1Are hyoliths Palaeozoic lophophorates?显示文摘The phylogenetic position of hyoliths has long been unsettled,with recent discoveries of a tentaculate feeding apparatus('lophophore')and fleshy apical extensions from the shell('pedicle')suggesting a lophophorate affinity.Here,we describe the first soft parts associated with the feeding apparatus of an orthothecid hyolith,Triplicatella opimus from the Chengjiang biota of South China.The tuft-like arrangement of the tentacles of T.opimus differs from that of hyolithids:suggesting they collected food directly from the substrate.A reassessment of the feeding organ in hyolithids indicates that it does not represent a lophophore and our analysis of the apical structures associated with some orthothecids show that these represent crushed portions of the shell and are not comparable to the brachiopod pedicle.The new information suggests that hyoliths are more likely to be basal members of the lophotrochozoans rather than lophophorates closely linked with the Phylum Brachiopoda.Fan Liu Christian B Skovsted Timothy P Topper Zhifei Zhang Degan Shu 2020National Science Review2020,7,2:5
2Hepatic encephalopathy before and neurological complications after liver transplantation have no impact on the employment status 1 year after transplantation显示文摘AIM To investigate the impact of hepatic encephalopathybefore orthotopic liver transplantation(OLT) and neurological complications after OLT on employment after OLT.METHODS One hundred and fourteen patients with chronic liver disease aged 18-60 years underwent neurological examination to identify neurological complications, neuropsychological tests comprising the PSE-SyndromeTest yielding the psychometric hepatic encephalopathy score, the critical flicker frequency and the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS), completed a questionnaire concerning their occupation and filled in the short form 36(SF-36) to assess health-related quality of life before OLT and 12 mo after OLT, if possible. Sixty-eight(59.6%) patients were recruited before OLT, while on the waiting list for OLT at Hannover Medical School [age: 48.7 ± 10.2 years, 45(66.2%) male], and 46(40.4%) patients were included directly after OLT. RESULTS Before OLT 43.0% of the patients were employed. The patients not employed before OLT were more often non-academics(employed: Academic/non-academic 16(34.0%)/31 vs not employed 10(17.6%)/52, P = 0.04), had more frequently a history of hepatic encephalopathy(HE)(yes/no; employed 15(30.6%)/34 vs not employed 32(49.2%)/33, P = 0.05) and achieved worse results in psychometric tests(RBANS sum score mean ± SD employed 472.1 ± 44.5 vs not employed 443.1 ± 56.7, P = 0.04) than those employed. Ten patients(18.2%), who were not employed before OLT, resumed work afterwards. The patients employed after OLT were younger [age median(range, min-max) employed 47(42, 18-60) vs not employed 50(31, 29-60), P = 0.01], achieved better results in the psychometric tests(RBANS sum score mean ± SD employed 490.7 ± 48.2 vs not employed 461.0 ± 54.5, P = 0.02) and had a higher health-related quality of life(SF 36 sum score mean ± SD employed 627.0 ± 138.1 vs not employed 433.7 ± 160.8; P < 0.001) compared to patients not employed after OLT. Employment before OLT(P < 0.001), age(P < 0.01) and SF-36 sum score 12 mo after OLT(P < 0.01) but not HE before OLT or neurological complications after OLT were independent predictors of the employment status after OLT.CONCLUSION HE before and neurological complications after OLT have no impact on the employment status 12 mo after OLT. Instead younger age and employment before OLT predict employment one year after OLT.Henning Pflugrad Anita B Tryc Annemarie Goldbecker Christian P Strassburg Hannelore Barg-Hock Jürgen Klempnauer Karin Weissenborn 2017World Journal of Hepatology2017,9,10:3
