Physical Compatibility of Cefiderocol with Selected Intravenous Drugs During Simulated Y-site Administration.

The physical compatibility of cefiderocol for injection (prepared as a diluted 2% cefiderocol solution) with potential co-administration drug products is presented. The compatibility of cefiderocol with a selection of 91 intravenous drugs was tested at clinically relevant concentrations using the admixed volume ratio 1:1. Compatibility of the mixtures was determined by visual observations, turbidity, and particulate-matter measurements.

Serum Monitoring and Phenotype Identification of Stage I Non-Small Cell Lung Cancer Patients.

A stage I non-small cell lung cancer (NSCLC) serum profiling platform is presented which is highly efficient and accurate. Test sensitivity (0.95) for stage I NSCLC is the highest reported so far.

Topical Metered-dosing Dispenser Performance Evaluation.

Topical metered-dosing dispensers are designed for dosing accuracy and ease-of-use by the patients while protecting the packaged products from environmental exposure and contamination. The objective of this study was to evaluate the accuracy, precision, and residual of available topical metered-dosing dispensers with different types of topical cream for practical application. Triplicate samples of five different dispensers were tested.

Distinguishing patients with stage I lung cancer versus control individuals using serum mass profiling.

Serum mass profiling can discern physiological changes associated with specific disease states and their progression. Sera (86 total) from control individuals and patients with stage I nonsmall cell lung cancer or benign small pulmonary nodules were discriminated retrospectively by serum changes discerned by mass profiling. Control individuals were distinguished from patients with Stage I lung cancer or benign nodules with test sensitivities of 89% and 83%.

Serum discrimination of early-stage lung cancer patients using electrospray-ionization mass spectrometry.

The goal of this study was to evaluate the usefulness of electrospray ionization-mass spectrometry (ESI-MS) technology to distinguish sera of early-stage lung cancer patients from control individuals. ESI-MS m/z (mass divided by charge) data were generated from sera of 43 non-small cell lung cancer patients (pathological stages I and II) and 21 control individuals. Identifications of m/z peak area significances between cancer and control ESI-MS sera spectra were performed using t-tests.

Stability of Metronidazole Benzoate in SyrSpend SF One-Step Suspension System.

The objective of this study was to determine the stability of metronidazole benzoate suspension in SyrSpend SF One-Step Suspension system. The studied samples were packaged in 60-mL amber plastic prescription bottles, which were stored protected from light under controlled environmental conditions for a period of 360 days. Stability of metronidazole benzoate suspension in SyrSpend SF was assessed based on retention of initial color or appearance, pH of suspension, and recovery of metronidazole benzoate from the packaged product.

Ethanol formation in unadulterated postmortem tissues.

During the investigation of aviation accidents, postmortem samples obtained from fatal accident victims are submitted to the FAA's Civil Aerospace Medical Institute (CAMI) for toxicological analysis. During toxicological evaluations, ethanol analysis is performed on all cases. Many species of bacteria, yeast, and fungi have the ability to produce ethanol and other volatile organic compounds in postmortem specimens.
