AI Article Synopsis
Article Abstract
Point-of-care testing (POCT) for D-dimer is an alternative to -laboratory testing for the exclusion of venous thromboembolism (VTE). This critical review by the "CEC et biologie délocalisée" working group of the "Société Française de Thrombose et d'Hémostase" (French Society of -Thrombosis and Haemostasis) aims to present the characteristics of six POCT D-dimer assays available in France in 2023. The article highlights the need to define VTE -exclusion thresholds specific to each technique and validated by clinical studies. There is insufficient data to validate the use of cut off suggested by manufacturers, and age-adjusted thresholds. The article discusses the role of laboratories in justifying and prescribing POCT D-dimer, according to objective criteria, such as the availability and turnaround time of classical laboratory tests. They should also encourage rational prescribing, limited to patients with low risk of venous thromboembolism, following an assessment of clinical probability according to national and international guidelines.

Introduction: Low rates of venous thromboembolism (VTE) have been found in patients with isolated orthopaedic trauma below the knee. Many surgeons routinely provide chemical thromboprophylaxis in these injuries, however. This is not without inherent risks, and this remains a controversial topic in perioperative care in orthopaedic trauma.

Objective: To develop and validate a nomogram for predicting non-retrieval of the short-term retrievable inferior vena cava (IVC) filters.
Methods: In this study, univariate and multivariate logistic regression analyses were performed to identify predictive factors of short-term retrievable filter (Aegisy or OptEase) non-retrieval, and a nomogram was then established based on these factors. The nomogram was created based on data from a training cohort and validated based on data from a validation cohort.

Neuromuscular Electrical Stimulation (NMES) uses electrical impulses to induce muscle contractions, providing benefits in rehabilitation, muscle activation, and as an adjunct to exercise, particularly for individuals experiencing immobilization or physical disability. NMES technology has significantly progressed, with advancements in device development and a deeper understanding of treatment parameters, such as frequency, intensity, and pulse duration. These improvements have expanded NMES applications beyond rehabilitation to include enhanced post-exercise recovery, improved blood glucose uptake, and increased lower limb venous return, potentially reducing thrombotic risks.

Venous thromboembolism (VTE) is still a major challenge after major orthopaedic surgery, including total knee replacement (TKR). The aim of this study was to estimate the risk of VTE with aspirin-only pharmacologic prophylaxis following primary TKR surgery versus direct oral anticoagulant (DOAC). The study included 476 patients who underwent primary TKR from 2016 to 2020.

Background: Venous thromboembolic events (VTEs) are the second-leading cause of death in cancer patients, with an incidence of 5%-17% in lymphoma patients, particularly higher in those with non-Hodgkin lymphoma (NHL). Existing risk assessment models (RAMs) like the Khorana and ThroLy scores have limitations and are inadequately validated for NHL patients. Coagulation markers such as D-dimer, thrombin-antithrombin complex (TAT), and thrombomodulin (TM) show a potential predictive value for cancer-associated VTE but lack extensive research in NHL.
