Objective: To analyze an effectiveness of algorithm for complex treatment of patients with surgical complications of prolonged warfarin therapy in a general surgical hospital.
Material And Methods: The study included 138 patients with surgical complications of prolonged warfarin therapy. All patients received warfarin for at least 6 months (49.5% of patients - over 5 years). Warfarin therapy was indicated for deep vein thrombosis in 54 patients and various cardiac diseases in 84 patients. Examination included clinical and instrumental survey, laboratory tests and coagulation tests - thromboelastography (TEG) and thrombodynamics test (TT).
Results: Recurrent VTEC occurred in 24 out of 138 patients, hemorrhagic complications - in 114 patients. Therapeutic management was applied in 111 patients, 27 ones underwent surgery (emergency treatment - 25 patients, after two days - 2 patients). Ten patients underwent endoscopic hemostasis, two patients - ultrasound-assisted percutaneous drainage of hematoma. Recurrent VTECs were caused by inadequate laboratory control and violations of warfarin therapy. Most of these patients underwent therapeutic management (only 3 patients required surgery for life-threatening flotation in great veins). Treatment of 114 patients with hemorrhagic complications of prolonged warfarin therapy depended on features of bleeding and severity of warfarin-induced coagulopathy. Depending on these factors, warfarin was discontinued and intravenous administration of vitamin K / FFP / prothrombin complex concentrate was applied. This approach ensured successful therapeutic measures in 90 patients of this group. Twenty-four patients underwent surgery after correction of hemostatic disorders. TT was characterized by high efficiency in analysis of thrombotic predisposition and prediction of the risk of VTEC. TEG was valuable for assessment of warfarin-induced coagulopathy and treatment of patients with hemorrhagic complications of prolonged warfarin therapy.
Conclusion: The developed clinical and diagnostic algorithm for management of hemorrhagic complications of prolonged warfarin therapy ensures positive clinical results even in a general surgical hospital.

Clinical effectiveness and safety comparison between direct oral anticoagulants and warfarin for nonvalvular atrial fibrillation patients following percutaneous left atrial appendage closure operation intervention: a prospective observational study.

The main objective of this study was to investigate the optimal post-left atrial appendage closure (LAAC) anticoagulation strategy, focusing on minimizing device-related thrombosis (DRT) and thromboembolism (TE) events without increasing bleeding risk. After successful LAAC, consecutive participants were treated with 45-day anticoagulants (rivaroxaban 15 mg daily, dabigatran 110 mg twice a day, and warfarin). The efficacy endpoints included DRT, TE, and hospital readmissions due to cardiac caused, while safety endpoints encompassed bleeding events, monitored over a 12-month follow-up period.

This review summarizes recent case reports where the consumption of dietary supplements by older adults may have caused an adverse event. In December 2023, PubMed was surveyed for case reports published from 2000 onwards, using two medical subject heading (MeSH) terms, "aged" and "dietary supplements," where the latter was combined with the MeSH subheadings "adverse effects," "poisoning," or "toxicity."

Medicine and Surgery, Khyber Medical University, Peshawar, PAK.
Background: The management of thromboembolic risk and the necessity for timely hemorrhage control make anticoagulant-related gastrointestinal (GI) bleeding clinically challenging.
Objective: This study aimed to evaluate clinical outcomes (such as bleeding control and mortality) and the effectiveness of anticoagulation reversal techniques in patients with anticoagulant-related GI bleeding in emergency settings.
Methodology: This prospective, observational study conducted at Lady Reading Hospital, Peshawar, from January to December 2023, included patients aged 18 or older with GI bleeding on warfarin or direct oral anticoagulants (DOACs).

Article Synopsis
- Obesity is a significant risk factor for venous thromboembolism (VTE) and poses unique challenges in anticoagulation management due to limited research on how extreme body weight affects medication outcomes.
- This review focuses on patients with a body mass index (BMI) of 40 kg/m² or higher, analyzing various anticoagulants' dosages, efficacy, and safety for both prevention and treatment of VTE.
- The study emphasizes the need for personalized treatment strategies and careful monitoring, especially for specific groups like cancer patients or those with kidney issues, given the insufficient evidence available for effective anticoagulant therapy in morbidly obese individuals.
