Active Care Management Supported by Home Telemonitoring in Veterans With Type 2 Diabetes

OBJECTIVE We compared the short-term efficacy of home telemonitoring coupled with active medication management by a nurse practitioner with a monthly care coordination telephone call on glycemic control in veterans with type 2 diabetes and entry A1C ≥7.5%. RESEARCH DESIGN AND METHODS Veterans who received primary care at the VA Pittsburgh Healthcare System from June 2004 to December 2005, who were taking oral hypoglycemic agents and/or insulin for ≥1 year, and who had A1C ≥7.5% at enrollment were randomly assigned to either active care management with home telemonitoring (ACM+HT group, n = 73) or a monthly care coordination telephone call (CC group, n = 77). Both groups received monthly calls for diabetes education and self-management review. ACM+HT group participants transmitted blood glucose, blood pressure, and weight to a nurse practitioner using the Viterion 100 TeleHealth Monitor; the nurse practitioner adjusted medications for glucose, blood pressure, and lipid control based on established American Diabetes Association targets. Measures were obtained at baseline, 3-month, and 6-month visits. RESULTS Baseline characteristics were similar in both groups, with mean A1C of 9.4% (CC group) and 9.6% (ACM+HT group). Compared with the CC group, the ACM+HT group demonstrated significantly larger decreases in A1C at 3 months (1.7 vs. 0.7%) and 6 months (1.7 vs. 0.8%; P < 0.001 for each), with most improvement occurring by 3 months. CONCLUSIONS Compared with the CC group, the ACM+HT group demonstrated significantly greater reductions in A1C by 3 and 6 months. However, both interventions improved glycemic control in primary care patients with previously inadequate control.
Ability of Three Endodontic Sealers to Fill the Root Canal System in Association with Gutta-Percha

Introduction: The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha. Methods: Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth were filled using the continuous wave of condensation technique. The specimens were then decalcified, dehydrated, rendered transparent, and analyzed by three independent evaluators with 8x magnification. Chi-squared test (χ2, p < 0.05) was used to compare the groups in relation to the totally filled, the partially filled and the non filled ramifications. The same test was used to compare the directions of filled ramifications and the number of ramifications among the three thirds of the roots. Results: EndoREZ filled a significantly higher number of ramifications than AH Plus and Pulp Canal Sealer (χ2, p < 0.05). All the groups showed higher number of totally filled ramifications than partially filled and unfilled ramifications. The ramifications were more frequently detected in the apical third, followed by medium and coronal thirds, respectively (χ2, p < 0.05). The ramifications were more frequently detected towards lingual direction (χ2, p < 0.05). Conclusion: EndoREZ presented higher ability to fill the root canal system in association with gutta-percha when compared to AH Plus and Pulp Canal Sealer. The ramifications were more frequently detected in the apical third, running in a lingual direction.
Identification of a change in climate state using regional flood data

Abstract. Flood frequency analysis typically assumes that annual floods arise from a single distribution and are independent. However, there is significant evidence for the existence of persistent climate modes. Timescales associated with climate variability range from inter-annual through to longer, multi-decadal time scales. In the case of the Australian climate, previous studies of the Indian and Pacific Oceans have indicated marked multi-decadal variability in both mean Sea Surface Temperatures (SST) and typical circulation patterns. In this light, data from 40 stream gauges around New South Wales are examined to determine whether flood frequency data are indeed independent and distributed identically. Given likely correlation in flood records between gauges, an assessment of the regional significance of observed changes in flood frequency is required. To achieve this, flood observations are aggregated into a regional index. A simple non-parametric test is then employed to identify the timing and magnitude of any change in mean annual flood. Finally, it is shown that the identified change in flood frequency corresponds directly to an observed shift in SST and mean circulation. These results demonstrate the role of natural variability in climate parameters and the need for an improved conceptual framework for flood frequency estimation.

Evaluation of Antiproliferative Activity of Red Sorghum Bran Anthocyanin on a Human Breast Cancer Cell Line (MCF-7)

Breast cancer is a leading cause of death in women worldwide both in the developed and developing countries. Thus effective treatment of breast cancer with potential antitumour drugs is important. In this paper, human breast cancer cell line MCF-7 has been employed to evaluate the antiproliferative activity of red sorghum bran anthocyanin. The present investigation showed that red sorghum bran anthocyanin induced growth inhibition of MCF-7 cells at significant level. The growth inhibition is dose dependent and irreversible in nature. When MCF-7 cells were treated with red sorghum bran anthocyanins due to activity of anthocyanin morphological changes were observed. The morphological changes were identified through the formation of apoptopic bodies. The fragmentation by these anthocyanins on DNA to oligonuleosomal-sized fragments, is a characteristic of apoptosis, and it was observed as concentration-dependent. Thus, this paper clearly demonstrates that human breast cancer cell MCF-7 is highly responsive by red sorghum bran anthocyanins result from the induction of apoptosis in MCF-7 cells.
Risk of HIV transmission from patients on antiretroviral therapy: A position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy

