This article reports a case of primary total knee arthroplasty for osteoarthritis in a patient who underwent treatment 20 years previously for a large giant cell tumor presenting with an intraarticular knee fracture. The arthroplasty was made technically challenging by the abnormal shape of the distal femur. The reconstruction was facilitated by the use of stemmed components and autogenous bone graft. The medium-term results are encouraging. This case suggests a good outcome can be achieved in the presence of distorted distal femoral anatomy.

Assessment of simulation training efficacy in improving microsurgical skills: a retrospective analysis.
Int J Surg
January 2025
Department of Orthopaedics, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Background: Microsurgery demands an intensive period of skill acquisition due to its inherent complexity. The development and implementation of innovative training methods are essential for enhancing microsurgical outcomes. This study aimed to evaluate the impact of a simulation training program on the clinical results of fingertip replantation surgeries.

JAMA Pediatr
January 2025
Vascular Assessment and Management Service, Department of Anaesthesia and Pain, Queensland Children's Hospital, Children's Health Queensland Hospital and Health Service, Queensland, Australia.
Importance: Pediatric peripheral intravenous catheter (PIVC) insertion can be difficult and time-consuming, frequently requiring multiple insertion attempts and often resulting in increased anxiety, distress, and treatment avoidance among children and their families. Ultrasound-guided PIVC insertion is a superior alternative to standard technique (palpation and visualization) in high-risk patients.
Objective: To compare first-time insertion success of PIVCs inserted with ultrasound guidance compared with standard technique (palpation and visualization) across all risk categories in the general pediatric hospital population.
Apixaban to Prevent Covert Infarcts After Cryptogenic Stroke in Patients With Atrial Cardiopathy: A Secondary Analysis of the ARCADIA Randomized Clinical Trial.
JAMA Neurol
January 2025
Department of Neurology, UAB Heersink School of Medicine, University of Alabama at Birmingham, Birmingham.
Importance: In the Atrial Cardiopathy and Antithrombotic Drugs in Prevention After Cryptogenic Stroke (ARCADIA) randomized clinical trial, anticoagulation did not prevent recurrent stroke among patients with a recent cryptogenic stroke and atrial cardiopathy. It is unknown whether anticoagulation prevents covert infarcts in this population.
Objective: To test the use of apixaban vs aspirin for prevention of nonlacunar covert infarcts after cryptogenic stroke in patients with atrial cardiopathy.
Pharmacy Subscription Program and Medication Refills, Days' Supply, and Out-of-Pocket Costs.
JAMA Netw Open
January 2025
Amazon Health Services, Seattle, Washington.
Importance: Medication nonadherence imposes high morbidity, mortality, and costs but is challenging to address given its multiple causes. Subscription models are increasingly used in health care to encourage healthy behaviors; in January 2023, Amazon Pharmacy launched RxPass, a subscription program offering Amazon Prime members (hereafter, company members) in 45 states access to 60 common generic medications for a flat $5 monthly fee.
Objective: To evaluate the associations of program enrollment with medication refills, days' supply, and out-of-pocket costs.
Negative Pressure Dressings to Prevent Surgical Site Infection After Emergency Laparotomy: The SUNRRISE Randomized Clinical Trial.
JAMA
January 2025
Worcestershire Royal Hospital, Worcester, United Kingdom.
Importance: Patients undergoing unplanned abdominal surgical procedures are at increased risk of surgical site infection (SSI). It is not known if incisional negative pressure wound therapy (iNPWT) can reduce SSI rates in this setting.
Objective: To evaluate the effectiveness of iNPWT in reducing the rate of SSI in adults undergoing emergency laparotomy with primary skin closure.
