    Owing to encouraging results achieved in the clinical practice, CT colonography (CTC) is being increasingly employed for the examination of the whole colon and rectum and is quickly becoming a widely accepted diagnostic technique that is replacing double contrast barium enema and appears a promising tool for colorectal cancer screening as well. The increasing number of symptomatic and asymptomatic patients undergoing CTC for both evaluation of symptoms and colorectal cancer screening, along with the growing availability of CTC facilities in most healthcare departments and imaging centres, requires that a sufficient number of radiologists be adequately trained in performing and interpreting CTC studies. Indeed, optimal performance of CTC depends on a number of factors, including the quality of colonic preparation (e.g. laxative bowel cleansing and optimised colonic distension), the CTC image acquisition protocol used, and reading approach and specific skills of radiologists for correct detection and interpretation of colonic findings. Consequently, dedicated training and expertise is key to obtain high sensitivity in lesion detection and reduce the number of false positives, thus ensuring an optimal clinical management of patients. To this purpose, dedicated training programmes are essential to teach and standardise not only the approach to CTC reading, but also reporting of colonic findings

    To determine the sensitivity of computed tomographic colonography (CTC) in the detection of colorectal cancer in our population and evaluate the reasons why these lesions may be missed on CTC. All patients who underwent CTC in the 65-month period from 1 January 2004 to 1 July 2009 were included in the analysis. Demographic data and CTC findings were recorded, according to the CT Colonography Reporting and Data System. Data were cross-matched with the National Cancer Registry results for colorectal cancer cases between 1 January 2004 and 1 October 2009, 3 months longer to include any delayed diagnoses. There were 2026 consecutive CTC patients, comprising 52.6% female, average age of 60 years; range 19-87. Approximately 84% were symptomatic. There were 45 confirmed colorectal cancers among this patient group in the National Cancer Registry during the relevant time period compared with 43 suspected cancers on CTC, giving a miss rate of 2 of 45, or 4.4%. The sensitivity of 95% for CTC in the detection of colorectal cancer compares favourably with the published national and international data. © 2013 The Authors.

    In this article, we review the current status of CT colonography (CTC) in Europe and future perspectives of CTC including fecal tagging and CAD. There are several large multi-centre studies that have been initiated. Fecal tagging has gradually become a prerequisite to perform state-of-the-art CTC. However, CAD for fecal-tagging CTC remains a subject for future research. (orig.)

    Full Text Available Preexisting comorbidity adversely impacts breast cancer treatment and outcomes. We examined the incremental impact of comorbidity undetected until cancer. We followed breast cancer patients in SEER-Medicare from 12 months before to 84 months after diagnosis. Two comorbidity indices were constructed: the National Cancer Institute index, using 12 months of claims before cancer, and a second index for previously undetected conditions, using three months after cancer. Conditions present in the first were excluded from the second. Overall, 6,184 (10.1% had ≥1 undetected comorbidity. Chronic obstructive pulmonary disease (38% was the most common undetected condition. In multivariable analyses that adjusted for comorbidity detected before cancer, older age, later stage, higher grade, and poor performance status all were associated with higher odds of ≥1 undetected comorbidity. In stage I–III cancer, undetected comorbidity was associated with lower adjusted odds of receiving adjuvant chemotherapy (Odds Ratio (OR = 0.81, 95% Confidence Interval (CI 0.73–0.90, P<0.0001; OR=0.38, 95% CI 0.30–0.49, P<0.0001; index score 1 or ≥2, respectively, and with increased mortality (Hazard Ratio (HR = 1.45, 95% CI 1.38–1.53, P<0.0001; HR=2.38, 95% CI 2.18–2.60, P<0.0001; index score 1 or ≥2. Undetected comorbidity is associated with less aggressive treatment and higher mortality in breast cancer.

    Malignant mesothelioma (MM) is a highly aggressive malignant tumor, predominantly associated with job-related exposure to asbestos. Development of effective and non-invasive modalities for diagnosis is an important issue in occupational medicine. Circulating tumor cells (CTCs), which are tumor cells that are shed from primary tumors and circulate in the peripheral blood, may be detected at an earlier stage than malignant tumors, and detection of CTCs may provide a novel insight into the diagnosis of MM. In a previous study evaluating clinical utility of CTCs, detected with a widely used system 'CellSearch', the authors indicated a significant however insufficient capability in the diagnosis of MM, suggesting need for a more sensitive system. Accordingly, the authors developed a novel microfluidic system to capture CTCs (CTC-chip), and demonstrated that the CTC-chip effectively captured MM cells (ACC-MESO-4) spiked in the blood by conjugating an anti-podoplanin antibody. The results of the present study demonstrated that the CTC-chip coated with the anti-podoplanin antibody captured another MM cell (ACC-MESO-1). However, the capture efficiencies were lower than those for ACC-MESO-4. In addition, an anti-mesothelin antibody was used to capture CTCs, however the CTC-chip coated with the anti-mesothelin antibody failed to effectively capture MM cells, possibly due to low mesothelin expression. Overall, the CTC-chip may capture specific types of CTCs by conjugating any antibody against an antigen expressed on CTCs, and may be a useful system for the diagnosis of malignant tumors, including MM.

    Full Text Available Circulating Tumor Cells (CTC are rare cells originated from tumors that travel into the blood stream, extravasate to different organs of which only a small fraction will develop into metastasis. The presence of CTC enumerated with the CellSearch system is associated with a relative short survival and their continued presence after the first cycles of therapy indicates a futile therapy in patients with metastatic carcinomas. Detailed characterization of CTC holds the promise to enable the choice of the optimal therapy for the individual patients during the course of the disease. The phenotype, physical and biological properties are however not well understood making it difficult to assess the merit of recent technological advancements to improve upon the capture of CTC or to evaluate their metastatic potential. Here we will discuss the recent advances in the classification of CTC captured by the CellSearch system, the implications of their features and numbers. Latest capture platforms are reviewed and placed in the light of technology improvements needed to detect CTC. Physical properties, phenotype, viability and proliferative potential and means to assess their proliferation and metastatic capacity will be summarized and placed in the context of the latest CTC capture platforms.

    Current knowledge about risk factors for child sexual abuse and child pornography offenses is based on samples of convicted offenders, i.e., detected offenders. Only few studies focus on offenders not detected by the criminal justice system. In this study, a sample of 345 self-referred pedophiles and hebephiles was recruited from the community. All participants met DSM-IV-TR criteria for pedophilia or hebephilia (paraphilia not otherwise specified), were assured of confidentiality, and self-reported lifetime sexual offending against prepubescent and/or pubescent children. Two sets of group comparisons were conducted on self-report data of risk factors for sexual reoffending. Measures of risk factors address the following dimensions identified in samples of convicted offenders: sexual preferences (i.e. co-occurring paraphilias), sexual self-regulation problems, offense-supportive cognitions, diverse socio-affective deficits, and indicators of social functioning (e.g., education, employment). Men who admitted current or previous investigation or conviction by legal authorities (detected offenders) were compared with those who denied any detection for their sexual offenses against children (undetected offenders). Group comparisons (detected vs. undetected) were further conducted for each offense type separately (child pornography only offenders, child sexual abuse only offenders, mixed offenders). Although there were more similarities between undetected and detected offenders, selected measures of sexual-self regulation problems, socio-affective deficits, and social functioning data demonstrated group differences.

  16. Circulating tumor cells: clinically relevant molecular access based on a novel CTC flow cell.

    Directory of Open Access Journals (Sweden)

    Jessamine P Winer-Jones

    Full Text Available BACKGROUND: Contemporary cancer diagnostics are becoming increasing reliant upon sophisticated new molecular methods for analyzing genetic information. Limiting the scope of these new technologies is the lack of adequate solid tumor tissue samples. Patients may present with tumors that are not accessible to biopsy or adequate for longitudinal monitoring. One attractive alternate source is cancer cells in the peripheral blood. These rare circulating tumor cells (CTC require enrichment and isolation before molecular analysis can be performed. Current CTC platforms lack either the throughput or reliability to use in a clinical setting or they provide CTC samples at purities that restrict molecular access by limiting the molecular tools available. METHODOLOGY/PRINCIPAL FINDINGS: Recent advances in magetophoresis and microfluidics have been employed to produce an automated platform called LiquidBiopsy®. This platform uses high throughput sheath flow microfluidics for the positive selection of CTC populations. Furthermore the platform quantitatively isolates cells useful for molecular methods such as detection of mutations. CTC recovery was characterized and validated with an accuracy (<20% error and a precision (CV<25% down to at least 9 CTC/ml. Using anti-EpCAM antibodies as the capture agent, the platform recovers 78% of MCF7 cells within the linear range. Non specific recovery of background cells is independent of target cell density and averages 55 cells/mL. 10% purity can be achieved with as low as 6 CTCs/mL and better than 1% purity can be achieved with 1 CTC/mL. CONCLUSIONS/SIGNIFICANCE: The LiquidBiopsy platform is an automated validated platform that provides high throughput molecular access to the CTC population. It can be validated and integrated into the lab flow enabling CTC enumeration as well as recovery of consistently high purity samples for molecular analysis such as quantitative PCR and Next Generation Sequencing. This tool opens

    Transformation acoustics is a method to design novel acoustic devices, while the complexity of the material parameters hinders its progress. In this paper, we analytically present a three-dimensional perfect undetectable acoustic device from Fabry-Pérot resonances and confirm its functionality from Mie theory. Such a mechanism goes beyond the traditional transformation acoustics. In addition, such a reduced version can be realized by holey-structured metamaterials. Our theory paves a way to the implementation of three-dimensional transformation acoustic devices.

