2018 Journal of Veterinary Internal Medicine  
Threshold values for total nucleated cell count (TNCC) and protein concentration in cerebrospinal fluid (CSF) of downer dairy cows suggestive of a spinal cord lesion were recently published. Objectives: Determine short-and long-term survival of downer cows that underwent CSF analysis using the reported threshold values. Evaluate the prognostic value of these threshold values to predict short-and long-term survival. Animals: Two hundred and fourteen downer adult dairy cows that underwent CSF

Medical records of downer adult dairy cows presented to the hospital between January 2006 and October 2014 for which CSF analysis results were available were studied. Short-term (discharge from hospital) and long-term (completion of lactation) survival were determined and compared in accordance with CSF TNCC and protein concentration, using a Chi-square test. Results: Cows with CSF TNCC and/or protein concentration above the threshold values had a significantly lower short-term survival rate (P = .02). The odds of nonsurvival of cows with one or both CSF values above the threshold values was 2.16 times higher than the odds for cows with values under the threshold values. CSF TNCC >4.5 cells/μL had sensitivity and specificity of 17.3% (95% CI: 10.7%-25.7%) and 92.3% (95% CI: 85.4%-96.6%), respectively, for predicting short-term nonsurvival. CSF protein concentration >0.39 g/L had sensitivity and specificity of 20.9% (95% CI: 13.7%-29.7%) and 91.4% (95% CI: 84.2%-96.0%), respectively. Conclusions: CSF analysis above threshold values used in this study is associated with increased odds of short-term nonsurvival.

Assessing the capabilities of the Surface Water and Ocean Topography (SWOT) mission for large lake water surface elevation monitoring under different wind conditions

Abstract. Lakes are important sources of freshwater and provide essential ecosystem services. Monitoring their spatial and temporal variability, and their functions, is an important task within the development of sustainable water management strategies. The Surface Water and Ocean Topography (SWOT) mission will provide continuous information on the dynamics of continental (rivers, lakes, wetlands and reservoirs) and ocean water bodies. This work aims to contribute to the international effort

For this purpose, a hydrodynamic model was set up over Mamawi Lake, Canada, and different wind scenarios on lake hydrodynamics were simulated. The derived water surface elevations (WSEs) were compared to synthetic elevations produced by the Jet Propulsion Laboratory (JPL) SWOT high resolution (SWOT-HR) simulator. Moreover, water storages and net flows were retrieved from different possible SWOT orbital configurations and synthetic gauge measurements. In general, a good agreement was found between the WSE simulated from the model and those mimicked by the SWOT-HR simulator. Depending on the wind scenario, errors ranged between approximately −2 and 5 cm for mean error and from 30 to 70 cm root mean square error. Low spatial coverage of the lake was found to generate important biases in the retrievals of water volume or net flow between two satellite passes in the presence of local heterogeneities in WSE. However, the precision of retrievals was found to increase as spatial coverage increases, becoming more reliable than the retrievals from three synthetic gauges when spatial coverage approaches 100 %, demonstrating the capabilities of the future SWOT mission in monitoring dynamic WSE for large lakes across Canada.

A rare presentation of skull-base osteomyelitis with neurovascular sheath extension following external otitis resolved by PET/MRI

Abbreviations 18 F-FDG 18 F-Fluorodeoxyglucose PET Positron emission tomography MRI Magnetic resonance imaging SUV Standardized uptake value 18 F-FDG PET/MRI was performed on a 67-year-old diabetic man referred for staging of a possible tumour revealed by multiple cranial nerve impairment (VII, IX, X, XI and XII) and skull-base osteolysis on CT.

The contrast-enhanced T1weighted MRI image (b) reveals hyperintensity in the clivus and the right occipital condyle/petrous apex, infiltrating contiguous soft tissues (full arrow), and focal posterior leptomeningeal enhancement (dotted arrow). The areas of hyperintensity coincide on the fused image (c) with the 18 F-FDG uptake, and are clearly seen on the diffusion-weighted image (d). Linear 18 F-FDG uptake in the right neurovascular structures is also shown on the coronal slices (e-g) and maximum intensity projection (h, arrowhead) with jugular and carotid compression on MRI. The association between moderate, diffuse 18 F-FDG uptake and infiltrative contrast enhancement suggested osteomyelitis. The medical history indicated that this infection probably complicated a right otitis externa which occurred several weeks before and was treated with broad-spectrum antibiotics. Signs of active otitis are still visible on the PET/MRI images that show mild 18 F-FDG uptake (stars, SUVmax 2.0) and contrast-enhanced wall thickening of the external auditory canal. The diagnosis was confirmed by an endonasal endoscopy biopsy carried out a few days later, that showed Pseudomonas aeruginosa and Stenotrophomonas maltophilia infections, and allowed an adapted antibacterial therapy to be started. This case illustrates the complementary value of PET and MRI for characterizing cell metabolism and the tissue microenvironment in osteomyelitis of the vertebrae [1] and skull base [2, 3] in a one-shot setting.

2020 Remote Sensing  
The Surface Water and Ocean Topography (SWOT) space mission will map surface area and water level changes in lakes at the global scale. Such new data are of great interest to better understand and model lake dynamics as well as to improve water management. In this study, we used the large-scale SWOT simulator developed at the French Space National Center (CNES) to estimate the expected measurement errors of the water level of different water bodies in France. These water bodies include five

The results show that the SWOT mission will allow to observe water levels with a precision of a few tens of centimeters (10 cm for the largest water reservoir (Orient), 23 km2), even for the small gravel pits of size of a few hectares (standard deviation error lower than 0.25 m for water bodies larger than 6 ha). The benefit of the temporal sampling for water level monitoring is also highlighted on time series of pseudo-observations based on real measurements perturbed with the simulated noise errors. Then, the added value of these future data for the simulation of lake energy budgets is shown using the FLake lake model through sensitivity experiments. Results show that the SWOT data will help to model the surface temperature of the studied water bodies with a precision better than 0.5 K and the evaporation with an accuracy better than 0.2 mm/day. These large improvements compared to the errors obtained when a constant water level is prescribed (1.2 K and 0.6 mm/day) demonstrate the potential of SWOT for monitoring the lake energy budgets at global scale in addition to the other foreseen applications in operational reservoir management.
