Abstract
OBJECTIVES Cytomegalovirus (CMV) is the most common infectious cause of congenital malformations. CMV infections are frequently symptomatic in case of a primary infection during pregnancy. Generally, maternal immunity protects the newborn against a symptomatic course of the CMV infection. METHODS We present clinical information and medical images of a neonate with non-primary congenital CMV infection. RESULTS We report the case of a severe congenital infection in a newborn clinically presenting with diffuse petechia, facial dysmorphisms, respiratory distress, hepatomegaly and hypotonia. The girl was born to a mother with CMV immunity. Blood results demonstrated thrombocytopenia and elevated transaminases. Brain MRI revealed ventricular dilatation and germinolytic cysts, compatible with CMV infection. Auditory brain stem response testing was abnormal. CMV culture of saliva was positive. This led to the diagnosis of a severe congenital CMV infection due to a non-primary maternal infection. Antiviral treatment with valganciclovir was initiated immediately and continued for 6 months. CONCLUSION Our case illustrates that, even when the mother was demonstrated CMV immune, congenital CMV infection is still an important differential diagnostic consideration in neonates presenting with congenital cerebral abnormalities, thrombocytopenia and/or hearing loss.

Abstract
Abstract
Background
Effective integrated care interventions for hypertension (HT) and type 2 diabetes (T2D) exist and need to be scaled-up. The ‘SCale-Up diaBetes and hYpertension care' SCUBY project aims to facilitate scale-up of integrated care for HT and T2D through the implementation of contextualised scale-up roadmaps in Cambodia, Slovenia and Belgium and co-creation in policy dialogues. We herewith describe the plan for the process and scale-up evaluation of the SCUBY project, including the development, adoption and implementation of the roadmaps. The specific goals of the process evaluation are to (i) analyse how the reality of scale-up adheres to the developed roadmaps and (ii) assess how the different contexts can influence the implementation process of the scale-up strategies.
Methods
A comprehensive framework was developed to include context, process, scale-up and impact evaluation that is embedded in implementation and political theory. A diverse range of mostly qualitative tools - including a policy dialogue reporting form, a stakeholder follow-up interview and survey, project diaries and policy mapping - will be used to assess how stakeholders perceive the scale-up implementation process and adaptations to the roadmap. Key implementation outcomes include acceptability, feasibility relevance, adaptation, adoption and cost of roadmap activities. The role of context is relevant, and barriers and facilitators to scale-up will be continuously assessed.
Conclusions
The SCUBY project presents a comprehensive framework to guide the evaluation of scale-up of complex interventions. We describe three contextualised roadmaps, for Belgium, Slovenia and Cambodia, each adopting their own (horizontal/diversification/vertical) scale-up strategy(ies) as a basis to monitor adaptations through a co-creation process. This study protocol will be a guide for other scale-up interventions making use of knowledge translation and co-creation activities.
Key messages
Process evaluation is needed to keep track of complex interventions including scale up. The SCUBY project developed an evaluation plan to comprehensively monitor the scale-up of HT and T2D care.

Abstract
Abstract
Introduction
Chronic diseases form the largest burden of disease in European countries. Redesign of health systems towards chronic integrated care is needed, with more collaboration between first and second line, between medical and social services and support to prevention and self-management. What are the levers for change in such health systems? This study addresses this knowledge gap, through a policy analysis of barriers and facilitators for change towards chronic integrated care.
Methods
26 central level stakeholders were selected, based upon their influence in regulation and policy, financing, health care provision and community representation. Semi-structured face-to-face interviews were held covering assessment of past and current policies and implementation, barriers and opportunities for change.
Results
Reforms have taken place, such as the stimulation of local initiatives for chronic integrated care projects and the set-up of local care councils. Most stakeholders assessed the current Belgium's implementation of integrated care as low, despite a growing awareness for the need for change. A context factor often mentioned to constrain implementation was a state reform which led to a partial decentralization, fragmentation of decision power and a division of healthcare competences between federal and federated levels. Other barriers were the current financing system, the lack of investments in new models of care and the vested interests of providers.
Discussion
This analysis shows that chronic care reform in Belgium is constrained by partial decentralization of primary health care, and by the financing system and vested interests. It points to the need for coordination of health policy making and implementation. Disentangling the levels of decision-making and the financial leverage at these levels gives insights for change and change management, for the Belgium health system and other countries with a strong decentralized system.
Key messages
The current Belgium’s implementation of integrated care was assessed as low, due to different contexts factors such as division of health care competencies between different governmental levels. In a country as Belgium with a strong decentralized health care system coordination of health policy making and implementation is key in order to scale up integrated care for chronic diseases.