    Full Text Available Routine investigation of serum calcium is not recommended in ASA one and two patients unless abnormalities of calcium metabolism are clinically suspected. The clinical features of hypocalcaemia can often be subtle and may manifest in the presence of associated factors. Hypoparathyroidism, an important cause of hypocalcaemia, often presents as soft tissue calcification (ostosis. Ligamentum flavum ostosis can present with compressive myelopathy requiring laminectomy. We report a case of ligamentum flavum ostosis and subclinical hypocalcaemia due to hypoparathyroidism, who went undetected pre-operatively resulting in significant post-operative morbidity.

    2003-01-01

    A method was established for staining and counting of actively respiring bacteria in natural stone by using the tetrazolium salt 5-cyano-2,3-ditolyltetrazolium chloride (CTC) in combination with confocal laser scanning microscopy (CLSM). Applying 5 mM CTC for 2 h to pure cultures of representative stone-inhabiting microorganisms showed that chemoorganotrophic bacteria and fungi-in contrast to lithoautotrophic nitrifying bacteria-were able to reduce CTC to CTF, the red fluorescing formazan crystals of CTC. Optimal staining conditions for microorganisms in stone material were found to be 15 mM CTC applied for 24 h. The cells could be visualized on transparent and nontransparent mineral materials by means of CLSM. A semi-automated method was used to count the cells within the pore system of the stone. The percentage of CTC-stained bacteria was dependent on temperature and humidity of the material. At 28 degrees C and high humidity (maximum water holding capacity) in the laboratory, about 58% of the total bacterial microflora was active. On natural stone exposed for 9 years at an urban exposure site in Germany, 52-56% of the bacterial microflora was active at the east, west, and north side of the specimen, while only 18% cells were active at the south side. This is consistent with microclimatic differences on the south side which was more exposed to sunshine thus causing UV and water stress as well as higher temperatures on a microscale level. In combination with CLSM, staining by CTC can be used as a fast method for monitoring the metabolic activity of chemoorganotrophic bacteria in monuments, buildings of historic interest or any art objects of natural stone. Due to the small size of samples required, the damage to these objects and buildings can be minimized.

    Full Text Available Objective. We present the case of a 73-year-old female, with no family or personal history of a bleeding disorder, who had a classic presentation for acquired hemophilia A. Factor VIII activity was low but detectable and a factor VIII inhibitor was undetectable. Methods. The patient’s plasma was comprehensively studied to determine the cause of the acquired coagulopathy. Using the Nijmegen modification of the Bethesda assay, no factor VIII autoantibody was measureable despite varying the incubation time from 1 to 3 hours. Results. The aPTT was prolonged at 46.8 seconds, which did not correct in the 4 : 1 mix but did with 1 : 1 mix. Using a one stage factor VIII activity assay, the FVIII activity was 16% and chromogenic FVIII activity was also 16%. The patient was treated with recombinant FVII and transfusion, significantly reducing bleeding. Long-term therapy was initiated with cyclophosphamide and prednisone with normalization of FVIII activity. Conclusions. Physicians can be presented with the challenging clinical picture of an acquired factor VIII inhibitor without a detectable inhibitor by the Bethesda assay. Standard therapy for an acquired hemophilia A should be considered.

    2017-07-26

    Quantum spectroscopy and imaging with undetected idler photons have been demonstrated by measuring one-photon interference between the corresponding entangled signal fields from two spontaneous parametric down conversion (SPDC) crystals. In this Report, we present a new quantum optical measurement scheme utilizing three SPDC crystals in a cascading arrangement; here, neither the detection of the idler photons which interact with materials of interest nor their conjugate signal photons which do not interact with the sample is required. The coherence of signal beams in a single photon W-type path-entangled state is induced and modulated by indistinguishabilities of the idler beams and crucially the quantum vacuum fields. As a result, the optical properties of materials or objects interacting with the idler beam from the first SPDC crystal can be measured by detecting second-order interference between the signal beams generated by the other two SPDC crystals further down the set-up. This gedankenexperiment illustrates the fundamental importance of vacuum fields in generating an optical tripartite entangled state and thus its crucial role in quantum optical measurements.

  4. Teenage motherhood: its relationship to undetected learning problems.

    Rauch-Elnekave, H

    1994-01-01

    This study describes characteristics of a group of 64 adolescent mothers and their infants who participated in a program for teenage mothers run by a local health department. A majority of the girls for whom California Achievement Test (CAT) scores were available scored one or more years below grade level in reading and in language skills. Relative delays in infant development (language and social domains) were also documented. High levels of self-esteem as well as general social acceptance (by adults and peers) of early out-of-wedlock parenting suggest that early motherhood may represent an alternative avenue to experiencing success for girls who are having academic difficulties. These findings, which suggest the likelihood of a high incidence of undetected learning problems in this population, indicate that these difficulties may have a significant relationship to the high rate of school dropout associated with adolescent motherhood. The findings bring into question the notion of "unintended pregnancies" and the wisdom of current federal policies for preventing adolescent parenthood that rely on the promotion of abstinence.

    Comorbid post-traumatic stress disorder (PTSD) is associated with poorer outcomes of other disorders, but is treatable. Aims To estimate the frequency of clinically undetected PTSD in secondary care. A systematic review of studies that screened for PTSD and reported on PTSD documentation in clinical records. Frequency of undetected PTSD was estimated, and reasons for heterogeneity explored. The median proportion of participants with undetected PTSD (29 studies) was 28.6% (interquartile range 18.2-38.6%). There was substantial heterogeneity, with studies conducted in the USA and those with the highest proportions of in-patients and patients with psychotic disorder reporting higher frequencies of undetected PTSD. Undetected PTSD is common in secondary care, even if the true value is at the lower limit of the estimates reported here. Trials examining the impact of routine screening for PTSD are required to determine whether such programmes should be standard procedure for all mental health services. Declaration of interest None.

    In recent years, use of plants for remediation of contaminated soils, especially removal of heavy metals, is considered. The current study tends to investigate the removal of lead and nickel ions by the Convolvulus tricolor (CTC), was grown for 30 days in different concentrations of lead and nickel ions. Then concentration of them in soil and different organs of the plant was measured by atomic absorption spectrometry. The highest absorbed of them occurred in concentration 0.001N, which highest Pb(2+) accumulation is in the aerial parts of the plant: leaf > stem > root and for Ni(2)+: root > stem > leaf. No ion was observed into the flowers and nickel ion absorption is more of lead ion in different plant organs of CTC. The experimental isotherm data were investigated using isotherms of Langmuir, Freundlich, BET, Temkin and Dubinin-Radushkevich (DRK). The correlation coefficient for all of them is calculated that show the best correlation coefficient for Ni(2+) adsorption is obtained BET model, whereas for Pb(2+) adsorption in root is Freundlich model but for its leaf and stem is BET model. The results show, CTC is suitable for Pb(2+) and Ni(2+) and this technique is in-situ method, simple, and low cost.

  10. Deciphering the enigma of undetected species, phylogenetic, and functional diversity based on Good-Turing theory.

    Estimating the species, phylogenetic, and functional diversity of a community is challenging because rare species are often undetected, even with intensive sampling. The Good-Turing frequency formula, originally developed for cryptography, estimates in an ecological context the true frequencies of rare species in a single assemblage based on an incomplete sample of individuals. Until now, this formula has never been used to estimate undetected species, phylogenetic, and functional diversity. Here, we first generalize the Good-Turing formula to incomplete sampling of two assemblages. The original formula and its two-assemblage generalization provide a novel and unified approach to notation, terminology, and estimation of undetected biological diversity. For species richness, the Good-Turing framework offers an intuitive way to derive the non-parametric estimators of the undetected species richness in a single assemblage, and of the undetected species shared between two assemblages. For phylogenetic diversity, the unified approach leads to an estimator of the undetected Faith's phylogenetic diversity (PD, the total length of undetected branches of a phylogenetic tree connecting all species), as well as a new estimator of undetected PD shared between two phylogenetic trees. For functional diversity based on species traits, the unified approach yields a new estimator of undetected Walker et al.'s functional attribute diversity (FAD, the total species-pairwise functional distance) in a single assemblage, as well as a new estimator of undetected FAD shared between two assemblages. Although some of the resulting estimators have been previously published (but derived with traditional mathematical inequalities), all taxonomic, phylogenetic, and functional diversity estimators are now derived under the same framework. All the derived estimators are theoretically lower bounds of the corresponding undetected diversities; our approach reveals the sufficient conditions under

There was no evidence of effect of sex, clinical status, current immune status, and changes in treatment regimen. Treatment adherence gave the largest effect. Motivational interventions directed at adherence may improve treatment effectiveness.

