Quantitative Proteomic Analysis of the Expression of SARS-CoV-2 Receptors in the Gut of Patients with Chronic Enterocolitis.
The cellular entry of severe respiratory syndrome coronavirus-2 (SARS-CoV-2) is mediated by interaction with the human angiotensin-converting enzyme 2 (ACE2), a receptor that is expressed on both lung and intestinal epithelial cells. We performed a quantitative proteomic analysis to investigate the expression of possible receptors for SARS-CoV-2 in the intestinal mucosa of 23 patients with chronic colitis. ⋯ Additionally, the expression levels of some probable co-receptors, including dipeptidyl peptidase 4 (DPP4), aminopeptidase N (AMPN), and glutamyl aminopeptidase (AMPE), were unchanged in the affected UC, CD, intestinal BD, and intestinal TB colon mucosa samples. In conclusion, gut inflammation associated with chronic colitis does not mediate a further increase in the cellular entry of SARS-CoV-2.

The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected more than 6 million people globally; and changed the dynamics of the entire world. In March 2020, novel coronavirus disease 2019 (COVID-19) was declared as a pandemic by the World Health Organization (WHO). In Pakistan, the first case of COVID-19 was reported on 26th February, 2020. ⋯ In the scenario of a lockdown, dental students are suffering a lot and the dental colleges and faculties must try their best to overcome this situation. This article aims to review the challenges faced by dental community to carryout teaching and training in dental education during the COVID-19 pandemic. Key Words: COVID-19, Dentistry, Education, Pakistan, Pandemic.

Psychological effects of the COVID 19 pandemic on healthcare workers globally: A systematic review.
In this systematic review, we compared the incidences of psychological issues during the COVID-19 pandemic, such as anxiety, depression, occupational stress, PTSD and insomnia, in healthcare workers (HCW) and non-healthcare workers (NHCW). PubMed, Ovid, Google Scholar and PsycInfo were systematically searched for related published articles. In all electronic databases, the following search strategy was implemented, and these key words were used: "COVID 19″ OR "SARS-CoV-2″ AND "psychological" OR "stress" OR "depression" AND "healthcare$". ⋯ Summary effects of individual manifestations indicated significantly higher incidence of insomnia among HCW, when compared to NHCW. Qualitative evidence from remaining cross-sectional studies provided additional information into the nature of the psychological issues. We conclude that even though reasons for psychological distress among HCW and NHCW may be different, both suffered in equal measures excepting for insomnia.

The Early Effects of Coronavirus Disease-2019 on Head and Neck Oncology and Microvascular Reconstruction Practice: A National Survey of Oral and Maxillofacial Surgeons Enrolled in the Head and Neck Special Interest Group.
The coronavirus disease-2019 (COVID-19) pandemic has affected healthcare systems across the nation. The purpose of this study is to gauge the early effects of the COVID-19 pandemic on head and neck oncology and reconstructive surgery (HNORS) practice and evaluate their practice patterns especially ones that might be impacted by COVID-19 and compare them to the current literature. ⋯ The COVID-19 pandemic had a small impact on the surgical treatment of patients with head and neck oncology. Most HNORS surgeons are practicing in accordance with recently published literature.

There is an urgent need for safe and effective approaches to combat COVID-19. Here, we asked whether lessons learned from nanotoxicology and nanomedicine could shed light on the current pandemic. SARS-CoV-2, the causative agent, may trigger a mild, self-limiting disease with respiratory symptoms, but patients may also succumb to a life-threatening systemic disease. ⋯ Moreover, recent work has shown that synthetic nanoparticles wrapped with host-derived cellular membranes may prevent virus infection. We posit that nanoparticles decorated with ACE2, the receptor for SARS-CoV-2, could be exploited as decoys to intercept the virus before it infects cells in the respiratory tract. However, close attention should be paid to biocompatibility before such nano-decoys are deployed in the clinic.
