Combinations of three different injected doses of iohexol (450, 600, and 750 mg/kg) and injection durations (5, 10, and 15 seconds) were used. The CT values at the aorta, portal vein, and hepatic parenchyma were measured to create a time-density curve, and CTP parameters were measured s...

Compatibility and stability of non-ionic iodinated contrast media in peritoneal dialysis solution and safe practice considerations for CT peritoneography
CONCLUSIONS: The addition of commonly used non-ionic iodinated contrast agents to 1.5% dextrose dialysis solution is chemically stable, meeting the criteria set forth in the standards and guidelines of the US Pharmacopeia and the Institute of Safe Medication Practices. A protocol for performing CT peritoneography is recommended herein to facilitate patient safety and diagnostic reliability of the imaging study.PMID:35505602 | DOI:10.1177/08968608221096562 (Source: Peritoneal Dialysis International)

Evaluation of contrast-enhanced ultrasonography with Sonazoid ® in visualization of local anesthetic distribution in rectus sheath block: a prospective, clinical study
ConclusionSonazoid diluted 100-fold® was clearly visualized real-time, and the enhancement was sustained and measurable after RSB. Sonazoid® could potentially be used for the contrast agent of US-guided nerve block. (Source: Journal of Anesthesia)

The trajectory of renal function following mechanical circulatory support and subsequent heart transplantation
ConclusionsIn patients with advanced heart failure, measured GFR improved after MCS with no difference between pulsatile and CF-pumps. The total study group showed no further increase in GFR following HTx, but in certain subgroups, including patients aged 35 –54 years and those treated during the latest era (2012–2018), renal function appeared to improve after transplant.

Chronic Renal Failure-Causes, Clinical Findings, Treatments and Prognosis
Chronic kidney disease (CKD) is rare in horses with an overall prevalence reported to be 0.12%. There is often a continuum from Acute Kidney Injury (AKI) to CKD, and patients with CKD may be predisposed to episodes of AKI. The most common clinical signs are non-specific with weight loss, polyuria/polydipsia and ventral edema. Less common clinical signs are poor appetite and performance, dull hair coat, oral ulcerations, gastro-intestinal ulceration, gingivitis, dental tartar and diarrhea. Rarely, horses may develop forebrain signs. Creatinine increases when at least 2/3 of kidney function have been lost and a more accurate...

Toward efficient electrocatalytic degradation of iohexol using active anodes: A laser-made versus commercial anodes
Chemosphere. 2022 Mar 21:134350. doi: 10.1016/j.chemosphere.2022.134350. Online ahead of print.ABSTRACTThe X-ray iodinated contrast medium iohexol is frequently detected in aquatic environments due to its high persistence and the inefficiency of its degradation by conventional wastewater treatments. Hence, the challenge faced in this study is the development of an alternative electrochemical treatment using active anodes. We investigate the oxidation of iohexol (16.42 mg L-1) using different operating conditions, focusing on the role of different mixed metal oxide anodes in the treatment efficiency. The electrocatalytic ef...
