BACKGROUND With the wide use of antibiotics, antibiotic-resistant Helicobacter pylori strains are becoming increasingly prevalent. It has been hypothesized that culture-guided therapy might help to increase treatment success. But the effects and the costs still remain controversial. AIMS To systematically review the efficacy and the cost of culture-guided triple therapy, compared to standard ...

AIM To evaluate the efficacy of antimicrobial susceptibility-guided therapy before first-line treatment for infection in patients with dual or triple antibiotic resistance. METHODS A total of 1034 patients infected by Helicobacter pylori (H. pylori) during 2013-2014 were tested for antimicrobial susceptibility. 157 of 1034 (15%) patients showed resistance to two (127/1034; 12%) and to three (...

Polyol-ester-based carbon black pastes are used to either coat or penetrate flexible graphite, thereby increasing the thermal contact conductance of flexible graphite between copper surfaces. Paste penetration by up to an effective paste thickness (the volume of the penetrated paste divided by the geometric area of the flexible graphite) of 5 lm increases the conductance by up to 350%, 98% and ...

With the rising prevalence of antimicrobial resistance, the treatment success of standard triple therapy has recently declined to unacceptable levels (ie, 80% or less). Following the failure of conventional triple therapy, novel eradication regimens have been developed including sequential therapy, concomitant quadruple therapy, hybrid (dual-concomitant) therapy, bismuth-containing quadruple th...

De Gascun and colleagues report on a case of methicillinsusceptible Staphylococcus aureus (MSSA) sepsis treated successfully with linezolid after initial failure of a triple regimen of apparently appropriate antibiotics. They ascribe the observed efficacy of linezolid to an anti-toxin effect of the antibiotic. Linezolid acts by inhibiting bacterial protein synthesis, and it, therefore, blocks t...

We developed a novel approach for improving the production of antibiotic from Streptomyces coelicolor A3(2) by inducing combined drug-resistant mutations. Mutants with enhanced (1.6- to 3-fold-higher) actinorhodin production were detected at a high frequency (5 to 10%) among isolates resistant to streptomycin (Str(r)), gentamicin (Gen(r)), or rifampin (Rif(r)), which developed spontaneously on ...

We read with interest the recent meta-analysis by Lin et al who evaluated the effectiveness of concomitant regimen for Helicobacter pylori (H. pylori) in Chinese regions. They found that 7-d concomitant regimen is undoubtedly superior to 7-d triple therapy (91.2% vs 77.9%, P < 0.0001). However, it is a common belief that a triple therapy lasting 7 d should be definitively removed from the clini...