Abstract
Background: Although psychoactive substance use disorders (PSUDs) are a domain of mental health, addiction psychiatry is only formally recognized as a subspecialty in a few European countries, and there is no standardized training curriculum. Methods: A 76-item questionnaire was developed and disseminated through an online anonymous data-collecting system and hand-to-hand amongst psychiatric trainees from the 47 European countries of the Council of Europe plus Israel and Belarus. Results: 1,049/1,118 psychiatric trainees from 30 European countries completed the questionnaire. Fifty-nine-point nine percent of trainees stated to have training in addictions. Amongst the trainees who described having training in addictions, 43% documented a not well-structured training and 37% an unsatisfactory training, mainly due to poor acquired knowledge. Overall, 97% of trainees stated that addiction represents a core curriculum for their training. Overall, general adult psychiatric trainees reported a better knowledge in addictions, compared to trainees in child and adolescent psychiatry. Conclusion: Despite a growing spread of PSUDs in European countries, addiction psychiatry is a relatively poorly trained field within psychiatry training programs. Further research should investigate reasons for poor training and timings of the educational activities to optimize experiential education training in addiction psychiatry.

Abstract
The development of coils that can survive a quench is crucial for demonstrating the viability of MgB2-based main magnet coils used in MRI systems. Here we have studied the performance and quench properties of a large (outer diameter: 901 mm; winding pack: 44 mm thick × 50.6 mm high) conduction-cooled, react-and-wind (R&W), MgB2 superconducting coil. Minimum quench energy (MQE) values were measured at several coil operating currents (I op ), and distinguished from the minimum energy needed to generate a normal zone (MGE). During these measurements, normal zone propagation velocities (NZPV) were also determined using multiple voltage taps placed around the heater zone. The conduction cooled coil obtained a critical current (I c ) of 186 A at 15 K. As the operating currents (I op ) varied from 80 A to 175 A, MQE ranged from 152 J to 10 J, and NZPV increased from 1.3 to 5.5 cm/s. Two kinds of heater were involved in this study: (1) a localized heater ("test heater") used to initiate the quench, and (2) a larger "protection heater" used to protect the coil by distributing the normal zone after a quench was detected. The protection heater was placed on the outside surface of the coil winding. The test heater was also placed on the outside surface of the coil at a small opening made in the protection heater. As part of this work, we also developed and tested an active protection scheme for the coil. Such active protection schemes are of great interest for MgB2-based MRIs because they permit exploitation of the relatively large MQE values of MgB2 to enable the use of higher J e values which in turn lead to competitive MgB2 MRI designs. Finally, the ability to use a quench detection voltage to fire a protection heater as part of an active protection scheme was also demonstrated.

Abstract
Abstract
Many countries struggle to find the best way to treat hypertension (HT) and type 2 diabetes (T2D). As a result, many patients receive suboptimal care, especially vulnerable groups in society. The SCale up Integrated Care for diaBetes and hYpertension (SCUBY) project addresses this important societal issue, by examining the scale-up of existing evidence-based interventions for the control of HT and/or T2D.
The study undertaken in countries with very different health systems, i.e. a developing health system in a low-middle income country - Cambodia; a former socialist high-income country with a centralised health system - Slovenia; and a Western European federal country with a decentralised system- Belgium, develops, implements and assesses roadmaps for the scale-up of an integrated chronic care package (ICP). The ICP consists of (a) identification of people with HT or T2D, (b) subsequent treatment in primary care services, (c) health education, (d) self-management support to patients and caregivers, and (e) collaboration between caregivers. Analysis of the organisational capacity to scale-up the ICP for T2D and HT and to assess contextual barriers and facilitators to do so, informs the development of the roadmaps. Implementation and evaluation of the 3 roadmaps, one per country, assesses the impact on health outcomes and quality of care through the scale-up of the ICP aimed to contribute to sustainable coverage of T2D and HT interventions for more people in each country.
The project is innovative because it compares different scale-up strategies for a contextualised common intervention package. It applies the conceptual insights from scale-up science to the field of non-communicable diseases and involves policy-makers, professionals and patients to ensure local relevance and impact. It will generate new knowledge on how to scale-up the ICP for T2D and HT in diverse contexts. The lessons on scale-up will benefit policy-makers in countries with similar contexts.
Key messages
Innovative strategies are needed to scale up integrated chronic care for non-communicable diseases. The SCUBY project develops, implements and assesses roadmaps for the scale-up of an integrated chronic care package for hypertension and diabetes.

