SFCE (Société Française de Lutte contre les Cancers et Leucémies de l'Enfant et de l'Adolescent) Recommendations for the Management of Tumor Lysis Syndrome (TLS) With Rasburicase: An Observational Survey

Rasburicase (Fasturtec), a recombinant urate oxidase, is highly effective in preventing and treating hyperuricemia in children with hematologic malignancies. We conducted a prospective, multicenter observational study in 174 patients at 8 pediatric hemato-oncology centers to establish whether the SFCE (Société Française de Lutte contre les Cancers et Leucémies de l'Enfant et de l'Adolescent) recommendations for the use of rasburicase in the management of pediatric patients at risk of tumor lysis syndrome (TLS) are valid in routine clinical practice. Patients were classified as being at high or low risk of TLS according to the Children's Oncology Group criteria and were treated in accordance with the SFCE recommendations. The primary end point was the number of patients requiring a higher dose of rasburicase or a longer duration of treatment than advised in the SFCE recommendations. Of the 135 patients at high risk of TLS, 27 patients received a higher dose and 35 patients received a longer duration of treatment. Some patients received treatment with rasburicase for less than the recommended duration (median 4 d for high-risk patients). One patient required hemodialysis. Only minor adjustments to the SFCE recommendations were required to ensure the optimal use of rasburicase in pediatric patients at risk of TLS.
Effect of unbalanced voltage on operation of induction motors and its detection

Deficiencies like unbalanced voltages in the voltage source could result in problems like excessive losses, over-voltages, mechanical oscillations, and interference with control electronics. Detecting these abnormal conditions in the machine is of great importance in the interaction of the electrical machine and the power grid. In this paper the effect of the unbalanced voltages on the motor performance, have been investigated. Then, monitoring these unhealthy condition using electrical machine parameters is carried out. In this case, motor itself can act as the sensor that detects abnormal conditions. Also this paper investigates the negative effects of unbalanced sinusoidal voltage which always present in the power supply voltage on the performance of induction motor in terms of line currents, power factor and efficiency. According to the test results and analysis, the unbalanced sinusoidal voltage has very negative effects on the motor's performance.
Acquisition and Duration of Vancomycin-Resistant Enterococcal Carriage in Relation to Strain Type

ABSTRACT In May 2000, the first outbreak of vancomycin-resistant Enterococcus faecium (VREF) was detected in the University Medical Center Utrecht in the nephrology ward. The question arose why some VREF strains spread among hospitalized patients, whereas other strains do not. Thirty patients who were found to be colonized with VREF between May and November 2000 were included in the study. Molecular typing confirmed that 19 of them carried an identical epidemic strain which harbored the esp gene while 11 were colonized by nonepidemic strains that were all esp negative. Acquisition of the outbreak strain was significantly associated with diabetes mellitus, renal transplantation, and extensive use of antibiotics, especially cephalosporins, in the 2-month period before the first isolation of VREF. To establish the duration of colonization, prospective surveillance of VREF carriage for a 6-month period starting from the first isolation of VREF was realized for 20 patients. After 6 months, VREF was still recovered from 60% of carriers of the outbreak strain versus 20% of carriers of nonepidemic strains (P < 0.01). However, antibiotic use during the follow-up period was significantly higher by carriers of the outbreak strain than by carriers of nonepidemic strains. The fact that the outbreak strain was recovered for a longer period of time than nonepidemic strains may facilitate dissemination of the strain. The results support a careful restrictive antibiotic policy for wards at risk for spread of VREF and implementation of isolation precautions for patients who are colonized with esp-positive outbreak strains.
Mating opportunities and mating costs are reduced in androchrome female damselflies,
 Ischnura elegans
 (Odonata)

