Pharmaceutical care in an inpatient pediatric intensive care unit: an international multicentric study

Introduction Pediatric intensive care patient represent a population athigh risk for drug-related problems. Our objective is to describe drugrelated problems and intervention of four decentralized pharmacists inpediatric and cardiac intensive care unit.Materials & Methods Multicentric, descriptive and prospectivestudy over a six-month period (August 1st 2009-January 31st 2010).Drug-related problems and clinical interventions were compiled infour pediatric centers using a tool developed by the Socie´te´ Franc¸aisede Pharmacie Clinique. Data concerning patients, drugs, intervention,documentation, approval (if needed), and estimated impact werecompiled. The four pharmacists participating were from Belgium (B),France (F), Quebec (Q) and Switzerland (S).Results A total of 996 interventions were collected: 129 (13%) in B,238 (24%) in F, 278 (28%) in Q and 351 (35%) in S. These interventionstargeted 269 patients (median 22 month-old, 52% male): 69(26%) in B, 88 (33%) in F, 56 (21%) in Q and in S. These data werecollected during 28 non consecutive days in the clinical unit in B, 59days in F, 42 days in Q and 63 days in S. The main drug-relatedproblems were inappropriate administration technique (293, 29%),untreated indication (254, 25%) and supra therapeutic dosage (106,11%). The pharmacist's interventions concerned mainly administrationmode optimization (223, 22%), dose adjustment (200, 20%) andtherapeutic monitoring (164, 16%). The three major drug classesleading to interventions were anti-infectives for systemic use (233,23%) and alimentary tract and metabolism drugs (218, 22%). Interventionsconcerned mainly residents and all clinical staff (209, 21%).Among the 879 (88%) interventions requiring a physician's approval,731 (83%) were accepted. Interventions were considered as having amoderate (51%) or major (17%) clinical impact. Among the interventionsprovided, 10% were considered to have an economicalpositive impact. Differences and similarities between countries willbe presented at the poster session.Discussion & Conclusion Decentralized pharmacist at patient bedsideis a pre-requisite for pharmaceutical care. There are limitedstudies comparing the activity of clinical pharmacists betweencountries. This descriptive study illustrates the ability of clinicalpharmacist to identify and solve drug-related problems in pediatricintensive care unit in four different francophone countries.

Kinetic study of neuropeptide Y (NPY) proteolysis in blood and identification of NPY3-35: a new peptide generated by plasma kallikrein.

There is little information on how neuropeptide Y (NPY) proteolysis by peptidases occurs in serum, in part because reliable techniques are lacking to distinguish different NPY immunoreactive forms and also because the factors affecting the expression of these enzymes have been poorly studied. In the present study, LC-MS/MS was used to identify and quantify NPY fragments resulting from peptidolytic cleavage of NPY(1-36) upon incubation with human serum. Kinetic studies indicated that NPY(1-36) is rapidly cleaved in serum into 3 main fragments with the following order of efficacy: NPY(3-36) >> NPY(3-35) > NPY(2-36). Trace amounts of additional NPY forms were identified by accurate mass spectrometry. Specific inhibitors of dipeptidyl peptidase IV, kallikrein, and aminopeptidase P prevented the production of NPY(3-36), NPY(3-35), and NPY(2-36), respectively. Plasma kallikrein at physiological concentrations converted NPY(3-36) into NPY(3-35). Receptor binding assays revealed that NPY(3-35) is unable to bind to NPY Y1, Y2, and Y5 receptors; thus NPY(3-35) may represent the major metabolic clearance product of the Y2/Y5 agonist, NPY(3-36).

Long maximal incremental tests accurately assess aerobic fitness in class II and III obese men.

This study aimed to compare two different maximal incremental tests with different time durations [a maximal incremental ramp test with a short time duration (8-12 min) (STest) and a maximal incremental test with a longer time duration (20-25 min) (LTest)] to investigate whether an LTest accurately assesses aerobic fitness in class II and III obese men. Twenty obese men (BMI≥35 kg.m-2) without secondary pathologies (mean±SE; 36.7±1.9 yr; 41.8±0.7 kg*m-2) completed an STest (warm-up: 40 W; increment: 20 W*min-1) and an LTest [warm-up: 20% of the peak power output (PPO) reached during the STest; increment: 10% PPO every 5 min until 70% PPO was reached or until the respiratory exchange ratio reached 1.0, followed by 15 W.min-1 until exhaustion] on a cycle-ergometer to assess the peak oxygen uptake [Formula: see text] and peak heart rate (HRpeak) of each test. There were no significant differences in [Formula: see text] (STest: 3.1±0.1 L*min-1; LTest: 3.0±0.1 L*min-1) and HRpeak (STest: 174±4 bpm; LTest: 173±4 bpm) between the two tests. Bland-Altman plot analyses showed good agreement and Pearson product-moment and intra-class correlation coefficients showed a strong correlation between [Formula: see text] (r=0.81 for both; p≤0.001) and HRpeak (r=0.95 for both; p≤0.001) during both tests. [Formula: see text] and HRpeak assessments were not compromised by test duration in class II and III obese men. Therefore, we suggest that the LTest is a feasible test that accurately assesses aerobic fitness and may allow for the exercise intensity prescription and individualization that will lead to improved therapeutic approaches in treating obesity and severe obesity.
