Can a Breakthrough Medical Device Reduce the Risk of Hospital-Associated  Infections?

The Centers for Disease Control and Prevention (CDC) has recently identified medical devices used in the ICU as a major source of antibiotic-resistant infections. N8 Medical’s CeraShield technology may help reduce such infections by preventing fouling and formation of bacterial and fungal biofilms on device surfaces. FDA has designated the company’s CeraShield Endotracheal Tube (ETT) as a “breakthrough” device, pursuant to the 21st Century Cures Act based on its potential life-saving properties. And N8 reported that Frost &Sullivan had selected it as the winner of a North American New Product Innovation Award. The first in-human studies in mechanically ventilated ICU patients show that the device is able to prevent ESKAPE pathogens in endotracheal tube aspirates and on the device itself. In vitro data show that the device is also able to prevent colonization by Candida auris, which CDC has recently elevated to “urgent” concern. The technology is broadly applicable to any indwelling medical device across multiple medical specialties. Indwelling medical devices, such as the endotracheal tubes used in mechanical ventilators, are abiotic, meaning that they are very good breeding grounds for bacteria and fungi, said Carl Genberg, N8 Medical's Chief Scientific Officer. “I...

In conclusion, gut Candida induced bacteremia in the DSS model through an inflammation-induced gut perm-selectivity defect and facilitated the growth of some gut bacteria. Treatment strategies aimed at reducing gut fungi could attenuate disease severity. Further investigation of gut fungi in inflammatory bowel disease is warranted.

ecka Milewski The development and spread of resistance of human pathogenic bacteria to the action of commonly used antibacterial drugs is one of the key problems in modern medicine. One of the especially dangerous and easily developing antibiotic resistant bacterial species is Staphylococcus aureus. Anthra[1,2-d][1,2,3]triazine-4,7,12(3H)-triones 22–38 have been developed as novel effective antistaphylococcal agents. These compounds have been obtained by sequential conversion of 1-amino-9,10-dioxo-9,10-dihydroanthracene-2-carboxylic acid (1) and 1-amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-carboxyli...

Abstract Candida is one of the most prevalent fungal pathogens in clinical settings which form antibiotic-resistant biofilms on biomedical devices. Hence, there is a need for non-antimicrobial alternatives to combat these infections. The present study investigates the anti-biofilm effect of marine bacterial DNase by targeting the eDNA present in the biofilms of Candida spp. A strain of Vibrio alginolyticus (AMSII) which showed enhanced DNase activity was isolated from marine sediment. Treatment of young and mature Candida biofilms with purified marine bacterial DNase (MBD) caused a 60-80% reduction in biofilm biom...

Objective: to study features of pulmonary complications in intravenous drug users (IDUs) with and without HIV.Materials and Methods: 149 patients (111 were males, mean age - 34,6±5,2 years)- IDUs diagnosed with pneumonia who were included in the study as they admitted to the hospital. HIV infection was verified in 112 (75%). 105 (70%) patients had viral hepatitis (B, C, B+C), 70 (47%) -tuberculosis.Results: In the presence of HIV infection, especially with severe immunosuppression of CD4+

(CNN) — Every 15 minutes, someone in the United States dies of a superbug that has learned to outsmart even our most sophisticated antibiotics, according to a new report from the US Centers for Disease Control and Prevention. That’s about 35,000 deaths each year from drug-resistant infections, according to the landmark report. The report places five drug-resistant superbugs on the CDC’s “urgent threat” list — two more germs than were on the CDC’s list in 2013, the last time the agency issued a report on antibiotic resistance. Genetic research shows germs have become especially adep...

In this study, a green synthesis approach was used to create a composite hydrogel (CoHy) of RSF stabilized with CarboxymethylCellulose-Na (CMC-Na) and loaded with AgNPs. Their swelling ratios were up to 59 g/g when tested in different physiologically relevant fluids. Material characterizations by Scanning electron microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS), and X-Ray Diffraction (XRD) confirmed the presence of AgNPs on the surface. Antimicrobial properties of the CoHy samples were evaluated using agar diffusion tests. The results showed distinct inhibition zones against major microorganisms found in...

In this study, two small peptides, RcAlb-PepI and RcAlb-PepII, were designed based on the primary structure of Rc-2S-Alb, a 2S albumin from the seed cake of Ricinus communis, and their antimicrobial activity assessed. RcAlb-PepII strongly inhibited the growth of Klebsiella pneumoniae and Candida parapsilosis, and induced morphological alterations in their cell surface. C. parapsilosis exposed to RcAlb-PepII presented higher cell membrane permeabilization and elevated content of reactive oxygen species. RcAlb-PepII also degraded and reduced the biofilm formation in C. parapsilosis and in K. pneumonia cells. Experimentally, ...

ConclusionsExtracts from AOK had interesting anti-inflammatory activity in mice, alleviating effect against OVA-induced AR in guinea pigs, and antimicrobial activities in vitro, which support the ethno-medicinal use of it. The main constituents in ethyl acetate layer of AOK root extract are dicaffeoylquinic acids and could bind with histamine-1 receptor well. These findings highlighted the importance of natural product chemistry study of AOK.Graphical abstract
