BACKGROUND Hepatocellular carcinoma (HCC) is an aggressive malignant tumor with poor prognosis that is characterized by high rates of postoperative recurrence and mortality. Understanding the molecular mechanism of this malignancy is of great significance for the development of new and effective strategies for the treatment of hepatocellular carcinoma. Thyroid hormone receptor-interacting protein 6 (TRIP6), also known as zyxin-related protein-1 or ZRP-1, is an adaptor protein that belongs to the zyxin family of LIM proteins. Recent studies showed that TRIP6 is involved in carcinogenesis. But the functional role of TRIP6 in HCC has not been reported to date. METHODS TRIP6 expression level in HCC cell lines and normal cell line was measured by qPCR. The roles of TRIP6 on HCC cell proliferation, colony formation, and invasion were examined by MTT assay, colony formation assay, and transwell invasion assay, respectively. The effect of TRIP6 on the overall survival of HCC patients was further analyzed. ChIP assay and western blot were performed to validate whether FOXC1 was involved in the regulation of TRIP6 expression. RESULTS Western blot and immunohistochemical analyses showed that TRIP6 expression was up-regulated in HCC tissues compared with adjacent non-tumor tissues. Kaplan-Meier survival analysis indicated that upregulation of TRIP6 was dramatically associated with poor overall survival. TRIP6 knockdown significantly inhibited cell migration, invasion, and proliferation, and its effect on cell proliferation was mediated by the modulation of cell cycle progression. FOXC1 also played a vital role in TRIP6 regulation. TRIP6 mediated the FOXC1-regulated proliferation, invasion, and migration in vitro and tumor growth in vivo. CONCLUSIONS These results suggest that TRIP6 may contribute to the invasiveness and metastasis of HCC cells, and provide new insight into the crucial role of TRIP6 in tumorigenesis and cancer progression. BACKGROUND The purpose of this study is to investigate the incidence and timing of postoperative, symptomatic pulmonary embolism (PE) in patients receiving nonwarfarin treatment following primary total joint arthroplasty (TJA), to clarify the appropriate duration of postoperative VTE prophylaxis. METHODS We retrospectively reviewed the medical records of 11,148 patients who underwent primary TJA, including total knee arthroplasty and total hip arthroplasty at our institution between January 2012 and March 2019. The median postoperative day of diagnosis of symptomatic PE and the interquartile range for day of diagnosis were determined. Multivariate Cox proportional hazards modeling was used to test the difference of timing for PE based on demographics and comorbidities. RESULTS The overall 90-day rate of symptomatic PE was 0.71%. The median day of diagnosis for symptomatic PE was 3 days postoperatively (interquartile range, 2-7 days). Factors showed statistical significance on multivariate analysis in association with earlier timing of PE occurrence in patients with atrial fibrillation, diabetes mellitus, coronary heart disease, and history of stroke. CONCLUSION The vast majority of symptomatic PE occurs in the early postoperative period after TJA, and atrial fibrillation, diabetes mellitus, coronary heart disease, and history of stroke were independent factors affecting the timing of symptomatic PE. BACKGROUND The direct anterior approach (DAA) is increasingly used for total hip arthroplasty (THA). Although the DAA can reduce pain, recovery time, and dislocations in nondysplastic hips, few studies report its results in patients with severe dysplasia. We aimed to evaluate outcomes of primary THA through the DAA with cup placement at the true acetabulum in hips with severe dysplasia. METHODS We retrospectively evaluated 23 consecutive patients (29 hips) who underwent THA by DAA for osteoarthritis secondary to Crowe III-IV dysplasia. Surgical procedures were performed on a traction table, and the acetabular cup was placed in the true acetabulum. Patients were assessed clinically (complications, modified Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, Oxford Hip Score) and radiographically (radiolucencies, subsidence, leg length discrepancies, cup inclination, and cup coverage) at a minimum of 2 years. RESULTS One patient (2 hips) died with original implants (at 13 and 14 years), 3 patients (3 hips) were revised due to wear-induced loosening (at 14, 16, and 18 years), and there were no dislocations or infections. The remaining 19 patients (24 hips) were assessed at 8.4 ± 4.7 years (range 2-20); 2 patients (2 hips) had complications that required reoperation without implant removal. The modified Harris Hip Score improved from 32 ± 9 to 94 ± 7, Western Ontario and McMaster Universities Osteoarthritis Index from 46 ± 18 to 90 ± 7, and Oxford Hip Score was 56 ± 4. Patients were very satisfied (90%) or satisfied (10%). Limb length discrepancy was 2.5 ± 9.0 mm. CONCLUSION THA through the DAA with cup placement at the true acetabulum provides satisfactory mid to long-term clinical and radiographic outcomes compared to other approaches for hips with severe dysplasia. LEVEL OF EVIDENCE Level IV, retrospective cohort study. Most sialic acid-binding immunoglobulin-like lectins (Siglecs) suppress immune cell function but are expressed at low levels on human T cells. We found that soluble CD52 inhibited T cell signalling by ligating Siglec-10, but the presence of Siglec-10 on human T cells has been questioned. To address this concern, we examined the expression of Siglec-10 at the RNA and protein level in human CD4+ T cells. Analysis by RNAseq, qPCR and flow cytometry demonstrated that, in contrast to other Siglecs, after activation of CD4+ T cells Siglec-10 was selectively upregulated in a subset of cells also high for CD52 expression. This observation is consistent with a homeostatic role for Siglec-10 in human CD4+ T cells. STUDY OBJECTIVE We determine the accuracy of high-sensitivity cardiac troponin I (hs-cTnI), European-derived, rapid, acute myocardial infarction, rule-out/rule-in algorithms applied to a US emergency department (ED) population. METHODS Adults presenting to the ED with suspected acute myocardial infarction were included. Plasma samples collected at baseline and between 40 and 90 minutes and 2 and 3 hours later were analyzed in core laboratories using the Siemens Healthineers hs-cTnI assays. https://www.selleckchem.com/products/otx015.html Acute myocardial infarction diagnosis was independently adjudicated. The sensitivity, specificity, and negative and positive predictive values for rapid acute myocardial infarction rule-out/rule-in using European algorithms and 30-day outcomes are reported. RESULTS From 29 US medical centers, 2,113 subjects had complete data for the 0/1-hour algorithm analyses. With the Siemens Atellica Immunoassay hs-cTnI values, 1,065 patients (50.4%) were ruled out, with a negative predictive value of 99.7% and sensitivity of 98.7% (95% confidence interval 99.