Female colour polymorphism is a perplexing characteristic of many damselfly species. In Ischnura elegans three female phenotypes occur, one of which has the same blue coloration as the male (androchromes) whilst the others are inconspicuous brown gynochromes (infuscans and infuscans-obsoleta morphs). By marking a natural population near Rome, Italy, we found that all female phenotypes have similar survivorship, but they differ in mating frequency. Androchromes represented 55% of females but were involved in 43% of matings, whereas infuscans females represented 27% of females and 40% of matings and the infuscans-obsoleta phenotype 18% of females and 17% of matings. Old androchromes stored significantly less sperm in their spermatheca than old gynochromes, suggesting that they had mated less often. The majority of mature androchromes were observed alone (54%) when the majority of gynochromes (82-84%) were mating. When live tethered conspecifics were presented to males, blue models (male and androchrome female) were less attractive than brown models (gynochrome females). In contrast, all female colour morphs and males were equally (highly) attractive to males when the models were dead. Androchromes were significantly larger than gynochromes. Our results indicate that androchrome females mate less often than gynochromes, which could be a means of avoiding unnecessary and costly matings, but some androchrome females failed to reproduce (mate or oviposit) probably because they were unable to mate at all. The different explanations for the maintenance of this polymorphism in I. elegans are discussed. Copyright 1998 The Association for the Study of Animal Behaviour.
The Disparity in Long-Term Survival after a First Stroke in Patients with and without Diabetes Persists: The Northern Sweden MONICA Study

Background: Diabetes is an established risk factor for stroke. Compared to nondiabetic patients, diabetic patients also have an increased risk of new vascular events and death after stroke. We analyzed how differences in long-term survival between diabetic and nondiabetic stroke patients have changed over time, and if differences varied with respect to sex and age. Methods: This population-based study included 12,375 first-ever stroke patients, 25–74 years old, who were registered in the Northern Sweden MONICA Stroke Registry 1985–2005. Uniform diagnostic criteria for stroke case ascertainment were used throughout the study period. The diagnosis of diabetes was based on medical records or diabetes diagnosed during the acute stroke event. Patients were separated into four cohorts according to year of stroke and followed for survival until August 30, 2008. Results: The diabetes prevalence at stroke onset was 21%, similar in men and women, and remained stable throughout the study period. The diabetic patients were an average of 2 years older, more often nonsmokers and more likely to have antihypertensive treatment, antithrombotics, atrial fibrillation, and a history of myocardial infarction or transient ischemic attack than the nondiabetic patients. The total follow-up time was 86,086 patient-years during which a total of 1,930 (75.7%) of the diabetic patients and 5,744 (58.5%) of the nondiabetic patients died (p < 0.001). Median survival was 60 months (95% CI: 57–64) in diabetic patients and 117 months (113–120) in the nondiabetic patients. Survival improved significantly in both groups (p < 0.001). A Cox regression, adjusting for possible confounders (age, sex, antihypertensive medication, antithrombotics or other thrombolytic agents, history of myocardial infarction, type of stroke, diabetes, cohort and the diabetes-by-sex, diabetes-by-age and diabetes-by-cohort interactions), showed a hazard ratio of 1.67 (1.58–1.76) comparing survival in diabetic versus nondiabetic patients. The reduced survival in diabetic stroke patients was more pronounced in women (p = 0.02) and younger patients (p < 0.001). There was a tendency that the difference in survival decreased between the earlier cohorts and the 2000–2005 cohort, but the test for interaction did not reach statistical significance (p = 0.08). Conclusion: Long-term survival after a first stroke has improved in both diabetic and nondiabetic patients. Survival is markedly lower in diabetics, especially in women and younger patients, and the disparity persisted over 24 years. Decreasing the disparity in stroke survival is a challenge for stroke and diabetes care. New treatment methods in combination with intense secondary prevention in diabetic patients, especially in younger women, are needed.
Fructose: It’s “Alcohol Without the Buzz”

