Patients who are immunocompromised (IC) at increased risk of Clostridium difficile infection (CDI), which has to epidemic proportions over the past decade. Fecal microbiota transplantation (FMT) appears effective for treatment CDI, although there is concern that IC patients may be having adverse events (AEs) related FMT. This study describes multicenter experience FMT in patients.A retrospective series was performed on use with CDI recurrent, refractory, or severe. We aimed describe rates...
Klebsiella pneumoniae is among the most common causes of hospital-acquired infections and has emerged as an urgent threat to public health due carbapenem antimicrobial resistance. K. commonly colonizes hospitalized patients extraintestinal such urinary tract infection, bloodstream infection (septicemia), pneumonia. If colonization intermediate step before then detection characterization colonizing isolates could enable strategies prevent or empirically treat in patients. However, strength...
Midpoint potentials of plant-type ferredoxins from a range sources were measured by redox titrations combined with electron-paramagnetic-resonance spectroscopy. For higher plants, green algae and most red algae, the midpoint (at pH 8.0) between —390 —425 mV. Values for major ferredoxin fractions blue-green less negative (between —325 mV). In addition, Spirulina maxima Nostoc strain MAC contain second minor components different potential, —305 mV (the highest so far plant-algal ferrodoxin)...
Background. Clostridium difficile infection (CDI) can cause severe disease and death, especially in older adults. A better understanding of risk factors for adverse outcomes is needed. This study tests the hypotheses that with specific ribotypes presence stool toxins independently associate severity constructs predictive models outcomes.
OBJECTIVE An estimated 293,300 healthcare-associated cases of Clostridium difficile infection (CDI) occur annually in the United States. To date, research has focused on developing risk prediction models for CDI that work well across institutions. However, this one-size-fits-all approach ignores important hospital-specific factors. We focus a generalizable method building facility-specific models. demonstrate applicability using electronic health records (EHR) from University Michigan...
1. The Mössbauer spectra of Scenedesmus ferredoxin enriched in 57Fe were measured and found to be identical with those two other plant-type ferredoxins (from spinach Euglena) that had been previously measured. Better resolved are also reported from protein 57Fe. All these iron–sulphur proteins known contain iron atoms a molecule takes up one electron on reduction. 2. at 195°K have electric hyperfine structure only show reduction the goes atoms, appearing remain unchanged. 3. In oxidized...
Recurrent Clostridium difficile infection (CDI) remains problematic, with up to 30 % of individuals diagnosed primary CDI experiencing at least one episode recurrence. The success microbial-based therapeutics, such as fecal microbiota transplantation, for the treatment recurrent underscores importance restoring microbiota. However, few studies have looked microbial factors that contribute development disease. Here we compare changes over time in patients or without recurrence identify...
Abstract Despite enhanced infection prevention efforts, Clostridioides difficile remains the leading cause of healthcare-associated infections in United States. Current strategies are limited by their failure to account for patients who carry C. asymptomatically, may act as hidden reservoirs transmitting other patients. To improve understanding asymptomatic carriers’ contribution spread, we conducted admission and daily longitudinal culture-based screening a US-based intensive care unit over...
Abstract The production of the microalga Phaeodactylum tricornutum in an outdoor helical reactor was analyzed. First, fluid dynamics, mass‐transfer capability, and mixing evaluated at different superficial gas velocities. Performance controlled by power input per culture volume. A maximum liquid velocity 0.32 m s −1 mass transfer coefficient 0.006 were measured 3200 W −3 . model influence on following parameters proposed: hold‐up, induced velocity, coefficient, with accuracy being...

Lattice-parameter variations as a function of temperature for silver–palladium alloys five different compositions were investigated using high-temperature 19-cm Unicam X-ray camera. Alloys containing 63 wt. % Ag and 80 show straight-line relationship between lattice parameter temperature.Measurements made at room on specimens quenched from temperatures, after maintaining them periods time each particular temperature, indicate no changes in the lattice-parameter values. It is suggested that...
1. A stable ferredoxin was prepared from Bacillus stearothermophilus and purified by chromatography on DEAE-cellulose electrophoresis. 2. The minimum molecular weight determined the amino acid composition about 7900 this in reasonable agreement with a value of 8500 polyacrylamide-gel contained four iron atoms labile sulphide groups per molecule. 3. optical absorption, optical-rotatory-dispersion circular-dichroism spectra are typical ferredoxins containing 4Fe-4S clusters. 4....
To identify maternal deaths due to sepsis in the state of Michigan, review events leading diagnosis, and evaluate treatment areas for improvement.A case series was collected from a cohort Michigan. The study period 1999-2006 included during pregnancy up 42 days postpartum. Cases were identified using Maternal Mortality Surveillance records Michigan Department Community Health. Each reviewed by all authors.Maternal cause death 15% (22/151) pregnancy-related deaths. Of 22 deaths, 13 women...
