We examined the possibility that decreased environmental oxygen can elevate the levels of indigenous bacteria in the hemolymph of Cancer magister. Crabs were exposed to air-saturated and hypoxic (50% air-saturation) water for 3 days and levels of culturable bacteria in hemolymph were measured every
Cerebral abscess is a recognized complication of pulmonary arteriovenous malformations (PAVMs) that allow systemic venous blood to bypass the pulmonary capillary bed through anatomic right-to-left shunts. Broader implications and mechanisms remain poorly explored.
Between June 2005 and December
OBJECTIVE
To assess the relationship of WBC counts and partial oxygen tension in the portal vein and caudal vena cava with portal bacteremia, bacteria in the liver, and postoperative morbidity and mortality in dogs with portosystemic shunts.
METHODS
Prospective study.
METHODS
12 clinically normal
Pulmonary effects, lung clearance, and tissue retention of blood-borne Pseudomonas aeruginosa were compared in dogs (n = 5) and pigs (n = 5) during continuous 6-hour intravenous infusion of 1.2(10(9)) bacteria/min/20 kg. Control pigs received an equal volume of sterile saline. In contrast to
OBJECTIVE
We sought to determine if preterm labor is associated with the degree of maternal hypoxia in pregnant women with community-acquired pneumonia but no other maternal diseases.
METHODS
We retrospectively reviewed the medical records of all antepartum patients admitted with a diagnosis of
Although Streptococcal bacteremia is common in diarrheal children with high morbidity and mortality, no systematic data are available on Streptococcal bacteremia in diarrheal children. We sought to evaluate the factors associated with Streptococcal bacteremia in diarrheal children under five years
OBJECTIVE
In patients who require extracorporeal membrane oxygenation for prolonged periods, it is uncertain whether nosocomial bacteremia that persists throughout an entire extracorporeal membrane oxygenation run can be associated with good outcomes.
METHODS
Case report.
METHODS
Tertiary pediatric
Group B beta-hemolytic streptococcus (GBS) causes thromboxane (Tx)-associated pulmonary hypertension and hypoxemia in neonatal animals and human infants. The components of GBS that induce these features of sepsis are incompletely characterized. The capsular polysaccharide has been implicated based
Bacteremia, or the presence of live bacteria in the bloodstream, does not seem a prerequisite for septic shock. Indeed, only a small portion of all patients who sustain gram-negative bacteremia ever develop the shock syndrome. Endotoxin in the laboratory model is capable of producing a number of
BACKGROUND
Acute lung injury is a common complication of gram-negative sepsis. Pulmonary hypertension and increased lung vascular permeability are central features of lung injury following experimental bacteremia. Platelet-activating factor is a prominent proinflammatory mediator during bacterial
Episodes of tissue hypoxia and reoxygenation frequently occur during gram-negative bacteremia that progresses to septic shock. However, few studies have evaluated modulation by hypoxia and reoxygenation of the proinflammatory cytokine gene expression that is normally induced by gram-negative
CONCLUSIONS
Balloon-assisted enteroscopy (BAE) is an emerging standard procedure by utilizing distensible balloons to facilitate deep endoscopy in the small and large intestine. Sporadic cases of bacteraemia were found after BAE. Balloon distension by BAE caused gut tissue hypoxia. The impact of
We tested the hypothesis that reducing the hepatic O2 supply by 30 min of constant-flow hypoxia (PO2, approximately 45 Torr) following gram-negative bacteremia downregulates tumor necrosis factor-alpha (TNF-alpha) in buffer-perfused rat lives (total n = 44). Eight groups were studied after
BACKGROUND
The diagnostic yield of blood cultures is limited in patients with community-acquired pneumonia (CAP). Yet, positive blood culture results provide important information for antibiotic treatment and for monitoring epidemiologic trends. We investigated the potential of clinical predictors
Thromboxane-associated pulmonary hypertension occurs in animals during intravenous infusion of group B streptococcus (GBS), a gram-positive neonatal pathogen. We postulated that other gram-positive neonatal pathogens, such as Streptococcus fecalis (ENT) and Staphylococcus epidermidis (S. epi) would
