Links between trauma center volumes and outcomes have been inconsistent in previous studies. This study examines the role of institutional trauma volume parameters in geriatric motor vehicle collision (MVC) survival. ⋯ There may be a risk-adjusted survival advantage for geriatric MVC patients treated at trauma centers with relatively higher volumes of geriatric MVC trauma and lower volumes of young adult non-MVC trauma. These results support consideration of age in trauma center transfer criteria.

Despite substantial improvements in trauma care, severe injuries often result in significant long-term consequences for otherwise young, healthy individuals. Providing patient-centered care and extensive psychosocial support services is difficult for trauma centers. ⋯ The Trauma Survivors Network provides a critical component of trauma care that can be adapted for local needs throughout the country. Implementation of these services is a necessary step in the development of comprehensive trauma systems that not only save lives but also reduce long-term disability among survivors.

Nonoperative management for selective patients with solid organ injuries from blunt trauma has gained wide acceptance. However, for trauma surgeons, it is often difficult to estimate a patient's circulatory volume. Some authors have proposed that the presence of a collapsed inferior vena cava (IVC) on computed tomography (CT) scan correlates with inadequate circulatory volume. Our aim was to verify whether CT evidence of a flat IVC (FI) is an indicator of hypovolemia in blunt trauma patients with solid organ injuries. ⋯ CT evidence of FI is a good indicator of hypovolemia and an accurate predictor for prognosis in trauma patients with blunt solid organ injuries.

The authors investigated poly(lactide-co-glycolide) (PLGA) capsule and collagen composite system for antibiotics and bone cells delivery to treat infected bone defects. Poly(lactide-co-glycolide) was mixed with vancomycin and hot compressing molded to form an antibiotic capsule. Rabbit mesenchymal stem cells (MSCs) were entrapped in collagen gel phase and dispersed throughout the void volume of capsule. ⋯ Sample inhibition zone was 9 mm to 24 mm, and the relative activity was 11.8% to 100%. Implanted PKH 26-labeled MSCs were identified in the newly formed bony trabeculae in specimens at 2 and 4 months after implantation. The results offer a potential approach to meet clinical requirements in the treatment of infected bone defects.
