Clinical volume has been associated with rate of complications and mortality for various conditions and procedures. We aim to analyze the relationship between annual hospital burn admission, patient safety indicators (PSI), line infections, and inpatient mortality. We hypothesize that high facility volume will correlate with better outcomes. ⋯ There was a significant association between higher hospital volume and decreased likelihood of patient safety indicators and mortality. There was no observed relationship with line infections. These findings could inform future verification policies of US burn centers.

In burn patients, vitamin D has been studied primarily in the pediatric population and focused mainly on the correlation with bone marker measurements and incidence of fractures. There is an association between vitamin D deficiency and the development of sepsis in non-burn critically-ill patients. However, there is limited data on vitamin D concentrations and clinical outcomes in burn patients, such as sepsis. The objective of this study is to evaluate the impact of vitamin D concentrations on the incidence of sepsis in adult burn patients. ⋯ Patients with adequate vitamin D concentrations on admission had a reduction in the incidence of sepsis as compared to patients with insufficient vitamin D concentrations. Insufficient vitamin D concentrations may contribute to other worsened clinical outcomes in burn patients. Our findings set the stage for future, multicenter studies to determine the role of vitamin D supplementation in burn patients.

Type 2 diabetes mellitus (T2DM) is an important reason to cause chronic wound healing or even amputation to patients. A common characteristic of T2DM is the presence of hyperglycemia. Autophagy, a cellular pathway which related to protein and organelle degradation, is relevant to many types of cellular homeostasis change and human diseases including diabetes. ⋯ Then we examined the expression levels of TNF-α, TLR-4 and p62 to assess inflammatory statement. High glucose induced a significant increasement in the expression of both autophagic markers and inflammatory markers and these elevated protein levels were reversed after the use of wnt7a. Therefore, these results showed that wnt7a regulates overwhelmed autophagy and inflammation promoted under high glucose condition.

Electrospinning process has gained importance in the production of wound dressings in recent years. The wound dressings prepared by electrospinning method provide many advantages over conventional wound dressings. The aim of this study was to assess the histological, biochemical, and immunohistochemical evaluation of collagen/doxycycline loaded nanofiber wound dressing in both acute and chronic wound healing. ⋯ According to the biochemical analyses, it was concluded that the nanofiber wound dressing helps to increase antioxidant capacity and decrease lipid peroxidation. Immunohistochemical studies showed that nanofiber wound dressing enhanced angiogenesis and shortened the inflammatory phase. It was concluded that an effective and safe prototype nanofiber wound dressing, which has similar wound healing effect to the commercial product, has been developed to be used in acute or chronic wound treatment.
