Article Abstract
Background: Clinical guidelines recommend extended venous thromboembolism (VTE) prophylaxis for cancer patients after major gastrointestinal (GI) operations. However, adherence to the guidelines has been low, and the clinical outcomes not well defined.
Methods: This study retrospectively analyzed a random 10 % sample of the 2009-2022 IQVIA LifeLink PharMetrics Plus database, an administrative claims database representative of the commercially insured population of the United States. The study selected cancer patients undergoing major pancreas, liver, gastric, or esophageal surgery. The primary outcomes were 90-day post-discharge VTE and bleeding.
Results: The study identified 2296 unique eligible operations. During the index hospitalization, 52 patients (2.2 %) experienced VTE, 74 patients (3.2 %) had postoperative bleeding, and 140 patients (6.1 %) had a hospital stay of at least 28 days. The remaining 2069 operations comprised 833 pancreatectomies, 664 hepatectomies, 295 gastrectomies, and 277 esophagectomies. The median age of the patients was 49 years, and 44 % were female. Extended VTE prophylaxis prescriptions were filled for 176 patients (10.4 % for pancreas, 8.1 % for liver, 5.8 % for gastric cancer, and 6.5 % for esophageal cancer), and the most used agent was enoxaparin (96 % of the patients). After discharge, VTE occurred for 5.2 % and bleeding for 5.2 % of the patients. The findings showed no association of extended VTE prophylaxis with post-discharge VTE (odds ratio [OR], 1.54; 95 % confidence interval [CI], 0.81-2.96) or bleeding (OR, 0.72, 95 % CI, 0.32-1.61).
Conclusions: The majority of the cancer patients undergoing complex GI surgery did not receive extended VTE prophylaxis according to the current guidelines, and their VTE rate was not higher than for the patients who received it.

Efficacy of Aspirin in Preventing Venous Thromboembolism in Total Knee and Hip Joint Replacement.

Background: Venous thromboembolism (VTE) is a significant complication following total knee arthroplasty (TKA) and total hip arthroplasty (THA). Aspirin has gained attention as a cost-effective, safe alternative to traditional anticoagulants like enoxaparin, but comparative data on efficacy and safety remain limited.
Methods: This randomized controlled trial compared the efficacy of aspirin and enoxaparin in preventing VTE following TKA and THA.

Introduction: Venous thromboembolism (VTE) is a relatively uncommon but potentially fatal complication following total knee arthroplasty (TKA). High altitude may induce physiological changes that can predispose patients to VTE. The purpose of this study was to determine if high altitude is an independent risk factor for postoperative VTE following TKA.

Introduction: In postmenopausal women who are estrogen deficient, hormone replacement therapy (HRT) has been shown to improve fragility fracture risk. However, few studies have examined the relationship between HRT and periprosthetic fracture (PPF) risk after total hip arthroplasty (THA). The purpose of this study was to determine the impact of HRT use on 10-year PPF risk following THA.

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.

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.
