Objective: To report teicoplanin-related neutropenia that developed after an episode of neutropenia induced by vancomycin therapy. Case Summary: A 57-year-old female suffered from osteomyelitis of the left humerus, with a white blood cell (WBC) count of 2.8 × 103/mm3 and absolute neutrophil count (ANC) of 0.28 × 103/mm3, occurring after 24 days of vancomycin therapy. Vancomycin was changed to teicoplanin and the agranulocytosis resolved 4 days later. However, a new episode of neutropenia, with a WBC count of 2.8 × 103/mm3 and ANC of 0.448 × 103/mm3, occurred 11 days after teicoplanin initiation. Agranulocytosis resolved 4 days following withdrawal of teicoplanin. Discussion: Because of the close time relationship between drug administration and the development of symptoms and signs, as well as between drug withdrawal and changes in WBC count and ANC, the episodes of neutropenia were suspected to be drug related. Teicoplanin-induced agranulocytosis that followed vancomycin-induced agranulocytosis suggests a possible cross-reactivity between the 2 drugs. Both reactions were categorized as probable according to the Naranjo probability scale. Conclusions: For all patients with vancomycin-induced neutropenia, possible cross-reactivity of teicoplanin should be monitored.

Published: April 2007

In humans, both clinical and functional imaging studies have evidenced the critical role played by the posterior parietal cortex, and particularly by the anterior intraparietal area (AIP), in skilled hand movements. However, the exact contribution of AIP to precision grasping remains debated. Here we used transcranial magnetic stimulation (TMS) to induce virtual lesions of the left and/or right AIP in subjects performing a grip-lift task with either hand.We found that, during movement preparation, a virtual lesion of AIP had distinct consequences on precision grasping of either hand depending on its time of occurrence: TMS applied 270–220 ms before the fingers contacted the manipulandum altered specifically the hand shaping, whereas lesions induced 170–120 ms before contact time only affected the grip force scaling. The lateralization of these two processes in AIP is also strikingly different: whereas a bilateral lesion of AIP was necessary to impair hand shaping, only a unilateral lesion of the left AIP altered the grip force scaling in either hand.The present study shows that, during movement preparation, AIP is responsible for processing two distinct, temporally dissociated, precision grasping parameters, regardless of the hand in use. This indicates that the contribution of AIP to hand movements is “effector- independent,” a finding that may explain the invariance of grasping movements performed with either hand.

Stochastic Controllability of Linear Systems With State DelaysA class of finite-dimensional stationary dynamic control systems described by linear stochastic ordinary differential state equations with a single point delay in the state variables is considered. Using a theorem and methods adopted directly from deterministic controllability problems, necessary and sufficient conditions for various kinds of stochastic relative controllability are formulated and proved. It will be demonstrated that under suitable assumptions the relative controllability of an associated deterministic linear dynamic system is equivalent to the stochastic relative exact controllability and the stochastic relative approximate controllability of the original linear stochastic dynamic system. Some remarks and comments on the existing results for the controllability of linear dynamic systems with delays are also presented. Finally, a minimum energy control problem for a stochastic dynamic system is formulated and solved.
Equivalence and Reduction of Delay-Differential Systems
Authors: Boudellioua Mohamed 
Published: April 2007

Equivalence and Reduction of Delay-Differential SystemsA new direct method is presented which reduces a given high-order representation of a control system with delays to a first-order form that is encountered in the study of neutral delay-differential systems. Using the polynomial system description (PMD) setting due to Rosenbrock, it is shown that the transformation connecting the original PMD with the first-order form is Fuhrmann's strict system equivalence. This type of system equivalence leaves the transfer function and other relevant structural properties of the original system invariant.

Published: April 2007

A New Fuzzy Lyapunov Approach to Non-Quadratic Stabilization of Takagi-Sugeno Fuzzy ModelsIn this paper, new non-quadratic stability conditions are derived based on the parallel distributed compensation scheme to stabilize Takagi-Sugeno (T-S) fuzzy systems. We use a non-quadratic Lyapunov function as a fuzzy mixture of multiple quadratic Lyapunov functions. The quadratic Lyapunov functions share the same membership functions with the T-S fuzzy model. The stability conditions we propose are less conservative and stabilize also fuzzy systems which do not admit a quadratic stabilization. The proposed approach is based on two assumptions. The first one relates to a proportional relation between multiple Lyapunov functions and the second one considers an upper bound to the time derivative of the premise membership functions. To illustrate the advantages of our proposal, four examples are given.
Application of Bearing and Distance Trees to the Identification of Landmarks on the Coast
Authors: Praczyk Tomasz 
Published: April 2007

