s u m m a r yObjectives: Emergency room visits by nursing home patients with bloodstream infections (BSIs) are not uncommon and pose challenges to clinicians when selecting appropriate antimicrobial agents. This research aims to discover distinct bacteriology in nursing home patients by focusing particularly on antimicrobial-resistant bacteria. Methods: This retrospective study enrolled patients aged 65 years or older who had documented positive blood culture reports between May 2006 and June 2008. Patients were further categorized into subgroups according to nursing home history and the timely trend of hospital exposure. Results: The adjusted risk of BSIs associated with nursing home exposure was significantly higher in Methicillin-resistant Staphylococcus aureus (odds ratio (OR) 2.0; 95% CI 1.5e2.8), Methicillin-resistant coagulase-negative Staphylococcus species (OR 1.7; 95% CI 1.2e2.5), and Enterobacteriaceae-extended spectrum b-lactamase-producing Enterobacteriaceae (OR 2.4; 95% CI 1.5e3.9), but not in Pseudomonas aeruginosa (OR 1.4; 95% CI 0.9e2.2) or Acinetobacter baumannii (OR 0.9; 95% CI 0.5e1.5). Conclusion: Host environmentsdnursing home or hospital exposuredwere shown to be more significant than medical comorbid conditions for acquiring antimicrobial-resistant pathogens. Each unique environment increased the risk for acquiring some pathogens, but not all. In addition, these environmental factors may also exert cumulative effects toward some specific pathogens.
s u m m a r y A 68-year-old male complained of epigastric pain and coffee ground vomitus for hours. Emergent panendoscopy revealed diffuse esophageal ulcers, mild hiatal hernia, and gastric erosion. An abdominal computed tomography (CT) scan was performed due to the persistent abdominal pain with peritonitis. CT scan without enhancement showed transmesenteric internal herniation of the small bowel with strangulation. The condition of the patient deteriorated and he died from extreme shock and peritonitis after 3 hours of observation in the surgical intensive care unit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