  12. Deutsch's CTC Model and its Implications for the Foundations of Quantum Theory

    Science.gov (United States)

    Dunlap, Lucas

    This dissertation is an exploration of several issues surrounding David Deutsch's CTC model first introduced in his 1991 paper "Quantum Mechanics Near Closed Timelike Lines". Deutsch developed his model to account for the effects of quantum theory, which had been left out of classical discussions of time travel paradoxes. Deutsch's formulation of his model in terms of quantum computational circuits lends itself to being adopted in the quantum information community. The dissertation argues that the adoption of the D-CTC model entails the existence of Nonlocal Signaling, which is in conflict with a fundamental principle of the quantum information approach. In order to motivate this argument, in Chapter 2 I introduce a distinction between Nonlocal Signaling, and Superluminal Information Transfer. In the latter case, a carrier of information physically traverses the space between the distant communicating parties faster than the speed of light. Exploiting quantum entanglement to signal, however, need not have this feature. I term this Nonlocal Signaling. Chapter 3 is where I present the argument that D-CTCs entail Nonlocal Signaling, and examine the controversy surrounding this and related results. I argue that the resistance to these kinds of predictions in the literature is motivated by a commitment to the principles of quantum information theory, which are inappropriately applied here. Chapters 4 and 5 examine details of Deutsch's model. Chapter 4 argues that it presupposes a significant metaphysical picture that, when explicitly stated, makes a much less comfortable fit between D-CTCs and quantum information theory. Chapter 5 argues that, because of Deutsch's commitment to this metaphysical picture, he is committed to the existence of physical situations that are in every way indistinguishable from the paradoxes he attempts to rule out by adopting the model in the first place. In Chapter 6, I make some observations about the relationship between the quantum

    This study aimed to evaluate the prevalence of colonic diverticula according to age, gender, distribution, disease extension and symptoms with CT colonography (CTC). The study population included 1091 consecutive patients who underwent CTC. Patients with diverticula were retrospectively stratified according to age, gender, clinical symptoms and colonic segment involvement. Extension of colonic diverticula was evaluated using a three-point quantitative scale. Using this data, a multivariate regression analysis was applied to investigate the existence of any correlation among variables. Colonic diverticula were observed in 561 patients (240 men, mean age 68 ± 12 years). Symptomatic uncomplicated diverticular disease (SUDD) was present in 47.4 % of cases. In 25.6 % of patients ≤40 years, at least one diverticulum in the colon was observed. Prevalence of right-sided diverticula in patients >60 years was 14.2 % in caecum and 18.5 % in ascending colon. No significant difference was found between symptomatic and asymptomatic patients regarding diverticula prevalence and extension. No correlation was present between diverticula extension and symptoms. The incidence of colonic diverticula appears to be greater than expected. Right colon diverticula do not appear to be an uncommon finding, with their prevalence increasing with patient age. SUDD does not seem to be related to diverticula distribution and extension.

  15. Reduction of false positives by extracting fuzzy rules from data for polyp detection in CTC scans

    This paper presents an adaptive neural network based Fuzzy Inference System (ANFIS) to reduce the false positive (FP) rate of detected colonic polyps in Computed Tomography Colonography (CTC) scans. Extracted fuzzy rules establish linguistically interpretable relationships in the data that are easy to understand, validate, and extend. The system takes several features identified from regions extracted by a segmentation algorithm and decides whether the regions are true polyps. In the training phase, subtractive clustering is used to down-sample the negative regions in order to get balanced data. The rule extraction method is based on estimating clusters in the data using the subtractive clustering algorithm; each cluster obtained corresponds to a fuzzy rule that maps a region in the input space to an output class. After the number of rules and initial rule parameters are obtained by cluster estimation, the rule parameters are optimized using a hybrid learning algorithm which is a combination of least-squares estimation with back propagation. The evolved Sugeno-type FIS has been tested on a total of 129 scans with 99 polyps of sizes 5-15 mm by experienced radiologists. The results indicate that for 93% detection sensitivity (on polyps), the evolved FIS method is able to remove 88% of FPs generated by the segmentation algorithm leaving 7.5 FP per scan. The high sensitivity rate of our results show the promise of neuro-fuzzy classifiers as an aid for interpreting CTC examinations.

    and misassignment may lead to local dose errors on the order of 10%. A novel algorithm, CTC-ask, is presented in this study. It enables locally confined constraints for the media assignment and is independent of the number of media used for the conversion of CT number to density. MC compatible phantoms were...... generated for two clinical cases using a CT-conversion scheme implemented in both CTC-ask and the DICOM-RT toolbox. Full MC dose calculation was subsequently conducted and the resulting dose distributions were compared. The DICOM-RT toolbox inaccurately assigned lung in 9.9% and 12.2% of the voxels located...... outside of the lungs for the two cases studied, respectively. This was completely avoided by CTC-ask. CTC-ask is able to reduce anatomically irrational media assignment. The CTC-ask source code can be made available upon request to the authors....

    A forethought about the organization and counter-actions to follow in case of reactor accident crisis has been carried out by the French nuclear partners (operators and public authorities). This forethought has led to the creation of a Crisis National Organization which determines the responsibilities and missions of each partner. Inside this organization, the IPSN (Institute for Nuclear Protection and Safety) plays the role of technical support and expert for the Safety Authority. To carry out these missions, a Crisis Technical Center has been installed for ten years in Fontenay-aux-Roses CEA center. This document is a presentation of the CTC activities and evolutions in the framework of the existing National Organization. The main axes along which this activity will evolve in the future are summarized. (J.S.). 3 figs

    In [1] K.A.S. Abdel-Ghaffar derives a lower bound on the probability of undetected error for unrestricted codes. The proof relies implicitly on the binomial moments of the distance distribution of the code. The authors use the fact that these moments count the size of subcodes of the code to give a very simple proof of the bound in [1] by showing that it is essentially equivalent to the Singleton bound. They discuss some combinatorial connections revealed by this proof. They also discuss some improvements of this bound. Finally, they analyze asymptotics. They show that an upper bound on the undetected error exponent that corresponds to the bound of [1] improves known bounds on this function.

    Pancreatic cancer remains one of the most difficult cancers to treat with the poorest prognosis. The key to improving survival rates in this disease is early detection and monitoring of disseminated and residual disease. However, this is hindered due to lack reliable diagnostic and predictive markers which mean that the majority of patients succumb to their condition within a few months. We present a pilot study of the detection circulating free DNA (cfDNA) combined with tumor specific mutation detection by digital PCR as a novel minimally invasive biomarker in pancreatic ductal adenocarcinoma (PDAC). This was compared to the detection of CTC by the CellSearch® system and a novel CTC enrichment strategy based on CD45 positive cell depletion. The aim of the study was to assess tumor specific DNA detection in plasma and CTC detection as prognostic markers in PDAC. We detected KRAS mutant cfDNA in 26 % of patients of all stages and this correlated strongly with Overall Survival (OS), 60 days (95 % CI: 19–317) for KRAS mutation positive vs 772 days for KRAS mutation negative (95 % CI: 416–1127). Although, the presence of CTC detected by the CellSearch® system did correlate significantly with OS, 88 days (95 % CI: 27–206) CTC positive vs 393 days CTC negative (95 % CI: 284–501), CTC were detected in only 20 % of patients, the majority of which had metastatic disease, whereas KRAS mutant cfDNA was detected in patients with both resectable and advanced disease. Tumor specific cfDNA detection and CTC detection are promising markers for the management of patients with PDAC, although there is a need to validate these results in a larger patient cohort and optimize the detection of CTC in PDAC by applying the appropriate markers for their detection.

    Full Text Available Abstract Background There have been no previous studies of the long-term survival and temporal changes in plasma viral load among HIV-2 infected subjects. Methods 133 HIV-2 infected and 158 HIV-uninfected subjects from a rural area in North-west Guinea-Bissau, West Africa were enrolled into a prospective cohort study in 1991 and followed-up to mid-2009. Data were collected on four occasions during that period on HIV antibodies, CD4% and HIV-2 plasma viral load. Results Median age (interquartile range [IQR] of HIV-2 infected subjects at time of enrollment was 47 (36, 60 years, similar to that of HIV-uninfected control subjects, 49 (38, 62 (p = 0.4.

    Purpose To compare total colonic gas volume and segmental luminal distention according to patient position at CT colonography (CTC), and determine which two views should constitute the routine protocol. Methods Volumetric analysis was retrospectively performed on CTC examinations from 146 adults (mean age, 59.2 years; 81M/65F; mean BMI, 30.9) where supine, prone, and right lateral decubitus series were sequentially obtained using continuous low-pressure CO2 insufflation. Total colonic gas volumes were assessed using a novel automated volumetric tool. In addition, two radiologists scored distention by segment using a 4-point scale (4=Optimal/3=Adequate/2=Inadequate/1=Collapsed). Results Mean colonic gas volume (±SD) for supine, prone, and decubitus positioning was 1,617±567 ml, 1441±505 ml, and 1901±627 ml, respectively (pvolumetric analysis provides for rapid objective assessment of colonic distention.

    Recent studies reporting hundreds, to thousands, of circulating tumor cells (CTCs) in the blood of cancer patients have raised questions regarding the prevalence of CTCs, as enumerated by the CellSearch(®) CTC Test. Although CellSearch has been shown to consistently detect clinically relevant CTCs; the ability to only capture EpCAM positive cells has led to speculation that it captures limited subsets of CTCs. In contrast, alternative approaches to CTC isolation are often cited as capturing large numbers of CTCs from patient blood. Not surprisingly the number of cells isolated by alternative approaches show poor correlations when compared to CellSearch, even when accounting for EpCAM presence or absence. In an effort to address this discrepancy, we ran an exploratory method comparison study to characterize and compare the CTC subgroups captured from duplicate blood samples from 30 breast and prostate cancer patients using a microfiltration system (CellSieve™) and CellSearch. We then categorized the CellSieve Cytokeratin(CK)+/CD45-/DAPI+ cells into five morphologically distinct subpopulations for correlative analysis. Like other filtration techniques, CellSieve isolated greater numbers of CK+/CD45- cells than CellSearch. Furthermore, analysis showed low correlation between the total CK+/CD45- cells captured by these two assays, regardless of EpCAM presence. However, subgrouping of CK+/CD45-/DAPI+ cells based on distinct cytokeratin staining patterns and nuclear morphologies elucidated a subpopulation correlative to CellSearch. Using method comparison analyses, we identified a specific CTC morphology which is highly correlative between two distinct capture methods. These data suggests that although various morphologic CTCs with similar phenotypic expressions are present in the blood of cancer patients, the clinically relevant cells isolated by CellSearch can potentially be identified using non-EpCAM dependent isolation. © 2014 The Authors.