Abstract
ZusammenfassungDie Nukleotid-Exzisions-Reparatur (NER) ist für die Beseitigung von ultraviolett (UV) -induzierten DNA-Schäden und damit zur Vermeidung von Hautkrebs essenziell. Menschen mit einem genetischen Defekt in der NER, Xeroderma pigmentosum (XP) -Patienten, sind äußerst sonnenempfindlich. Sie entwickeln bereits in den ersten Lebensjahren Zeichen der vorzeitigen Hautalterung mit einem deutlich erhöhten Risiko zur Entwicklung von UV-induzierten kutanen Karzinomen. DNA-Reparaturdefektsyndrome werden vorrangig in der Klinik diagnostiziert und auf molekularer Ebene bestätigt. Für die seltene, rezessiv vererbte Erkrankung XP steht zum jetzigen Zeitpunkt leider noch keine kausale Therapie zur Verfügung, weshalb eine frühe Diagnosestellung umso bedeutsamer ist. Durch frühzeitige sowie konsequente UV-protektive Maßnahmen und eine regelmäßige Überprüfung der Haut im Zuge der Hautkrebsfrüherkennung werden sowohl die Prognose als auch Krankheitsverlauf maßgeblich verbessert.

Abstract
ZusammenfassungUV-Strahlung gilt als primäre Ursache der Photokarzinogenese und trägt somit zur Entwicklung von kutanen Hautkrebsentitäten wie Plattenepithelkarzinom, Basalzellkarzinom und Melanom bei. Durch UV-Strahlung entstehen einerseits typische DNA-Photoprodukte und andererseits indirekte DNA-Schäden durch reaktive Sauerstoffspezies. UV-bedingte DNA-Schäden werden durch die Nukleotid-Exzisions-Reparatur behoben, die somit der Bildung von Mutationen und der Hautkrebsentwicklung entgegenwirkt. Durch Mutationen werden Tumorsuppressorgene inaktiviert und wachstumsfördernde Signalwege aktiviert, die die normale Zellzyklusprogression stören. Abhängig von der jeweilig zugrunde liegenden Hautkrebsentität, sind bestimmte Gene häufiger betroffen als andere. Basalzellkarzinome weisen häufig Patched- oder Smoothened-Mutationen auf, die den Sonic hedgehog-Signalweg beeinflussen. Plattenepithelkarzinome zeigen vermehrt TP53-Mutationen. Weitere Mutationen umfassen den epidermalen Wachstumsfaktorrezeptor, RAS, FYN und CDKN2A. In Melanomen konnten vor allem UV-induzierte Mutationen in TP53 und CDKN2A nachgewiesen werden. Zudem tragen UV-induzierte Entzündungsprozesse zur Photokarzinogenese bei. Neuere Studien konnten einen Einfluss von Zitrusfruchtkonsum, Alkoholkonsum, Hormonersatztherapien und oralen Kontrazeptiva auf die Photokarzinogenese feststellen. Präventive Maßnahmen gegen UV-bedingte Karzinogenese beinhalten den adäquaten Gebrauch von Sonnenschutz und regelmäßige Hautkrebsvorsorgeuntersuchungen.

