| 14 | Impact of psychosocial comorbidities on clinical outcomes after liver transplantation: Stratification of a high-risk population显示文摘BACKGROUND Liver transplantation is the accepted standard of care for end-stage liver disease due to a variety of etiologies including decompensated cirrhosis, fulminant hepatic failure, and primary hepatic malignancy. There are currently over 13000 candidates on the liver transplant waiting list emphasizing the importance of rigorous patient selection. There are few studies regarding the impact of additional psychosocial barriers to liver transplant including financial hardship, lack of caregiver support, polysubstance abuse, and issues with medical noncompliance. We hypothesized that patients with certain psychosocial comorbidities experienced worse outcomes after liver transplantation. AIM To assess the impact of certain pre-transplant psychosocial comorbidities on outcomes after liver transplantation. METHODS A retrospective analysis was performed on all adult patients from 2012-2016. Psychosocial comorbidities including documented medical non-compliance, polysubstance abuse, financial issues, and lack of caregiver support were collected. The primary outcome assessed post-transplantation was survival. Secondary outcomes measured included graft failure, episodes of acute rejection, psychiatric decompensation, number of readmissions, presence of infection, recidivism for alcohol and other substances, and documented caregiver support failure.RESULTS For the primary outcome, there were no differences in survival. Patients with a history of psychiatric disease had a higher incidence of psychiatric decompensation after liver transplantation (19% vs 10%, P = 0.013). Treatment of psychiatric disorders resulted in a reduction of the incidence of psychiatric decompensation (21% vs 11%, P = 0.022). Patients with a history of polysubstance abuse in the transplant evaluation had a higher incidence of substance abuse after transplantation (5.8% vs 1.2%, P = 0.05). In this cohort, 15 patients (3.8%) were found to have medical compliance issues in the transplant evaluation. Of these specific patients, 13.3% were found to have substance abuse after transplantation as opposed to 1.3% in patients without documented compliance issues (P = 0.03). CONCLUSION Patients with certain psychosocial comorbidities had worse outcomes following liver transplantation. Further prospective and multi-center studies are warranted to properly determine guidelines for liver transplantation regarding this highrisk population. | Neil Bhogal Amaninder Dhaliwal Elizabeth Lyden Fedja Rochling Marco Olivera-Martinez | 2019 | World Journal of Hepatology2019，11，8： | 0 |
| 15 | Impact of sarcopenia on mortality in patients undergoing liver retransplantation显示文摘BACKGROUND Sarcopenia,which is a loss of skeletal muscle mass,has been reported to increase post-transplant mortality and morbidity in patients undergoing the first liver transplant.Cross-sectional imaging modalities typically determine sarcopenia in patients with cirrhosis by measuring core abdominal musculatures.However,there is limited evidence for sarcopenia related outcomes in patients undergoing liver re-transplantation(re-OLT).AIM To evaluate the risk of mortality in patients with pre-existing sarcopenia following liver re-OLT.METHODS This is a retrospective study of all adult patients who had undergone a liver re-OLT at the University of Nebraska Medical Center from January 1,2007 to January 1,2017.We divided patients into sarcopenia and no sarcopenia groups.“TeraRecon AquariusNet 4.4.12.194”software was used to evaluate computed tomography or magnetic resonance imaging of the patients done within one year prior to their re-OLT,to calculate the Psoas muscle area at L3-L4 intervertebral disc.We defined cutoffs for sarcopenia as<1561 mm2 for males and<1464 mm2 for females.The primary outcome was to compare 90 d,one,and 5-year survival rates.We also compared complications after re-OLT,length of stay,and readmission within 30 d.Survival analysis was performed with Kaplan-Meier survival analysis.Continuous variables were evaluated with Wilcoxon rank-sum tests.Categorical variables were evaluated with Fisher’s exact tests.RESULTS Fifty-seven patients were included,32 males:25 females,median age 50 years.Two patients were excluded due to incomplete information.Overall,47%(26)of patients who underwent re-OLT had sarcopenia.Females were found to have significantly more sarcopenia than males(73%vs 17%,P<0.001).Median model for end stage liver disease at re-OLT was 28 in both sarcopenia and no sarcopenia groups.Patients in the no sarcopenia group had a trend of longer median time between the first and second transplant(36.5 mo vs 16.7 mo).Biological markers,outcome parameters,and survival at 90 d,1 and 5 years,were similar between the two groups.Sarcopenia in re-OLT at our center was noted to be twice as common(47%)as historically reported in patients undergoing primary liver transplantation.CONCLUSION Overall survival and outcome parameters were no different in those with and without the evidence of sarcopenia after re-OLT. | Amaninder Dhaliwal Diana Larson Molly Hiat Lyudmila M Muinov William L Harrison Harlan Sayles Tomoki Sempokuya Marco A Olivera Fedja A Rochling Timothy M McCashland | 2020 | World Journal of Hepatology2020，12，10： | 0 |
| 16 | Unlocking the out-of-plane dimension for photonic bound states in the continuum to achieve maximum optical chirality显示文摘The realization of lossless metasurfaces with true chirality crucially requires the fabrication of three-dimensional structures,constraining experimental feasibility and hampering practical implementations.Even though the threedimensional assembly of metallic nanostructures has been demonstrated previously,the resulting plasmonic resonances suffer from high intrinsic and radiative losses.The concept of photonic bound states in the continuum(BICs)is instrumental for tailoring radiative losses in diverse geometries,especially when implemented using lossless dielectrics,but applications have so far been limited to planar structures.Here,we introduce a novel nanofabrication approach to unlock the height of individual resonators within all-dielectric metasurfaces as an accessible parameter for the efficient control of resonance features and nanophotonic functionalities.In particular,we realize out-of-plane symmetry breaking in quasi-BIC metasurfaces and leverage this design degree of freedom to demonstrate an optical all-dielectric quasi-BIC metasurface with maximum intrinsic chirality that responds selectively to light of a particular circular polarization depending on the structural handedness.Our experimental results not only open a new paradigm for all-dielectric BICs and chiral nanophotonics,but also promise advances in the realization of efficient generation of optical angular momentum,holographic metasurfaces,and parity-time symmetry-broken optical systems. | Lucca Kühner Fedja J.Wendisch Alexander A.Antonov Johannes Bürger Ludwig Hüttenhofer Leonardo de S.Menezes Stefan A.Maier Maxim V.Gorkunov Yuri Kivshar Andreas Tittl | 2023 | Light(Science & Applications)2023，12，11： | 0 |