    Management of metastatic disease in oncology includes monitoring of therapy response principally by imaging techniques like CT scan. In addition to some limitations, the irruption of liquid biopsy and its application in personalized medicine has encouraged the development of more efficient technologies for prognosis and follow-up of patients in advanced disease. PrediCTC constitutes a panel of genes for the assessment of circulating tumor cells (CTC) in metastatic colorectal cancer patients, with demonstrated improved efficiency compared to CT scan for the evaluation of early therapy response in a multicenter prospective study. In this work, we designed and developed a technology transfer strategy to define the market opportunity for an eventual implementation of PrediCTC in the clinical practice. This included the definition of the regulatory framework, the analysis of the regulatory roadmap needed for CE mark, a benchmarking study, the design of a product development strategy, a revision of intellectual property, a cost-effectiveness study and an expert panel consultation. The definition and analysis of an appropriate technology transfer strategy and the correct balance among regulatory, financial and technical determinants are critical for the transformation of a promising technology into a viable technology, and for the decision of implementing liquid biopsy in the monitoring of therapy response in advanced disease.

    Cerebro-retinal microangiopathy with calcifications and cysts (CRMCC) or Coats plus syndrome is a pleiotropic disorder affecting the eyes, brain, bone and gastrointestinal tract. Its primary pathogenesis involves small vessel obliterative microangiopathy. Recently, autosomal recessively inherited mutations in CTC1 have been reported in CRMCC patients. We herein report an adolescent referred to our hospital following new seizures in a context of an undefined multisystem disorder. Cerebral imaging disclosed asymmetrical leukopathy, intracranial calcifications and cysts. In addition, he presented other typical CRMCC features i.e. a history of intrauterine growth retardation, skeletal demineralization and osteopenia, bilateral exudative vitreo-retinopathy reminiscent of Coats disease, recurrent gastrointestinal hemorrhages secondary to watermelon stomach and variceal bleeding of the esophagus due to idiopathic portal hypertension and telangiectatic and angiodysplasic changes in the small intestine and colon, and anemia due to recurrent bleeding and bone marrow abnormalities. The patient was diagnosed with Coats plus syndrome. CTC1 gene screening confirmed the diagnosis with the identification of heterozygous deleterious mutations. CRMCC due to CTC1 mutations has a broad clinical expressivity. Our case report illustrates the main possible associated phenotypes and their complications, demonstrating the need for a careful etiological search in order to initiate appropriate therapeutic and preventive measures.

    Maintaining functional telomeres is important for long-term proliferation of cells. About 15% of cancer cells are telomerase-negative and activate the alternative-lengthening of telomeres (ALT) pathway to maintain their telomeres. Recent studies have shown that the human CTC1/STN1/TEN1 complex (CST) plays a multi-faceted role in telomere maintenance in telomerase-expressing cancer cells. However, the role of CST in telomere maintenance in ALT cells is unclear. Here, we report that human CST forms a functional complex localizing in the ALT-associated PML bodies (APBs) in ALT cells throughout the cell cycle. Suppression of CST induces telomere instabilities including telomere fragility and elevates telomeric DNA recombination, leading to telomere dysfunction. In addition, CST deficiency significantly diminishes the abundance of extrachromosomal circular telomere DNA known as C-circles and t-circles. Suppression of CST also results in multinucleation in ALT cells and impairs cell proliferation. Our findings imply that the CST complex plays an important role in regulating telomere maintenance in ALT cells. Copyright © 2017 Elsevier Inc. All rights reserved.

    A search is presented for exotic decays of a Higgs boson into undetectable particles and one or two isolated photons in pp collisions at a center-of-mass energy of 8 TeV. The data correspond to an integrated luminosity of up to 19.4 fb$^{-1}$ collected with the CMS detector at the LHC. Higgs bosons produced in gluon-gluon fusion and in association with a Z boson are investigated, using models in which the Higgs boson decays into a gravitino and a neutralino or a pair of neutralinos, followed by the decay of the neutralino to a gravitino and a photon. The selected events are consistent with the background-only hypothesis, and limits are placed on the product of cross sections and branching fractions. Assuming a standard model Higgs boson production cross-section, a 95% confidence level upper limit is set on the branching fraction of a 125 GeV Higgs boson decaying into undetectable particles and one or two isolated photons as a function of the neutralino mass. For neutralino masses from 1 to 120 GeV an upper li...

    With the availability of the highly sensitive β-human chorionic gonadotropin (β-hCG) assays, all pregnancies, including ectopic pregnancies (EP), are expected to have detectable serum β-hCG at 4 weeks' gestation or 9 days following blastocyst transfer. To our knowledge, this is the first report of a woman who underwent in vitro fertilization, had undetectable serum β-hCG 9 days after blastocyst transfer, and was then diagnosed with a ruptured abdominal EP and intra-abdominal bleeding 19 days later. This case highlights that the rise in serum β-hCG might be delayed in abdominal EP compared to intrauterine pregnancy. This delay should raise the suspicion for EP, thus meriting close monitoring. Moreover, in the absence of menstruation, an undetectable serum β-hCG 9 days post-blastocyst transfer should prompt β-hCG measurement in 2-3 days to avoid the misdiagnosis of an EP. © 2016 Japan Society of Obstetrics and Gynecology.

    Background HIV patients on suppressive antiretroviral therapy have undetectable viremia making it impossible to screen plasma HIV tropism if regimen change is required during suppression. We investigated the prevalence and predictors of tropism switch from CCR5-using (“R5”) to non-CCR5-using (“non-R5”) before and after viral suppression in the initially therapy-naïve HOMER cohort from British Columbia, Canada. Methods We compared pre-therapy and post-suppression viral genotypic tropism in patients who initiated on PI/NNRTI-based antiretroviral regimens between 1996-1999 (n = 462). Virologic suppression was defined as having two consecutive viral loads of tropism was inferred by V3-loop-population-sequencing and geno2pheno[coreceptor] with cutoff at 5.75% false positive rate (FPR). Results When virologic suppression was defined as two-consecutive viral loads tropism switches in plasma virus after undetectable viremia were relatively rare events especially among patients with higher CD4 counts during virologic suppression. Our study supports the use of pre-suppression tropism results if maraviroc is being considered during virologic suppression in this subgroup of patients. PMID:24905411

    This article points to a long lasting problem in space research and cosmology, the problem of undetected signs of non terrestrial life and civilizations. We intentionally avoid the term extraterrestrial as we consider other possibilities that may arise but not fall strictly within the extraterrestrial scope. We discuss the role of new physics including dark matter and string theory in the search for life and other non terrestrial intelligence. A new classification for non terrestrial civilizations with three types and five dimensions is also provided. We also explain how our own neurophysiology, psychology and consciousness can play a major role in this search of non terrestrial civilizations task and how they have been neglected up to this date. To test this, 137 adults were evaluated using the cognitive reflection test, an attention/awareness questionnaire and a visuospatial searching task with aerial view images to determine the presence of inattentional blindness.

    The elderly population in Malaysia is growing rapidly. Some of the most vulnerable are in residential care. Research is needed into the characteristics of this population to aid clinicians and policy makers in addressing the needs of this group. This observational, cross-sectional study aims to determine prevalence of undetected cognitive impairment and depression in elderly care home residents in Malaysia. One hundred and sixty-seven people over 60 years of age living in a state run residential home were interviewed. Validated assessment tools were used to measure dependency, cognitive impairment and depression. The prevalence of probable dementia is 36.5%, with increasing prevalence with age and level of dependence. Prevalence of depression is 67.0% (major depression 13.2%), with more depression in males and in the Indian population. None of the identified cases had been previously investigated or treated for dementia or depression.

    The aim of this study was to determine how monetary motivations influence decision making of humans performing as security analysts and hackers in a cybersecurity game. Cyberattacks are increasing at an alarming rate. As cyberattacks often cause damage to existing cyber infrastructures, it is important to understand how monetary rewards may influence decision making of hackers and analysts in the cyber world. Currently, only limited attention has been given to this area. In an experiment, participants were randomly assigned to three between-subjects conditions ( n = 26 for each condition): equal payoff, where the magnitude of monetary rewards for hackers and defenders was the same; rewarding hacker, where the magnitude of monetary reward for hacker's successful attack was 10 times the reward for analyst's successful defense; and rewarding analyst, where the magnitude of monetary reward for analyst's successful defense was 10 times the reward for hacker's successful attack. In all conditions, half of the participants were human hackers playing against Nash analysts and half were human analysts playing against Nash hackers. Results revealed that monetary rewards for human hackers and analysts caused a decrease in attack and defend actions compared with the baseline. Furthermore, rewarding human hackers for undetected attacks made analysts deviate significantly from their optimal behavior. If hackers are rewarded for their undetected attack actions, then this causes analysts to deviate from optimal defend proportions. Thus, analysts need to be trained not become overenthusiastic in defending networks. Applications of our results are to networks where the influence of monetary rewards may cause information theft and system damage.

    Full Text Available Abstract Background Adenovirus (Ad, associated with significant morbidity, has no topical treatment. A leading CTC compound (CTC-96, a CoIII chelate, was found to have potent in vitro and in vivo antiviral efficacy against herpes viruses. In this study CTC-96 is being tested for possible anti-Adenovirus activity. Methods The biological anti-adenovirus activity of CTC-96 in concentrations from 5 to 250 ug/ml, was evaluated initially by viral inactivation (viral exposure to CTC-96 followed by dilution and inoculation of cells, virucidal (viral exposure to CTC-96 and inoculation of cells without dilution and antiviral (effect of CTC-96 on previously adsorbed virus plaque assays on HeLa (human cervical carcinoma, A549 (human lung carcinoma and SIRC (rabbit corneal cells.