Abstract
We report results from the first search for ν_{μ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

Abstract
PURPOSE To provide a rapid method to reduce the radiofrequency (RF) E-field coupling and consequent heating in long conductors in an interventional MRI (iMRI) setup. METHODS A driving function for device heating (W) was defined as the integration of the E-field along the direction of the wire and calculated through a quasistatic approximation. Based on this function, the phases of four independently controlled transmit channels were dynamically changed in a 1.5 T MRI scanner. During the different excitation configurations, the RF induced heating in a nitinol wire immersed in a saline phantom was measured by fiber-optic temperature sensing. Additionally, a minimization of W as a function of phase and amplitude values of the different channels and constrained by the homogeneity of the RF excitation field (B1) over a region of interest was proposed and its results tested on the benchtop. To analyze the validity of the proposed method, using a model of the array and phantom setup tested in the scanner, RF fields and SAR maps were calculated through finite-difference time-domain (FDTD) simulations. In addition to phantom experiments, RF induced heating of an active guidewire inserted in a swine was also evaluated. RESULTS In the phantom experiment, heating at the tip of the device was reduced by 92% when replacing the body coil by an optimized parallel transmit excitation with same nominal flip angle. In the benchtop, up to 90% heating reduction was measured when implementing the constrained minimization algorithm with the additional degree of freedom given by independent amplitude control. The computation of the optimum phase and amplitude values was executed in just 12 s using a standard CPU. The results of the FDTD simulations showed similar trend of the local SAR at the tip of the wire and measured temperature as well as to a quadratic function of W, confirming the validity of the quasistatic approach for the presented problem at 64 MHz. Imaging and heating reduction of the guidewire were successfully performed in vivo with the proposed hardware and phase control. CONCLUSIONS Phantom and in vivo data demonstrated that additional degrees of freedom in a parallel transmission system can be used to control RF induced heating in long conductors. A novel constrained optimization approach to reduce device heating was also presented that can be run in just few seconds and therefore could be added to an iMRI protocol to improve RF safety.

Abstract
The efficacy of an Actinobacillus pleuropneumoniae subunit vaccine based on ApxIA, ApxIIA, ApxIIIA and OMP-2 (Porcilis App, MSD) was investigated in two farrow-to-finish pig herds (A and B) affected by chronic pleurisy. In total, 1161 pigs were included. At three weeks of age, the pigs were randomly allocated to non-vaccinated control (NV; n=580) and vaccinated (V; n=581) groups. At 6 and 10 weeks of age, pigs were injected with Porcilis-APP (V group) or adjuvant (NV group). At slaughter (26 weeks), pleurisy and pneumonia lesions were assessed. All pigs were weighed individually at 6 and 26 weeks of age, and average daily weight gain (ADG; g/pig/day) was calculated. Mortality and days of additional treatment (DAT) were registered during the whole experiment. Data were analysed using binary logistic regression or analysis of variance for proportions or continuous variables, respectively. The prevalence of pleurisy and pneumonia was (NV-A=19.3, V-A=7.9, (P=0.000); NV-B=17.9, V-B=0.7, (P=0.000)) and (NV-A=42.4, V-A=21.2, (P=0.000); NV-B=46.7, V-B=19.0, (P=0.000)), respectively. The ADG was NV-A=632±157, V-A=647±91, (P=0.162); NV-B=660±115, V-B=670±82, (P=0.232). The mortality during the experiment was NV-A=5.7, V-A=1.8, (P=0.015); NV-B=2.3, V-B=1.0, (P=0.170) per cent. The DAT was: NV-A=15.04±1.41, V-A=14.95±0.67, (P=0.010); NV-B=21.68±2.43, V-B=16.99±0.62, (P=0.000). The present study showed a significant reduction of the prevalence of pleurisy and pneumonia, and antimicrobial use in V pigs from both herds, and in mortality in V pigs from one herd.

