Assessing the airborne survival of bacteria in aerosol droplets from coughs and sneezes

The airborne transmission of diseases including the common cold, influenza and tuberculosis is something that affects everyone with an average sneeze or cough sending around 100,000 contagious germs into the air at speeds of up to 100 miles per hour.

Publication date: 15 June 2019Source: Journal of Molecular Structure, Volume 1186Author(s): Vinodkumar, Jathi KeshavayyaAbstractThree novel bioactive azo dyes were synthesized by a classical diazo-coupling method using sulfamethazine with three different N, N-dimethyl aniline derivatives as coupling components under appropriate experimental conditions. The structural features of the newly synthesized compounds were explored by using various analytical and spectroscopic techniques. Further, these compounds were assessed for the different pharmacological activities such as antimicrobial, anti-tuberculosis, antioxidant and an...

This study reported results obtained from electrochemical impedance spectroscopy (EIS), polarization measurement, and weight loss, scanning electron microscopy equipped with energy dispersive x-ray analysis (SEM-EDX), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The experimental results were excellently complemented with the results obtained from density functional theory, i.e. DFT and molecular dynamics, i.e. MD. These hydrazones inhibited corrosion by adsorbing themselves on the metal surface which was confirmed by SEM-EDX and XPS results. All the synthesized inhibitors showed appreciable eff...

This study aimed to evaluate ichroma™ IGRA-TB, a novel point-of-care platform for assaying IFN-γ release, and to compare it with QuantiFERON-TB Gold In-Tube (QFT-GIT) for identifying Mycobacterium tuberculosis (M. tb) infection. MATERIALS AND METHODS: We recruited 60 healthy subjects, and blood samples were obtained in QFT-GIT blood collection tubes. The blood collection tubes were incubated at 37°C, and culture supernatant was harvested after 18-24 hours. IFN-γ responses were assessed by the ichroma™ IGRA-TB cartridge and the QFT-GIT IFN-γ enzyme-linked immunosorbent assay. Three act...

Even the microbiome at distal sites has an important function in respiratory health. However, the clinical importance of the microbiome in tuberculosis, the biggest infectious cause of death worldwide, is only starting to be understood. Here, we critically review research on the microbiome's associatio...

We describe a 45-year-old man with ARDS and progressive lung fibrosis secondary to H1N1 pneumonia who was treated for 45 days with venovenous extracorporeal membrane oxygenation as a rescue utility and bridge to bilateral lung transplantation. The patient was saved and lived well. Lung transplantation may be a viable alternative for patients with lung fibrosis secondary to H1N1-induced ARDS in very selected situations.

However, the long-term outcome of airway metallic stenting in RP patients remained unclear.MethodsWe retrospectively analyzed patients with relapsing polychondritis who underwent airway metallic stenting with the use of fiberoptic bronchoscopy ...

Authors: Hughes LM, Clarke J Abstract Pressurized Submarine Escape Training (PSET) physically prepares submariners to safely escape a submarine at depth. Failure to complete PSET is not a submarine service disqualification. Serious medical incidents are rare, but the safety record tradeoff has been low throughput. From 2009 to 2015, only 34% of students screened completed PSET. Students may be medically screened out of the training altogether (disqualified), or dropout during the physical training (attrite). Training records from 12,122 U.S. Navy students were used to identify factors contributing to training disqu...

Using national mortality register data through 1998-2015 in Mexico, influenza-associated mortality was estimated for respiratory, cardiovascular, and all-cause events. The proportion of influenza-associated respiratory and cardiovascular deaths among different age groups were compared. There were 8,853,986 death ...