Application of Bearing and Distance Trees to the Identification of Landmarks on the CoastThe problem of continuous position availability is one of the most important issues connected with the human activity at sea. Because the availability of satellite navigational systems can be limited in some cases, e.g. during military operations, one has to consider additional methods of acquiring information about the ship's position. In this paper one of these methods is presented, which is based on exploiting landmarks located on a coastline. A navigational radar is used to obtain information about these points. In order to estimate the ship's position by means of a set of landmarks, it is necessary to know their accurate locations. The paper presents a landmark identification method based on the comparison of bearing and distance trees representing pattern points generated from a chart, as well as points extracted from a radar image.

A Federated Approach to Parallel and Distributed Simulation of Complex SystemsThe paper describes a Java-based framework called ASimJava that can be used to develop parallel and distributed simulators of complex real-life systems. Some important issues associated with the implementation of parallel and distributed simulations are discussed. Two principal paradigms for constructing simulations today are considered. Particular attention is paid to an approach for federating parallel and distributed simulators. We describe the design, performance and applications of the ASimJava framework. Two practical examples, namely, a simple manufacturing system and computer network simulations are provided to illustrate the effectiveness and range of applications of the presented software tool.
Data Probes, Vertical Trajectories and Classification: A Tentative Study
Authors: Pearson David 
Published: April 2007

Data Probes, Vertical Trajectories and Classification: A Tentative StudyIn this paper we introduce a method of classification based on data probes. Data points are considered as point masses in space and a probe is simply a particle that is launched into the space. As the probe passes by data clusters, its trajectory will be influenced by the point masses. We use this information to help us to find vertical trajectories. These are trajectories in the input space that are mapped onto the same value in the output space and correspond to the data classes.
A Proposition of Mobile Fractal Image Decompression
Authors: Nikiel Sławomir 
Published: April 2007

A Proposition of Mobile Fractal Image DecompressionMultimedia are becoming one of the most important elements of the user interface with regard to the acceptance of modern mobile devices. The multimodal content that is delivered and available for a wide range of mobile telephony terminals is indispensable to bind users to a system and its services. Currently available mobile devices are equipped with multimedia capabilities and decent processing power and storage area. The most crucial factors are then the bandwidth and costs of media transfer. This is particularly visible in mobile gaming, where textures represent the bulk of binary data to be acquired from the content provider. Image textures have traditionally added visual realism to computer graphics. The realism increases with the resolution of textures. This represents a challenge to the limited bandwidth of mobile-oriented systems. The challenge is even more obvious in mobile gaming, where single image depicts a collection of shots or animation cycles for sprites and a backdrop scenery. In order to increase the efficiency of image and image texture transfer, a fractal based compression scheme is proposed. The main idea is to use an asymmetric server-client architecture. The resource demanding compression process is performed on the server side while the client part decompresses highly packed image data. The method offers a very high compression ratio for pictures representing image textures for natural scenes. It aims to minimize the transmission bandwidth that should speed up the downloading process and minimize the cost and time of data transfer. The paper focuses on the implementation of fractal decompression schemes suitable for most mobile devices, and opens a discussion on fractal image models for limited resource applications.

Published: April 2007

Abstract
This investigation of Pomeranian Bay waters was conducted from March 2001 to August of 2003 from aboard the r/v Nawigator XXI, which is owned by the Maritime Academy in Szczecin. A total of 147 water samples were collected at 15 stations on three transects in the Pomeranian Bay from Świnoujście, Międzyzdroje, and Dziwnów to the Odra Bank. Zooplankton was sampled with a Bongo type planktonometer Ø = 20 cm with a mesh size of 80 μm during 10 min. filtering hauls in the pelagic zone from the bottom to the surface at an average vessel speed of 3 - 4 knots. The method developed and published by Orłowski was used to transform the large amount of seasonal data for the entire study period into isoline illustrations of the spatial structures in the Pomeranian Bay of mesozooplankton and selected species, namely Acartia bifilosa, Acartia longiremis, Pseudocalanus elongatus, and Temora longicornis. The average mesozooplankton aggregations in ten consecutive seasons at the 15 stations investigated from 2001 to 2003 in the entire Odra estuary area fluctuated from 2,442 to 92,200 ind. m-3. The highest species variety was noted among marine Copepoda, which was the dominant group in virtually every season investigated. Their maximum abundance reached as much as 213,493 ind. m-3. The euryhaline species A. bifilosa occurred throughout the research period and at all stations at an abundance that reached 210,443 ind. m-3. The seasonal succession series were as follows: in spring, the dominants were Acartia spp. and Evadne nordmanni; in summer - Keratella cochlearis, Bosmina coregoni maritima, and A. bifilosa; in fall - T. longicornis and Acartia spp.; in winter - T. longicornis and Centropages hamatus.
Microbiological changes in the environment caused by deep dredging. A case study: post-dredging pit Kuźnica II (Puck Bay)
Authors: Graca Bożena , Dudkowiak Maria 
Published: April 2007

