1 ± 1.5 vs. - 18.7 ± 1.3, p  less then  0.001), (GLS-mid-myocard; - 16.0 ± 2.0 vs. - 18.0 ± 2.0, p  less then  0.001), (GLS-epicard; - 17.0 ± 1.7 vs. - 18.01 ± 1.94, p = 0.004)). GLS-endocard levels were significantly and positively correlated with HOMA-IR levels (r = 0.643, p  less then  0.001). HOMA-IR and age were found to be independent factors in detecting a decrease in GLS-endocard level in regression analysis. In conclusion, our data reveal that IR (+) patients had significantly lower strain values compared to IR (-) group. Besides, we presented that the HOMA-IR value was an independent predictor of subclinical left ventricular dysfunction.Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder leading to progressive skeletal and cardiac myopathy. Elevated myocardial T1 values correlate with fibrosis in most disease processes, but DMD skeletal and cardiac histopathology is defined by fibrofatty replacement that may result in a decrease in T1 values, due to the low T1 of fat. The study goal was to assess myocardial T1 values in DMD patients with and without late gadolinium enhancement (LGE). A retrospective analysis was performed on all patients with DMD referred for CMR at our institution from 7/5/2017 to 10/24/2018. T1 measurements were performed using breath-held modified Look Locker inversion recovery (MOLLI) sequences at the basal and mid-ventricular levels. The cohort was separated into patients without the presence of LGE (LGE-) and patients with current or previous LGE (LGE+). A total of 207 CMR studies were analyzed. The LGE- group comprised 88 patients while 119 patients were in the LGE+ group. The LGE+ group was older, had le is not a simple linear relationship between increasing T1 values and advancing disease progression reported in most other cardiomyopathies.Two Gram-stain-negative, facultatively anaerobic bacteria, designated ZY170218T and ZY180512, were isolated from lungs of dead sheep with hemorrhagic pneumonia in Yunnan Province, China and their taxonomic positions were studied by a polyphasic approach. The two isolates grew optimally at 37 °C, pH 9.0 and 1.0% NaCl (w/v), and showed identical 16S rRNA, recN and rpoB gene sequences. Phylogenetic analysis based on 16S rRNA gene sequence showed that the two strains fell within the cluster of species in the genus Mannheimia and formed a separated lineage with comparatively low similarity to the closest related species M. granulomatis (96.5%). Phylogenetic analysis based on rpoB gene indicated that the strains formed a monophyletic evolutionary lineage, with low sequence similarity ≤ 89.0% to the species of the genus Mannheimia. The genomic OrthoANI values between strain ZY170218T and M. granulomatis and M. haemolytica were 80.4% and 83.1%, respectively. Thymidine price The genomic G + C content of strain ZY170218T was 39.1 mol%. The predominant fatty acids (> 5%) of the two strains were C160, C140, C181ω7c, summed feature 3 (C161 ω7c and/ or C161ω6c) and summed feature 2 (C140 3OH/ C161 Iso). The major polar lipids of strain ZY170218T were phosphatidylglycerol, phosphatidylcholine, monogalactosyldiacylglycerol, bis(monoacylglycero)phosphate and diacylglycerols. The sole respiratory quinone of the two strains was CoQ-7. On the basis of phylogenetic, phenotypic and chemotaxonomic features, strain ZY170218T and ZY180512 clearly represents a novel species of the genus Mannheimia, for which the name Mannheimia ovis sp. nov. is proposed. The type strain is ZY170218T (= CGMCC 1.13620 T = KCTC 15731 T).Magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18FDG 18F-FDG PET-CT) are standard procedures for staging multiple myeloma (MM). Diffusion-weighted sequences applied to whole-body MRI (WB-DWI) improve its sensitivity. We compared the number of MM bone focal lesions (FLs) detected by 18F-FDG PET-CT and WB-DWI and evaluated the diagnostic performance of 18F-FDG PET-CT for diffuse infiltration. Thirty newly diagnosed MM patients prospectively underwent 18F-FDG PET-CT and WB-DWI. The criteria for skeletal region positivity were ≥ 1 focal bone lesions (FLs) and/or diffuse disease. MRI with the MY-RADS criteria was used as a reference standard for the diagnosis of diffuse infiltration. 18F-FDG PET-CT and WB-DWI were both interpreted as positive in 28/30 patients with an agreement of 1.00 (95% CI 0.77-1.00) between the two methods. The mean numbers of FLs were 16.7 detected by 18F-FDG PET-CT and 23.9 detected by WB-DWI (P = 0.028). WB-DWI detected more FLs in the skull (P = 0.001) and spine (P = 0.006). Agreement assessed using the prevalence and bias-corrected kappa index was moderate (0.40-0.60) for the spine, sternum-ribs and upper limbs and substantial (0.60-0.80) for the pelvis and lower limbs. As regards the diagnosis of diffuse bone marrow infiltration, the sensitivity, specificity and accuracy of 18F-FDG PET-CT were 0.75, 0.79 and 0.77, respectively. Although WB-DWI detected more FLs than did 18F-FDG PET-CT, there was no difference in the detection of bone disease on a per-patient basis. 18F-FDG PET-CT showed high performance, including for evaluation of diffuse infiltration.

The AJCC 8th edition TNM classification for lung cancer was released in 2017. This edition has made major changes in many tumor descriptors including sites of metastasis. The new staging system has been a subject of multiple validation studies, of which many have had mixed results. The present study is designed to critically evaluate the results of these external validation studies.

A metaanalysis of these external validation studies was performed to critically evaluate the new staging system. Out of 12 studies, 8 were found to fulfill the eligibility criteria, with 654,185 patients being included in the analysis. Hazard ratios (HRs) and associated 95% confidence intervals (CI) extracted from these studies were utilized for analysis. The primary outcomes were survival discrimination and prognostic ability of the 8th edition compared with the 7th edition.

The HRs for the 8th edition staging system were 1.41 in IB, 1.64 in IIA, 1.24 in IIB, 1.95 in IIIA, 3.96 in IIIB, and 4.82 in IIIC compared with IA. The new edition fared better than the 7th edition in survival discrimination in all but stage IIA and IIB.
