Automation of parenteral nutrition: impact on process and cost analysis.

Objectives: On the basis of its safety and accuracy, automation is recommended for parenteral nutrition (PN). The aim of this study was to highlight the changes in practices related to the automation of PN and to perform a cost study comparing manual vs automated production costs.

Methods: We conducted a micro-costing study using 1 year of manual production data for adult, neonatal and paediatric PN bagsat a hospital.

Place of magistral preparations to continue the treatment if the drug is commercially stopped worldwide? A case report of a 10-year-old child with subacute sclerosing panencephalitis (SSPE) requiring inosiplex.

Subacute sclerosing panencephalitis (SSPE) is a late-onset and fatal viral disease caused by persistent infection of the central nervous system by measles virus (MeV). We present the case of a 10-year-old child from South Asia affected by SSPE, stabilized with a combination of intrathecal interferon-α2b (INF-α2b) injections and oral inosiplex and how we continued the treatment when inosiplex was commercially stopped worldwide.

A quality by design approach for the qualification of automating compounding device for parenteral nutrition.

Automated compounding device (ACD) are increasingly used for parenteral nutrition (PN) bag production, and their acquisition must be sufficiently thought. The law requires the qualification of these ACD, but did not specify the tests to be performed. The quality by design (QbD) risk based approach allowed to define the quality target product profile in order to acquire the best ACD for each unit, and thanks a risk analysis permitted to define the critical quality attributes (CQA).

Development and Validation of Analytical Methods for Radiochemical Purity of Lu-PSMA-1.

Prostate Specific Membrane Antigen (PSMA) is a highly relevant target in nuclear medicine due to its overexpression in prostate cancer. The Ga/Lu-PSMA-1 combination is a theranostic agent for the detection and treatment of tumors overexpressing the PSMA target. Specifically, Lu-PSMA-1 is used in the treatment of castration-resistant prostate cancer that is ineffective or intolerant to the latest generation of chemotherapy and/or hormone therapy.

Comparison of three automated compounding devices for parenteral nutrition according to four key technical tests.

Objectives: Automation of parenteral nutrition (PN) preparation is nowadays a recommended practice in order to reduce human errors and thus improve the safety and accuracy of the finished product. Other benefits of automation may include full documentation of preparation and a reduction in personnel requirements or staff injuries. The market of automation compounding presents different automated compounding devices (ACDs).

Preclinical and clinical evaluation of a new method to assess cardiac insulin resistance using nuclear imaging.

Background: Myocardial insulin resistance (IR) could be a predictive factor of cardiovascular events. This study aimed to introduce a new method using I-6-deoxy-6-iodo-D-glucose (6DIG), a pure tracer of glucose transport, for the assessment of IR using cardiac dynamic nuclear imaging.

Methods: The protocol evaluated first in rat-models consisted in two 6DIG injections and one of insulin associated with planar imaging and blood sampling.

Safety, Biodistribution, and Dosimetry of 123I-6-Deoxy-6-Iodo-D-Glucose, a Tracer of Glucose Transport, in Healthy and Diabetic Volunteers.

Purpose: Insulin resistance is a key feature of the metabolic syndrome and type 2 diabetes, in which noninvasive assessment is not currently allowed by any methodology. We previously validated an iodinated tracer of glucose transport (6DIG) and a new methodology for the in vivo quantification of cardiac insulin resistance in rodents. The aim of this study was to investigate the safety, biodistribution, and radiation dosimetry of this method using I-6DIG in 5 healthy and 6 diabetic volunteers.

Sympathetic cardiac function in early sepsis: Noninvasive evaluation with [I]-meta-iodobenzylguanidine (I-MIBG) in vivo SPECT imaging.

Background: Sympathetic system abnormalities have been reported in sepsis-related cardiac dysfunction. The present study aimed at evaluating the potential of the norepinephrine radiolabeled analogue [I]-meta-iodobenzylguanidine (I-MIBG) for the noninvasive assessment of modifications in cardiac sympathetic activity occurring in lipopolysaccharide (LPS)-induced experimental acute sepsis by single-photon emission computed tomographic imaging (SPECT).

Methods And Results: Sepsis was induced in male Wistar rats by intraperitoneal injection of 10 mg·kg lipopolysaccharide (n = 16), whereas control animals (n = 7) were injected with vehicle (NaCl 0.

Radioiodine therapy in benign thyroid disorders. Evaluation of French nuclear medicine practices.

Objectives: Radioiodine is currently used routinely in the treatment of hyperthyroidism including Graves' disease (GD), toxic multinodular goitre (TMNG) and toxic solitary nodule (TSN) but no consensus exists on the most appropriate way to prescribe iodine--fixed dose or calculated doses based on the gland size or turnover of (131)I. We carried out the first nationwide French survey assessing the current practices in radioiodine treatment of hyperthyroidism.

Material And Methods: A questionnaire was sent to French nuclear medicine hospital units and cancer treatment centres (n=69) about their practices in 2012.

Periaortic brown adipose tissue as a major determinant of [¹⁸F]-fluorodeoxyglucose vascular uptake in atherosclerosis-prone, apoE-/- mice.

Background: [18F]-fluorodeoxyglucose (FDG) has been suggested for the clinical and experimental imaging of inflammatory atherosclerotic lesions. Significant FDG uptake in brown adipose tissue (BAT) has been observed both in humans and mice. The objective of the present study was to investigate the influence of periaortic BAT on apolipoprotein E-deficient (apoE-/-) mouse atherosclerotic lesion imaging with FDG.

Intravenous administration of 99mTc-HMPAO-labeled human mesenchymal stem cells after stroke: in vivo imaging and biodistribution.

Human mesenchymal stem cells (hMSC) are a promising source for cell therapy after stroke. To deliver these cells, an IV injection appears safer than a local graft. We aimed to assess the whole-body biodistribution of IV-injected (99m)Tc-HMPAO-labeled hMSC in normal rats (n = 9) and following a right middle cerebral artery occlusion (MCAo, n = 9).

Optimal treatment of painful bone metastases with Samarium EDTMP in a haemodialysis patient: effectiveness and safety of internal radiotherapy.

One of the current therapeutic approaches in the treatment of osteoblastic bone metastases uses the affinity of Samarium ((153)Sm) ethylene-diamine-tetramethylene phosphonic acid (EDTMP) for bone areas of bone turnover. As Samarium EDTMP is a beta-emitter, the radiotherapy contributes to osteoblastic bone lesion control over time. To date, the safety and effectiveness of Samarium therapy have not been established in patients with renal impairment.

Can the sentinel lymph node technique affect decisions to offer internal mammary chain irradiation?

Purpose: Identification of the sentinel lymph node (SLN) for small mammary tumours (cT1N0) sometimes leads to detection of internal mammary chain (IMC) drainage. This information is often ignored by physicians. The present study sought to determine the frequency with which an internal mammary SLN was identified by peritumoral injection of radioactive tracer, and then to determine the patients in whom identification of an internal mammary SLN could have an impact on the radiation treatment plan.

How to combine hygiene and radiation protection for radiopharmaceuticals preparation? Analysis in France and propositions.

Radiopharmaceuticals for intravenous administration are considered as sterile medicinal products. Their preparation in hospitals involves adherence to regulations on radiation protection as well as to sterility requirements for parenteral administration. These two basic aspects are often opposite, making the working conditions difficult to define.
