Same Day versus Staged Total Knee Arthroplasty: Do Cost Savings Justify the Risk?

J Knee Surg 2020 Jul 13. Epub 2020 Jul 13.

Rubin Institute for Advanced Orthopedics, Center for Joint Preservation and Replacement, Sinai Hospital of Baltimore, Baltimore, Maryland.

Same-day bilateral total knee arthroplasties (BTKAs) are associated with increased complications compared with staged procedures; however, as complication rates and lengths of stay (LOS) for same-day procedures decrease, they may become attractive alternatives to staged procedures. The void of recent nationwide studies comparing the 30-day total cost and risks of these procedures inspired this propensity matched review. Therefore, we compared 30-day outcomes in staged and same-day BTKAs occurring in 2016 and 2017 using the National Readmission Database (NRD), a nationwide database. Read More

Controlled diffusion of nanoparticles by viscosity gradient for photonic crystal with dual photonic band gaps.

Nanotechnology 2020 Jul 13. Epub 2020 Jul 13.

Organic Solids Laboratory, Chinese Academy of Sciences - Institute of Chemistry, Beijing 100080, P R China, Beijing, CHINA.

Coalescence of droplets containing nanoparticles has been paid much attention to fabricate functional photonic crystal (PC) patterns. However, most of them focus on the coalescence of droplets containing the same nanoparticles. Nowadays, an active challenge comes from the coalescence of droplets containing different nanoparticles due to the spontaneous mutual diffusion of different nanoparticles between coalescing miscible droplets driven by the released Gibbs free energy.

The benefits of a Bayesian analysis for the characterization of magnetic nanoparticles.

Nanotechnology 2020 Jul 13. Epub 2020 Jul 13.

Physics and Materials Science Research Unit, Universite du Luxembourg, 162A Avenue de la Faïencerie, Luxembourg, 1511, LUXEMBOURG.

Magnetic nanoparticles offer a unique potential for various biomedical applications, but prior to commercial usage a standardized characterization of their structural and magnetic properties is required. For a thorough characterization, the combination of conventional magnetometry and advanced scattering techniques has shown great potential. In the present work, we characterize a powder sample of high-quality iron oxide nanoparticles that are surrounded with a homogeneous thick silica shell by DC magnetometry and magnetic small-angle neutron scattering (SANS).

In the presence of Hg, the resulting red-orange fluorescence (under UV light) and naked eye red color of RS are supposed to be used for quantitative and qualitative measurement of Hg. Further fluorescent titration and analysis demonstrate that RS can selectively detect Hg within 1 s with a low limit of detection (LOD) of 16 nM in acetonitrile media, meanwhile, the association constant (K) was calculated to be 0.

Cascade extraction of proteins and feruloylated arabinoxylans from wheat bran.

Food Chem 2020 Jul 6;333:127491. Epub 2020 Jul 6.

Division of Glycoscience, Department of Chemistry, School of Engineering Sciences in Chemistry, Biotechnology and Health, KTH Royal Institute of Technology, Stockholm, Sweden. Electronic address:

A cascade process for the sequential recovery of proteins and feruloylated arabinoxylan from wheat bran is proposed, involving a protein isolation step, enzymatic destarching and subcritical water extraction. The protein isolation step combining lactic acid fermentation and cold alkaline extraction reduced the recalcitrance of wheat bran, thus improving the total yields of the subsequent subcritical water extraction. The time evolution of subcritical water extraction of feruloylated arabinoxylan was compared at two temperatures (160 °C and 180 °C). Read More

Development and validation of a method for the analysis of five diamide insecticides in edible mushrooms using modified QuEChERS and HPLC-MS/MS.

Food Chem 2020 Jul 3;333:127468. Epub 2020 Jul 3.

Zhengzhou Fruit Research Institute, Chinese Academy of Agricultural Sciences, Zhengzhou 450009, China. Electronic address:

In this study, a new method for simultaneous determination of cyantraniliprole, chlorantraniliprole, tetrachlorantraniliprole, cyclaniliprole and flubendiamide in edible mushrooms by high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) combined with a modified QuEChERS procedure. The samples were extracted using acetonitrile and then cleaned up by primary secondary amine (PSA) and octadecylsilane (C18). The determination of these insecticides was achieved in less than 5 min using an electrospray ionization source in positive mode (ESI+) for cyantraniliprole and chlorantraniliprole, while negative mode (ESI-) for tetrachlorantraniliprole, cyclaniliprole and flubendiamide.

Celiac disease is an autoimmune illness activated by gluten peptides produced during gastrointestinal digestion. A simulated in vitro digestion of gluten was conducted to define the profile and kinetic release pattern of immunogenic gluten peptides in a physiologically relevant food matrix. White bread was digested using the INFOGEST in vitro standardised digestion protocol from 0 to 240 min and subsequently analysed by SDS-PAGE, quantitative LC-MS/MS, untargeted LC-MS/MS and ELISA.

Gelatin enhances the flavor of chicken broth: A perspective on the ability of emulsions to bind volatile compounds.

Food Chem 2020 Jul 3;333:127463. Epub 2020 Jul 3.

Anhui Engineering Laboratory for Agro-products Processing, College of Tea & Food Science and Technology, Anhui Agricultural University, Hefei 230036, China.

The mechanism of flavor retention in chicken broth from the perspective of gelatin affecting the flavor-binding ability of emulsions was investigated. Results showed that fat was the important reservoir for aroma compounds in the emulsion. The particle sizes of emulsions significantly decreased with prolonged stewing time of gelatin, which was consistent with the results from confocal laser scanning microscopy and interfacial tension.

A simple design for the validation of a FT-NIR screening method: Application to the detection of durum wheat pasta adulteration.

Food Chem 2020 Jul 4;333:127449. Epub 2020 Jul 4.

European Commission, Joint Research Centre (JRC), Geel, Belgium. Electronic address:

The demand for the development of fast, easy-to-use and low-cost analytical methods for food adulteration analysis has being increasing in the last years. Although infrared spectroscopic techniques offer these advantages, the validation of screening methods requiring the application of multivariate data treatment is less frequently described in literature thus limiting their use as routine tools in control laboratories for food fraud monitoring. In this paper, an EU-validation procedure for screening methods was successfully applied to a multivariate FT-NIR spectroscopic method for the screening of durum wheat pasta samples adulterated with common wheat at the screening target concentration of 3%.
