AV-Net: Deep learning for fully automated artery-vein classification in optical coherence tomography angiography [PDF]

arXiv, 2020
This study is to demonstrate deep learning for automated artery-vein (AV) classification in optical coherence tomography angiography (OCTA). The AV-Net, a fully convolutional network (FCN) based on modified U-shaped CNN architecture, incorporates enface OCT and OCTA to differentiate arteries and veins.

Incidence of and Risk of Mortality After Hip Fractures in Rheumatoid Arthritis Relative to the General Population

Arthritis Care &Research, EarlyView.
Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.

Incidence of Side Effects Associated With Acetaminophen in People Aged 65 Years or More: A Prospective Cohort Study Using Data From the Clinical Practice Research Datalink

Arthritis Care &Research, EarlyView.
Objective The main objective of this study is to examine the safety of oral acetaminophen at its therapeutic dose in adults aged ≥65 years. Methods This population‐based cohort study used the Clinical Practice Research Datalink‐Gold data. Participants were aged ≥65 years registered with a UK general practice for at least 12 months between 1998 and 2018.

Do surgeries for varicose veins carry a risk of deep vein thrombosis? Endovenous laser ablation and conventional saphenectomy – a comparison

Pediatria i Medycyna Rodzinna, 2017
Venous diseases, in particular varicose veins of the lower extremities, are one of the most common chronic diseases and a significant cause of morbidity in Europe and the USA. Varicose veins are considered a risk factor for deep vein thrombosis.

Active Hydrogen for Electrochemical Ammonia Synthesis

Advanced Functional Materials, EarlyView.
This review provides a comprehensive overview of the active hydrogen (H*) for electrochemical ammonia synthesis with particular attention given to the regulation of H* generation and consumption to suppress the competition of hydrogen evolution reaction and enhance the yield, selectivity, and Faradaic efficiency of ammonia.

Using an age-dependent D-dimer cut-off value increases the number of older patients in whom deep vein thrombosis can be safely excluded

Haematologica, 2012
Background D-dimer testing to rule out deep vein thrombosis is less useful in older patients because of a lower specificity. An age-adjusted D-dimer cut-off value increased the proportion of older patients (>50 years) in whom pulmonary embolism could be ...

Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

Advanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species （ROS）generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

Non-destructive three-dimensional measurement of hand vein based on self-supervised network [PDF]

arXiv, 2019
At present, supervised stereo methods based on deep neural network have achieved impressive results. However, in some scenarios, accurate three-dimensional labels are inaccessible for supervised training. In this paper, a self-supervised network is proposed for binocular disparity matching (SDMNet), which computes dense disparity maps from stereo image
