SARS-Co-V-2 positive status is associated with a more seriously injured population of trauma patients but not independently associated with worse outcomes of trauma care.

Background: SARS-CoV-2 positive status has been considered a predominantly incidental finding among trauma patients. We sought to examine whether concurrent infection is associated with worse outcomes in a contemporary cohort of injured patients during the COVID-19 pandemic.

Methods: Retrospective cohort analysis of a level I trauma center's institutional registry from May 1, 2020 through June 30, 2021.

National patterns of injury and outcomes of gunshot wounds to the penis: A Trauma Quality Programs retrospective cohort analysis.

Aim: Gunshot wounds (GSW) to the penis represent a rare type of traumatic injury in the civilian United States population. Although small, single-center studies have reported results of care for these types of injured patients, no national analyses have examined this group.

Methods: A cohort of patients with GSW to the penis was identified using the 2017 American College of Surgeons Trauma Quality Programs database, a comprehensive national database of 753 accredited trauma centers.

Pregnant trauma patients may be at increased risk of mortality compared to nonpregnant women of reproductive age: trends and outcomes over 10 years at a level I trauma center.

Background: Pregnancy has been identified as a risk factor for poor outcomes after traumatic injury, but prior outcome analyses are conflicting and dated. We sought to examine outcomes in a contemporary cohort.

Methods: Retrospective cohort analysis at a level I trauma center's institutional registry from 2009 to 2018, with comparison to population-level demographic trends in women of reproductive age and pregnancy prevalence.

No Reduction in Surgical Site Infection Obtained with Post-Operative Antibiotics in Facial Fractures, Regardless of Duration or Anatomic Location: A Systematic Review and Meta-Analysis.

We performed a systematic review of the literature on antibiotic prophylaxis practices in open reduction, and internal fixation of, facial fracture(s) (ORIFfx). We hypothesized that prolonged antibiotic prophylaxis (PAP) would not decrease the rate of surgical site infections (SSIs). We performed a systematic review of four databases: PubMed, CENTRAL, EMBase, and Web of Science, from inception through January 15, 2017.

Dissociation of two-dimensional excitons in monolayer WSe.

Two-dimensional (2D) semiconducting materials are promising building blocks for optoelectronic applications, many of which require efficient dissociation of excitons into free electrons and holes. However, the strongly bound excitons arising from the enhanced Coulomb interaction in these monolayers suppresses the creation of free carriers. Here, we identify the main exciton dissociation mechanism through time and spectrally resolved photocurrent measurements in a monolayer WSe p-n junction.
