The current status of reversal therapy in Japan for elderly patients with head injury treated with antithrombotic agents: A prospective multicenter observational study. Heliyon 2024; 10:e25193. [PMID: 38318008 PMCID: PMC10839600 DOI: 10.1016/j.heliyon.2024.e25193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 12/18/2023] [Accepted: 01/22/2024] [Indexed: 02/07/2024] Open
Abstract
Background Acute exacerbation of head injury in elderly patients due to use of antithrombotic agents has become a concern in countries with aging populations. Reversal agents are recommended for treatment, but its usage is unclear. Therefore, we conducted a prospective observational study in this patient population to monitor usage of reversal therapy. Methods The subjects were 721 elderly patients aged ≥65 years old who were hospitalized in 15 centers from December 2019 to May 2021. Patients were divided into groups who did not receive antithrombotic agents (Group A), who received antithrombotic agents, but did not receive reversal therapy (Group B), and were treated with antithrombotic agents and reversal therapy (Group C). Age, gender, mechanism of injury, neurologic and imaging findings on admission, clinical course after admission and surgery, outcomes and complications were compared among these groups. Time from injury to reversal therapy was examined based on outcomes to investigate trends in the timing of administration of the reversal agent. Results Acute exacerbation during the clinical course occurred in 9.8 %, 15.8 % and 31.0 % of cases in Groups A, B and C, respectively, and differed significantly among the groups. On head CT, the incidences of hematoma were 35.7 %, 36.5 % and 60.4 %, respectively, with this incidence being significantly higher in Group C; and the respective rates of craniotomy were 18.8 %, 14.0 % and 50.9 %, again with this rate being significantly higher in Group C. The good outcome and mortality rates were 57.1 %, 52.5 % and 35.8 %, and 14.5 %, 18.0 % and 24.5 %, respectively, and both were poorest in Group C. Times from injury to treatment with a reversal agent were significantly shorter in patients without compared to those with acute exacerbation (405.9 vs. 880.8 min) and in patients with favorable outcomes compared to those with unfavorable outcomes (261.9 vs. 543.4 min). Conclusion Similarly to previous studies, the incidence of acute exacerbation was increased by use of antithrombotic agents. These results suggest that patients in Japan who require hematoma evacuation due to symptom exacerbation tend to be treated with reversal agents. Although it is difficult to assess the efficacy of reversal therapy from this study, earlier treatment with reversal agents before the occurrence of acute exacerbation may be useful to improve outcomes.

Abstract
ABSTRACT Direct oral anticoagulants have been used in the adult population for years and are being used more frequently in pediatrics. Direct oral anticoagulants are chosen preferentially because they do not require close outpatient monitoring, have an equal or better safety profile, and are easy for patients to take. Warfarin is the previous, more commonly used oral anticoagulant and acts as a vitamin K antagonist. Direct oral anticoagulants mechanism of action is different in that they directly inhibit part of the coagulation cascade accomplishing the same end goal. Given their differing mechanisms, they require alternate medications for proper reversal when concerned about overdose of life-threatening bleeds. This review will outline the most commonly used direct oral anticoagulants in pediatric populations and the supporting (mainly adult) data available for proper reversal of these medications in times of need.

Abstract
The objective of this systematic review is to assess the risk of postoperative bleeding in oral surgery for implant placement in individuals taking antithrombotics (i.e., anticoagulants and/or antiplatelet agents). A literature search was performed in PubMed (MEDLINE), Web of Science, Scopus, and EMBASE databases for articles published until August 2020, with no date restriction, and manually completed. We included prospective clinical studies that provided information regarding the presence of an experimental group (i.e., implant placement), a control group (patients not under treatment with antithrombotics), and a well-established protocol for evaluating bleeding. Meta-analysis determined the risk of bleeding during the placement of implants in antithrombotic-treated patients. Of the 756 potentially eligible articles, 5 were included in the analysis with 4 ranked as high and 1 as medium quality. Antithrombotic treatment comprised the following drug classes: (1) anticoagulants: vitamin K antagonists, (2) nonvitamin K antagonist oral anticoagulants, (3) low-molecular-weight heparin, and (4) antiplatelet agents (not specified). The results suggest that the risk of bleeding is not substantially higher in antithrombotic-treated patients (odds ratio = 2.19; 95% confidence interval: 0.88-5.44, p = 0.09) compared with nontreated patients. This systematic review suggests that the absolute risk is low and there is no need to discontinue or alter the dose of the antithrombotic treatment for implant placement surgery.

Abstract
This article explores how to prevent and manage complications of dentoalveolar surgery. Many complications are avoidable. Surgical skills and knowledge of anatomy play an important role in prevention of complications. Prevention starts with detailed history and physical examination of the patient. Key to perioperative management of patients is risk assessment. Without a proper history and physical examination, the clinician is unable to assess the risk of performing surgery and anesthesia for each patient. Some illnesses and medications increase the risk of complications. The following complications are discussed: alveolar osteitis, displacement, fracture, hemorrhage, infection, nonhealing wound, oroantral communication, swelling, and trismus.

Abstract
Use of anticoagulant therapy has increased in patients presenting for ophthalmic surgery over the past decade. The decision of whether or not to discontinue anticoagulant medications prior to ophthalmic surgeries is nuanced and ultimately based on multiple factors including the type of surgery and the patient’s comorbidities and risk profile. In the setting of cataract surgery, no increased risk of bleeding with anticoagulation was observed in a large prospective study, which suggests that anticoagulation should not be interrupted for the average-risk patient on anticoagulation. In other types of ophthalmic surgery, expert opinion and studies are divided on the perioperative management of anticoagulant therapy. Preoperative thromboembolic risk stratification, intraoperative techniques to minimize bleeding, and postoperative management are also reviewed to generate more comprehensive recommendations on ophthalmic perioperative management of anticoagulation.
