public insurance and for those who were non-English speaking were identified. Telehealth visits for children with public insurance increased from 26.2% before COVID-19 to 37.3% during shelter-in-place orders and 34.3% during reopening. Telehealth visits for children who were non-English speaking increased from 3.5% before COVID-19 to 17.5% during shelter-in-place orders and remained at 15.0% during reopening. Pandemic-related telehealth expansion included optimization of workflows to include patients with public insurance and those who did not speak English. Increased participation by those groups persisted during the reopening phase, indicating that prioritizing inclusive telehealth workflows can reduce disparities in access to care.

ABSTRACT

The new severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) is the etiological agent of Coronavirus disease 2019 (COVID-19), which becomes an eventual pandemic outbreak. Lack of proper therapeutic management has accelerated the researchers to repurpose existing drugs with known preclinical and toxicity profiles, which can easily enter Phase 3 or 4 or can be used directly in clinical settings. Vitamins are necessary nutrients for cell growth, function, and development. Furthermore, they play an important role in pathogen defence via cell-mediated responses and boost immunity. Using a computational approach, we intend to identify the probable inhibitory effect of all vitamins on the drug targets of COVID-19. The computational analysis demonstrated that vitamin B12 resulted in depicting suitable significant binding with furin, RNA dependent RNA polymerase (RdRp), Main proteases (Mpro), ORF3a and ORF7a and Vitamin D3 with spike protein and vitamin B9 with non structural protein 3 (NSP3). A detailed examination of vitamins suggests that vitamin B12 may be the component that reduces virulence by blocking furin which is responsible for entry of virus in the host cell. Details from the Molecular Dynamics (MD) simulation study aided in determining vitamin B12 as a possible furin inhibitor.

ABSTRACT

OBJECTIVE: The COVID-19 pandemic prompted health systems to rapidly adopt telehealth for clinical care. We examined the impact of demography, subspecialty characteristics, and broadband availability on the utilization of telehealth in pediatric populations before and after the early period of the COVID-19 pandemic. METHODS: Outpatients scheduled for subspecialty visits at sites affiliated with a single quaternary academic medical center between March-June 2019 and March-June 2020 were included. The contribution of demographic, socioeconomic, and broadband availability to visit completion and telehealth utilization were examined in multivariable regression analyses. RESULTS: Among visits scheduled in 2020 compared to 2019, in-person visits fell from 23,318 to 11,209, while telehealth visits increased from 150 to 7,675. Visits among established patients fell by 15% and new patients by 36% (P < .0001). Multivariable analysis revealed that completed visits were reduced for Hispanic patients and those with reduced broadband; high income, private non-HMO insurance, and those requesting an interpreter were more likely to complete visits. Those with visits scheduled in 2020, established patients, those with reduced broadband, and patients older than 1 year were more likely to complete TH appointments. Cardiology, oncology, and pulmonology patients were less likely to complete scheduled TH appointments. CONCLUSIONS: Following COVID-19 onset, outpatient pediatric subspecialty visits shifted rapidly to telehealth. However, the impact of this shift on social disparities in outpatient utilization was mixed with variation among subspecialties. A growing reliance on telehealth will necessitate insights from other healthcare settings serving populations of diverse social and technological character.

ABSTRACT

Many US states published crisis standards of care (CSC) guidelines for allocating scarce critical care resources during the COVID-19 pandemic. However, the performance of these guidelines in maximizing their population benefit has not been well tested. In 2,272 adults with COVID-19 requiring mechanical ventilation drawn from the Study of the Treatment and Outcomes in Critically Ill Patients with COVID-19 (STOP-COVID) multicenter cohort, we test the following three approaches to CSC algorithms: Sequential Organ Failure Assessment (SOFA) scores grouped into ranges, SOFA score ranges plus comorbidities, and a hypothetical approach using raw SOFA scores not grouped into ranges. We find that area under receiver operating characteristic (AUROC) curves for all three algorithms demonstrate only modest discrimination for 28-day mortality. Adding comorbidity scoring modestly improves algorithm performance over SOFA scores alone. The algorithm incorporating comorbidities has modestly worse predictive performance for Black compared to white patients. CSC algorithms should be empirically examined to refine approaches to the allocation of scarce resources during pandemics and to avoid potential exacerbation of racial inequities.

ABSTRACT

Patients with psychiatric illness feel the brunt of the intersection of many of our society's and our health care system's disparities, and the vulnerability of this population during the Covid-19 pandemic cannot be overstated. Patients with psychiatric illness often suffer from the stigma of mental illness and receive poor medical care. Many patients with severe and persistent mental illness face additional barriers, including poverty, marginal housing, and food insecurity. Patients who require psychiatric hospitalization now face the risk of transmission of Covid-19 due to the inherent difficulties of social distancing within a psychiatric hospital. Patients whose freedom and self-determination have been temporarily overruled as they receive involuntary psychiatric treatment deserve a setting that maintains their health and safety. While tele-mental health has been rapidly expanded to provide new ways to access psychiatric treatment, some patients may have limitations in technological literacy or access to devices. The social isolation, economic fallout, and potential traumatization related to the current pandemic will disproportionately affect this vulnerable population, and society's duties to them must be considered.
