dExtended-infusion ceftolozane-tazobactam treatment at 1.5 g every 8 h was used to treat multidrug-resistant Pseudomonas aeruginosa in a critically ill patient on continuous venovenous hemofiltration. Serum drug concentrations were measured at 1, 4, 5, 6, and 8 h after the start of infusion. Prefilter levels of ceftolozane produced a maximum concentration of drug (C max ) of 38.57 g/ml, concentration at the end of the dosing interval (C min ) of 31.63 g/ml, time to C max (T max ) of 4 h, area under the concentration-time curve from 0 to 8 h (AUC 0 -8 ) of 284.38 g · h/ml, and a half-life (t 1/2 ) of 30.7 h. The concentrations were eight times the susceptibility breakpoint for the entire dosing interval.
Objective. To identify reasons for drinking, determine the patterns of alcohol abuse, and explore relationships between drinking motives and alcohol abuse patterns in pharmacy students. Methods. A cross-sectional anonymous, voluntary, self-administered paper survey instrument was administered to first-year (P1) through third-year (P3) pharmacy students as part of a professional seminar.Results. Survey instruments were completed by 349 pharmacy students (95.9% cooperation rate). Using the Alcohol Use Disorders Identification Test criteria, 23.2% of students reported hazardous or harmful use and 67.2% of students reported consuming alcohol at hazardous levels during the past year. Students who were male (37.0%), single (25.3%), and attended the main campus (26.2%) were more likely than their counterparts to report hazardous or harmful alcohol use. Pharmacy students reported social motives as the most common reason for drinking; however, coping and enhancement motives were more predictive of harmful or hazardous alcohol use. Conclusion. Approximately 1 in 4 pharmacy students (23%) reported hazardous or harmful alcohol use. Education about the dangers of alcohol abuse and intervention programs from colleges and schools of pharmacy are recommended to help address this issue.
The aim of this study was to compare Plasma-Lyte A (PL) and sodium chloride 0.9% (NS) in regard to time to resolution of diabetic ketoacidosis (DKA) when one fluid was used predominantly over the other for resuscitation. We performed a retrospective analysis of the records of patients treated for DKA at a large, academic medical center between July 1, 2013, and July 1, 2015. Patients were placed into the PL or NS group based on the predominant fluid they received during fluid resuscitation. Serum biochemistry variables were categorized as follows: initial, 2 to 4 hours, 4 to 6 hours, 6 to 12 hours, and 12 to 24 hours. The primary outcome was mean time to resolution of DKA. Eighty-four patients were included in the study. The primary outcome of mean time to resolution of DKA was similar between the PL (19.74 hours) and NS (18.05 hours) groups ( = .5080). Patients treated with PL had a significantly greater rise in pH within the 4- to 6-hour and 6- to 12-hour periods. The chloride level was significantly higher and the anion gap was significantly lower for the NS group in the 6- to 12-hour period. These data suggest that the use of PL for fluid resuscitation in DKA may confer certain advantages over NS.
Fluorouracil and capecitabine are fluoropyrimidine chemotherapy agents that are commonly used for various cancers. These agents are generally well tolerated at standard doses; however, it has been reported that 31-34% of patients develop dose-limiting toxicities. Dihydropyrimidine dehydrogenase and thymidylate synthase play a major role in fluorouracil and capecitabine activity and toxicity. Uridine triacetate has shown promising results for the emergency treatment of patients who either receive an overdose of the cancer treatment fluorouracil or capecitabine or to treat patients who exhibit early-onset, severe, or life-threatening toxicity. We describe a case of a patient who developed capecitabine toxicity and was unsuccessfully treated with uridine triacetate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
