The impact of SARS-COV2 pandemic on the management oF IPF patients: Our narrative experience
2021
Abstract Background The SARS-CoV-2 pandemic has changed the health-care systems around the world in a remarkable way. We describe the strategies adopted to cope with the limitations imposed by the pandemic to the access to health care by patients diagnosed with idiopathic Pulmonary Fibrosis (IPF). Material and methods We conducted a retrospective observational analysis including IPF patients under antifibrotic drugs (nintedanib and pirfenidone) that accessed to the Outpatient clinic of the University of Palermo, Italy. Patients received a phone number and an email address in case of any urgency and a virtual meeting was settled up monthly. Results 40 patients (M/F: 30/10) were followed up, …
Severe asthma and COVID-19: lessons from the first wave
2020
Objective: Severe asthma is considered a risk factor for SARS-Coronavirus 2 (SARS-CoV-2) infection but scientific evidences are lacking. Methods: we performed a literature search and review based on PubMed database national, international recommendations as well as papers on severe asthmatic patients and their management during SARS-CoV-2 pandemic. Results: the majority of international recommendations, expert panels and editorials provide indications about management of severe asthmatic patients. No published studies evaluated the effects of biologic agents on severe asthmatic patients during SARS-CoV-2 pandemic. Conclusions: the relationship between SARS-CoV-2 and asthma is variable world…
Binding and Reactivity of a Nitrile Oral Inhibitor of SARS-CoV-2 Main Protease Revealed by Computational Simulations
2021
We present a detailed analysis of the binding mode and reactivity of the novel oral inhibitor PF-07321332 developed against SARS-CoV-2 3CL protease. Classical and QM/MM Molecular Dynamics simulations are used to quantify the contributions to the binding free energy and the reaction mechanism for covalent inhibition. The small size of the nitrile warhead conferes additional advantadges to this inhibitor.
In silico molecular investigations of pyridine N-Oxide compounds as potential inhibitors of SARS-CoV-2: 3D QSAR, molecular docking modeling, and ADME…
2020
The new coronavirus SARS-CoV-2 virus is causing a severe pneumonia in human, provoking the serious outbreak epidemic CoV-2. Since its appearance in Wuhan, China on December 2019, CoV-2 becomes the biggest challenge the world is facing today, including the discovery of antiviral drug for SARS-CoV-2. In this study, the potential inhibitory of a class of human SARS inhibitors, namely pyridine N-oxide derivatives, against CoV-2 was addressed by quantitative structure-activity relationship 3 D-QSAR. The reliable CoMSIA developed model of 110 pyridine N-oxide based-antiviral compounds, showed Q

Pooling of Nasopharyngeal Swab Specimens for SARS-CoV-2 detection by RT-PCR
2020
ABSTRACTSystematic testing of large population groups by RT-PCR is mandatory to Covid-19 case identification and contact tracing in order to minimize the likelyhood of resurgence in contagion. Sample pooling for RT-PCR has been effectively used to detect community transmission of SARS CoV-2. Nevertheless, this procedure may decrease the sensitivity of RT-PCR assays due to specimen dilution. We evaluated the efficacy of this strategy for diagnosis of Covid-19 using a sensitive commercially-available RT-PCR targeting SARS CoV-2 E and RdRp genes in a single reaction. A total of 20 mini-pools containing either 5 (n=10) or 10 (n=10) nasopharyngeal exudates collected in universal transport medium…
Socio-Demographic Factors Involved in a Low-Incidence Phase of SARS-CoV-2 Spread in Sicily, Italy
2021
Background: The present study analysed SARS-CoV-2 cases observed in Sicily and investigated social determinants that could have an impact on the virus spread. Methods: SARS-CoV-2 cases observed among Sicilian residents between the 1 February 2020 and 15 October 2020 have been included in the analyses. Age, sex, date of infection detection, residency, clinical outcomes, and exposure route have been evaluated. Each case has been linked to the census section of residency and its socio-demographic data. Results: A total of 10,114 patients (202.3 cases per 100,000 residents
Management of patients with atopic dermatitis undergoing systemic therapy during COVID-19 pandemic in Italy: Data from the DA-COVID-19 registry
2021
Abstract Background Few and small studies have described the management of immunomodulant/immunosuppressive therapies or phototherapy in atopic dermatitis (AD) patients during coronavirus disease 2019 (COVID‐19) pandemic. Methods A national registry, named DA‐COVID‐19 and involving 35 Italian dermatology units, was established in order to evaluate the impact of COVID‐19 pandemic on the management of adult AD patients treated with systemic immunomodulant/immunosuppressive medications or phototherapy. Demographic and clinical data were obtained at different timepoints by teledermatology during COVID‐19 pandemic, when regular visits were not allowed due to sanitary restrictions. Disease severi…
Risk perception of sars-cov-2 infection and implementation of various protective measures by dentists across various countries
2021
Objective: Healthcare workers in general are at a high risk of potential infections with COVID-19, especially those who work with aerosol generating procedures. Dentists fall in this category, as not only do they operate with aerosol generating procedures but also operate within a face-to-face contact area. Methods: A structured self-administered questionnaire was developed at Najran University and provided to the participants for data collection. The data collected included information on risk perception and incorporation of measures for protection against COVID-19 to gauge the attitude of dentists during this period. Also, clinical implementation of various protective measures was reviewe…
