Epidemiology of Clostridium difficile infection in Portugal: Experience at a tertiary care hospital.

CONCLUSIONS: CDI incidence achieved a peak in 2009/2010 coinciding with the introduction of alcohol-based hand products, increase in quinolone and carbapenem prescription and a possible outbreak of an epidemic strain. Female gender, LTCF residency and exposure to three or more antibiotics are risk factors for refractory and recurrent CDI. We emphasize the need to restrict use of large spectrum antibiotics.

GudasAbstractEthanol (EtOH) is a recreationally ingested compound that is both teratogenic and carcinogenic in humans. Because of its abundant consumption worldwide and the vital role of stem cells in the formation of birth defects and cancers, delineating the effects of EtOH on stem cell function is currently an active and urgent pursuit of scientific investigation to explicate some of the mechanisms contributing to EtOH toxicity. Stem cells represent a primordial, undifferentiated phase of devel...

Gibril, Fangong KongAbstractApplication of the lignin-based monomer in polymers synthesis will reducing the use of petrochemical-based monomers, enhance the polymer/copolymers properties, and disposing lignin in a profitable way. Accordingly, in this work, the lignin-vinyl acetate monomer (LVAc) and its copolymers were synthesized successfully. To obtain the LVAc, firstly, lignin was activated with the amine using diethylenetriamine (DETA) and then followed by the grafting with chlorovinyl aceta...

In this study, we introduce a novel approach with high digestion efficiency that involves using Fenton’s reagent and nitric acid to remove feces solids. Firstly, Fenton’s reagent was used to degrade small solids and decompose large solids into small pieces. Secondly, nitric acid was used to digest the remaining solids and filters. Furthermore, absolute ethyl alcohol was used to remove the mineral residues wrapped on the plastic surfaces and disperse MPs. By using this method, 97.78 % MPs can be recovered from human and chicken feces, and no significant changes were observed in the physical and Raman spectral pr...

ConclusionsAdjunctive procedures that can facilitate a decrease in the cumulative dosages of corticosteroids and immunosuppressants have great value in the management of PV. CO2 laser vaporization is a safe procedure with minimal morbidity and no long-term side effects and should be considered as an adjunctive treatment option for management of recalcitrant lesions in patients with oral PV.
