Battelle Earns FDA EUA for Decontaminating Respirator Masks

FDA has granted Emergency Use Authorization (EUA) to Battelle's CCDS Critical Care Decontamination System for processing up to 80,000 respirator masks per system each day. CCDS employs concentrated, vapor-phase hydrogen peroxide (VPHP) for decontamination. The system has been validated to decontaminate masks of SARS-CoV-2, the company reported. The masks are placed on shelves inside a container, and a portable, external VPHP system is hooked up to the outside of container. The system was first envisioned by Battelle as part of a study commissioned by FDA in 2015. That study involved determining the feasibility of N95 respirator mask decontamination in the event of a personal protective equipment (PPE) shortage in a pandemic. The FDA study showed that VPHP decontamination using the same system parameters and critical end points as the current system resulted in 6-log reduction of G. stearothermophilus while not degrading the filter performance of N95 respirators for multiple decontamination cycles, Battelle reported in a news release. "We have proven that VPHP is effective at decontaminating N95 respirator masks up to 20 times at large scale," said Matt Vaughan, president of contract research at Battelle. The masks are exposed to the validated concentration level for 2.5 hours to decontaminate biological contaminates, including SARS-CoV-2, the company reported. Battelle is currently examining whether other supplies such as surgical masks and ventilator components can...

Conclusions: Early results of universal preoperative screening for COVID-19 demonstrates a low incidence and high rate of asymptomatic patients. Health care professionals, especially those at higher risk for the virus, should be aware of the challenges related to screening based solely on symptoms or travel history and consider universal screening for patients undergoing elective surgery. Level of Evidence: Level II.

This study has been performed by molecular docking of the compounds using PyRx with AutoDock Vina on the two aforementioned targets chosen for this study, i.e., SARS-CoV-2 Mpro and TMPRSS2. The compounds showed good binding affinity and are further analyzed by (Molecular dynamic) MD and Molecular Mechanics Poisson-Boltzmann Surface Area MM-PBSA study. The MD-simulation study has predicted that these natural compounds will have a great impact on the stabilization of the binding cavity of the Mpro of SARS-CoV-2. The predicted pharmacokinetic parameters also show that these compounds are expected to have good solubility and a...

After being epidemic in China, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) infection has rapidly spread in many countries as a global pandemic, with the number of affected cases dramatically increasing worldwide on a daily basis. Although the median age of hospitalized patients with confirmed infection is usually more advanced 1, with older age reported to be associated to higher mortality rate 2, physiological adaptations occurring during pregnancy have been claimed to be potentially responsible for a more severe respiratory disease, thus leading to higher rates of maternal and fetal complications 3,4.

Steve Lindsay, a public health entomologist at Durham University, is midway through explaining how dogs might play a role in detecting COVID-19 infections when a decidedly less-well trained canine interrupts our conversation. “If you’ll excuse me for a minute, I’ve got a naughty black Labrador out in the back garden doing something it shouldn’t be doing,” Lindsay says. He disappears. I hear barking. He returns accompanied by a chocolate lab. “She’s not as skilled as the detection dogs,” Lindsay says as the pup tries to lick his face. “But it’s really interesting t...

Authors: Batista RCS, Arruda CVB, Cassimiro M, Gominho L, Moura AC, Albuquerque DS, Romeiro K Abstract As early as December 2019 in the province of Hubei, China, contamination of patients with pneumonia of an unknown etiology occurred. These patients presented with symptoms such as coughing, sore throat, malaise, diarrhea, high fever, and dyspnea. This emerging disease was named COVID-19 due to being part of the group of coronaviruses (CoVs) belonging to the subfamily Orthocoronavirinae, in the Coronaviridae family and in the Nidovirales order. COVID-19 is most commonly transmitted through speech, coughing, sneezin...

Since the appearance of the novel coronavirus (severe acute respiratory syndrome-coronavirus-2) and related coronavirus disease 2019 (COVID-19) in China in December 2019, a very high number of small and large patient series have been published in literature from around the world. Even though the classical presentation of COVID-19 is one with respiratory symptoms with or without pneumonia that can be self-limiting or evolve into severe respiratory distress syndrome with multiple organ failure, and secondary bacterial sepsis, a large body of evidence suggests a plethora of other types of clinical presentation. In this exhaus...