    One of the building blocks in Monte Carlo (MC) treatment planning is to convert patient CT data to MC compatible phantoms, consisting of density and media matrices. The resulting dose distribution is highly influenced by the accuracy of the conversion. Two major contributing factors are precise conversion of CT number to density and proper differentiation between air and lung. Existing tools do not address this issue specifically. Moreover, their density conversion may depend on the number of media used. Differentiation between air and lung is an important task in MC treatment planning and misassignment may lead to local dose errors on the order of 10%. A novel algorithm, CTC-ask, is presented in this study. It enables locally confined constraints for the media assignment and is independent of the number of media used for the conversion of CT number to density. MC compatible phantoms were generated for two clinical cases using a CT-conversion scheme implemented in both CTC-ask and the DICOM-RT toolbox. Full MC dose calculation was subsequently conducted and the resulting dose distributions were compared. The DICOM-RT toolbox inaccurately assigned lung in 9.9% and 12.2% of the voxels located outside of the lungs for the two cases studied, respectively. This was completely avoided by CTC-ask. CTC-ask is able to reduce anatomically irrational media assignment. The CTC-ask source code can be made available upon request to the authors. (note)

    Full Text Available Robotics science has evolved significantly, driven by rapid advances in computer and sensor technology; and theoretical advances in control and computer vision. These development make widespread use of robot manipulators in industrial environments. Major problem in controlling a robot manipulator is to control the robot in order to achieve the desired position. Therefore the design issue of the robot control is to choose the right type controller. Computed Torque Controller (CTC is a powerful nonlinear controllers are widely used in the control of robot manipulators. CTC controller is designed based on feedback linearization and the required torque of the robot arm by using a nonlinear feedback control law. Simulation is done by providing joint trajectory from point to point. The simulation results show that the PD-Fuzzy-CTC controller is able to follow the joint trajectory with The RMSE value of the joint angle position of PD-Fuzzy-CTC controller is 10 times smaller than that of the PD-CTC controller with the end-effector position accuracy is 0.1 mm.

    1998-03-01

    This report summarizes results and insights from a preliminary survey of events involving undetected, latent failures of safety-related systems. The survey was limited to events where mispositioned equipment (e.g., valves, switches) remained undetected, thus rendering standby equipment or systems unavailable for short or long time periods. Typically, these events were symptoms of underlying latent errors (e.g., design errors, procedure errors, unanalyzed safety conditions) and programmatic errors. The preliminary survey identified well over 300 events. Of these, 95 events are documented in this report. Events involving mispositioned equipment are commonplace. Most events are discovered soon after occurrence, however. But as evidenced by the survey results, some events remained undetected beyond several shift changes. The recommendations developed by the survey emphasize the importance of applying modern root cause analysis techniques to the event analysis to ensure that the causes and implications of occurred events are fully understood

Among sow herds with production of weaners or growers, we...... with MRDT104 from 1 August 2001 till 31 July 2002 (90% CI [63, 228]). In comparison, 33 (32%) infected herds were detected in this period. The predicted proportion of undetected herds varied considerably with herd type. We infer that the proportion of detected MRDT104 infected herds depended...

    Full Text Available En 1949, los Estado Unidos, como parte de su política anticomunista y antisindical durante la Guerra Fría, presionaron al Ministerio del Trabajo de Colombia, requiriéndole que removiese a aquellos líderes de la Confederación de Trabajadores de Colombia (CTC que el Departamento de Estado norteamericano consideraba comunistas. Ya que el FBI tenía agentes en Colombia recogiendo información sobre las vidas y actividades de los "comunistas" -reales o imaginarios-, era fácil para los norteamericanos señalar a quienes querían ver perseguidos. El Ministerio conservador no quiso ayudar directamente a la Embajada, argumentando con buenas razones, que el Partido Liberal era el que tenía la influencia sobre las facciones "moderadas'' dentro de la CTC. El embajador Willard Beaulac se puso entonces en contacto con el político Carlos Lleras Restrepo y le solicitó que se encargase de coordinar la expulsión de los líderes izquierdistas de la Confederación.

    Purpose: To evaluate the efficacy of postoperative adjuvant radiotherapy (RT) for positive resection margin and/or pathologic T3 (pT3) adenocarcinoma of the prostate with undetectable postoperative prostate-specific antigen (PSA) levels. Methods and materials: We retrospectively analyzed 125 patients with a positive resection margin and/or pT3 adenocarcinoma of the prostate who had undetectable postoperative serum PSA levels after radical prostatectomy. Seventy-three patients received postoperative adjuvant RT and 52 did not. Follow-up ranged from 1.5 to 12.0 years (median 4.2 for the irradiated group and 4.9 for the nonirradiated group). PSA outcome was available for all patients. Freedom from failure was defined as the maintenance of a serum PSA level of ≤0.2 ng/mL, as well as the absence of clinical local recurrence and distant metastasis. Results: No difference was found in the 5-year actuarial overall survival between the irradiated and nonirradiated group (94% vs. 95%). However, patients receiving adjuvant RT had a statistically superior 5-year actuarial relapse-free rate, including freedom from PSA failure, compared with those treated with surgery alone (88% vs. 65%, p=0.0013). In the irradiated group, 8 patients had relapse with PSA failure alone. None had local or distant recurrence. In the nonirradiated group, 15, 1, and 2 had PSA failure, local recurrence, and distant metastasis, respectively. On Cox regression analysis, pre-radical prostatectomy PSA level and adjuvant RT were statistically significant predictive factors for relapse, and Gleason score, extracapsular invasion, and resection margin status were not. There was a suggestion that seminal vesicle invasion was associated with an increased risk of relapse. The morbidity of postoperative adjuvant RT was acceptable, with only 2 patients developing Radiation Therapy Oncology Group Grade 3 genitourinary complications. Adjuvant RT had a minimal adverse effect on urinary continence and did not cause

    The time course of human papillomavirus (HPV) DNA clearance was studied in patients with carcinoma of the cervix during follow-up after primary radical radiotherapy (RT). This study investigated the relationship between timing of HPV clearance and RT effectiveness. A total of 71 consecutive patients who were treated for cervical cancer with primary radical radiotherapy and high-dose rate intracavitary brachytherapy with or without chemotherapy were enrolled in the study. Samples for HPV DNA examination were taken before (1) treatment, (2) every brachytherapy, and (3) every follow-up examination. The times when HPV DNA was undetected were analyzed for association with recurrence-free survival. HPV DNA was not detected in 13 patients (18 %) before RT. Of the 58 patients with HPV DNA detected before treatment, HPV DNA was not detected in 34 % during treatment and in 66 % after the treatment. Within 6 months after RT, HPV DNA was detected in 0 % of all patients. The patients were followed up for a median period of 43 months (range 7-70 months). In all, 20 patients were found to develop recurrence. The 3-year cumulative disease-free survival (DFS) rate was 71 ± 5.4 % for all 71 patients. In multivariate analysis, DFS was significantly associated with HPV (detected vs. not detected) with a hazard ratio of 0.07 (95 % confidence interval 0.008-0.6, p = 0.009). In this study, patients in whom HPV was not detected had the worst prognosis. Six months after RT, HPV DNA was detected in 0 % of the patients. Patients in whom HPV DNA could not be detected before treatment need careful follow-up for recurrence and may be considered for additional, or alternative treatment. (orig.) [de

  4. Family Medicine Residents' Performance with Detected Versus Undetected Simulated Patients Posing as Problem Drinkers

    Mark B. Sobell, PhD

    2004-01-01

    Full Text Available Background: Simulated patients are commonly used to evaluate medical trainees. Unannounced simulated patients provide an accurate measure of physician performance. Purpose: To determine the effects of detection of SPs on physician performance, and identify factors leading to detection. Methods: Fixty-six family medicine residents were each visited by two unannounced simulated patients presenting with alcohol-induced hypertension or insomnia. Residents were then surveyed on their detection of SPs. Results: SPs were detected on 45 out of 104 visits. Inner city clinics had higher detection rates than middle class clinics. Residents’ checklist and global rating scores were substantially higher on detected than undetected visits, for both between-subject and within-subject comparisons. The most common reasons for detection concerned SP demographics and behaviour; the SP “did not act like a drinker” and was of a different social class than the typical clinic patient. Conclusions: Multi-clinic studies involving residents experienced with SPs should ensure that the SP role and behavior conform to physician expectations and the demographics of the clinic. SP station testing does not accurately reflect physicians’ actual clinical behavior and should not be relied on as the primary method of evaluation. The study also suggests that physicians’ poor performance in identifying and managing alcohol problems is not entirely due to lack of skill, as they demonstrated greater clinical skills when they became aware that they were being evaluated. Physicians’ clinical priorities, sense of responsibility and other attitudinal determinants of their behavior should be addressed when training physicians on the management of alcohol problems.

    The objective was to determine clinical consequences of anti-D and non-D antibodies undetected at first-trimester screening for infant or fetus. This retrospective cohort study included all pregnant women with red blood cell (RBC) antibodies who were tested between 1993 and 2008. Data were obtained from the forms for tracking immunization at the transfusion department. Each form was analyzed for three data sets: the order of screening at which the antibodies were detected (initial or repeated screening), the order of pregnancy (first pregnancy or higher), and whether the antibodies caused severe hemolytic disease of fetus and newborn (HDFN). In D- women, anti-D was detected in 1.3% of cases. The anti-D was undetected in 72 (37%) cases on the first-trimester screening, of which eight cases were complicated by severe HDFN. In this group, three patients were primigravidae. An overall non-D incidence of 0.2% was observed. In 16 cases, non-D were undetected on the first-trimester screening (10 anti-c, two anti-E, two anti-C, one anti-S, and one case of anti-Rh17). Non-D antibodies undetected on initial screening caused 11 cases of severe HDFN (27% of all severe non-D HDFN). Ten of them were in multiparous women. Seven of 11 cases with severe HDFN that were missed were caused by anti-c. The third-trimester screening may detect RBC antibodies that were not present or detected on the first-trimester screening. Such screening may be especially relevant in D+ multiparous women due to the risk of HDFN. © 2010 American Association of Blood Banks.

