[Nurse-led central venous catheter insertion, a review of a cooperation protocol]. / Pose de voie veineuse centrale par l'infirmier, retour sur un protocole de coopération.

Chemotherapy for cancer patients often requires a central venous catheter the insertion of which has previously been the exclusive remit of medics. As the shortage of doctors worsens, waiting times for catheter placement have increased. The implementation of the 'Transfer of competence: nurse-led central venous catheter insertion' cooperation protocol in 2016, in the Paris hospital trust (AP-HP), has enabled these waiting times to be reduced without any increase in the frequency of complications or effects on the safety of the procedure.

Optimization of the arsenazo-III method for the determination of uranium in water and plant samples.

This work reports a reliable, fast and optimized photometric technique based on the specific chemical complexation of uranyl ion with arsenazo-III. In the case of solid samples (plant samples), for which mineralization under acidic and oxidative conditions was used, addition of ascorbic acid led to stabilization of the arsenazo-uranyl complex over time. The results, in total agreement with data obtained from α and γ spectrometries, demonstrate that the present technique is able to precisely quantify uranium in water as well as in plant samples, within the µg/L and mg/g ranges respectively.

Real time identification of drug-induced liver injury (DILI) through daily screening of ALT results: a prospective pilot cohort study.

OBJECTIVE: Identification of drug-induced liver disease (DILI) is difficult, even among hospitalized patients. The aim of this pilot study was to assess the impact of a specific strategy for DILI screening. DESIGN: We prospectively compared the number of acute DILI cases identified in one week of a proactive strategy based on centralized elevated ALT values to those identified with a standard of care strategy for 24-week period based on referral cases to the hepatology unit. In the centralized strategy, a designated study biochemist identified patients with ALT greater than 3 times the upper limit of normal values (ULN) and notified the designated hepatologists, who then went to the patients' wards, analyzed the charts, and if necessary, interviewed the identified patients. During these two periods, patients with possible DILI were included after signing an informed consent in an ongoing European diagnostic study (SAFE-T consortium). RESULTS: During the 24-week period of the standard strategy, 12 (0.04%) patients out of a total of 28,145 were identified as having possible DILI, and 11 of these accepted to be included in the protocol. During the one-week proactive period, 7 patients out of a total of 1407 inpatients (0.498%) [odds ratio vs. standard = 12.1 (95% CI, 3.9-32.3); P<0.0001] were identified with possible DILI, and 5 were included in the protocol. CONCLUSION: A simple strategy based on the daily analysis of cases with ALT >3 ULN by designated biochemists and hepatologists identified 12 times more acute cases of drug-induced liver disease than the standard strategy. This pilot cohort is registered on the number AP-HP P110201/1/08-03-2011 and AFSSAPS B110346-70.
