Repeat limited fasciectomy is a safe and effective treatment for recurrence of Dupuytren's disease.

Bone Joint J 2021 May;103-B(5):946-950

Department of Trauma and Orthopaedic Surgery, St Mary's Hospital, London, UK.

Establishment of a Target, Suspect, and Functional Group-Dependent Screening Strategy for Organophosphate Esters (OPEs): "Into the Unknown" of OPEs in the Sediment of Taihu Lake, China.

Environ Sci Technol 2021 05 23;55(9):5836-5847. Epub 2021 Apr 23.

Jiangsu Key Laboratory of Chemical Pollution Control and Resources Reuse, School of Environmental and Biological Engineering, Nanjing University of Science and Technology, Nanjing 210094, P. R. China.

Current environmental monitoring studies are generally confined to several target organophosphate esters (OPEs), and there is a lack of strategies for comprehensively screening all potential OPEs in environmental samples. Here, an effective and accurate strategy was developed for the target, suspect, and functional group-dependent screening of OPEs by the use of ultrahigh-performance liquid chromatography-Q Exactive hybrid quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS), and this strategy was applied for the analysis of = 74 sediment samples (including 23 surface sediment samples and 51 sediment core samples) collected from Taihu Lake (eastern China) in 2019. In these analyzed samples, we successfully identified = 35 OPEs, and 23 of them were reported in this region for the first time. Read More

Identifying global favourable habitat for early juvenile loggerhead sea turtles.

J R Soc Interface 2021 02 24;18(175):20200799. Epub 2021 Feb 24.

National Center for Atmospheric Research, Boulder, CO 80305, USA.

Loggerhead sea turtles () nest globally on sandy beaches, with hatchlings dispersing into the open ocean. Where these juveniles go and what habitat they rely on remains a critical research question for informing conservation priorities. Here a high-resolution Earth system model is used to determine the biophysical geography of favourable ocean habitat for loggerhead sea turtles globally during their first year of life on the basis of ocean current transport, thermal constraints and food availability (defined here as the summed lower trophic level carbon biomass).

Anal Chem 2021 03 12;93(8):3976-3986. Epub 2021 Feb 12.

Australian National Phenome Center, and Center for Computational and Systems Medicine, Health Futures Institute, Murdoch University, Harry Perkins Building, Perth WA6150, Australia.

We have applied nuclear magnetic resonance spectroscopy based plasma phenotyping to reveal diagnostic molecular signatures of SARS-CoV-2 infection combined diffusional and relaxation editing (DIRE). We compared plasma from healthy age-matched controls ( = 26) with SARS-CoV-2 negative non-hospitalized respiratory patients and hospitalized respiratory patients ( = 23 and 11 respectively) with SARS-CoV-2 rRT-PCR positive respiratory patients ( = 17, with longitudinal sampling time-points). DIRE data were modelled using principal component analysis and orthogonal projections to latent structures discriminant analysis (O-PLS-DA), with statistical cross-validation indices indicating excellent model generalization for the classification of SARS-CoV-2 positivity for all comparator groups (area under the receiver operator characteristic curve = 1).
