Epidemiology and treatment of pediatric tibial fractures in Sweden: a nationwide population-based study on 5828 fractures from the Swedish Fracture Register.
Pediatric tibial fractures have been described internationally as mainly caused by fall during leisure activities and organized sports and showing a higher incidence in boys. Still, most studies are single center studies or have a small sample size. This study aimed to analyze sex and age distribution, seasonal variation, injury mechanisms and treatment of pediatric tibial fractures based on the nationwide Swedish Fracture Register (SFR). ⋯ Injury mechanism differs between age groups; play/free time injuries are common in younger children compared with sport activities in older children. Most patients are treated non-surgically. Open fractures are rare. Information on injury patterns is useful working preventively, for example safety work in playgrounds.

miR-181c, a potential mediator for acute kidney injury in a burn rat model with following sepsis.
The miRNA profile is changed after burn or sepsis and is involved in regulating inflammatory reactions. However, the function and molecular mechanism of miRNAs in regulating burn sepsis-induced acute kidney injury (AKI) are still unclear. ⋯ Our results demonstrated that miR-181c could suppress TLR4 expression, reduce inflammatory factor and chemokine secretion, mitigate inflammatory cell infiltration into the kidney and downregulate KIM-1 expression, which might ultimately attenuate burn sepsis-induced AKI.

Hemorrhagic shock and tissue injury provoke distinct components of trauma-induced coagulopathy in a swine model.
Tissue injury (TI) and hemorrhagic shock (HS) are the major contributors to trauma-induced coagulopathy (TIC). However, the individual contributions of these insults are difficult to discern clinically because they typically coexist. TI has been reported to release procoagulants, while HS has been associated with bleeding. We developed a large animal model to isolate TI and HS and characterize their individual mechanistic pathways. We hypothesized that while TI and HS are both drivers of TIC, they provoke different pathways; specifically, TI reduces time to clotting, whereas, HS decreases clot strength stimulates hyperfibrinolysis. ⋯ Isolated injury in animal models can help elucidate the mechanistic pathways leading to TIC. Our results suggest that isolated TI leads to early histone release and a hypercoagulable state, with suppressed fibrinolysis. In contrast, HS promotes poor clot strength and hyperfibrinolysis resulting in hypocoagulability.

Self-efficacy and application of skills in the workplace after multidisciplinary trauma masterclass participation: a mixed methods survey and interview study.
The most complex injuries are usually least often encountered by trauma team members, limiting learning opportunities at work. Identifying teaching formats that enhance trauma skills can guide future curricula. This study evaluates self-assessed technical and nontechnical trauma skills and their integration into novel work situations for multidisciplinary trauma masterclass participants. ⋯ Course participants' self-assessed work performance mostly benefited from greater self-efficacy and nontechnical skills. Future trauma curricula should consider aligning the teaching strategies accordingly.
