Penetrating aerodigestive injuries and the role of computed tomography esophagography.

Background: Penetrating neck injuries can be fatal if not quickly identified; however, operative intervention is not always necessary. Prompt evaluation with imaging studies aids in identifying patients who need intervention.

Methods: A retrospective, single-center study of patients with PNI from 2017 to 2022 was performed.

Extended Prophylactic Antibiotics in Penetrating Neck Aerodigestive Injuries are Not Associated with Improved Outcomes.

Literature currently supports the limited use of prophylactic antibiotics within the trauma population. However, data supporting limited (≤24 h) or extended (>24 h) use in penetrating aerodigestive neck injuries is lacking. We sought to describe the role of prophylactic antibiotics in this population and hypothesized there was no reduction in complications for patients on extended prophylactic antibiotics.

Diverse bone-calcium isotope compositions in Neandertals suggest different dietary strategies.

Zooarcheological and geochemical evidence suggests Neanderthals were top predators, but their adherence to a strictly carnivorous diet has been questioned. Recent studies have demonstrated the potential of calcium-stable isotopes to evaluate trophic and ecological relationships. Here, we measure the δCa values in bone samples from Mousterian contexts at Grotte du Bison (Marine Isotope Stage 3, Yonne, France) and Regourdou (Marine Isotope Stage 5, Dordogne, France) in two new Neanderthal individuals, associated fauna, and living local plants.

Directed work-up of select penetrating neck injuries is safe: Hard signs continue to soften.

Introduction: Management of penetrating neck injuries (PNIs) has evolved over time, more frequently relying on increased utilization of diagnostic imaging studies. Directed work-up with computed tomography imaging has resulted in increased use of angiography and decreased operative interventions. We sought to evaluate management strategies after directed work-up, hypothesizing increased use of non-operative therapeutic interventions and lower mortality after directed work-up.

Sex estimation of the adult Neandertal Regourdou 1 (Montignac, France): Implications for sexing human fossil remains.

Sex is a biological trait fundamental to the study of hominin fossils. Among the many questions that can be addressed are those related to taxonomy, biological variability, sexual dimorphism, paleoobstetrics, funerary selection, and paleodemography. While new methodologies such as paleogenomics or paleoproteomics can be used to determine sex, they have not been systematically applied to Pleistocene human remains due to their destructive nature.
