The transport and vertical distribution of microplastics in the Mekong River, SE Asia.

Rivers are primary vectors of plastic debris to oceans, but sources, transport mechanisms, and fate of fluvial microplastics (<5 mm) remain poorly understood, impeding accurate predictions of microplastic flux, ecological risk and socio-economic impacts. We report on microplastic concentrations, characteristics and dynamics in the Mekong River, one of the world's largest and polluting rivers, in Cambodia and Vietnam. Sampling throughout the water column at multiple localities detected an average of 24 microplastics m (0.

Postfasciotomy Classification System for Acute Compartment Syndrome of the Leg.

Objective: Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication.

EXOGEN Mitigates Risk of Fifth Metatarsal Fracture Nonunion: Results of a Novel Real-World Clinical Study.

Category:: Midfoot/Forefoot

Introduction/purpose:: Fifth metatarsal fractures are the most commonly fractured metatarsal in adults and are associated with high rates of nonunion. This study compared the 9-month incidence of nonunion in fifth metatarsal fracture patients using EXOGEN (Bioventus LLC), low-intensity pulsed ultrasound, versus a control cohort of patients receiving standard of care.

Methods:: Adults (21-80 years) prescribed EXOGEN for any acute or delayed fifth metatarsal fracture and initiated treatment within 91 days of the fracture were enrolled via prescription record abstraction and direct-to-patient outreach.

Defining Incidence of Acute Compartment Syndrome in the Research Setting: A Proposed Method From the PACS Study.

Objective: To compare the retrospective decision of an expert panel who assessed likelihood of acute compartment syndrome (ACS) in a patient with a high-risk tibia fracture with decision to perform fasciotomy.

Design: Prospective observational study.

Setting: Seven Level 1 trauma centers.

Factors influencing management of bilateral femur fractures: A multicenter retrospective cohort of early versus delayed definitive Fixation.

Introduction: The purpose of our study was to evaluate the factors that influence the timing of definitive fixation in the management of bilateral femoral shaft fractures and the outcomes for patients with these injuries.

Methods: Patients with bilateral femur fractures treated between 1998 to 2019 at ten level-1 trauma centers were retrospectively reviewed. Patients were grouped into early or delayed fixation, which was defined as definitive fixation of both femurs within or greater than 24 hours from injury, respectively.
