Computed Tomography Yield and Predictors of Pulmonary Embolism in Mechanically Ventilated Patients—A Retrospective Study

open access: yesActa Anaesthesiologica Scandinavica, Volume 70, Issue 4, April 2026.
ABSTRACT Background The reported prevalence of pulmonary embolism (PE) detected during intensive care varies substantially. Computed tomography pulmonary angiography (CTPA) is the diagnostic reference method, but assessing pre‐test probability and finding distinct indications for CTPA from clinical observations is difficult in mechanically ventilated ...

Classification of Platelet‐Activating Anti‐Platelet Factor 4 Disorders

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 2, Page 259-271, April 2026.
ABSTRACT Introduction The prototypic anti‐platelet factor 4 (PF4) disorder—heparin‐induced thrombocytopenia and thrombosis (HITT)—features immunoglobulin G (IgG) class antibodies that activate platelets, monocytes, and neutrophils in a mainly heparin‐dependent fashion via Fcγ receptor‐dependent cellular activation.

A Retrospective Study of Adult and Pediatric D‐Dimer Tests to Identify Opportunities for Improved Utilization

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 2, Page 392-401, April 2026.
ABSTRACT Introduction D‐dimers are produced by lysis of cross‐linked fibrin. In children, D‐dimer testing is used to evaluate disseminated intravascular coagulation (DIC) and some inflammatory states, but its use is not validated for screening or ruling out suspected venous thromboembolic events (VTE).
