INTRODUCTION Selective decontamination of the digestive tract (SDD) is a prophylactic antibiotic regimen that is not widely used in practice. We aimed to describe the opinions of key 'stakeholders' about the validity of the existing evidence base, likely consequences of implementation, relative importance of their opinions in influencing overall practice, likely barriers to implementation and p...
This paper presents algorithms and data structures that exploit a compositional and hierarchical specification to enable more efficient symbolic modelchecking. We encode the state space and transition relation using hierarchical Set Decision Diagrams (SDD) [9]. In SDD, arcs of the structure are labeled with sets, themselves stored as SDD. To exploit the hierarchy of SDD, a structured model repr...
The effect of a selective decontamination of the digestive tract (SDD) regimen including polymyxin and tobramycin on several body site reservoirs was compared between a test group and a control group in intensive care unit (ICU) patients with faecal multi-resistant Acinetobacter baumannii colonization. SDD significantly reduced faecal and pharyngeal carriage when compared with the control group...
TO THE EDITOR—The recent systematic review of 157 studies of pneumonia prevention methods in the intensive care unit (ICU) by Roquilly et al is of great interest [1]. Two of their findings—the importance of systemic antimicrobial therapy in selective decontamination of the digestive tract (SDD) and the apparent benefit among 29 randomized studies of SDD with 6089 patients vs its insignificance ...
We report a two dimensional DNA lattice (named 2D staggered doubledecker lattice, abbreviated to 2D-SDD lattice) and a three dimensional DNA lattice (named 3D staggered doubledecker lattice, abbreviated to 3D-SDD lattice) self-assembled from the doubledecker tile. The doubledecker (DD) tile is a cross shaped DNA nanostructure that has previously been shown (Majumder et al., 2011) to assemble in...
We consider blind equalisation for high-order quadrature amplitude modulation channels using a lowcomplexity high-performance concurrent constant modulus algorithm (CMA) and soft decision-directed (SDD) scheme. Instead of using a constant step size, we design a fuzzy-logic (FL) tuning unit to adjust the step size of the CMA. Simulation investigation confirms that faster convergence can be achie...
BACKGROUND Selective digestive tract decontamination (SDD) and selective oropharyngeal decontamination (SOD) are infection-prevention measures used in the treatment of some patients in intensive care, but reported effects on patient outcome are conflicting. METHODS We evaluated the effectiveness of SDD and SOD in a crossover study using cluster randomization in 13 intensive care units (ICUs),...
S-SDD class of matrices has been introduced in [1] as a generalization of Ostrowski class, known in the literature also as doubly diagonally dominant matrices. As it was shown in [2], this class can be characterized by the special form of its “scaling” into an SDD matrix. Due to this fact, we can use S-SDD matrices as a tool for measuring and exploiting the magnitude of diagonal dominance. How ...
We read with interest the review entitled ‘‘Evidence on measures for the prevention of ventilator-associated pneumonia’’ by LORENTE et al. [1]. We enjoyed the paper as it is comprehensive and based on an appropriate design. In particular, we welcome the authors’ acknowledgement of the proven clinical benefits of selective decontamination of the digestive tract (SDD). The authors give four expla...
AIM This multi-centre, prospective, controlled trial was designed to examine the biological response of the matrix metalloproteinase(MMP) inhibitor subantimicrobial dose doxycycline (SDD) combined with access flap surgery on periodontal wound repair in patients with chronic severe periodontitis. MATERIAL AND METHODS Seventy subjects were enrolled into a 12-month, randomized, placebo-controlle...