Abstract The modern medical treatment of HIV with antiretroviral therapy (ART) has drastically reduced the morbidity and mortality in patients infected with this virus. ART has also been shown to reduce the transmission risk from individual patients as well as the spread of the infection at the population level. This position statement from the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy is based on a workshop organized in the fall of 2012. It summarizes the latest research and knowledge on the risk of HIV transmission from patients on ART, with a focus on the risk of sexual transmission. The risk of transmission via shared injection equipment among intravenous drug users is also examined, as is the risk of mother-to-child transmission. Based on current knowledge, the risk of transmission through vaginal or anal intercourse involving the use of a condom has been judged to be minimal, provided that the person infected with HIV fulfils the criteria for effective ART. This probably also applies to unprotected intercourse, provided that no other sexually transmitted infections are present, although it is not currently possible to fully support this conclusion with direct scientific evidence. ART is judged to markedly reduce the risk of blood-borne transmission between people who share injection equipment. Finally, the risk of transmission from mother to child is very low, provided that ART is started well in advance of delivery.
A crosstalk avoidance method combining crosstalk avoidance code with shielding wire technique

Through-silicon vias (TSVs) play an important role as the vertical connections in three dimensional (3D) integrated circuit (IC). However, the 3D IC suffers from the increasing crosstalk noise between TSVs as the working frequency gets higher. The crosstalk in TSV arrays is more complicated than that of 2D IC because more aggressors have to be considered. This paper proposes a crosstalk avoidance method combining the crosstalk avoidance code (CAC) with the shielding wire technique by dividing the TSV array into some 3×3 sub-arrays. This method can suppress the crosstalk in TSV array below 4.5C level, which elevates the performance of 3D IC effectively.

ONLINE FEEDBACK ERROR LEARNING CONTROL FOR AN INVERTED PENDULUM

This paper presents an application of the feedback error learning technique for online control of an inverted pendulum which has uncertain friction nonlinearity. In order to build up online adaptive learning control, i) the preliminary offline training and the scaling factor for the neural network to escape from the local minimum, and ii) twostage learning scheme are introduced. After some learning cycles, the vibrations of the inverted pendulum are completely ceased that the feedback error learning scheme acts as an adaptive controller to minimize the control error. This means that the neural network acquires the inverse dynamic model of the plant through learning, and then compensates the nonlinearity of the plant. The phase relationships of the control outputs between the conventional feedback controller and the adaptive neural network controller are clarified. It is also shown that this control system works well for a step reference signal after learning.
Conventional and alternative treatment approaches for Clostridium difficile infection

Clostridium difficile-associated disease continues to be one of the leading health concerns worldwide. C. difficile is considered as a causative agent of nosocomial diarrhea that causes serious infection, which may result in death. The incidences of C. difficile infection (CDI) in developed countries have become increasingly high which may be attributed to the emergence of newer epidemic strains, extensive use of antibiotics, and limited alternative therapies. The available treatment options against CDI are expensive and promote resistance. Therefore, there is urgent need for new approaches to meet these challenges. This review discusses the current understanding of CDI, the existing clinical treatment strategies and future potential options as antidifficile agents based on the available published works.
Design and realization of an interactive medical images three dimension visualization system

In this paper, an interactive medical three-dimensional visualization system is realized based on VTK. This program is designed primarily for the CT images to realize such functions as reading and displaying of image files and interactive three-dimensional reconstruction. The threshold for three-dimensional reconstruction is interactively selected by marching squares algorithm (MS), which is more convenient and more interactive for three-dimensional reconstruction by marching cubes algorithm (MC) than the traditional method that the various reconstruction thresholds are simply entered based on experience. The functional stability and good human-computer interaction of this system greatly improve accuracy and scientificity of medical diagnosis and treatment planning. The system is designed based on modular, which is not only used as a separate visualization system for medical diagnosis, but also its functions will be further added and constantly improved aiming at the different surgical needs.
Nanostructural Characteristics of Polymer Adsorption Layers Formed under Ultrasonic Treatment on Metal Oxides Surface in Aqueous Dispersions

