Front-crawl instantaneous velocity estimation using a wearable inertial measurement unit.

Monitoring the performance is a crucial task for elite sports during both training and competition. Velocity is the key parameter of performance in swimming, but swimming performance evaluation remains immature due to the complexities of measurements in water. The purpose of this study is to use a single inertial measurement unit (IMU) to estimate front crawl velocity. Thirty swimmers, equipped with an IMU on the sacrum, each performed four different velocity trials of 25 m in ascending order. A tethered speedometer was used as the velocity measurement reference. Deployment of biomechanical constraints of front crawl locomotion and change detection framework on acceleration signal paved the way for a drift-free integration of forward acceleration using IMU to estimate the swimmers velocity. A difference of 0.6 ± 5.4 cm · s(-1) on mean cycle velocity and an RMS difference of 11.3 cm · s(-1) in instantaneous velocity estimation were observed between IMU and the reference. The most important contribution of the study is a new practical tool for objective evaluation of swimming performance. A single body-worn IMU provides timely feedback for coaches and sport scientists without any complicated setup or restraining the swimmer's natural technique.

Prospective monitoring of cefepime in intensive care unit adult patients

Rapport de synthèse :Le céfépime a été associé à un taux de mortalité supérieur à celui des autres bêta-lactamines chez les patients traités pour un sepsis sévère. Une des hypothèses avancées pour expliquer ces échecs thérapeutiques sont de possibles effets secondaires cachés (par ex. neurologiques) ou des paramètres pharmacocinétiques/pharmacodynamiques (PK/PD) inadaptés. Le présent travail a étudié cette problématique en mesurant prospectivement la pharmacocinétique du céfépime chez 21 patients consécutifs hospitalisés aux soins intensifs adultes (SIAD) pour une pneumonie nosocomiale. La population étudiée avec un âge médian 55,1 ans, a reçu par voie intraveineuse du céfépime à raison de 2 g toutes les 12 heures pour une clairance de la créatinine (Clcr)>50 mI/ min, et 2 g toutes les 24 heures ou 36 heures pour une Clcr<50 ml /min. Les taux plasmatiques de céfépime ont été mesurés à plusieurs reprises avant et après administration du médicament après la lèoe dose et à l'état d'équilibre par chromatographie en phase liquide à haute pression. Les taux plasmatiques ont considérablement varié entre les patients. Cent pour cent (21/21) des patients ont eu une durée appropriée d'antibiothérapie avec des taux plasmatiques supérieures à la CMI du céfépime (T>CMI>50%) pour les agents pathogènes retrouvés dans cette étude (CMI<4 mg/I), mais seulement 45-65% d'entre eux ont eu une couverture appropriée pour les agents pathogènes potentiels présentant une CMI> 8 mg/I pour le céfépime. Deux patients avec une insuffisance rénale (Clcr<30 ml/min) ont présenté des symptômes compatibles avec une épilepsie non-convulsive (état confusionnel et myoclonies) attribuée dans un 2ème temps à une toxicité du céfépime après que les taux plasmatiques aient été communiqués aux soignants qui ont suspendu l'antibiothérapie avec disparition des symptômes. Les résultats de cette étude empirique confirment l'existence d'effets secondaires cachés et de paramètres PK/PD inappropriés (pour les agents pathogènes ayant des CMI de limite supérieure) dans notre population de SIAD. En outre, ils mettent en évidence une fenêtre thérapeutique efficace pour une posologie de céfépime de 2 g toutes les 12 heures chez les patients ayant une Clcr>50 ml/min infectés par des pathogènes avec des CMI pour le céfépime <4 mg/I. Les échecs thérapeutiques constatés dans cette étude sont probablement liés à des taux sériques inadaptés, résultant de la difficulté de prescription dans les situations cliniques complexes. Dans ce contexte, un prompt dosage plasmatique du céfépime doit être considéré en cas de diminution de la Clcr ou en présence de CMI élevées.

Construct validity of the French version of the PRWE (Patient Rated Wrist Evaluation) with the French version of the DASH (Disabilities Arm Shoulder and Hand) is good to very good in a population of patients with wrist injuries in an inpatient rehabilitation unit

