Venous Thromboembolism and Chronic Pain After Major Limb Trauma

Major limb trauma is associated with a high risk of venous thromboembolism (VTE) due to systemic inflammation, endothelial injury, immobilization, and hypercoagulability. While VTE is commonly studied as a short-term complication affecting morbidity and mortality, its potential relationship with long-term pain outcomes after trauma has not been well investigated. This prospective observational cohort study aims to evaluate whether objectively confirmed VTE is associated with an increased risk of persistent clinically significant pain after major limb trauma. Adult patients with severe upper or lower limb injuries requiring surgical treatment or prolonged immobilization will be enrolled within 72 hours of hospital admission and followed for six months. The study will assess whether patients who develop VTE have a higher likelihood of persistent pain compared with those without VTE. In addition, the study will explore the association between baseline VTE risk (using the Trauma Embolic Scoring System, TESS), thromboprophylaxis timing, and long-term pain outcomes. Secondary analyses will evaluate neuropathic pain symptoms, pain interference with daily activities, quality of life, opioid consumption, and functional recovery. Understanding the relationship between thromboembolic complications and persistent pain may help improve risk stratification, optimize thromboprophylaxis strategies, and support early rehabilitation planning in patients with major limb trauma.

A Clinical Trial on the Outcomes of Comprehensive Enhanced Prophylaxis Management (CEPM) in Chinese Patients With EGFR-Mutated Advanced NSCLC Receiving Amivantamab-Based Regimens

This study aims to explore the clinical outcomes of Comprehensive Enhanced Preventive Management (CEPM) combined with an amivantamab-containing treatment regimen in Chinese patients with EGFR-mutated advanced NSCLC.

DOAC - Dosing Options in AntiCoagulation Prophylaxis

Blood clots, also known as venous thromboembolism (VTE), are a common and serious complication for people with cancer. They can lead to pain, hospitalizations, delayed cancer treatment, and even death. Although national guidelines recommend using blood thinners (anticoagulants) to prevent clots in cancer patients who are at higher risk, these medications are not commonly prescribed due to concerns about bleeding and inconvenience. This study will test different ways of using a commonly prescribed blood thinner called apixaban (brand name Eliquis) to see if it can safely and effectively reduce the risk of blood clots and death in cancer patients who are at moderate risk for VTE. The study focuses on people who have a "Khorana score" of 2, which puts them at intermediate risk for developing blood clots. The study will include approximately 996 participants with solid tumors or lymphoma who are starting or recently started cancer-directed therapy. Participants will be randomly assigned to one of three groups: Group 1: Apixaban 2.5 mg twice a day (standard prophylactic dose) Group 2: Apixaban 5 mg once a day (an alternative, more convenient dose) Group 3: No anticoagulant (standard care) Participants will take the assigned treatment (if applicable) for 6 months. Researchers will monitor whether participants develop blood clots, experience serious bleeding events, or die from any cause during the study period. By comparing these three groups, the researchers hope to learn whether a once-daily dose of apixaban can work as well as the standard twice-daily dose, and whether either dosing strategy is better than no anticoagulation at all. If successful, the study may help increase the safe use of VTE prevention in cancer patients and improve overall outcomes, especially in patients at intermediate risk. This is a pragmatic trial, meaning it is designed to fit into real-world clinical practice with minimal extra procedures. The study drug is not provided by the sponsor and will be prescribed and filled through usual care channels. Participants and their doctors will decide whether to continue the medication after the study ends.

Reduced-Dose Apixaban and Rivaroxaban Versus Low-Molecular-Weight Heparin in Patients With Hematologic Malignancies

This study investigates the efficacy and safety of direct oral anticoagulants (DOACs) in comparison with standard low-molecular-weight heparin (LMWH) for the prevention of venous thromboembolism in patients with hematological malignancies. Eligible participants will be randomized to receive reduced-dose apixaban, reduced-dose rivaroxaban, or standard-dose LMWH. The primary objective is to evaluate the incidence of venous thromboembolism during a 6-month follow-up period. Secondary objectives include assessment of bleeding complications, overall survival, and treatment adherence. The results of this study may provide evidence for safer and more convenient thromboprophylaxis strategies in patients with blood cancers.

Excretion of Rivaroxaban in Human Breast Milk

The purpose of this study is to investigate the distribution of rivaroxaban into human milk at both therapeutic and prophylactic doses, and over time with repeated dosing.

Padua Prediction Score for VTE Risk in Thoracic Surgery Patients

The goal of this observational study is to assess the predictive accuracy of the Padua Prediction Score (PPS) for venous thromboembolism (VTE) risk in thoracic surgery patients. The study aims to answer the following question: Does the PPS provide a more accurate prediction of VTE risk? Participants will: Have their VTE risk assessed using the PPS during their hospital admission.

AQT90 FLEX D-dimer Clinical Sensitivity and Specificity

The goal of this study is evaluate the clinical performance of the AQT90 FLEX D-dimer Test as an aid in the diagnosis of Venous Thromboembolism.

A Multicenter, Open-Label, Non-Inferiority Randomized Controlled Trial of Postoperative VTE Prevention in Chinese Patients After Colorectal Cancer Surgery

research objective 1. Optimize VTE prevention management after CRC surgery. 2. Improve the prevention and treatment level of VTE in current perioperative patients. 3. Reduce the social burden of VTE related diseases. Participants will: 1. start low molecular weight heparin prophylaxis within 24 hours post-surgery. 2. The prophylactic regimen for the experimental group lasted 14 days, while the control group received it for 28 days. Low molecular weight heparin is given subcutaneously at a dose of 0.3ml once daily. 3. atients underwent lower limb color Doppler ultrasound on postoperative days 7 ± 2, 14 ± 3, and 28 ± 5, which included screening for thrombosis in the proximal deep veins (femoral, popliteal), distal deep veins (posterior tibial, fibular, and muscular veins), and their perforating branches.
