atients treated for rupture have more pronounced aneurysm sac shrinkage compared with iEVAR patients during the first year after EVAR. Patients presenting with early shrinkage are less likely to encounter late complications. These parameters may be considered when tailoring surveillance protocols.

To quantify the hemodynamic consequences of thoracic endovascular aortic repair (TEVAR) by comparing the preoperative and postoperative wall shear stress (WSS) and vorticity profiles on computational fluid dynamics (CFD) simulations.

The pre- and postoperative computed tomography (CT) scans from 20 consecutive patients (median age 69 years, range 20-87) treated for different thoracic aortic pathologies (11 aneurysms, 5 false aneurysms, 3 penetrating ulcers, and 1 traumatic aortic rupture) were segmented to construct patient-specific CFD models using a meshless code. The simulations were run over the cardiac cycle, and the WSS and vorticity values measured at the proximal and distal landing zones were compared.

The CFD runs provided 4-dimensional simulations of blood flow in all patients. WSS and vorticity profiles at the proximal landing zone (located in zones 0-3 in 15 patients) varied in 18 and 20 of the cases, respectively; WSS was increased in 11 cases and the vorticity in 9. Pre- and postoperative WSS median values were 4.19 and 4.90 Pa, respectively. Vorticity median values were 40.38 and 39.17 Hz, respectively.

TEVAR induces functional alterations in the native thoracic aorta, though the prognostic significance of these changes is still unknown. CFD appears to be a valuable tool to explore aortic hemodynamics, and its application in a larger series would help define a predictive role for these hemodynamic assessments.

We evaluated the diagnostic value of plasma Macrophage inhibitory cytokine-1 (MIC-1) in distinguishing patients with nasopharyngeal carcinoma (NPC) and explored its complementary role with widely used Epstein-Barr virus (EBV) related markers, EBV capsid antigen-specific IgA (VCA-IgA) and EBV copy number.

ELISA was used to analyze the plasma MIC-1 levels in 190 NPC patients, 72 VCA-IgA-positive healthy donors (VP), and 219 normal subjects with negative VCA-IgA (VN). 10 pairs of plasma samples before and after radiotherapy were also included.

The plasma MIC-1 levels were significantly higher in NPC patients (Median 678.39 ng/mL) than those in VN and VP (310.29 and 294.59,

< 0.001). Receiver operating characteristic (ROC) curves of the MIC-1 concentrations revealed that the area under the ROC curve (AUC) was 0.790 (95% confidence interval [CI] 0.748-0.832), with a sensitivity of 63.7%, and a specificity of 85.9% respectively, for distinguishing NPC patients from the healthy donors. Similarly, between NPC and VP, ROC was 0.796 (0.738-0.853) with sensitivity of 63.7%, and specificity of 88.9%. In addition, between NPC and VN, ROC was 0.788(0.744-0.832) with sensitivity of 63.7%, and specificity of 84.9%. Further, we found that MIC-1 could complement VCA-IgA and EBV DNA markers, with a negative rate of 88.9% in VCA-IgA-positive healthy controls, and a positive rate of 59.0% in EBV DNA negative NPC patients, respectively. TBOPP mouse Also, the MIC-1 plasma concentration dropped significantly after radiotherapy (

= 0.027).

MIC-1 can complement VCA-IgA titers and EBV DNA copy number tests in NPC detection, improve identification of EBV DNA-negative NPC patients, and distinguish NPC from VCA -IgA positive healthy controls.

Using data from an observational study, we employed structural equation modeling to examine relationships among organizational and resident variables and death during transitions between LTC and ED. We identified 524 residents involved in 637 transfers from 38 LTC facilities and 2 EDs. Our model fit the data, (χ2 = 72.91, df = 56, p = .064), explaining 15% variance in resident death. Sustained shortness of breath (SOB), persistent decreased level of consciousness (LOC) and high triage acuity at ED presentation were direct and significant predictors of death. The estimated model can be used as a framework for future research. Standardized reporting of SOB and changes in LOC, scoring of resident acuity in LTC and timely palliative care consultation for families in the ED, when they are present, warrant further investigation.Infections with Listeria monocytogenes (LM) are very uncommon and severe especially in immunocompromised people. We report a continuous cycling peritoneal dialysis (CCPD) patient who presented initially disseminated listeriosis with peritonitis. He was successfully treated with intraperitoneal and intravenous ampicillin but died unfortunately from a cardiorespiratory arrest due to food inhalation. It is the 20th case of such peritonitis mentioned among PD patients and the first reported in Belgium. This case illustrates the importance of a systematic approach to get quick diagnosis and effective antibiotic readjustment. Empiric therapy is not effective on Listeria which is naturally resistant to cephalosporins and poorly sensitive to vancomycin. Ampicillin is the first-line antibiotic. In case of penicillin allergy, trimethoprim-sulfamethoxazole or erythromycin can be used successfully. Identification of LM serotype has a prognostic value. PD educative programmes should recommend to avoid unpasteurized dairy products to prevent listeriosis.Highly pathogenic influenza A viruses (IAVs) cause substantial damage to the poultry industry. A simple and quick testing method is required for strict control of this infectious agent. The fluorescence polarization immunoassay (FPIA) is a rapid test based on antigen-antibody binding, which can detect antigen-specific antibody in the infected animal samples within a few minutes. FPIA is a one-step reaction assay that does not require a secondary antibody and complicated steps. We evaluated the usefulness of FPIA for the detection of anti-IAV antibodies, including those against internal proteins and H5 subtype HA, in sera. In the FPIA using fluorescent peptides of internal NP and M1 proteins, millipolarization units (MPUs), which increase depending on the amount of antibody, were higher in antibody-positive sera than in antibody-negative sera. Moreover, in FPIA using fluorescent recombinant H5 subtype HA proteins, anti-H5 serum gave the highest MPUs among the antisera raised in goats against individual H1-H15 subtype IAVs.
