Identifying biomarker-driven subphenotypes of cardiogenic shock: analysis of prospective cohorts and randomized controlled trials.

Background: Cardiogenic shock (CS) is a heterogeneous clinical syndrome, making it challenging to predict patient trajectory and response to treatment. This study aims to identify biological/molecular CS subphenotypes, evaluate their association with outcome, and explore their impact on heterogeneity of treatment effect (ShockCO-OP, NCT06376318).

Methods: We used unsupervised clustering to integrate plasma biomarker data from two prospective cohorts of CS patients: CardShock (N = 205 [2010-2012, NCT01374867]) and the French and European Outcome reGistry in Intensive Care Units (FROG-ICU) (N = 228 [2011-2013, NCT01367093]) to determine the optimal number of classes.

Left ventricular diastolic dysfunction is prevalent but not associated with mortality in patients with septic shock.

Purpose: Prognostic impact of left ventricular diastolic dysfunction (LVDD) in septic shock patients has not been determined using current diagnostic guidelines. We assessed the relation between LVDD during the first 3 days following intensive care unit (ICU) admission for septic shock and Day-28 mortality.

Methods: This prospective, multicenter, observational study enrolled 402 patients (age: 63 ± 13 year; 59% male; SAPS II: 59 ± 20; SOFA: 9.

Conventional Cytogenetic Analysis of Solid Tumor Abnormalities: A 25-Year Review of Proficiency Test Results from the College of American Pathologists/American College of Medical Genetics and Genomics Cytogenetics Committee.

The joint College of American Pathologists/American College of Medical Genetics and Genomics Cytogenetics Committee works to ensure the competency and proficiency of clinical cytogenetic testing laboratories through proficiency testing (PT) programs for various clinical tests offered by such laboratories, including the evaluation of cytogenetic abnormalities in solid tumors. Review and analyze 25 years (1999-2023) of solid tumor chromosome analysis PT results, utilizing G-banded karyograms. A retrospective review of results from 1999 to 2023 was performed, identifying the challenges addressing solid tumors.

Controversies in Timing of Surgery and Rehabilitation for Multiligamentous Knee Injuries.

With an estimated incidence of 0.02% to 0.2%, multiligamentous knee injuries are rare, often devastating injuries that can occur with concomitant vascular or neurologic involvement.