What do the Atkins Diet and the traditional Japanese diet have in common? The Atkins Diet is low in carbohydrate and usually high in fat; the Japanese diet is high in carbohydrate and usually low in fat. Yet both work to promote weight loss. One commonality of both diets is that they both eliminate the monosaccharide fructose. Sucrose (table sugar) and its synthetic sister high fructose corn syrup consist of 2 molecules, glucose and fructose. Glucose is the molecule that when polymerized forms starch, which has a high glycemic index, generates an insulin response, and is not particularly sweet. Fructose is found in fruit, does not generate an insulin response, and is very sweet. Fructose consumption has increased worldwide, paralleling the obesity and chronic metabolic disease pandemic. Sugar (i.e., fructose-containing mixtures) has been vilified by nutritionists for ages as a source of “empty calories,” no different from any other empty calorie. However, fructose is unlike glucose. In the hypercaloric glycogen-replete state, intermediary metabolites from fructose metabolism overwhelm hepatic mitochondrial capacity, which promotes de novo lipogenesis and leads to hepatic insulin resistance, which drives chronic metabolic disease. Fructose also promotes reactive oxygen species formation, which leads to cellular dysfunction and aging, and promotes changes in the brain’s reward system, which drives excessive consumption. Thus, fructose can exert detrimental health effects beyond its calories and in ways that mimic those of ethanol, its metabolic cousin. Indeed, the only distinction is that because fructose is not metabolized in the central nervous system, it does not exert the acute neuronal depression experienced by those imbibing ethanol. These metabolic and hedonic analogies argue that fructose should be thought of as “alcohol without the buzz. ”
Cell wall composition plays a key role on sensitivity of filamentous fungi to chitosan

Chitosan antifungal activity has been reported for both filamentous fungi and yeast. Previous studies have shown fungal plasma membrane as main chitosan target. However, the role of the fungal cell wall (CW) in their response to chitosan is unknown. We show that cell wall regeneration in Neurospora crassa (chitosan sensitive) protoplasts protects them from chitosan damage. Caspofungin, a β‐1,3‐glucan synthase inhibitor, showed a synergistic antifungal effect with chitosan for N. crassa but not for Pochonia chlamydosporia, a biocontrol fungus resistant to chitosan. Chitosan significantly repressed N. crassa genes involved in β‐1,3‐glucan synthesis (fks) and elongation (gel‐1) but the chitin synthase gene (chs‐1) did not present changes in its expression. N. crassa cell wall deletion strains related to β‐1,3‐glucan elongation (Δgel‐1 and Δgel‐2) were more sensitive to chitosan than wild type (wt). On the contrary, chitin synthase deletion strain (Δchs‐1) showed the same sensitivity to chitosan than wt. The mycelium of P. chlamydosporia showed a higher (ca. twofold) β‐1,3‐glucan/chitin ratio than that of N. crassa. Taken together, our results indicate that cell wall composition plays an important role on sensitivity of filamentous fungi to chitosan.
On the increase rate of random fields from space Subφ(Ω) on unbounded domains

This paper mainly focuses on the estimates for distribution of supremum for the normalized φ-sub-Gaussian random fields defined on the unbounded domain. In particular, we obtain the estimates for distribution of supremum for the normalized solution of the hyperbolic equation of mathematical physics, which will be useful to construct modeless. By using this result, we can approximate the solutions of such equation with given accuracy and reliability in the uniform metric.
If You Build It, Will They Come? Foreign Aid's Effects on Foreign Direct Investment

While much scholarly debate has focused on the general economic growth effects of foreign aid, little work has addressed the potential and more direct link between foreign aid and foreign direct investment (FDI), which many believe fosters growth. This is no minor deficiency; FDI has increased exponentially over the last thirty years, much of it flowing into developing countries. We test the theory that infrastructure foreign aid, such as projects for communications, transportation, and energy production, will lead to increases in FDI by providing more favorable investment conditions for multinational corporations. We test this on an unbalanced panel of 52 countries from the 1982-1995 and find that, while aid generally has no statistically significant effect on inflows of FDI, aid for infrastructure has a significant and substantive effect.
Entity Embedding-Based Anomaly Detection for Heterogeneous Categorical Events