Abstract
A method of analysis was developed to determine free and glucuronated monobutyl phthalate (BuP) and monobenzyl phthalate (BeP) in urine for the assessment of exposure of man to butylbenzyl phthalate (BBP) in the workplace and in the environment. This method has also been applied in pharmacokinetic studies in experimental animals and the determination in urine of exposed workers. Urine samples are first subjected to enzymatic hydrolysis with ß-glucuronidase to enable the measurement of the total amount of monophthalates excreted. A fraction of the hydrolysate is used for further analysis. Monohexyl phthalate is added as an internal standard and the hydrolysed urine extracted with a n-hexane/ dichloromethane mixture after acidification and saturation with salt. The organic fractions are washed, dehydrated and evaporated. The residue is methylated by means of diazomethane dissolved in diethylether, evaporated and further purified by extraction into n-hexane from an alkaline buffer. The organic fractions are evaporated and the residue redissolved in acetonitrile for analysis by ion trap GC-MS equipped with a 50 m apolar WCOT capillary column. TIC mass chromatograms are recorded from which SIM chromatograms can be derived electronically. The m/z values used are 91, 149, and 163 which provide a sufficient sensitive response and which are specific enough to pick up the methylated monophthalates under investigation. The quantitative limit of detection (LOQ) is 60 μg/L for BuP and BeP when using the Magnum ion Trap detector and 3 μg/L when using the Polaris Q in the splitless mode. The calibration curve in urine is linear from 120 μg/L to 50,000 μg/L with a coefficient of variation of less than 10 % . In case of the Polaris Q linearity started from 10 μg/L. The recovery of the method is monitored by the response signal of the internal standard in the ion chromatogram. In the event of insufficient recovery the analysis is repeated. Variations in recovery are compensated by the internal standard of which the molecular structure is very similar to the ones of the monophthalates under investigation.

Abstract
To date, most interventions aimed at preventing obesity have underemphasized the application of systematic intervention development, implementation and evaluation. The present review provides a thorough insight in factors promoting implementation and/or effectiveness in interventions aimed at preventing overweight/obesity among adults. A total of 46 studies evaluating interventions aimed at preventing obesity were reviewed, followed by both qualitative and quantitative analyses. The Intervention Mapping protocol and the Environmental Research framework for weight Gain prevention (EnRG) were applied to analyse and classify the included studies. The interventions were categorized by setting (workplace, community, health care) and target group (ethnic minorities, pregnant women, [pre]menopausal women, smokers, people with intellectual disabilities). Generally, interventions were found to have potential in changing energy balance-related behaviours and anthropometric outcomes. Effect sizes for changes in body mass index ranged between -0.09 and 0.45. When the programme goal specifically aimed at weight management, the intervention was found to be more successful than interventions with programme goals that were aimed at preventing cardiovascular disease or improving general health status. Although a considerable part of studies included motivational interventions, only some actually assessed the effects on potential cognitive mediators. A general lack of reporting underlying theoretical models for behaviour change was observed as well as the inclusion of linkage groups and strategies to promote empowerment.

Abstract
Nine isolates from Argyrolobium uniflorum, Lotus creticus, Medicago sativa (Tunisia) and Lotus arabicus (Senegal) were analysed by multilocus sequence analysis (MLSA) of five housekeeping genes (recA, atpD, glnA, gltA and thrC), the 16S rRNA gene and the nodulation gene nodA. Analysis of the individual and concatenated gene sequences demonstrated that the nine new strains constituted three stable, well-supported (bootstrap and gene sequence similarity values) monophyletic clusters, A, B and C, all belonging to the branch of the genus Ensifer, regardless of the phylogenetic reconstruction method used (maximum likelihood, maximum-parsimony, neighbour-joining). The three groups were further characterized by API 100 auxanographic tests, host specificity and nodA gene sequence analysis. On the basis of these data, clusters A and C are suggested as representing two novel species within the genus Ensifer, for which the names Ensifer numidicus sp. nov. (type strain ORS 1407T=LMG 24690T=CIP 109850T) and Ensifer garamanticus sp. nov. (type strain ORS 1400T=LMG 24692T=CIP 109916T) are proposed. The cluster B strains were assigned to Ensifer adhaerens genomovar A.

