sults can be expected if the injury is diagnosed without delay followed by adequate therapy. Misdiagnosis of ulnar condyle fractures can be associated with the development of nonunions and functional restrictions as well as, after operative therapy, trochlear necrosis. Children up to the age of 6 in particular are at risk of misdiagnosis due to faulty assessment of the cartilaginous trochlea.

Its anti-inflammatory and cardioprotective properties are increasingly considered to have beneficial effects on the progression of cardiomyopathy associated with Chagas disease, caused by Trypanosoma cruzi. However, the Cur therapeutic limitation is its bioavailability and new Cur nanomedicine formulations are developed to overcome this obstacle. In this research, we provide evidence showing that oral therapy with a suboptimal dose of the standard parasiticidal drug benznidazole (BZ) in combination with Cur-loaded nanoparticles is capable of reducing myocardial parasite load, cardiac hypertrophy, inflammation and fibrosis in mice with long-term infection by T. cruzi. Treatment with BZ plus Cur was highly effective in downregulating myocardial expression of proinflammatory cytokines/chemokines (IL-1β, TNF-α, IL-6, CCL5), and the level/activity of matrix metalloproteinases (MMP-2, MMP-9) and inducible enzymes (cyclooxygenase, nitric oxide synthase) implicated in leukocyte recruitment and cardiac remodeling. Oral administration of a Cur-based nanoformulation displays potential as a complementary strategy to the conventional BZ chemotherapy in the treatment of chronic Chagas heart disease.Unveiling the molecular mechanisms underlying tissue regeneration provides new opportunities to develop treatments for diabetic ulcers and other chronic skin lesions. Here, we show that Ccl2 secretion by epidermal keratinocytes is directly orchestrated by Nrf2, a prominent transcriptional regulator of tissue regeneration that is activated early after cutaneous injury. Through a unique feedback mechanism, we find that Ccl2 from epidermal keratinocytes not only drives chemotaxis of macrophages into the wound but also triggers macrophage expression of EGF, which in turn activates basal epidermal keratinocyte proliferation. Notably, we find dysfunctional activation of Nrf2 in epidermal keratinocytes of diabetic mice after wounding, which partly explains regenerative impairments associated with diabetes. These findings provide mechanistic insight into the critical relationship between keratinocyte and macrophage signaling during tissue repair, providing the basis for continued investigation of the therapeutic value of Nrf2.Given the growing rate of revision total knee arthroplasties (TKAs), it is important to understand the potential risk factors associated with postoperative complications. The aim of this study was to determine the role of operative time in postoperative complications in revision TKA. A retrospective cohort study was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database. Patients who had undergone revision TKA between 2007 and 2016 were identified and analyzed based on operative time. The effect of operative time on postoperative complications was examined using multinomial multivariate analysis. A total of 14,769 revision TKA patients were included. On adjusted multivariate analysis, each additional 15 minutes of operative time increased the likelihood of wound
