ABSTRACT

BACKGROUND: The coronavirus disease 2019 pandemic affected many aspects of medical practice, particularly surgical fields. The American College of Surgery initially recommended the cancellation of all elective procedures. As a result, virtual consultations (VCs; a form of telemedicine), became widely used in the field of facial plastic and reconstructive surgery. With more facial plastic and reconstructive surgeons (FPRS) conducting both in-person and virtual visits, it is imperative to understand how VCs are utilized in practice. METHODS: An electronic, anonymous survey was distributed to 1,282 electronic mail addresses in the 2018 American Academy of Facial Plastic and Reconstructive Surgery directory. The survey collected responses on various topics including demographic information and past, current, and future use of VCs. RESULTS: The survey yielded 84 responses. Most surgeons (66.7%) were 11+ years out of fellowship. There was a significant increase in the percentage of VCs scheduled after the pandemic than before (p = 0.03). FPRS most frequently responded that VCs should always be followed by an in-person visit (48.6%). A majority of FPRS (66.2%) believe that VCs have improved the delivery of health care in at least some cases. Almost all FPRS (86.5%) plan on using VCs after the pandemic. CONCLUSION: Since the pandemic, VCs are more frequently used by surgeons and are mostly utilized as an initial patient visit. A majority of FPRS believe that VCs have improved health care in at least some cases, and plan on using VCs after the pandemic.

ABSTRACT

The near real-time detection of airborne particles-of-interest is needed for avoiding current/future threats. The incorporation of imprinted particles into a micelle-based electrochemical cell produced a signal when brought into contact with particle analytes (such as SARS-COV-2), previously imprinted onto the structure. Nanoamp scales of signals were generated from what may've been individual virus-micelle interactions. The system showed selectivity when tested against similar size and morphology particles. The technology was compatible with airborne aerosol sampling techniques. Overall, the application of imprinted micelle technology could provide near real-time detection methods to a host of possible analytes of interest in the field.

ABSTRACT

Multiple coronaviruses have emerged independently in the past 20 years that cause lethal human diseases. Although vaccine development targeting these viruses has been accelerated substantially, there remain patients requiring treatment who cannot be vaccinated or who experience breakthrough infections. Understanding the common host factors necessary for the life cycles of coronaviruses may reveal conserved therapeutic targets. Here, we used the known substrate specificities of mammalian protein kinases to deconvolute the sequence of phosphorylation events mediated by three host protein kinase families (SRPK, GSK-3, and CK1) that coordinately phosphorylate a cluster of serine and threonine residues in the viral N protein, which is required for viral replication. We also showed that loss or inhibition of SRPK1/2, which we propose initiates the N protein phosphorylation cascade, compromised the viral replication cycle. Because these phosphorylation sites are highly conserved across coronaviruses, inhibitors of these protein kinases not only may have therapeutic potential against COVID-19 but also may be broadly useful against coronavirus-mediated diseases.

ABSTRACT

Coagulopathy is a significant aspect of morbidity in COVID-19 patients. The clotting cascade is propagated by a series of proteases, including factor Xa and thrombin. While certain host proteases, including TMPRSS2 and furin, are known to be important for cleavage activation of SARS-CoV-2 spike to promote viral entry in the respiratory tract, other proteases may also contribute. Using biochemical and cell-based assays, we demonstrate that factor Xa and thrombin can also directly cleave SARS-CoV-2 spike, enhancing infection at the stage of viral entry. Coagulation factors increased SARS-CoV-2 infection in human lung organoids. A drug-repurposing screen identified a subset of protease inhibitors that promiscuously inhibited spike cleavage by both transmembrane serine proteases and coagulation factors. The mechanism of the protease inhibitors nafamostat and camostat may extend beyond inhibition of TMPRSS2 to coagulation-induced spike cleavage. Anticoagulation is critical in the management of COVID-19, and early intervention could provide collateral benefit by suppressing SARS-CoV-2 viral entry. We propose a model of positive feedback whereby infection-induced hypercoagulation exacerbates SARS-CoV-2 infectivity.

