Point-of-care tests, diagnostic uncertainty and antimicrobial stewardship in the ICU: procalcitonin or PCR to aid antibiotic-stop decisions - an observational cohort study.

Objectives: Intensive care unit (ICU) clinicians stop antibiotics more often, with a negative infection: point-of-care test (PCR-POCT). Simulated cases of diagnostic uncertainty regarding infection resolution led clinicians to choose options such as procalcitonin (PCT) and/or PCR-POCTs +/- de-escalation to aid stop decisions. We hypothesised that a direct infection indicator, PCR-POCT, would influence stop judgements more than indirect PCT.

Widespread 3D genome reorganization precedes programmed DNA rearrangement in .

Genome organization recapitulates function, yet ciliates like possess highly-specialized germline genomes, which are largely transcriptionally silent. During post-zygotic development, 's germline undergoes large-scale genome editing, rearranging precursor genome elements into a transcriptionally-active genome with thousands of gene-sized nanochromosomes. Transgenerationally-inherited RNAs, derived from the parental somatic genome, program the retention and reordering of germline fragments.

Toxicological evaluation of imidazo-based heterocyclic derivatives: and acute toxicity studies.

Imidazo based heterocyclic derivatives are considered as privileged scaffolds due to their presence in various pharmacologically active compounds and in marketed formulations. The present study reports toxicological evaluation of three imidazo based heterocyclic derivatives which are currently being investigated for their potential anticancer activity. Compounds IG-01-007, IG-01-008, and IG-01-009 were assessed for cytotoxicity, hemolysis, and DNA fragmentation activity.

The Hallmarks of Predictive Oncology.

As the field of artificial intelligence evolves rapidly, these hallmarks are intended to capture fundamental, complementary concepts necessary for the progress and timely adoption of predictive modeling in precision oncology. Through these hallmarks, we hope to establish standards and guidelines that enable the symbiotic development of artificial intelligence and precision oncology.

Practice-pattern variation in anticoagulation intensity in acute cerebral venous thrombosis: A two-center experience.

Background And Purpose: Cerebral venous thrombosis (CVT) requires acute anticoagulation. Heparin is commonly used but specific recommendations on intensity and timing are lacking. We sought to characterize practice-pattern variation in the use of unfractionated heparin (UFH) for acute CVT treatment across multiple centers.