Abstract
Abstract
Under the auspices of the Belgian Society of Medical Oncology (BSMO).Background: New drugs are generally tested in patients with metastatic disease where bulky tumor mass is present. However, antiangiogenic compounds are probably more beneficial in the prevention of regrowth from tumors with small tumor load than in bulky tumors. This study wants to test the hypothesis that antiangiogenic compounds such as sunitinib are able to delay tumor progression after tumor mass reduction by taxanes, i.e. an objective response (PR or CR).Materials and methods: This is a dual-arm open-label randomized multicenter phase II clinical trial with 2:1 randomization evaluating the efficacy of sunitinib (study arm) versus no therapy (control arm, only for descriptive purposes) in patients with metastatic breast cancer after objective response to taxane chemotherapy. Eligible patients had metastatic HER2 negative breast cancer, had received 10 to 20 weeks of first- or second line taxane containing chemotherapy resulting in an objective response (RECIST). Patients received sunitinib (arm A) 50 mg/d po 4w/6 (amended to 37.5 mg continuously in 1-2008) or no therapy (arm B). Patients were stratified for disease free interval and dominant site of disease. Patients randomized to arm B were offered the opportunity to receive open-label sunitinib treatment upon development of disease progression. Treatment was pursued until disease progression or major intolerance or patients refusal. All patients who received at least day 1 of study treatment were evaluated for efficacy, toxicity and safety. The duration of response after taxane treatment in previous studies with metastatic breast cancer is around 7 months. Based on this, the median time interval between the end of chemotherapy and tumor progression was expected to be about 5 months in our study population. The primary endpoint was to determine the proportion of patients alive and without disease progression (PFS) at 5 months after study entry in arm A. If ≤ 18/36 patients are progression-free and alive at 5 months, sunitinib will be declared insufficiently active (beta 0.05); if ≥ 22 patients are progression-free and alive at 5 months, sunitinib will be declared active (alpha 0.05) and it will be recommended to continue the trial as a phase III design.Results: 10/36 patients (28%) reached 5 months PFS in arm A and 4/19 in arm B (21%). Median PFS was 3.4 months in Arm A and 3.1 months in Arm B. Toxicity and overall survival data will be reported at the meeting.Discussion: This study does not confirm the hypothesis that sunitinib can lead to a significant proportion of patients with PFS of ≥ 5 months after objective response to taxanes. This proof-of-principle study suggests that also the role of consolidation therapy with other (already approved) antiangiogenic treatments should be evaluated carefully in prospective clinical trials (high economic cost).

Abstract
BACKGROUND AND OBJECTIVE In the last few years public interest in the care of severely ill and dying patients has been growing. The aim of palliative medicine is to improve the care of the dying. However, this is still not achieved in many general hospitals. The Liverpool Care Pathway (LCP) for the care of the dying intends to change this situation. The aim of this study was to explore the views of professionals using the LCP as a framework for ensuring good care of the dying. METHODS A qualitative study was conducted with an interdisciplinary focus group of ten professionals (nurses, physicians, spiritual adviser, social worker, physiotherapist and art therapist) to explore their views and experience after implementation of the LCP in a palliative care unit (PCU). The recorded discussion between them was transcribed verbatim and analysed using content analysis by three independent reviewers. RESULTS Seven nurses and three physicians with an average work experience of 16 years each took part in the focus group. Based on the experience of 24 patients, the LCP was evaluated as very positive by all participants. In particular, three aspects were emphasized as having high relevance for a good quality of care: improvement of self-confidence, better control of symptoms, and enhancement of the communication between professionals and with patients and their relatives. However, some weaknesses were also mentioned, e.g. inadequate effort of documenting the beginning of implementing the scheme. CONCLUSION The LCP was well received by professionals after the initial implementation of the LCP in a German PCU. The LCP was judged as an appropriate and helpful framework in the care of the dying.

