Abstract
OBJECTIVES To characterize the engagement of students enrolled in the fifth year of pharmaceutical studies in the management of the health crisis due to the COVID-19 pandemic, and to identify some determinants of this engagement during this period. METHODS With the health crisis, new missions have been entrusted during hospital internships, whereas certain internship sites were removed in hospitals and as part of the health service organization. In addition, some students who were no longer in internship returned to the hospital setting for helping in critical activities. Student engagement was studied with a questionnaire and focus groups including six or seven students in each group. RESULTS Forty-three students participated to the study. The answers to the questionnaire highlighted that they were engaged, that they usually did not wait for compensation, and that most of them were satisfied by their activity during the crisis. The thematic analysis demonstrated that despite a feeling of frustration, which was often associated with the interruption of rewarded activities, and despite a stress due to the particular context, student engagement was supported by a better consideration of the pharmacist's role as a professional in public health and by a better acknowledgement of this role by other health professionals. CONCLUSION This level of engagement is particularly encouraging because it is the witness of the ability of pharmacists to mobilize for general interest, even in adverse context.

Abstract
This study aimed to describe the contamination of sink drains (SDs) with carbapenemase-producing Enterobacterales (CPE) in three intensive care units (ICUs), and to assess the risk of transmission to hospitalized patients. All SDs were sampled monthly for CPE screening by culture. Rectal screening for CPE carriage was conducted weekly for hospitalized patients. CPE were isolated from 22% of SD samples. Some SDs remained colonized with the same strain for several months. No CPE acquisition occurred among hospitalized patients during the study. Certain strategies, such as systematic sampling of SDs in ICUs for screening for contamination by CPE, should be discouraged apart from during outbreaks.

Abstract
OBJECTIVE Staphylococcusaureus is involved in around 20% of nosocomial pneumonia cases. Vancomycin used to be the reference antibiotic in this indication, but new molecules have been commercialized, such as linezolid. Previous studies comparing vancomycin and linezolid were based on models. Comparing their real costs from a hospital perspective was needed. METHODS We performed a bicentric retrospective analysis with a cost-minimization analysis. The hospital antibiotic acquisition costs were used, as well as the laboratory test and administration costs from the health insurance cost scale. The cost of each hospital stay was evaluated using the national cost scale per diagnosis related group (DRG), and was then weighted by the stay duration. RESULTS Fifty-eight patients were included. All bacteria identified in pulmonary samples were S. aureus. The cost of nursing care per stay with linezolid was €234.10 (SD=91.50) vs. €381.70 (SD=184.70) with vancomycin (P=0.0029). The cost of laboratory tests for linezolid was €172.30 (SD=128.90) per stay vs. €330.70 (SD=198.40) for vancomycin (P=0.0005). The acquisition cost of linezolid per stay was not different from vancomycin based on the price of the generic drug (€54.92 [SD=20.54] vs. €40.30 [SD=22.70]). After weighting by the duration of stay observed, the mean cost per hospital stay was €47,411.50 for linezolid and €57,694.0 for vancomycin (NSD). CONCLUSION These results, in favor of linezolid, support other former pharmacoeconomic study based on models. The mean cost per hospitalization stay was not statistically different between the two study groups, but a trend in favor of linezolid is emerging.

Abstract
Paclitaxel-loaded lipid nanocapsules (PX-LNC) exhibit interesting in vitro characteristics with improved antitumoral activity compared with free PX formulation. Biodistribution studies were realized with the use of (14)C-trimyristin ((14)C-TM) or (14)C-phosphatidylcholine ((14)C-PC) whereas antitumoral activity of PX-LNC formulations was based on the animal survival in a chemically induced hepatocellular carcinoma (HCC) model in Wistar rats. Blood concentration-time profiles for both labeled (14)C-TM-LNC and (14)C-PC-LNC were similar; the t(1/2) and MRT values (over 2h and close to 3h, respectively, for both formulations) indicated the long circulating properties of the LNC carrier with a slow distribution and elimination phase. Survival curves of paclitaxel treated groups showed a statistical significant difference compared to the control survival curve (P=0.0036 and 0.0408). Animals treated with 4x 70 mg/m(2) of PX-LNC showed the most significant increase in mean survival times compared to the controls (IST(mean) 72%) and cases of long-term survivors were preferentially observed in the PX-LNC treated group (37.5%; 3/8). These results demonstrate the great interest to use LNC as drug delivery system for paclitaxel, permitting with an equivalent therapeutic efficiency to avoid the use of excipients such as polyoxyethylated castor oil for its formulation.

Abstract
The aim of this study was to validate a new technique for the measurement of cardiac output (CO) based on ultrasound and dilution (COUD) in anesthetized rats. A transit time ultrasound (TTU) probe was placed around the rat carotid artery, and ultrasound velocity dilution curves were generated on intravenous injections of saline. CO by COUD were calculated from the dilution curves for normal and portal hypertensive rats in which CO was known to be increased. COUD was compared with the radiolabeled microsphere method and with direct aortic TTU flowmetry for baseline CO and drug-induced CO variations. CO in direct aortic TTU flowmetry was the ascending aorta blood flow measured directly by TTU probe (normal use of TTU flowmetry). The reproducibility of COUD within the same animal was also determined under baseline conditions. COUD detected the known CO increase in portal hypertensive rats compared with normal rats. CO values by COUD were correlated with those provided by microsphere technique or direct aortic TTU flowmetry (adjusted r = 0.76, P < 10(-4) and r = 0.79, P < 0.05, respectively). Baseline CO values and terlipressin-induced CO variations were detected by COUD and the other techniques. Intra- and interobserver agreements for COUD were excellent (intraclass r = 0.99 and 0.98, respectively). COUD was reproducible at least 10 times in 20 min. COUD is an accurate and reproducible method providing low-cost, repetitive CO measurements without open-chest surgery. It can be used in rats as an alternative to the microsphere method and to direct aortic flowmetry.

