Proximal row carpectomy generates better mid- to long-term outcomes than four-corner arthrodesis for post-traumatic wrist arthritis: a meta-analysis.

Orthop Traumatol Surg Res 2022 Aug 5:103373. Epub 2022 Aug 5.

Elsan, Rue la Boétie 58, 75008 Paris, France.

Introduction: In posttraumatic wrist arthritis of intermediate severity, two main palliative procedures are used to preserve some mobility in the wrist: proximal row carpectomy (PRC) and scaphoid excision followed by four corner arthrodesis (4CA). Despite satisfactory overall results, the debate continues about which one provides the best results and long-term outcomes, particularly prevention of arthritis progression. Recent comparative studies now provide us with information about mid- and long-term results. Read More

Motion-Aligned 4D-MRI Reconstruction using Higher Degree Total Variation and Locally Low-Rank Regularization.

Magn Reson Imaging 2022 Aug 5. Epub 2022 Aug 5.

School of Electronics and Information Engineering, Harbin Institute of Technology, Harbin, China. Electronic address:

Four-dimensional magnetic resonance imaging (4D-MRI) is becoming increasingly important in radiotherapy treatment planning for its ability to simultaneously provide 3D structural information and temporal profiles of the examined tissues in a non-ionizing manner. However, the relatively long acquisition time and the resulting motion artifacts severely limit the further application of 4D-MRI. In this paper, we propose a novel motion-aligned reconstruction method based on higher degree total variation and locally low-rank regularization (maHDTV-LLR) to recover 4D MR images from the highly undersampled Fourier coefficients.

Deciphering the effect of exogenous lignocellulases addition on the composting efficiency and microbial communities.

Bioresour Technol 2022 Aug 5:127751. Epub 2022 Aug 5.

Jiangsu Provincial Key Lab of Solid Organic Waste Utilization, Jiangsu Collaborative Innovation Center of Solid Organic Wastes, Educational Ministry Engineering Center of Resource-saving fertilizers; Nanjing Agricultural University, Nanjing 210095, Jiangsu, People' Republic of China.

This study aimed to reveal the potential effects of exogenous lignocellulases addition on the composting efficiency and microbial communities. The lignocellulases addition at the mesophilic phase (MEP) greatly expedited the substrate conversion and the rise of temperature at the initial stage, driving the early arrival of thermophilic phase (THP), caused by the positive effects of Sphingobacterium and Brevundimonas. When being added at the THP, the potential functions and interactions of microbial communities were stimulated, especially for Thermobispora and Mycothermus, which prolonged the duration of the THP and expedited the humic acid formation.

Monoclonal antibody sequence variants disguised as fragments: identification, characterization, and their removal by purification process optimization.

J Pharm Sci 2022 Aug 5. Epub 2022 Aug 5.

Biopharmaceuticals Development, R&D, AstraZeneca, Gaithersburg, MD, US.

During early stage development of a therapeutic IgG1 monoclonal antibody, high levels of low molecular weight (LMW) peaks were observed by high performance size-exclusion chromatography and capillary electrophoresis. Further characterization of the LMW peak enriched HPSEC fractions using reversed phase liquid chromatography coupled to mass spectrometry showed these LMW species were 47 kDa and 50 kDa in size. However, the measured masses could not be matched to any fragments resulting from peptide bond hydrolysis. Read More

Reduction of DUSP4 contributes to podocytes oxidative stress, insulin resistance and diabetic nephropathy.

Biochem Biophys Res Commun 2022 Jul 30;624:127-133. Epub 2022 Jul 30.

From the Research Center of the Centre Hospitalier Universitaire de Sherbrooke, Université de Sherbrooke, Québec, Canada; Division of Endocrinology, Department of Medicine, Université de Sherbrooke, Québec, Canada. Electronic address:

Podocytes are insulin-sensitive cells, and their loss is critical in diabetic nephropathy (DN) progression that could lead to end-stage kidney disease. We have previously shown that decreased DUSP4 expression caused elevated JNK phosphorylation in the diabetic kidney and worsened DN characteristics. Yet, the role of DUSP4 in diabetic podocyte insulin resistance and the progression of DN remains unclear. Read More

Conditional GANs based system for fibrosis detection and quantification in Hematoxylin and Eosin whole slide images.

Med Image Anal 2022 Jul 19;81:102537. Epub 2022 Jul 19.

Department of Pathology and Laboratory Medicine, University of Louisville, Louisville, KY, USA.

Assessing the degree of liver fibrosis is fundamental for the management of patients with chronic liver disease, in liver transplants procedures, and in general liver disease research. The fibrosis stage is best assessed by histopathologic evaluation, and Masson's Trichrome stain (MT) is the stain of choice for this task in many laboratories around the world. However, the most used stain in histopathology is Hematoxylin Eosin (HE) which is cheaper, has a faster turn-around time and is the primary stain routinely used for evaluation of liver specimens.

Disparities in Psychosocial Distress Screening and Management of Lung and Ovarian Cancer Survivors.

JCO Oncol Pract 2022 Aug 8:OP2200078. Epub 2022 Aug 8.

American College of Surgeons, Commission on Cancer, Chicago, IL.

Purpose: Since 2016, the American College of Surgeons' Commission on Cancer (CoC) has required routine distress screening (DS) of cancer survivors treated in their accredited facilities to facilitate early identification of survivors with psychosocial concerns. Lung and ovarian cancer survivors have relatively low 5-year survival rates and may experience high levels of distress. We examined the extent to which ovarian and lung cancer survivors received CoC-mandated DS and whether DS disparities exist on the basis of diagnosis, sociodemographic factors, or facility geography (urban/rural).