  6. Timing of intermittent seminal HIV-1 RNA shedding in patients with undetectable plasma viral load under combination antiretroviral therapy.

    Full Text Available It was demonstrated that combination antiretroviral therapy (cART reduces the HIV-1 viral load (VL in the blood and the seminal compartment. Some studies have reported that the seminal HIV-1 VL is undetectable in individuals with an undetectable blood plasma viral load (bpVL under cART. However, some recent studies have demonstrated that seminal HIV-1 RNA may still be detected, and potentially infectious, even in the case of an undetectable bpVL. The aim of this retrospective study was to determine the detection rate of a seminal VL and whether shedding could be intermittent over a very short time. From January 2006 to December 2011, 88 HIV-1 infected men, enrolled in an Assisted Reproduction program, provided 306 semen samples, corresponding to 177 frozen sperm samples (two samples delivered at a one-hour interval (n = 129 or one sample (n = 48. All enrolled men were under cART, with an undetectable bpVL for more than 6 months. HIV-1 RNA was quantified in seminal plasma using a Roche COBAS Ampliprep COBAS TaqMan HIV-1 test. Seminal HIV-1 RNA was detected in 23 samples (7.5% from 17 patients (19.3%. This detection rate was stable over years. With regards to the freezing of two samples delivered at a one-hour interval, the proportion of discordance between the first and second samples was 9.3% (12/129. Our results confirm the intermittent shedding of HIV-1 in semen. While this finding has been shown by studies examining longer time intervals, to our knowledge, this has never been demonstrated over such a short time interval.

    It was demonstrated that combination antiretroviral therapy (cART) reduces the HIV-1 viral load (VL) in the blood and the seminal compartment. Some studies have reported that the seminal HIV-1 VL is undetectable in individuals with an undetectable blood plasma viral load (bpVL) under cART. However, some recent studies have demonstrated that seminal HIV-1 RNA may still be detected, and potentially infectious, even in the case of an undetectable bpVL. The aim of this retrospective study was to determine the detection rate of a seminal VL and whether shedding could be intermittent over a very short time. From January 2006 to December 2011, 88 HIV-1 infected men, enrolled in an Assisted Reproduction program, provided 306 semen samples, corresponding to 177 frozen sperm samples (two samples delivered at a one-hour interval (n = 129) or one sample (n = 48)). All enrolled men were under cART, with an undetectable bpVL for more than 6 months. HIV-1 RNA was quantified in seminal plasma using a Roche COBAS Ampliprep COBAS TaqMan HIV-1 test. Seminal HIV-1 RNA was detected in 23 samples (7.5%) from 17 patients (19.3%). This detection rate was stable over years. With regards to the freezing of two samples delivered at a one-hour interval, the proportion of discordance between the first and second samples was 9.3% (12/129). Our results confirm the intermittent shedding of HIV-1 in semen. While this finding has been shown by studies examining longer time intervals, to our knowledge, this has never been demonstrated over such a short time interval.

    Objectives: To evaluate the efficiency and feasibility of microwave (MW) ablation assisted by a real-time virtual navigation system for hepatocellular carcinoma (HCC) undetectable by conventional ultrasonography. Methods: 18 patients with 18 HCC nodules (undetectable on conventional US but detectable by intravenous contrast-enhanced CT or MRI) were enrolled in this study. Before MW ablation, US images and MRI or CT images were synchronized using the internal markers at the best timing of the inspiration. Thereafter, MW ablation was performed under real-time virtual navigation system guidance. Therapeutic efficacy was assessed by the result of contrast-enhanced imagings after the treatment. Results: The target HCC nodules could be detected with fusion images in all patients. The time required for image fusion was 8–30 min (mean, 13.3 ± 5.7 min). 17 nodules were successfully ablated according to the contrast enhanced imagings 1 month after ablation. The technique effectiveness rate was 94.44% (17/18). The follow-up time was 3–12 months (median, 6 months) in our study. No severe complications occurred. No local recurrence was observed in any patients. Conclusions: MW ablation assisted by a real-time virtual navigation system is a feasible and efficient treatment of patients with HCC undetectable by conventional ultrasonography.

  9. Beliefs about lying and spreading of dishonesty: undetected lies and their constructive and destructive social dynamics in dice experiments.

    Directory of Open Access Journals (Sweden)

    Heiko Rauhut

    Full Text Available Field experiments have shown that observing other people littering, stealing or lying can trigger own misconduct, leading to a decay of social order. However, a large extent of norm violations goes undetected. Hence, the direction of the dynamics crucially depends on actors' beliefs regarding undetected transgressions. Because undetected transgressions are hardly measureable in the field, a laboratory experiment was developed, where the complete prevalence of norm violations, subjective beliefs about them, and their behavioral dynamics is measurable. In the experiment, subjects could lie about their monetary payoffs, estimate the extent of liars in their group and make subsequent lies contingent on information about other people's lies. Results show that informed people who underestimate others' lying increase own lying more than twice and those who overestimate, decrease it by more than half compared to people without information about others' lies. This substantial interaction puts previous results into perspective, showing that information about others' transgressions can trigger dynamics in both directions: the spreading of normative decay and restoring of norm adherence.

    The time course of human papillomavirus (HPV) DNA clearance was studied in patients with carcinoma of the cervix during follow-up after primary radical radiotherapy (RT). This study investigated the relationship between timing of HPV clearance and RT effectiveness. A total of 71 consecutive patients who were treated for cervical cancer with primary radical radiotherapy and high-dose rate intracavitary brachytherapy with or without chemotherapy were enrolled in the study. Samples for HPV DNA examination were taken before (1) treatment, (2) every brachytherapy, and (3) every follow-up examination. The times when HPV DNA was undetected were analyzed for association with recurrence-free survival. HPV DNA was not detected in 13 patients (18 %) before RT. Of the 58 patients with HPV DNA detected before treatment, HPV DNA was not detected in 34 % during treatment and in 66 % after the treatment. Within 6 months after RT, HPV DNA was detected in 0 % of all patients. The patients were followed up for a median period of 43 months (range 7-70 months). In all, 20 patients were found to develop recurrence. The 3-year cumulative disease-free survival (DFS) rate was 71 ± 5.4 % for all 71 patients. In multivariate analysis, DFS was significantly associated with HPV (detected vs. not detected) with a hazard ratio of 0.07 (95 % confidence interval 0.008-0.6, p = 0.009). In this study, patients in whom HPV was not detected had the worst prognosis. Six months after RT, HPV DNA was detected in 0 % of the patients. Patients in whom HPV DNA could not be detected before treatment need careful follow-up for recurrence and may be considered for additional, or alternative treatment. (orig.)

    This white paper investigates the potential integration of the CTC work breakdown structure numbering scheme with a plant/equipment numbering system (PNS), or alternatively referred to in industry as a reference designation system (RDS). Ideally, the goal of such integration would be a single, common referencing system for the life cycle of the CTC that supports all the various processes (e.g., information, execution, and control) that necessitate plant and equipment numbers be assigned. This white paper focuses on discovering the full scope of Idaho National Laboratory (INL) processes to which this goal might be applied as well as the factors likely to affect decisions about implementation. Later, a procedure for assigning these numbers will be developed using this white paper as a starting point and that reflects the resolved scope and outcome of associated decisions.

    We report the identification of a novel and defective variant of the gene encoding cytochrome P450 2D6 (CYP2D6). This novel variant is a subtype of CYP2D6*6 that was undetected by a commercially available 5' exonuclease-based assay. Because the novel variant was found in only one of 609 individua......, it represents a rare subtype of CYP2D6*6 that may be restricted to a single family or a subpopulation. A procedure for the identification of the novel CYP2D6*6 variant using restriction enzyme treatment of amplified fragments was developed....

  14. NF-kappa B binding mechanism: a nuclear magnetic resonance and modeling study of a GGG --> CTC mutation.

    We present the solution structure of the nonpalindromic 16 bp DNA 5'd(CTGCTCACTTTCCAGG)3'. 5'd(CCTGGAAAGTGAGCAG)3' containing a mutated kappaB site for which the mutation of a highly conserved GGG tract of the native kappaB HIV-1 site to CTC abolishes NF-kappaB binding. 1H and 31P NMR spectroscopies have been used together with molecular modeling to determine the fine structure of the duplex. NMR data show evidence for a BI-BII equilibrium of the CpA.TpG steps at the 3'-end of the oligomer. Models for the extreme conformations reached by the mutated duplex (denoted 16M) are proposed in agreement with the NMR data. Since the distribution of BII sites is changed in the mutated duplex compared to that of the native duplex (denoted 16N), large differences are induced in the intrinsic structural properties of both duplexes. In particular, in BII structures, 16M shows a kink located at the 3'-end of the duplex, and in contrast, 16N exhibits an intrinsic global curvature toward the major groove. Whereas 16N can reach a conformation very favorable for the interaction with NF-kappaB, 16M cannot mimic such a conformation and, moreover, its deeper and narrower major groove could hinder the DNA-protein interactions.