Abstract
BACKGROUND/AIMS Recently, we developed a new method to measure collateral blood flow in rats: splenorenal shunt (SRS) blood flow (BF). The aims were to evaluate the reproducibility of SRSBF measurement in different models of portal hypertension, and to investigate the ability of SRSBF to disclose pharmacological changes. METHODS Hemodynamics were determined in anesthetized rats with secondary biliary, CCl4 or DMNA cirrhosis and portal vein ligation (PVL) under baseline and pharmacological (octreotide, vapreotide) conditions. The main measurements performed were: SRSBF by the transit time ultrasound (TTU) method and % portosystemic shunts (PSS) by the microsphere method. RESULTS SRSBF was 6 to 10 times higher in portal hypertensive rats and was similar in the different models of cirrhosis but was higher in portal vein ligated rats than in cirrhotic rats (1.1+/-0.7 vs 0.6+/-0.7 ml x min(-1) x 100 g(-1), p=0.01). SRSBF was correlated with mesenteric %PSS (r=0.61, p<0.01), splenic %PSS (r=0.54, p<0.05), portal pressure (r= 0.32, p<0.05) and the area of liver fibrosis (r=0.33, p<0.05). Octreotide significantly decreased SRSBF (-23+/-20%, p<0.01 vs placebo: -6+/-8%, NS). Vapreotide significantly decreased SRSBF but not mesenteric or splenic %PSS compared to placebo. The variations in SRSBF (-26+/-32%) and in splenic %PSS (0+/-15%) with vapreotide were significantly different (p<0.05) and not correlated (r=-0.1, NS). CONCLUSIONS Determination of SRSBF by TTU is an accurate way to measure collateral blood flow in different models of intra- and extra-hepatic portal hypertension in rats. Its sensitivity provides accurate measurement of pharmacological changes, unlike the traditional estimation of %PSS by the microsphere method.

Abstract
The aim of this study was to develop a technique that could serve as an index of portosystemic shunt (PSS) blood flow in portal hypertensive rats whose main shunt is the splenorenal shunt (SRS). The main hemodynamic measurements performed were: SRS blood flow by the transit-time ultrasound (TTU) method, percentage of PSS, and regional blood flows by the microsphere method. We determined the accuracy and reproducibility of SRS blood flow measurements under baseline and pharmacological (octreotide) conditions. SRS blood flow was compared with other hemodynamic characteristics. Two models of portal hypertension were used: secondary biliary and dimethylnitrosamine cirrhosis. The SRS blood flow was correlated with mesenteric (r = .76; P < .001) and splenic (r = .67; P < .01) PSS percentages. The intra- and interobserver agreements for SRS blood flow were excellent: ric = .99 and ric = .98, respectively. SRS blood flow was six times higher in portal hypertensive rats (0.6 +/- 0.7 mL . min-1 . 100 g-1) than in sham rats (0.1 +/- 0.1 mL . min-1 . 100 g-1 [P < .01]). Octreotide significantly decreased SRS blood flow but not mesenteric or splenic PSS percentages. SRS is the main PSS in rats. The measurement of SRS blood flow by TTU is accurate and reproducible. This method can be used to identify new mechanisms in hemodynamic studies that differ from those identified by the measurement of the percentage of PSS by the microsphere method, especially in pharmacological studies.

Abstract
AIMS The aim of this study was to develop a technique to measure collateral blood flow in portal hypertensive rats. METHODS Morphological techniques included inspection, casts and angiographies of portosystemic shunts. The main hemodynamic measurements were splenorenal shunt blood flow (transit time ultrasound method), percentage of portosystemic shunts and regional blood flows (microsphere method). In study 1, a model of esophageal varices was developed by ligating the splenorenal shunt. In study 2, morphological studies of the splenorenal shunt were performed in rats with portal vein ligation. In study 3, the relationship between splenorenal shunt blood flow with percentage of portosystemic shunts was evaluated in dimethylnitrosamine cirrhosis. In study 4, secondary biliary, CCl4 and dimethylnitrosamine cirrhosis were compared. In study 5, rats with portal vein ligation received acute administration of octreotide. In study 6, rats with dimethylnitrosamine cirrhosis received acute administration of vapreotide. RESULTS Blood flow of para-esophageal varices could not be measured. SRS blood flow was correlated with the mesenteric percentage of portosystemic shunts (r = 0.74, P < 0.05), splenic percentage of portosystemic shunts (r = 0.54, P < 0.05) and estimated portosystemic blood flow (r = 0.91, P < 0.01). Splenorenal shunt blood flow was 6 to 12 times higher in portal hypertensive rats, e.g., in portal vein ligated rats: 2.8 +/- 2.7 vs 0.3 +/- 0.1 mL.min-1 in sham rats (P < 0.01), and was similar in the different cirrhosis models but was higher in portal vein ligated rats than in cirrhotic rats (1.2 +/- 0.7 vs 0.6 +/- 0.6 mL.min-1.100 g-1, P = 0.05). Octreotide significantly decreased splenorenal shunt blood flow: -23 +/- 20% (P < 0.01) vs -6 +/- 8% (not significant) in placebo rats. The variation of splenorenal shunt blood flow after vapreotide was significant but not that of the splenic percentage of portosystemic shunts compared to placebo. CONCLUSIONS The splenorenal shunt is the main portosystemic shunt in rats. The measurement of splenorenal shunt blood flow is easy, accurate and reproducible and should replace the traditional measurement of the percentage of portosystemic shunts in pharmacological studies.