Abstract
The purpose of this study was to evaluate the implementation of functional magnetic resonance imaging (fMRI) for clinical use in patients with a brain tumour in the setting of a regional hospital. Twenty-three patients underwent a fMRI examination as preoperative evaluation for a tumour adjacent to a eloquent brain area. The location and distance of the tumour relative to the fMRI activation area for this eloquent brain area was determined. Presence of postoperative neurological deficits was compared to the result of the fMRI examination. The fMRI examination was not interpretable in four of the twenty-three patients. In nine patients the eloquent brain area was located more than two centimetres from the tumour: seven showed no neurological deficit postoperatively, one patient experienced a temporary deficit, and one patient has not been operated yet. In the remaining ten patients the eloquent brain area was located less than two centimetres from the tumour: after (partial) resection of the tumour often using intra-operative cortical stimulation, six patients showed no neurological deficits, and three patients had temporary or permanent deficits. One patient was not operated. The clinical implementation of fMRI was successful in the preoperative evaluation of patients with a brain tumour and useful to plan the surgical intervention and to minimize postoperative neurological deficits.

Abstract
The objective of this study was to quantify end-organ damage caused by bacteremic sepsis. Twelve adult swine were divided into two groups. The anesthesia control group (n = 6) received general anesthesia for 4 hours. The septic shock group (n = 6) received an infusion of Aeromonas hydrophila under general anesthesia for 4 hours. Swine were sacrificed at the end of the 4-hour procedure. Tissues from lungs, kidneys, livers, and hearts were stained with hematoxylin and eosin. Images of tissues were studied with digital image analysis. In lungs, cytoplasmic area (CA), nuclear area (NA), intra-alveolar hemorrhage (IAH), total airspace (TAS), and alveolar septum thickness (ST) were measured. Nuclear and cytoplasmic intensities (NI and CI) were measured in integrated optical density units (IOD). In kidneys, livers, and hearts, CA, CI, NA, and NI were measured similarly. Sinusoidal blood in the liver and vacuolization (VAC) in the kidney were also measured. In septic lungs, CI, NA, NI, ST, IAH, TAS, and ratios of NA/CA, NI/CI, and IAH/TAS were significantly increased compared with the control (P < 0.02). In septic kidneys, CI, NA, VAC, NA/CA, and NI/CI were significantly increased (P < 0.0005). In livers, CA, CI, and NI/CI were significantly increased (P < 0.005). In hearts, the ratios of NA/CA and NI/CI were statistically significant. End organs from septic swine, with exception of the heart, showed significantly higher levels of cellular damage. Digital image analysis provides an objective, precise, and accurate method of quantifying image characteristics. Automating these tasks is a high priority in the research and clinical community in providing a reproducible method for longitudinal analysis of various biological studies.

Abstract
We present the first experimental discrimination between the 2e/3 and 4e/3 top quark electric charge scenarios, using top quark pairs (tt) produced in pp collisions at (square root) s = 1.96 TeV by the Fermilab Tevatron Collider. We use 370 pb;{-1} of data collected by the D0 experiment and select events with at least one high transverse momentum electron or muon, high transverse energy imbalance, and four or more jets. We discriminate between b- and b-quark jets by using the charge and momenta of tracks within the jet cones. The data are consistent with the expected electric charge, |q|=2e/3. We exclude, at the 92% C.L., that the sample is solely due to the production of exotic quark pairs QQ with |q|=4e/3. We place an upper limit on the fraction of QQ pairs rho<0.80 at the 90% C.L.

Abstract
We report a measurement of the Bs(0) lifetime in the semileptonic decay channel Bs(0) --> Ds- mu+ nuX (and its charge conjugate), using approximately 0.4 fb(-1) of data collected with the D0 detector during 2002-2004. Using 5176 reconstructed Ds- mu+ signal events, we have measured the Bs(0) lifetime to be tau(Bs(0))=1.398+/-0.044(stat)(-0.025)(+0.028)(syst) ps. This is the most precise measurement of the Bs(0) lifetime to date.

Abstract
A search for direct production of scalar bottom quarks (b) is performed with 310 pb(-1) of data collected by the D0 experiment in pp collisions at square root s = 1.96 TeV at the Fermilab Tevatron Collider. The topology analyzed consists of two b jets and an imbalance in transverse momentum due to undetected neutralinos (chi(1)0), with chi(1)0 assumed to be the lightest supersymmetric particle. We find the data consistent with standard model expectations, and set a 95% C.L. exclusion domain in the (m(b), m(chi(1)0)) mass plane, improving significantly upon the results from run I of the Tevatron.
