Gadolinium Presence in Rat Skin: Assessment of Histopathologic Changes Associated with Small Fiber Neuropathy.

Background The presence of gadolinium traces in the skin after administration of gadolinium-based contrast agents (GBCAs) raised safety concerns regarding a potential association with small fiber neuropathy (SFN). Purpose To investigate signs of SFN in rat foot pads by quantification of the intraepidermal nerve fiber density (IENFD) after multiple GBCA administrations and to evaluate gadolinium concentration, chemical species, and clearance. Materials and Methods Fifty rats received eight intravenous injections of either gadodiamide, gadobutrol, gadoterate, gadoteridol (8 × 0.

The effects of prolactin receptor blockade in a murine endometriosis interna model.

Endometriosis in an estrogen-dependent disease that is characterized by the presence of endometrial tissue outside the uterine cavity leading to pain and infertility in many affected women. Highly efficient treatment options which create a hypo-estrogenic environment can cause side effects such as hot flushes and bone mass loss that are not favorable for premenopausal women. Previous work has demonstrated that increased local or systemic prolactin seems to be involved in the pathogenesis of endometriosis.

The Macrocyclic Gadolinium-Based Contrast Agents Gadobutrol and Gadoteridol Show Similar Elimination Kinetics From the Brain After Repeated Intravenous Injections in Rabbits.

Materials And Methods: Male white New Zealand rabbits (2.4-3.1 kg) in 2 study groups (n = 21 each) received 3 injections of either gadobutrol or gadoteridol at 0.

Factor VIII activity of BAY 94-9027 is accurately measured with most commonly used assays: Results from an international laboratory study.

Introduction: Discrepancies in the measurement of modified factor VIII (FVIII) products have been recognized, highlighting the need for adjustments in clinical laboratory practices to ensure effective monitoring of patients treated with these products, particularly using the one-stage (activated partial thromboplastin time [aPTT]) assay.

Aim: To assess the ability of clinical laboratories to measure the activity of BAY 94-9027, a PEGylated extended half-life FVIII product, using routine (predominantly one-stage) assays in clinical laboratories METHODS: Blinded samples of FVIII-deficient plasma spiked with defined levels of BAY 94-9027 and a recombinant FVIII product comparator were provided to 52 clinical laboratories that routinely conduct FVIII testing. Samples were provided at 3 concentrations (low, medium and high), and laboratories analysed the samples using routine in-house one-stage and, when available, chromogenic assays.

Behavioral Economics: A New Lens for Understanding Genomic Decision Making.

Purpose: This article seeks to take the next step in examining the insights that nurses and other healthcare providers can derive from applying behavioral economic concepts to support genomic decision making. As genomic science continues to permeate clinical practice, nurses must continue to adapt practice to meet new challenges. Decisions associated with genomics are often not simple and dichotomous in nature.
