Self-Reported Penicillin Allergy and antibiotic use in critical care: An observational, retrospective study.

Background: Patients with Self-Reported Penicillin Allergy (SRPA) receive alternative antibiotics, which increase the length of stay and hospital costs, but the impact of SRPA on mortality in critically ill patients is not well described.

Methods: This was a single-center, retrospective analysis of routinely gathered clinical data for all intensive care unit (ICU) admissions over nine years. The primary outcome was 28-day mortality, which was analyzed using a time-to-event approach with multivariable models to adjust for confounding factors, including age, comorbidities, sex, and admission SOFA score (as a measure of organ dysfunction).

Biomarker-Guided Antibiotic Duration for Hospitalized Patients With Suspected Sepsis: The ADAPT-Sepsis Randomized Clinical Trial.

Importance: For hospitalized critically ill adults with suspected sepsis, procalcitonin (PCT) and C-reactive protein (CRP) monitoring protocols can guide the duration of antibiotic therapy, but the evidence of the effect and safety of these protocols remains uncertain.

Objective: To determine whether decisions based on assessment of CRP or PCT safely results in a reduction in the duration of antibiotic therapy.

Design, Setting, And Participants: A multicenter, intervention-concealed randomized clinical trial, involving 2760 adults (≥18 years), in 41 UK National Health Service (NHS) intensive care units, requiring critical care within 24 hours of initiating intravenous antibiotics for suspected sepsis and likely to continue antibiotics for at least 72 hours.

Mortality in septic patients treated with short-acting betablockers: a comprehensive meta-analysis of randomized controlled trials.

Background: Treatment with short-acting betablockers in septic patients remains controversial. Two recent large multicenter trials have provided additional evidence on this therapeutic approach. We thus performed a meta-analysis, including the most recent data, to evaluate the potential impacts of treatment with short-acting betablockers on mortality in adult septic patients.

Longitudinal genomic surveillance of a UK intensive care unit shows a lack of patient colonisation by multi-drug-resistant Gram-negative bacterial pathogens.

Vulnerable patients in an intensive care unit (ICU) setting are at high risk of infection from bacteria including gut-colonising and species. Complex ICU procedures often depend on successful antimicrobial treatment, underscoring the importance of understanding the extent of patient colonisation by multi-drug-resistant organisms (MDROs) in large UK ICUs. Previous work on ICUs globally uncovered high rates of colonisation by transmission of MDROs, but the situation in UK ICUs is less understood.

Dietary fat lowers ileal endogenous amino acid losses in broiler chickens.

1. An experiment was conducted to determine the effect of the source of fat (soybean oil or tallow) on the ileal endogenous amino acid (EAA) losses in broilers.2.
