An important secondary finding was that patients with a Thiazovivin clinical trial cuff pressure

of <= 225 mm Hg had no postoperative infections and a lower rate of wound complications.”
“Many bacteria grow on surfaces forming biofilms but often high dosages of antibiotics can not clear infectious biofilms. Biofilms are controlled by a process called quorum-sensing triggered by species-specific, small, diffusible autoinducers (N-acyl homoserine lactones (AHL), small peptides or a furanosyl borate diester). Several herbal, animal and microbial extracts possess quorum-quenching activity but only few active compounds and synthetic analogues are known. However, quorum-sensing seems not to be the only way to control biofilms. Bacteria have mechanisms to dissolve their biofilms and return to planktonic lifestyle. Only few compounds responsible for the signalling of these processes are known but may open a completely novel line of biofilm control. Furthermore, controlling the attachment of bacterial by inhibiting the formation of pili is another option and some inhibitors have already been characterized. In this

article different approaches see more to control bacterial biofilms are discussed together with the balance between biofilm formation and virulence.”
“Aims: To describe the prevalence of recent use of alcohol, medication, and illegal drugs among patients who attended emergency departments (EDs) as a result of suffering an injury due to any external mechanism and to identify factors associated with alcohol and drug use.

Methods: A cross-sectional study was conducted in eight university hospitals in Spain. Participants were adult patients admitted to a trauma ED. Oral fluid was used to test for psychoactive substances analyzed by gas

chromatography-mass spectrometry. Socio-demographic data and information on circumstances of the injury were collected through interviews.

Results: The analysis included 1579 patients admitted to the EDs (56.4% men). Among Young people (<40 years), 21.4% of men and 8.5% of women were positive for any illegal substance, primarily cannabinoids or cocaine; 24.7% of men and 14.8% of women were positive for alcohol. Among patients >= 40 years, 7.4% of men and 1.6% of women were positive click here for any illegal substance, and 16.3% and 11.0% respectively for alcohol. Prevalence of substance detected varied across mechanism of injury, gender and age group. Night-time injury was associated with substance use.

Conclusions: A high proportion of injured patients who were treated in an EDs tested positive for psychoactive drugs. Routine testing at trauma departments would maximize the identification of patients who may benefit from referral to specialized addiction treatment centers, or brief interventions.
