2010年5月27日 · Gram-negative bacteremia has been associated with severe sepsis, although the exact mechanism and pathophysiological differences among bacterial species are not well understood. In the previous issue of Critical Care, Abe and colleagues report results of a retrospective study that show a significantly higher incidence of Gram-negative bacteremia …

2023年11月30日 · Background Bacteria are the main pathogens that cause sepsis. The pathogenic mechanisms of sepsis caused by gram-negative and gram-positive bacteria are completely different, and their prognostic differences in sepsis remain unclear. Methods The PubMed, Web of Science, Cochrane Library, and Embase databases were searched for …

2002年5月9日 · This review describes the microbiology, diagnosis and management of bacteremia caused by anaerobic bacteria in children. Bacteroides fragilis, Peptostreptococcus sp., Clostridium sp., and Fusobacterium sp. were the most common clinically significant anaerobic isolates. The strains of anaerobic organisms found depended, to a large extent, on the portal …

2018年11月16日 · In general, reasonable coverage is required for common Gram-positive and Gram-negative organisms. Parenteral vancomycin (or daptomycin in patients with acute renal failure or when organisms have reduced susceptibility to vancomycin) is the cornerstone of an empirical regime in settings with a high prevalence of methicillin-resistant ...

bacterial sepsis were gram-negative bacteria [4]. In the past 20 years, gram-positive bacteria, which are impor-tant pathogenic microorganisms that can also cause sep-sis, have gradually attracted attention [5]. At present, the harmfulness of sepsis caused by G (−) bacteria and G (+) bacteria is still controversial. One study suggested

2015年3月16日 · The aim was to analyze the Gram-negative bacteremia profile and the predisposing factors for length of stay in the surgical and medical ICU and outcome. Methods Retrospective data analysis of patients during 4 years treated in a surgical and medical ICU with positive blood culture for Gram-negative rod.

2019年3月9日 · This makes the clinical management of pneumonia caused by such pathogens a challenge for physicians. Taking into account the clinical severity that may be associated with CAP caused by Gram-negative bacteria (respiratory failure, bacteremia, shock, acute respiratory distress syndrome [ARDS]) the magnitude of the global health problem is tremendous.

2010年3月4日 · Introduction Bacteremia is recognized as a critical condition that influences the outcome of sepsis. Although large-scale surveillance studies of bacterial species causing bacteremia have been published, the pathophysiological differences in bacteremias with different causative bacterial species remain unclear. The objective of the present study is to investigate …

2008年5月21日 · Resistance rates are increasing among several problematic Gram-negative pathogens that are often responsible for serious nosocomial infections, including Acinetobacter spp., Pseudomonas aeruginosa, and (because of their production of extended-spectrum β-lactamase) Enterobacteriaceae. The presence of multiresistant strains of these organisms has …

2018年5月13日 · Background This study aimed to evaluate the accuracy of procalcitonin (PCT) serum concentrations to diagnose Gram-negative bacteremia and the association of PCT serum concentrations with more specific pathogens and the focus of infection. Methods Secondary analysis of the prospectively collected patient-level dataset from a cluster randomized quality …
