Successful implementation of outpatient R ± DHAX (rituximab, dexamethasone, oxaliplatin, cytarabine) for select patients with lymphoma: a single-center experience.

R ± DHAX has been traditionally administered to inpatient due to the timing of chemotherapy administration and the perceived need for close monitoring of adverse effects. To administer R ± DHAX outpatient, a multidisciplinary task force created clinical and educational guidelines which were implemented through two phases: pilot and expansion. The pilot program determined the feasibility of transitioning R ± DHAX outpatient at a single infusion site. The expansion phase led to a service-wide implementation across all outpatient sites. A total of 40 patients were included, of which 23 patients completed all cycles, outpatient, 12 transitioned inpatient to outpatient administration, and 5 transitioned outpatient to inpatient administration. The success rate of outpatient R ± DHAX administration was 90% (36 patients successfully completed outpatient administration/40 total patients). No cytarabine-related cerebellar or ophthalmic toxicity was reported. Outpatient R ± DHAX saved 192 hospital days. R ± DHAX could be successfully administered outpatient with minimal safety concerns and reduced hospital bed utilization.

Dietary Piperine is Transferred into the Milk of Nursing Mothers.

INTRODUCTION: The diet of breastfeeding mothers could bring nurslings into contact with flavor compounds putatively contributing to early sensory programming of the infant. The study investigates whether tastants from a customary curry dish consumed by mothers are detectable in their milk afterwards and can be perceived by the infant. METHODS AND RESULTS: Sensory evaluation identifies pungency as the dominating taste impression of the curry dish. Its ingredients of chili, pepper, and ginger suggest the flavor compounds capsaicin, piperine, and 6-gingerol as analytical targets. Breastfeeding mothers are recruited for an intervention trial involving the consumption of the curry dish and subsequent collection of milk samples for flavor compound analysis. Targeted and untargeted mass spectrometric (MS)- investigations identify exclusively piperine as an intervention-derived compound in human milk. However, concentrations are below the human taste threshold. CONCLUSION: Piperine from pepper-containing foods transfers into the mother's milk within 1 h and is delivered to the nursling. Concentrations of 50 and 200 nM of piperine are 70-350 times below the human taste threshold, but TRPV1 (Transient Receptor Potential Vanilloid-1 ion channel) desensitization through frequent exposure to sub-taste-threshold concentrations could contribute to an increased tolerance at a later age.

Characterization of Bitter and Astringent Off-Taste Compounds in Potato Fibers.

Applying the sensomics approach, a combination of activity-guided fractionation and taste dilution analysis (TDA) followed by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), ultrahigh-performance liquid chromatography time-of-flight mass spectrometry (UHPLC-TOF-MS), and one-dimensional and two-dimensional nuclear magnetic resonance spectroscopy (1D/2D NMR) allowed the elucidation of key off-taste compounds in potato dietary fiber isolates. Previously already having been described as off-taste compounds in potato tubers, saponins α-chaconine and α-solanine were shown to be also major contributors to overall off-taste in potato fiber isolates. Moreover, fatty acids as well as fatty acid oxidation products, namely, E-9,10,13-trihydroxy-octadec-11-enoic acid as well as newly identified compounds hexadecyl(E/Z)-ferulate and octadecyl(E/Z)-ferulate, were shown to be key inducers to off-taste in the isolates, exhibiting taste recognition thresholds between 18 and 981 µmol/L. This paper demonstrates the isolation, structure determination, quantitation as well as sensory attributes of these key off-taste compounds.