Abstract
In this study psychrophilic, mesophilic and denitrifying bacterial abundances were studied seasonally (summer, autumn, winter and spring) in the water column and surface sediment layer (0-5 cm) in the post dredging pit Kuźnica II and natural areas of Puck Bay. The research was conducted between VI 2001 and III 2003.
In the pit area an increase in mesophilic bacteria and a decrease in denitrifying bacteria numbers were observed, when compared to the natural areas. In the case of the mesophilic bacteria, the increase was visible in the near-bottom waters and surficial sediments during the period of well developed vegetation - in summer and autumn. In the case of denitrifying bacteria, the decrease of number concerned the sediments. Numbers of psychrophilic bacteria in both the natural and dredged areas did not differ significantly over the course of the study.
These results suggest that deep dredging can cause the self-purification potential of the ecosystem to be diminished and induce strong bacteriological pollution.
Sulfur Cycling and the Sulfurization of Humic and Fulvic Acids in the Sediments of the rivers Rupel (Belgium) and Authie (northern France)
Authors: Lojen Sonja , Čermelj Branko , Wartel Michel 
Published: April 2007

Abstract
Sulfur cycling and the sulfurization of humic and fulvic acids were compared in recent sediments from two western European rivers (the heavily polluted River Rupel in Belgium and the pristine River Authie in northern France). The sulfurization of humic and fulvic substrates occurs in both sediments irrespective of organic loading, but the sulfur species added to the organic substrate differ. Some sulphurization of fulvic acid by oxidized S was observed in the strongly reducing sediment of the River Rupel. Humic acids were sulfurized in the sediments of both rivers in these segments with prevailing reducing conditions by reduced S.
The transport and distribution of the river load from the Reda River into the Puck Lagoon (southern Baltic Sea, Poland)
Authors: Szymczak Ewa , Piekarek-Jankowska Halina 
Published: April 2007

Abstract
The main aim of this study was to determine the size of the load carried by the Reda River that was discharged into the sea and the load distribution on the bottom of the Puck Lagoon. Water exchange with the open sea was limited in this shallow reservoir where the average depth was 3.13 m. The input of material was dominated by river transport, whereas abrasion and aeolian processes were insignificant in the total sediment inflow. The Reda River, one of the main rivers flowing into the lagoon, is 44.9 km long and has a catchment area of 485.2 km2. The investigations were conducted between 2001 and 2004 at the Mrzezino hydrological cross-section and at the river mouth in the Puck Lagoon.
The study demonstrated that the Reda River discharged annually approximately 9,900 tons of sediments into the Puck Lagoon, 73% of which was the bed load that in the final course of the river created an underwater accumulation form. The granulometric composition of the deltaic deposits, similar to the bed load, was dominated by coarse-grained sand fractions. The proportion of the aleurolite and pelite fraction was insignificant at less than 1%. The suspended sediment was composed of particles that ranged in size from 0.00045 mm to 0.25 m. Mineral particles were more common than organic ones in the load discharged by the Reda River into the Puck Lagoon and constituted 99% of the bed load.

