Abstract: The aetiology and risk factors for clinically important gastrointestinal bleeding (CIB) in adult ICU patients may differ according to the onset of CIB, which could affect the balance between benefits and harms of stress ulcer prophylaxis (SUP). We assessed the time to CIB in the Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU) trial. We assessed if associations between baseline characteristics including allocation to SUP and CIB changed during time in the ICU, specifically in the later (after day 2) compared to the earlier (first 2 days) period, using Cox models adjusted for SAPS II and allocation to SUP. Additionally, we described baseline characteristics and CIB episodes stratified by earlier/later/no CIB and 90-day mortality status. Clinically important gastrointestinal bleeding occurred in 110/3291 (3.3%) patients after a median of 6 (interquartile range 2-13) days 25.5% of the episodes occurred early. Higher SAPS II was consistently associated with increased risk of CIB (hazard ratio (HR) 1.03, 95% confidence interval (CI) 1.01-1.05 in the earlier period vs HR 1.02, 95% CI 1.01-1.03 in the later period P = .37) university hospital admission was associated with decreased risk of earlier CIB (HR 0.30, 95% CI 0.14-0.63) this significantly increased in the later period (to HR 0.85, 95% CI 0.53-1.37 P = .02). Patients with later compared to earlier CIB received more transfusions and had more diagnostic/therapeutic procedures for CIB. Clinically important gastrointestinal bleeding mostly occurred more than 2 days after randomization. University hospital admission was associated with significantly decreased risk of CIB in the earlier period only.

Abstract: A family of three neutral iridium(III) tetrazolato complexes are investigated as bacterial imaging agents. The complexes offer a facile tuning of the emission colour from green (520 nm) to red (600 nm) in aqueous media, while keeping the excitation wavelength unchanged. The three complexes do not inhibit the bacterial growth of Bacillus Cereus, used as a model in this study, and exhibit extremely fast cellular uptake. After a minute incubation time, the nontoxic complexes show subcellular localisation in spherical structures identified as lipid vacuoles. Confocal Raman imaging has been exploited for the first time on live bacteria, to provide direct and label-free mapping of the lipid-enriched organelles within B. cereus, complementing the use of luminescent probes. Examination of the Raman spectra not only confirmed the presence of lipophilic inclusions in B. cereus but offered additional information about their chemical composition, suggesting that the lipid vacuoles may contain polyhydroxybutyrate (PHB).

Abstract: The utility of dendrimers as effective carriers for targeted drug delivery and imaging has been facilitated by a high degree of molecular uniformity, narrow molecular weight distribution, tunable size and shape characteristics, and multivalency. Dendrimer–quantum dot (QD) nanocomposites have traditionally been synthesised by electrostatic self-assembly of preformed dendrimers and QDs, but higher generations are associated with limited flexibility and increased cytotoxicity. In this paper, we report the fabrication of CdTe QD nanoparticles using a dendronised linear copolymer bearing thiolated fourth-generation poly(amido amine) (PAMAM) dendrons as the capping and stabilising agent. We demonstrate this approach enables synthesis of nanocomposites with aqueous and photophysical stability.