    2013-01-01

    Highlights: • A theoretical foundation is presented for more efficient Integrated Safeguards (IS). • Probability of undetected nuclear proliferation activities should be maintained low. • For nations under IS, the probability to start proliferation activities is very low. • The fact can decrease the detection probability of IS by dozens of percentage points. • The cost of IS per nation can be cut down by reducing inspection frequencies etc. - Abstract: A theoretical foundation is presented for implementing more efficiently the present International Atomic Energy Agency (IAEA) integrated safeguards (ISs) on the basis of fuzzy evaluation of the probability that the evaluated nation will continue peaceful activities. It is shown that by determining the presence probability of undetected nuclear proliferating activities, nations under IS can be maintained at acceptably low proliferation risk levels even if the detection probability of current IS is decreased by dozens of percentage from the present value. This makes it possible to reduce inspection frequency and the number of collected samples, allowing the IAEA to cut costs per nation. This will contribute to further promotion and application of IS to more nations by the IAEA, and more efficient utilization of IAEA resources from the viewpoint of whole IS framework

There was a similar association between SM use and viral load status, but without achieving statistical significance (OR 1.28, CI 0.89-1.85). Analyses did not demonstrate a dose-response of prescription refill or SM use for change in viral load. PHR use, specifically use of electronic prescription refill, was associated with greater control of HIV. Additional studies are needed to understand the mechanisms by which this may be occurring. ©D Keith McInnes, Stephanie L Shimada, Amanda M Midboe, Kim M Nazi, Shibei Zhao, Justina Wu, Casey M Garvey, Thomas K Houston.

    Background and purpose: In men with adverse pathology at the time of radical prostatectomy (RP), the most appropriate timing to administer radiotherapy (RT) remains a subject for debate. To determine whether salvage radiotherapy (SRT) upon early prostate-specific antigen (PSA) relapse is equivalent to immediate adjuvant radiotherapy (ART) post RP. Material and methods: 130 patients receiving ART and 89 receiving SRT were identified. All had an undetectable PSA after RP. Homogeneous subgroups were built based on the status (±) of lymphatic invasion (LVI) and surgical margins (SM), to allow a comparison of ART and SRT. Biochemical disease-free survival (bDFS) was calculated from the date of surgery and from the end of RT. The multivariate analysis was performed using the Cox Proportional hazard model. Results: In the SM-/LVI- and SM+/LVI- groups, SRT was a significant predictor of a decreased bDFS from the date of surgery, while in the SM+/LVI+ group, there was a trend towards significance. From the end of RT, SRT was also a significant predictor of a decreased bDFS in three patient groups: SM-/LVI-, SM+/LVI- and SM+/LVI+. Gleason score >7 showed to be another factor on multivariate analysis associated with decreased bDFS in the SM-/LVI- group, from the date of surgery and end of RT. Preoperative PSA was a significant predictor in the SM-/LVI- group from the date of RP only. Conclusions: Immediate ART post RP for patients with high risk features in the prostatectomy specimen significantly reduces bDFS after RP compared with early SRT upon PSA relapse.

    Real-time virtual sonography (RVS) is a diagnostic imaging support system, which provides the same cross-sectional multiplanar reconstruction images as ultrasound images on the same monitor screen in real time. The purpose of this study was to evaluate radiofrequency ablation (RFA) assisted by RVS and CT for hepatocellular carcinoma (HCC) undetectable with conventional sonography. Subjects were 20 patients with 20 HCC nodules not detected by conventional sonography but detectable by CT or MRI. All patients had hepatitis C-induced liver cirrhosis; there were 13 males and 7 females aged 55-81 years (mean, 69.3 years). RFA was performed in the CT room, and the tumor was punctured with the assistance of RVS. CT was performed immediately after puncture, and ablation was performed after confirming that the needle had been inserted into the tumor precisely. The mean number of punctures and success rates of the first puncture were evaluated. Treatment effects were evaluated with dynamic CT every 3 months after RFA. RFA was technically feasible and local tumor control was achieved in all patients. The mean number of punctures was 1.1, and the success rate of the first puncture was 90.0%. This method enabled safe ablation without complications. The mean follow-up period was 13.5 month (range, 9-18 months). No local recurrence was observed at the follow-up points. In conclusion, RFA assisted by RVS and CT is a safe and efficacious method of treatment for HCC undetectable by conventional sonography.

    To determine the frequency and clinical significance of previously undetected incidental findings found on computed tomography (CT) simulation images for breast cancer patients. All CT simulation images were first interpreted prospectively by radiation oncologists and then double-checked by diagnostic radiologists. The official reports of CT simulation images for 881 consecutive postoperative breast cancer patients from 2009 to 2010 were retrospectively reviewed. Potentially important incidental findings (PIIFs) were defined as any previously undetected benign or malignancy-related findings requiring further medical follow-up or investigation. For all patients in whom a PIIF was detected, we reviewed the clinical records to determine the clinical significance of the PIIF. If the findings from the additional studies prompted by a PIIF required a change in management, the PIIF was also recorded as a clinically important incidental finding (CIIF). There were a total of 57 (6%) PIIFs. The 57 patients in whom a PIIF was detected were followed for a median of 17 months (range, 3-26). Six cases of CIIFs (0.7% of total) were detected. Of the six CIIFs, three (50%) cases had not been noted by the radiation oncologist until the diagnostic radiologist detected the finding. On multivariate analysis, previous CT examination was an independent predictor for PIIF (p = 0.04). Patients who had not previously received chest CT examinations within 1 year had a statistically significantly higher risk of PIIF than those who had received CT examinations within 6 months (odds ratio, 3.54; 95% confidence interval, 1.32-9.50; p = 0.01). The rate of incidental findings prompting a change in management was low. However, radiation oncologists appear to have some difficulty in detecting incidental findings that require a change in management. Considering cost, it may be reasonable that routine interpretations are given to those who have not received previous chest CT examinations within 1 year

    Intellectual disability is associated with an increased risk of behavioral disturbances and also complicates their treatment. Despite increases in the sophistication of medical detection of early risk for intellectual disability, there is remarkably little data about the detection of intellectual disability in cases referred for psychiatric treatment. In this study, we used a 10-year sample of 23,629 consecutive child and adolescent admissions (ages between 6 and 17) to inpatient psychiatric treatment. Eleven percent (n=2621) of these cases were referred for psychological assessment and were examined with a general measure of intellectual functioning (i.e., WISC-IV). Of these cases, 16% had Full Scale IQs below 70. Of the cases whose therapists then referred them for formal assessment of their adaptive functioning (i.e., ABAS-II) 81% were found to have composite scores below 70 as well. Only one of the cases whose Full Scale IQ was less than 70 had a referral diagnosis of intellectual disability. Cases with previously undetected intellectual disability were found to be significantly more likely to have a diagnosis of a psychotic disorder and less likely to have a diagnosis of mood disorder than cases with IQs over 70. Disruptive behavior disorder diagnoses did not differ as a function of intellectual performance. These data suggest a high rate of undetected intellectual disability in cases with a psychiatric condition serious enough to require hospitalization and this raises the possibility that many such cases may be misdiagnosed, the basis of their problems may be misconceptualized, and they may be receiving treatments that do not take into account their intellectual level.

    The aim of this programme was to find undetected rheumatic heart disease (RHD) in students from selected schools in the Tairawhiti region (eastern part of the North Island) of New Zealand. Portable echocardiography was used to scan students in 5 urban and rural schools in Tairawhiti where the population is predominantly Maori. The age range of students in the urban schools was 10-13 years and in the rural schools 5-17 years. Those with abnormal echocardiograms were referred for a paediatric consultation, with hospital-based echocardiography if required for the clarification of diagnoses and further management. A total of 685 students, representing over 95% of the schools' students, consented to having echocardiographic scanning. After repeat hospital based echocardiography for 11 students, a total of 52 scans were regarded as abnormal. In this population definite (n=4) or probable (n=7) RHD was found in 11 students a prevalence of 1.61% (95%CIs 0.80-2.85). Possible RHD was found in 19 students. Previously undetected confirmed (n=1) or probable (n=7) RHD was found in 8 students a prevalence of 1.17% (95%CIs 0.51-2.29). Congenital heart defects (CHD) were found in 22 students a prevalence of 3.21% (95%CIs 2.02-4.83). Echocardiography was a popular modality and detected a significant burden of previously unknown RHD in this young Maori population who are now receiving penicillin. However, echocardiography detected a greater prevalence of possible RHD for which optimum management is at present uncertain. Echocardiography also detected students with a range of severity of CHD. Screening with echocardiography for RHD would involve a significant use of public health, paediatric and cardiac resources with 7.6% of students and their families requiring clinical consultations and ongoing management of the abnormal echocardiographic results.