The course and the result of the surface modification of titanium dioxide and ferrous oxide pigments in aqueous dispersion by ethylhydroxyethylcellulose (EHEC) without and with mechanical treatment of the dispersion by ultrasonic power was studied by the electrokinetic sonic amplitude (ESA) method. The evaluation of the ESA data showed that the ultrasonic treatment causes a significant thickness increase of the EHEC layer on the pigment which is primarily attributed to the ultrasonically induced activation of the pigment surface. The thickness of the polymer adsorption layer derived from ESA measurements was confirmed by TEM investigations. The ultrasonic treatment leads to significant changes of the adsorption layers properties and is a promising method for the surface modification of pigments with regard to dispersion stability. За допомогою електрокінетичної звукової амплітуди (ЕЗА) досліджено процес модифікації поверхні пігментів діоксиду титану та оксиду заліза у водних дисперсних системах при введенні етилгідроксиетилцелюлози (ЕГЕЦ) у відсутності та в присутності механічного оброблення дисперсних систем ультразвуком. Інтерпретацією даних ЕЗА показано, що ультразвукове оброблення викликає суттєве збільшення товщини шару ЕГЕЦ на поверхні пігментів, що пояснюється ультразвуковою активацією поверхні. Дані про товщину шарів, oтримані методом ЕЗА, підтверджені дослідженнями з використанням просвічуючої електронної мікроскопії. Ультразвукове оброблення призводить до значних змін характеристик адсорбційних шарів і є перспективним методом для модифікування поверхні пігментів та підвищення стабільності дисперсних систем.
Family Disruption and Delinquency

Research teams in 3 cities interviewed 4,000 youth and their caretakers to analyze the prevalence of delinquent behaviors and drug use and the number of family transitions the youth had experienced. The researchers found that these young people had faced a substantial number of family transitions, which can result in decreased financial security and increased stress and conflict. In Rochester, NY, and Denver, CO, the number of transitions had a significant effect on delinquency and drug use, with the Pittsburgh, PA, data showing the same trend, although not at a statistically significant level.
Impact of Climate on Tourist Demand

Tourism, being volatile and situation-specific, is responsive to climate change. A cross-section analysis is conducted on destinations of OECD tourists and a factor and regression analysis on holiday activities of Dutch tourists, to find optimal temperatures at travel destination for different tourists and different tourist activities. Globally, OECD tourists prefer a temperature of 21 °C (average of the hottest month of the year) at theirchoice of holiday destination. This indicates that, under a scenario of gradual warming, tourists would spend their holidays in different places than they currently do. The factor and regression analysis suggests that preferences for climates at tourist destinations differ among age and income groups.
Controlling instabilities along a 3DVar analysis cycle by assimilating in the unstable subspace: a comparison with the EnKF

Abstract. A hybrid scheme obtained by combining 3DVar with the Assimilation in the Unstable Subspace (3DVar-AUS) is tested in a QG model, under perfect model conditions, with a fixed observational network, with and without observational noise. The AUS scheme, originally formulated to assimilate adaptive observations, is used here to assimilate the fixed observations that are found in the region of local maxima of BDAS vectors (Bred vectors subject to assimilation), while the remaining observations are assimilated by 3DVar. The performance of the hybrid scheme is compared with that of 3DVar and of an EnKF. The improvement gained by 3DVar-AUS and the EnKF with respect to 3DVar alone is similar in the present model and observational configuration, while 3DVar-AUS outperforms the EnKF during the forecast stage. The 3DVar-AUS algorithm is easy to implement and the results obtained in the idealized conditions of this study encourage further investigation toward an implementation in more realistic contexts.
An experiment specification language for goal-driven, automated performance evaluations

In performance engineering, experimentation is used to compare design alternatives, identify bottlenecks, or infer prediction functions. In many cases, performance analysts apply individual, unstructured approaches for the definition of experiments which hampers reusability, collaboration, and automation. In this paper, we introduce an experiment specification language that supports performance analysts in capturing all information required to implement a systematic performance evaluation process. The language design specifically aims at facilitating reusability, collaboration, and automation. The presented approach is applied in different scenarios at SAP development departments.
NUCLEAR CONSTRAINTS ON PROPERTIES OF NEUTRON STAR CRUSTS

