Comparative Study
Comparison of two different models of sepsis induced by cecal ligation and puncture in rats.
The present study was designed to explore the difference between two rat models of sepsis and to establish a more stable rat model. ⋯ These results suggested that the cecal ligation combined with puncture drainage model of sepsis is more stable than that of the simple cecal ligation and puncture model of sepsis in the rat, which resolved the problem of puncture wrapped in the traditional CLP model of sepsis in rat.

Comparative Study
Scholarly activity in academic plastic surgery: the gender difference.
The number of women in medicine has grown rapidly in recent years. Women constitute over 50% of medical school graduates and hold 38% of faculty positions at United States medical schools. Despite this, gender disparities remain prevalent in most surgical subspecialties, including plastic surgery. The purpose of this study was to analyze gender authorship trends. ⋯ This study identifies significant gender disparities in scholarly productivity among plastic surgeons in academia. Future efforts should focus on improving gender equality and eliminating barriers to academic development.

The three known systems for evaluation of patients with rib fractures are rib fracture score (RFS), chest trauma score (CTS), and RibScore (RS). The aim was to establish critical values for these systems in different patient populations. ⋯ Physicians should choose score to match specific population and collected variables. RFS is simple but sensitive in elderly population. CTS is recommended for geriatric patients as it predicts PN the best. RS is recommended for assessment of severely injured patients with high ISS.

Adipose-derived stem cells (ASCs) are capable of secreting regenerative growth factors and replacing multiple tissue types. Although current literature suggests that ASCs accelerate wound healing and reduce scarring, the dose-response relationship has not been adequately investigated in large animals. We sought to establish a porcine model to optimize dose and delivery. ⋯ Doses up to 3.0 × 106 cells/cm2 were well-tolerated. High-dose ASCs accelerate wound contraction, enhance neovascularization, and may improve scar quality in excisional wounds healing by secondary intention. Doses greater than those previously used may be necessary to achieve desired effects.