ImportanceDelayed autotransplantation of cryopreserved parathyroid tissue (DACP) is the only surgical treatment for permanent postoperative hypoparathyroidism. Studies suggest that only a small minority of cryopreserved samples are ultimately autotransplanted with highly variable outcomes. For these reasons, many have questioned the economic utility of the process, although, to the authors’ knowledge, this has never been formally studied.ObjectiveTo report the clinical outcomes of parathyroid cryopreservation and DACP at a large academic institution and to determine the cost-effectiveness of this treatment.Design, Setting, and ParticipantsAn institutional review board–approved, retrospective review of patients at a single institution who underwent DACP over a 17-year period was conducted with a median follow-up of 48.2 months. A forward-looking cost-utility analysis was then performed to determine the economic utility of cryopreservation/DACP vs usual care (monitoring and supplementation). Patients who had parathyroid tissue in cryopreserved storage between August 2005 to September 2022 at a single-center, academic, quaternary care center were identified.ExposureParathyroid cryopreservation and DACP.Main Outcomes and MeasuresGraft functionality, clinical outcomes, and cost utility using a willingness-to-pay threshold of $100 000 per quality-adjusted life-year (QALY).ResultsA total of 591 patients underwent cryopreservation. Of these, 10 patients (1.7%; mean [SD] age, 45.6 [17.9] years; 6 male [60%]) underwent DACP. A minority of autografts (2 [20%]) were subsequently fully functional, one-half (5 [50%]) were partially functional, and 3 (30%) were not functional. The cost-utility model estimated that at a large academic center over 10 years, the additional cost of 591 patients undergoing cryopreservation and 10 patients undergoing autotransplantation would be $618 791.64 (2022 dollars) and would add 8.75 QALYs, resulting in a cost per marginal QALY of $70 719.04, which is less than the common willingness-to-pay threshold of $100 000/QALY.Conclusions and RelevanceThe reimplantation rate of cryopreserved tissue was low (&amp;lt;2%), but when implanted, autografts were at least partially functional 70% of the time. In the first-ever, to the authors’ knowledge, formal cost analysis for this treatment, results of the current model suggest that cryopreservation and autotransplantation were cost-effective compared with the usual care for hypoparathyroidism at a large, academic institution. It is recommended that each surgical center consider whether the economic and logistical commitments necessary for cryopreservation are worthwhile for their individual needs.

ImportanceSurgical site infections (SSIs)—especially anastomotic dehiscence—are major contributors to morbidity and mortality after rectal resection. The role of mechanical and oral antibiotics bowel preparation (MOABP) in preventing complications of rectal resection is currently disputed.ObjectiveTo assess whether MOABP reduces overall complications and SSIs after elective rectal resection compared with mechanical bowel preparation (MBP) plus placebo.Design, Setting, and ParticipantsThis multicenter, double-blind, placebo-controlled randomized clinical trial was conducted at 3 university hospitals in Finland between March 18, 2020, and October 10, 2022. Patients aged 18 years and older undergoing elective resection with primary anastomosis of a rectal tumor 15 cm or less from the anal verge on magnetic resonance imaging were eligible for inclusion. Outcomes were analyzed using a modified intention-to-treat principle, which included all patients who were randomly allocated to and underwent elective rectal resection with an anastomosis.InterventionsPatients were stratified according to tumor distance from the anal verge and neoadjuvant treatment given and randomized in a 1:1 ratio to receive MOABP with an oral regimen of neomycin and metronidazole (n = 277) or MBP plus matching placebo tablets (n = 288). All study medications were taken the day before surgery, and all patients received intravenous antibiotics approximately 30 minutes before surgery.Main Outcomes and MeasuresThe primary outcome was overall cumulative postoperative complications measured using the Comprehensive Complication Index. Key secondary outcomes were SSI and anastomotic dehiscence within 30 days after surgery.ResultsIn all, 565 patients were included in the analysis, with 288 in the MBP plus placebo group (median [IQR] age, 69 [62-74] years; 190 males [66.0%]) and 277 in the MOABP group (median [IQR] age, 70 [62-75] years; 158 males [57.0%]). Patients in the MOABP group experienced fewer overall postoperative complications (median [IQR] Comprehensive Complication Index, 0 [0-8.66] vs 8.66 [0-20.92]; Wilcoxon effect size, 0.146; P &amp;lt; .001), fewer SSIs (23 patients [8.3%] vs 48 patients [16.7%]; odds ratio, 0.45 [95% CI, 0.27-0.77]), and fewer anastomotic dehiscences (16 patients [5.8%] vs 39 patients [13.5%]; odds ratio, 0.39 [95% CI, 0.21-0.72]) compared with patients in the MBP plus placebo group.Conclusions and RelevanceFindings of this randomized clinical trial indicate that MOABP reduced overall postoperative complications as well as rates of SSIs and anastomotic dehiscences in patients undergoing elective rectal resection compared with MBP plus placebo. Based on these findings, MOABP should be considered as standard treatment in patients undergoing elective rectal resection.Trial RegistrationClinicalTrials.gov Identifier: NCT04281667