The transition density ρt and pressure Pt at the inner edge separating the liquid core from the solid crust of neutron stars are systematically studied using a modified Gogny (MDI) and 51 popular Skyrme interactions within well established dynamical and thermodynamical methods. First of all, it is shown that the widely used parabolic approximation to the full equation of state (EOS) of isospin asymmetric nuclear matter may lead to huge errors in estimating the transition density and pressure, especially for stiffer symmetry energy functionals Esym(ρ), compared to calculations using the full EOS within both the dynamical and thermodynamical methods mainly because of the energy curvatures involved. Thus, fine details of the EOS of asymmetric nuclear matter are important for locating accurately the inner edge of the neutron star crust. Second, the transition density and pressure decrease roughly linearly with increasing slope parameter L of Esym(ρ) at normal nuclear matter density using the full EOS within both the dynamical and thermodynamical methods. It is also shown that the thickness, fractional mass, and moment of inertia of the neutron star crust are all very sensitive to the parameter L through the transition density ρt whether one uses the full EOS or its parabolic approximation. Moreover, it is shown that Esym(ρ) constrained in the same subsaturation density range as the neutron star crust by the isospin diffusion data in heavy-ion collisions at intermediate energies limits the transition density and pressure to 0.040 fm−3 ⩽ρt ⩽ 0.065 fm−3 and 0.01 MeV fm−3 ⩽Pt ⩽ 0.26 MeV fm−3, respectively. These constrained values for the transition density and pressure are significantly lower than their fiducial values currently used in the literature. Furthermore, the mass–radius relation and several other properties closely related to the neutron star crust are studied by using the MDI interaction. It is found that the newly constrained ρt and Pt together with the earlier estimate of ΔI/I>0.014 for the crustal fraction of the moment of inertia of the Vela pulsar impose a more stringent constraint of R ⩾ 4.7 + 4.0M/M☉ km for the radius R and mass M of neutron stars compared to previous studies in the literature.
A room-compensated virtual surround system exploiting early reflections in a reverberant room

In this paper we propose a novel methodology for rendering a surround sound in a prescribed area using a loudspeaker array, which exploits the early reflections on the walls of the room. With respect to the state of the art, the proposed technique is able to take advantage of the knowledge of the acoustic scene (i.e. room geometry and reflective properties of the walls) in order to reduce undesired wall reflections. Simulative results show that the use of room compensation enables an improved accuracy of the virtual surround.
HVDC over HVAC Transmission System: Fault Conditions Stability Study

With the increasing on the demand power, the electrical grid extended and classified to generation, transmission and distribution [1]. This increasing is required to improve the system by the new sources as the renewable energy. The renewable energy sources are considered more economic and high clean energy for the environment [2]. To link the renewable sources with the power system, its important to save the system with stable operation [3]. The increasing loads and the power system extension system can affect on the voltage stability and the unstable reactive power [4]. The Flexible AC Transmission System Devices voltage (FACT) is considered the optimum techniques to save control the system voltage and to save the feeding loads [5].
A filtration of the symmetric function space and a refinement of the Macdonald positivity conjecture

Let Λ be the space of symmetric functions and Vk be the subspace spanned by the modified Schur functions {Sλ[X/(1 − t)]}λ1≤k. We introduce a new family of symmetric polynomials, {A λ [X; t]}λ1≤k, constructed from sums of tableaux using the charge statistic. We conjecture that the polynomials A λ [X; t] form a basis for Vk and that the Macdonald polynomials indexed by partitions bounded by k expand positively in terms of our polynomials. A proof of this conjecture would not only imply the Macdonald positivity conjecture, but would substantially refine it. Our construction of the A λ [X; t] relies on the use of tableaux combinatorics and yields various properties and conjectures on the nature of these polynomials. Another important development following from our investigation is that the A λ [X; t]s seem to play the same role for Vk as the Schur functions do for Λ. In particular, this has led us to the discovery of many generalizations of properties held by the Schur functions, such as Pieri and LittlewoodRichardson type coefficients.

Information and the Intermediary: Are Market Intermediaries Informed Traders in Electronic Markets?

Abstract A significant but unresolved question in the current debate about the role of intermediaries in financial markets is whether intermediaries behave as passive traders or whether they actively seek and trade on information. We address this issue by explicitly comparing the informational advantages of intermediaries with those of other investors in the market. We find that intermediaries account for greater price discovery than other institutional and individual investors in spite of initiating fewer trades and volume. Furthermore, intermediary information does not arise from inappropriate handling of customer orders by intermediaries. We propose that our findings are consistent with noisy rational expectations models, where agents extract valuable information from past prices. Intermediaries bear little or no opportunity cost of monitoring market conditions, which gives them an advantage in making profitable price-contingent trades. Lower trading costs may also enable intermediaries to trade more effectively and frequently on their information.
