Background: Recent data support both surgical-first and endovascular-first revascularization approaches for chronic limb-threatening ischemia (CLTI), but hospital-based practices are poorly described.
Objectives: This aim of this study was to characterize contemporary variations and outcomes associated with each strategy among U.S.
[18F]FDG PET/CT in Necrotizing Fasciitis: A Case Series Investigating the Clinical Utility in a Challenging and Rare Condition.

Necrotizing fasciitis is a deadly yet rare soft tissue and skin infection that is usually diagnosed clinically. At times, clinical signs may betray the underlying etiology and masquerade as cellulitis in the early course of the disease. We report four cases with clinical suspicion of necrotizing fasciitis, some after the failure of therapy for cellulitis who underwent 18-F fluorodeoxyglucose positron emission tomography-computed tomography (18-F FDG PET/CT) showing the extent of the disease, showing subclinical sites of involvement in patients with necrotizing fasciitis on baseline scan as well as its role in assessing response to treatment using 18-F FDG PET/CT.

Intracortical microelectrodes (IMEs) are essential for neural signal acquisition in neuroscience and brain-machine interface (BMI) systems, aiding patients with neurological disorders, paralysis, and amputations. However, IMEs often fail to maintain robust signal quality over time, partly due to neuroinflammation caused by vascular damage during insertion. Platelet-inspired nanoparticles (PIN), which possess injury-targeting functions, mimic the adhesion and aggregation of active platelets through conjugated collagen-binding peptides (CBP), von Willebrand Factor-binding peptides (VBP), and fibrinogen-mimetic peptides (FMP).

Int J Low Extrem Wounds

Diabetic foot Unit, San Juan de Dios Hospital, San José de Costa Rica, Costa Rica.
Diabetes-related foot osteomyelitis (DFO) can present as an acute condition with soft tissue involvement or as a non-acute form characterized by long-standing ulcers without immediate limb-threatening features. This study evaluates infection relapse and healing times after conservative surgery in non-acute DFO, with a focus on osteomyelitis localization. A retrospective cohort of 60 patients treated for forefoot DFO without soft tissue involvement or necrosis was analyzed.

The activation of progenitor cells near wound sites is a common feature of regeneration across species, but the conserved signaling mechanisms responsible for this step in whole-body regeneration are still incompletely understood. The acoel undergoes whole-body regeneration using Piwi+ pluripotent adult stem cells (neoblasts) that accumulate at amputation sites early in the regeneration process. The EGFR signaling pathway has broad roles in controlling proliferation, migration, differentiation, and cell survival across metazoans.