ABSTRACT

INTRODUCTION: This article reports on the effects of an early outbreak during the COVID-19 pandemic on visit volume and telehealth use by various specialists at a comprehensive cancer center. MATERIALS AND METHODS: The number of on-site and telehealth visits (THV) for medical and surgical specialties were obtained from scheduling software. RESULTS: Total visits were most drastically limited in April 2020 to a low point of 3139; THV made up 28% of all visits. For head and neck surgery, THV made up 54% and 30% of visits in April and May, respectively. Other specialties, such as psychiatry and palliative care, had higher levels of THV. For most specialties, the rebound in June through September did not make up for visits lost during the outbreak, and fiscal year  (FY) 2020 had a 9% loss from FY 2019 with 5786 fewer total annual visits across all specialties. CONCLUSIONS: While telemedicine was a helpful part of this cancer center's response to the initial COVID-19 surge, it was not able to replace the in-person services offered at the same center. The main strategy of physicians at this cancer center was to defer care, with telemedicine being an auxiliary response.

ABSTRACT

There is an urgent need to create novel models using human disease-relevant cells to study severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) biology and to facilitate drug screening. Here, as SARS-CoV-2 primarily infects the respiratory tract, we developed a lung organoid model using human pluripotent stem cells (hPSC-LOs). The hPSC-LOs (particularly alveolar type-II-like cells) are permissive to SARS-CoV-2 infection, and showed robust induction of chemokines following SARS-CoV-2 infection, similar to what is seen in patients with COVID-19. Nearly 25% of these patients also have gastrointestinal manifestations, which are associated with worse COVID-19 outcomes1. We therefore also generated complementary hPSC-derived colonic organoids (hPSC-COs) to explore the response of colonic cells to SARS-CoV-2 infection. We found that multiple colonic cell types, especially enterocytes, express ACE2 and are permissive to SARS-CoV-2 infection. Using hPSC-LOs, we performed a high-throughput screen of drugs approved by the FDA (US Food and Drug Administration) and identified entry inhibitors of SARS-CoV-2, including imatinib, mycophenolic acid and quinacrine dihydrochloride. Treatment at physiologically relevant levels of these drugs significantly inhibited SARS-CoV-2 infection of both hPSC-LOs and hPSC-COs. Together, these data demonstrate that hPSC-LOs and hPSC-COs infected by SARS-CoV-2 can serve as disease models to study SARS-CoV-2 infection and provide a valuable resource for drug screening to identify candidate COVID-19 therapeutics.

ABSTRACT

Introduction The COVID-19 pandemic has led to a reduction in surgical and clinical volume, which has altered the traditional training experience of the otolaryngology resident. Objective To describe the strategies we utilized to maximize resident education as well as ensure patient and staff safety during the pandemic. Methods We developed a system that emphasized three key elements. First and foremost, patient care remained the core priority. Next, clinical duties were restructured to avoid unnecessary exposure of residents. The third component was ensuring continuation of resident education and maximizing learning experiences. Results To implement these key elements, our residency divided up our five hospitals into three functional groups based on geographical location and clinical volume. Each team works for three days at their assigned location before being replaced by the next three-person team at our two busiest sites. Resident teams are kept completely separate from each other, so that they do not interact with those working at other sites. Conclusions Despite the daily challenges encountered as we navigate through the COVID-19 pandemic, our otolaryngology residency program has been able to establish a suitable balance between maintenance of resident safety and well-being without compromise to patient care.

ABSTRACT

OBJECTIVES: To gain a better understanding of the effects the COVID-19 pandemic has had on current and future pediatric otolaryngology fellowship training, as well as how the application process was impacted this past year. METHODS: An anonymous web-based survey consisting of 24 questions was sent to all fellowship directors. The survey questions were designed to gain a better understanding of the effects of the current COVID-19 pandemic on the surgical and clinical experience of current, to characterize the types of supplemental educational experiences that fellowship directors had incorporated into the curriculum to compensate for the decreased surgical and clinical workload, and highlight differences based on geographic location. RESULTS: Overall, 22 of 36 fellowship directors responded to our survey, for a total response rate of 61%. The Midwest had the highest response rate at 72.7%, followed by the Northeast (71.4%), the West (50%), and the South (50%). The vast majority of fellowship directors (77.2%) reported the COVID-19 pandemic had a "significant impact" on overall pediatric otolaryngology fellowship training. 86.3% of fellowship directors reported that their programs were still performing some surgical operations, but with decreased overall volume. Interestingly, 13.6% of fellowship directors reported that their fellows had been pulled to medicine or ICU services to assist with the COVID-19 pandemic. Of these programs that had a fellow pulled to the ICU or medicine service, 2 out of 3 were located in the Northeast, with the remaining fellow being from a program in the South. CONCLUSION: Overall, pediatric otolaryngology fellowship directors reported the COVID-19 pandemic has had a significant impact on the overall fellowship experience within the field of pediatric otolaryngology, with the majority feeling that both their fellows surgical and clinical experience have been significantly impacted.