Objective.- The Patient-Rated Wrist Evaluation is a specific questionnaire for the wrist [1]. It consists of 15 questions with a total score of 100. It was recently translated into French [2]. However, its validity has not been tested in this language. The Disabilities Arm Shoulder and Hand (DASH), with well-established psychometric properties, is considered as the reference questionnaire for the evaluation of upper extremities. The objective of this study is to measure the construct validity of the PRWE-F with the DASH-F in patients with wrist pathology.Patients and methods.- Fifty-one patients (40 m, 11 w, mean age 42 years), 25 fractures of the radius and 26 lesions of the carpus.Questionnaires PRWE-F and DASH-F at entry and at discharge (0 to 100). Calculation of the construct validity of the PRWE-F comparing with the DASH-F with Pearson correlation coefficients (r) at entry and at discharge. Level of significance (alpha) was set at 5%.Results.- Correlation DASH/PRWE at entry: r = 0.799 (95% CI 0.671 to 0.881), P < 0.0001. Correlation DASH/PRWE at discharge: r = 0.847 (95% CI: 0.745 to 0.910), P < 0.0001.Discussion.- The construct validity of the two instruments indicates that they measure the same concept. Our correlation between DASH-F and PRWE-F, going from 0.799 to 0.847, are comparable to those published in different languages (0.71 to 0.84) [3,4]. The questionnaires PRWE-F can thus be used in rehabilitation patients presenting with wrist pathologies; it is comparable to the DASH but described by MacDermid [1] to be more specific. Compared to the DASH it has the advantage of consisting of two dimensions. Its construct validity is excellent. This questionnaire should be evaluated in other populations, and it should be compared with hand questionnaires more specific than the DASH.

Level shifts in a panel data based unit root test : an application to the rate of unemployment

Several unit root tests in panel data have recently been proposed. The test developed by Harris and Tzavalis (1999 JoE) performs particularly well when the time dimension is moderate in relation to the cross-section dimension. However, in common with the traditional tests designed for the unidimensional case, it was found to perform poorly when there is a structural break in the time series under the alternative. Here we derive the asymptotic distribution of the test allowing for a shift in the mean, and assess the small sample performance. We apply this new test to show how the hypothesis of (perfect) hysteresis in Spanish unemployment is rejected in favour of the alternative of the natural unemployment rate, when the possibility of a change in the latter is considered.

An analysis of inflation rates in the European Union using wavelets : strong evidence against unit roots

In this paper we assume inflation rates in European Union countries may in fact be fractionally integrated. Given this assumption, we obtain estimations of the order of integration by means a method based on wavelets coefficients. Finally, results obtained allow reject the unit root hypothesis on inflation rates. It means that a random shock on the rate of inflation in these countries has transitory effects that gradually diminish with the passage of time, that this, said shock hasn¿t a permanent effect on future values of inflation rates

New evidence of the real interest rate parity for OECD countries using panel unit root tests with breaks

This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence of multiple structural breaks. Our results strongly support the fulfilment of the weak version of the RIRP for the studied period once dependence and structural breaks are accounted for.

Delirium in elderly patients hospitalized in an acute care unit.

Introduction: Delirium is frequent in hospitalized older people, with incidence rate up to 40% in acute care. Delirium is associated with several adverse consequences, including increased mortality and institutionalization. This study aims to investigate the prevalence, incidence, and consequences of delirium in patients hospitalized in an acute care unit for elderly (ACE unit). Methods: Over a 3 months period, every patient (N = 93, mean age 84.1 ± 7.8 years, 66/93(71%) women) admitted to a 28-bed ACE unit were systematically assessed for delirium. Trained nurses used the Confusion Assessment Method (CAM) instrument to determine the presence of delirium at admission and on each subsequent day over patients' stay. Delirium prevalence rate was defined as the proportion of patients with a positive CAM within 24 hours of admission to the ACE unit. Delirium incidence rate was defined as the proportion of patients with a negative CAM at admission whose CAM became positive at least once during their stay. This evaluation was part of a functional assessment, including Basic Activities of Daily Life (Katz BADL, from 0 to 6, higher score indicating better function). Delirium prevention interventions and specific treatment was provided if needed. Results: Overall,25/93(27%)patients had delirium during their stay. Prevalence of delirium at admission was 10/93 (11%), with an incidence of 15/83(18%). Compared with non-delirious patients, those with delirium were more frequently men (10/25(40%) vs 17/68(25%), p <.001) and had reduced functional status at admission(BADL 2.0 ± 1.9 vs 3.6 ± 2.1, p = .004). They tended to be older (86.0 ± 6.7 vs 83.3 ± 8.1 years, p = .110). At discharge, delirium was associated with reduced functional status (BADL 2.0 ± 2.1 vs 4.3 ± 1.9, p <.001), lower rate of home discharge (6/20(30%) vs 28/65 (43%), p = .009) and increased mortality (5/25 (20%) vs 3/68 (5%), p <.001). On average, patients with delirium stayed 5.7 days longer (17.0 ± 9.8 vs 11.31 ± 6.3, p = .011). Conclusion: Delirium occurred in almost a third of these older patients, even though its incidence was relatively low in this frail population. Despite specific management, delirium remained associated with higher risk for adverse outcomes at discharge. These results suggest that early preventive interventions, implemented as soon as possible after hospital admission, might be needed in similar population to achieve better outcomes. Effectiveness of such interventions will be evaluated in future studies.

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.