Anomaly detection plays an important role in modern data-driven security applications, such as detecting suspicious access to a socket from a process. In many cases, such events can be described as a collection of categorical values that are considered as entities of different types, which we call heterogeneous categorical events. Due to the lack of intrinsic distance measures among entities, and the exponentially large event space, most existing work relies heavily on heuristics to calculate abnormal scores for events. Different from previous work, we propose a principled and unified probabilistic model APE (Anomaly detection via Probabilistic pairwise interaction and Entity embedding) that directly models the likelihood of events. In this model, we embed entities into a common latent space using their observed co-occurrence in different events. More specifically, we first model the compatibility of each pair of entities according to their embeddings. Then we utilize the weighted pairwise interactions of different entity types to define the event probability. Using Noise-Contrastive Estimation with "context-dependent" noise distribution, our model can be learned efficiently regardless of the large event space. Experimental results on real enterprise surveillance data show that our methods can accurately detect abnormal events compared to other state-of-the-art abnormal detection techniques.
Invasive fungal infections in liver transplant recipients receiving tacrolimus as the primary immunosuppressive agent.

Invasive fungal infections and their risk factors were prospectively assessed in 130 consecutive liver transplant recipients receiving tacrolimus as the primary immunosuppressive agent. Eleven percent (14) of the 130 patients had 17 episodes of invasive fungal infections. These included candidiasis (5%; 6 patients), cryptococcosis (5%; 6), aspergillosis (3%; 4), and chromomycosis (1%; 1). An elevated pretransplantation creatinine level, requirement of dialysis (pretransplantation or posttransplantation), duration of intensive care unit stay after transplantation surgery, and antibiotic use (other than for prophylaxis) within 4 weeks of transplantation were significant risk factors for fungal infections occurring within 100 days of transplantation. For fungal infections occurring after 100 days, persistence of renal dysfunction (serum creatinine level of >2.5 mg/dL at 3 months), dialysis, and histopathologically documented recurrence of hepatitis C virus hepatitis were significant risk factors. Mortality was significantly higher among patients with fungal infections than among all other patients (57% vs. 15%; P = .0009). Our study identified specific risk factors for invasive fungal infections in liver transplant recipients receiving tacrolimus; strategies to prevent fungal infections or to initiate early antifungal therapy might be most effectively targeted at these patients.
Adaptive Virtual Machine Migration Mechanism for Energy Efficiency

Cloud systems have become a popular platform for businessapplications due to the exibility in usage and payment theyoer. One of the caveats of Cloud systems is their high en-ergy consumption. Minimizing energy consumption whilemaintaining a high service level has become a relevant opti-mization task for Cloud providers. Opportunities for energysavings arise when server hosts are overloaded, which alsoentails unnecessary delays.To address the problem, researchers have devised strate-gies how to choose the server host to deploy an application toand how to choose a running application for migration whena host has been identied as overloaded. In this work, weintroduce a Bayesian Belief Network which learns over timewhich of the virtual machines are best removed from a hostthat has been identied as overloaded. The probabilisticchoice is made among virtual machines that are grouped bytheir degree of CPU usage. Given the feedback in the formof the computing resources saved, the system learns whichvirtual machine proles should be shifted for best perfor-mance. This strategy compares favourably to two existingmethods for load balancing.
Vascular endothelial growth factor upregulates expression of ADAMTS1 in endothelial cells through protein kinase C signaling.

