Background: Vascularized fibula grafts (VFGs) have become one of the most preferred grafts for the reconstruction of bone defects. However, despite the many advantages over other graft options, recipient and donor site morbidities are also common. Donor site morbidity has been reported at rates ranging from 5% to 67%. The aim of this study was to present a single-center series examining the clinical, functional, and radiologic aspects of donor site morbidity following VFG harvesting.
Methods: The study included 69 patients who underwent biological reconstruction with VFG for bone tumors, avascular necrosis of the femoral head, or bone defects after trauma. Patients were evaluated functionally, clinically, and radiologically for donor site morbidity.
Results: Donor site morbidity was observed in 33 of 69 patients (48%). The most complications were sensation deficits around the feet and ankles (20 of 69; 29%). Knee laxity was more common in patients who underwent osteoarticular fibular resection ( = .006).
Conclusion: We found VFG to be an effective method for the reconstruction of large bone defects, but associated with a relatively high rate of complications. Complications requiring surgical intervention were rare and the majority of patients did not have long-term functional limitations.
Level Of Evidence: Level IV, retrospective case series.

The increasing global prevalence of Alzheimer's disease necessitates the development of novel therapeutic approaches. Neurodegenerative diseases are associated with increased oxidative stress and levels of cholinesterase enzymes. Hence, the development of cholinesterase inhibitors and antioxidants may provide neuroprotective effects.

COVID-19 has been emerging as the most influential illness which has caused great costs to the heath of population and social economy. Sivelestat sodium (SS) is indicated as an effective cure for lung dysfunction, a characteristic symptom of COVID-19 infection, but its pharmacological target is still unclear. Therefore, a deep understanding of the pathological progression and molecular alteration is an urgent issue for settling the diagnosis and therapy problems of COVID-19.

Objective: This retrospective cohort study aims to compare donor site morbidity of three commonly used upper extremity flaps used in head and neck reconstructive surgery: scapular tip free flap (STFF), radial forearm free flap (RFFF), and pectoralis major pedicled flap (PMPF).
Methods: The billing database of an urban, academic, tertiary otolaryngology practice was queried to identify patients who underwent STFF, RFFF, and PMPF from 2020 to 2023. The primary outcome was identification of donor site pain and need for physical therapy (PT) referral after undergoing reconstruction.

Background: Acetyl phosphate (AcP) is a microbial intermediate involved in the central bacterial metabolism. In bacteria, it also functions as a donor of acetyl and phosphoryl groups in the nonenzymatic protein acetylation and signal transduction. In host, AcP was detected as an intermediate of the pyruvate dehydrogenase complex, and its appearance in the blood was considered as an indication of mitochondrial breakdown.