PURPOSE ADAMTS1 (a disintegrin and metalloproteinase with thrombospondin motifs) has been demonstrated to inhibit angiogenesis in vivo and to suppress endothelial cell proliferation in vitro. The purpose of this study was to investigate the expression of ADAMTS1 in endothelial cells and in a mouse model of ischemia-induced retinal neovascularization and to study the regulation of ADAMTS1 expression in endothelial cells by vascular endothelial growth factor (VEGF). In addition, the potential function of endothelial cell-derived ADAMTS1 on cell proliferation was investigated. METHODS Expression of ADAMTS1 in human retinal endothelial cells (HRECs), human umbilical vein endothelial cells (HUVECs), and the mouse model of ischemia-induced retinal neovascularization was assayed by real-time PCR and Western blot analysis. The effect of ADAMTS1 on endothelial cell proliferation was evaluated using siRNA knockdown and [3H] thymidine incorporation. RESULTS ADAMTS1 mRNA and protein levels were increased in a mouse model of ischemia-induced retinal neovascularization, and VEGF induced time- and dose-dependent increases in ADAMTS1 mRNA and protein expression in endothelial cells. This upregulation was inhibited by the VEGF receptor (VEGFR)2 inhibitor SU1498, anti-VEGFR2 neutralizing antibody, and the phospholipase C (PLC)-gamma inhibitor U73122. VEGF upregulation of ADAMTS1 expression was completely abolished by the inhibition of protein kinase C by calphostin C and largely blocked by the specific inhibition of PKCbeta. Knockdown of endogenous ADAMTS1 resulted in increased proliferation of endothelial cells. CONCLUSIONS These results indicate that VEGF significantly induces ADAMTS1 expression in endothelial cells in a PKC-dependent fashion. ADAMTS1 expression is also increased, along with VEGF expression, in vivo in ischemia-induced retinal neovascularization. In addition, ADAMTS1 appears to be an endogenous regulator of endothelial cell proliferation. Therefore, VEGF upregulation of ADAMTS1, a potent angiogenesis inhibitor, may represent a mechanism for feedback inhibition of angiogenesis and retinal neovascularization.
Probing the Behaviors of Gold Nanorods in Metastatic Breast Cancer Cells Based on UV-vis-NIR Absorption Spectroscopy

In this work, behaviors of positively-charged AuNRs in a highly metastatic tumor cell line MDA-MB-231 are examined based on UV-vis-NIR absorption spectroscopy in combination with inductively coupled plasma mass spectrometry (ICP-MS), transmission electron microscopy (TEM) and dark-field microscopic observation. It is found that characteristic surface plasmon resonance (SPR) peaks of AuNRs can be detected using spectroscopic method within living cells that have taken up AuNRs. The peak area of transverse SPR band is shown to be proportionally related to the amount of AuNRs in the cells determined with ICP-MS, which suggests a facile and real time quantification method for AuNRs in living cells. The shape of longitudinal SPR band in UV-vis-NIR spectrum reflects the aggregation state of AuNRs in the cells during the incubation period, which is proved by TEM and microscopic observations. Experimental results reveal that AuNRs are internalized by the cells rapidly; the accumulation, distribution and aggregation of AuNRs in the cells compartments are time and dose dependent. The established spectroscopic analysis method can not only monitor the behaviors of AuNRs in living cells but may also be helpful in choosing the optimum laser stimulation wavelength for anti-tumor thermotherapy.
Patterns of Information-Seeking for Cancer on the Internet: An Analysis of Real World Data

Although traditionally the primary information sources for cancer patients have been the treating medical team, patients and their relatives increasingly turn to the Internet, though this source may be misleading and confusing. We assess Internet searching patterns to understand the information needs of cancer patients and their acquaintances, as well as to discern their underlying psychological states. We screened 232,681 anonymous users who initiated cancer-specific queries on the Yahoo Web search engine over three months, and selected for study users with high levels of interest in this topic. Searches were partitioned by expected survival for the disease being searched. We compared the search patterns of anonymous users and their contacts. Users seeking information on aggressive malignancies exhibited shorter search periods, focusing on disease- and treatment-related information. Users seeking knowledge regarding more indolent tumors searched for longer periods, alternated between different subjects, and demonstrated a high interest in topics such as support groups. Acquaintances searched for longer periods than the proband user when seeking information on aggressive (compared to indolent) cancers. Information needs can be modeled as transitioning between five discrete states, each with a unique signature representing the type of information of interest to the user. Thus, early phases of information-seeking for cancer follow a specific dynamic pattern. Areas of interest are disease dependent and vary between probands and their contacts. These patterns can be used by physicians and medical Web site authors to tailor information to the needs of patients and family members.