  2. Uncovering undetected hypoglycemic events

    Full Text Available Jeff UngerCatalina Research Institute, Chino, CA, USAAbstract: Hypoglycemia is the rate-limiting factor that often prevents patients with diabetes from safely and effectively achieving their glycemic goals. Recent studies have reported that severe hypoglycemia is associated with a significant increase in the adjusted risks of major macrovascular events, major microvascular events, and mortality. Minor hypoglycemic episodes can also have serious implications for patient health, psychological well being, and adherence to treatment regimens. Hypoglycemic events can impact the health economics of the patient, their employer, and third-party payers. Insulin treatment is a key predictor of hypoglycemia, with one large population-based study reporting an overall prevalence of 7.1% (type 1 diabetes mellitus and 7.3% (type 2 diabetes mellitus in insulin-treated patients, compared with 0.8% in patients with type 2 diabetes treated with an oral sulfonylurea. Patients with type 1 diabetes typically experience symptomatic hypoglycemia on average twice weekly and severe hypoglycemia once annually. The progressive loss of islet cell function in patients with type 2 diabetes results in a higher risk of both symptomatic and unrecognized hypoglycemia over time. Patients with diabetes who become hypoglycemic are also more susceptible to developing defective counter-regulation, also known as hypoglycemia awareness autonomic failure, which is life-threatening and must be aggressively addressed. In patients unable to recognize hypoglycemia symptoms, frequent home monitoring or use of continuous glucose sensors are critical. Primary care physicians play a key role in the prevention and management of hypoglycemia in patients with diabetes, particularly in those requiring intensive insulin therapy, yet physicians are often unaware of the multitude of consequences of hypoglycemia or how to deal with them. Careful monitoring, adherence to guidelines, and use of optimal treatment combinations are all important steps toward improving care in patients with diabetes. The most important goals are for primary care physicians to recognize that every patient treated with antihyperglycemic medications is at risk of iatrogenic hypoglycemia and to ask patients about hypoglycemia at every visit.Keywords: hypoglycemia, insulin analogs, type 1 diabetes mellitus, type 2 diabetes mellitus

    To investigate if breast milk interleukin [IL]-7 concentrations are associated with postnatal HIV transmission. A case-control study nested within a cohort of women recruited in Lusaka, Zambia. IL-7 breast milk concentrations were measured in samples from 24 HIV-infected breast-feeding women who transmitted HIV to their child after the neonatal period and from 47 women who did not transmit. Samples were frequency-matched by the time of sample collection (1 week and 1 month postpartum). Logistic regression was used to adjust for possible confounders. For comparison, samples from 18 HIV-uninfected women from the same community were included in the analysis, and plasma IL-7 was determined. Breast milk IL-7 concentrations were significantly higher than plasma IL-7 concentrations in all 3 groups. In contrast to levels among transmitters and HIV-uninfected women, breast milk IL-7 concentrations exhibited a bimodal distribution among nontransmitters. Breast milk IL-7 concentrations undetectable or less than 30 pg/mL were significantly associated with less HIV transmission (odds ratio = 0.13, 95% confidence interval: 0.03 to 0.64). The association remained strong after adjustment for breast milk viral load and sodium, maternal CD4 cell counts, parity, and time of sample collection. Breast milk IL-7 may be necessary for effective HIV transmission.

    Imatinib mesylate (IM) discontinuation is under active investigation in chronic myeloid leukemia-chronic phase (CML-CP) patients with undetectable minimal residual disease (UMRD). However, limited data exist on the long-term outcomes following IM discontinuation in patients treated with frontline IM therapy. We consecutively enrolled patients with CML-CP who discontinued IM after achieving UMRD for ≥12 months between June 2009 and January 2013. Nineteen patients (8 male, 11 female) were included. After IM discontinuation, 14 patients (74%) lost UMRD after a median of 4.0 months. Of the 14 patients with molecular relapses, 12 (86%) relapsed within the first 9 months after IM discontinuation and 2 (14%) relapsed at 20.5 and 22.8 months, respectively. No molecular relapse was observed after 2 years of IM discontinuation. With a median follow-up of 58.1 months (range 23.0-66.5), the estimated UMRD persistence rate at 5 years was 23.7%. IM was readministered in all patients with molecular relapse, and 12 patients (86%) reachieved UMRD at a median of 5.3 months. A high-risk Sokal score, delayed UMRD achievement and short-term IM therapy were significantly associated with molecular relapse. These findings suggest that IM discontinuation in patients who achieved UMRD after frontline IM therapy resulted in favorable long-term outcomes in terms of safety and feasibility. © 2015 S.

    Background Technically, HIV-1 tropism can be evaluated in plasma or peripheral blood mononuclear cells (PBMCs). However, only tropism testing of plasma HIV-1 has been validated as a tool to predict virological response to CCR5 antagonists in clinical trials. The preferable tropism testing strategy in subjects with undetectable HIV-1 viremia, in whom plasma tropism testing is not feasible, remains uncertain. Methods & Results We designed a proof-of-concept study including 30 chronically HIV-1-infected individuals who achieved HIV-1 RNA tropism shifts during viremia suppression suggests that, when available, testing of stored plasma samples is generally safe and informative, provided that HIV-1 suppression is maintained. Tropism testing in PBMCs may not necessarily produce equivalent biological results to plasma, because the structure of viral populations and the diagnostic performance of tropism assays may sometimes vary between compartments. Thereby, proviral DNA tropism testing should be specifically validated in clinical trials before it can be applied to routine clinical decision-making. PMID:23936293

    Full Text Available Despite the identification of circulating tumor cells (CTCs and cell-free DNA (cfDNA as potential blood-based biomarkers capable of providing prognostic and predictive information in cancer, they have not been incorporated into routine clinical practice. This resistance is due in part to technological limitations hampering CTC and cfDNA analysis, as well as a limited understanding of precisely how to interpret emergent biomarkers across various disease stages and tumor types. In recognition of these challenges, a group of researchers and clinicians focused on blood-based biomarker development met at the Canadian Cancer Trials Group (CCTG Spring Meeting in Toronto, Canada on 29 April 2016 for a workshop discussing novel CTC/cfDNA technologies, interpretation of data obtained from CTCs versus cfDNA, challenges regarding disease evolution and heterogeneity, and logistical considerations for incorporation of CTCs/cfDNA into clinical trials, and ultimately into routine clinical use. The objectives of this workshop included discussion of the current barriers to clinical implementation and recent progress made in the field, as well as fueling meaningful collaborations and partnerships between researchers and clinicians. We anticipate that the considerations highlighted at this workshop will lead to advances in both basic and translational research and will ultimately impact patient management strategies and patient outcomes.

    Full Text Available To address the role of translationally active HIV reservoir in chronic inflammation and non-AIDS related disorders, we first need a simple and accurate assay to evaluate viral protein expression in virally suppressed subjects.We optimized an HIV Nef enzyme-linked immunosorbent assay (ELISA and used it to quantify plasma Nef levels as an indicator of the leaky HIV reservoir in an HIV-infected cohort.This study accessed 134 plasma samples from a well-characterized cohort study of HIV-infected and uninfected adults in San Francisco (the SCOPE cohort. We optimized an ELISA for detection of plasma Nef in HIV-negative subjects and HIV-infected non-controllers, and evaluated its utility to quantify plasma Nef levels in a cross-sectional study of ART-suppressed and elite controller HIV-infected subjects.Here, we describe the performance of an optimized HIV Nef ELISA. When we applied this assay to the study cohort we found that plasma Nef levels were correlated with plasma HIV RNA levels in untreated disease. However, we were able to detect Nef in plasma of approximately half of subjects on ART or with elite control, despite the lack of detectable plasma HIV RNA levels using standard assays. Plasma Nef levels were not consistently associated with CD4+ T-cell count, CD8+ T-cell count, self-reported nadir CD4+ T-cell count or the CD4+/CD8+ T-cell ratio in HIV-infected subjects.Since plasma HIV RNA levels are undetectable in virally suppressed subjects, it is reasonable to assume that viral protein expression in leaky reservoir, and not plasma virions, is the source of Nef accumulating in plasma. To examine this further, improvements of the assay sensitivity, by lowering the background through improvements in the quality of Nef antibodies, and detailed characterization of the HIV reservoirs are needed.

    HIV therapy reduces the CSF HIV RNA viral load (VL) and prevents disorders related to HIV encephalitis. However, these brain disorders may persist in some cases. A large population of antiretroviral-treated patients who had a VL > 1.7 log 10 copies/mL in CSF with detectable or undetectable VL in plasma associated with cognitive impairment was studied, in order to characterize discriminatory factors of these two patient populations. Blood and CSF samples were collected at the time of neurological disorders for 227 patients in 22 centres in France and 1 centre in Switzerland. Genotypic HIV resistance tests were performed on CSF. The genotypic susceptibility score was calculated according to the last Agence Nationale de Recherche sur le Sida et les hépatites virales Action Coordonnée 11 (ANRS AC11) genotype interpretation algorithm. Among the 227 studied patients with VL > 1.7 log 10 copies/mL in CSF, 195 had VL detectable in plasma [median (IQR) HIV RNA was 3.7 (2.7-4.7) log 10 copies/mL] and 32 had discordant VL in plasma (VL plasma compared with patients with plasma VL > 1.7 log 10 copies/mL. Resistance to antiretrovirals was observed in CSF for the two groups of patients. Fourteen percent of this population of patients with cognitive impairment and detectable VL in CSF had well controlled VL in plasma. Thus, it is important to explore CSF HIV (VL and genotype) even if the HIV VL is controlled in plasma because HIV resistance may be observed. © The Author 2017.

    The present study is to determine the prevalence and implication of coeliac disease (CD) among adult Saudis and compared to those with diagnosed irritable bowel syndrome. This prospective study was conducted among 980 adults. Out of that, 482 subjects (staff and students of Riyadh Health Science College) were designated as control cohorts for undetected coeliac disease. Furthermore, another contingent of 498 subjects diagnosed with irritable bowel syndrome (IBS) at Prince Salman Hospital and Al-Iman General Hospital also constituted a segment of the overall initial 1020 subjects. Both cases and control were tested for serological markers of coeliac disease (tissues transglutaminase (tTGAs) and endomysial autoantibody (EMAs) and were confirmed by histopathology test. All the positive for cases of coeliac disease were screened for iron deficiency anaemia, Vitamin D deficiency, and osteoporosis and weight assessment. The percentage of coeliac disease in control subjects and patients diagnosed with irritable bowel syndrome (IBS) were found to be 1.9% and 9.6% respectively, about 38% of the total coeliac disease patients are among females of middle age (20-39-years) and 16% of the males in the same age range. Whereas, 20% and 25% of all coeliac disease cases with ages of 40-59 were remarked as females and males respectively. The identical nature and overlap of symptoms of the two conditions could possibly result in misdiagnosis of coeliac diseases or over-diagnosis of irritable bowel syndrome. The findings of the study might also give considerable implications of the disease in the nutritional level which is noticeable.

    The purpose of this study was to evaluate the feasibility of non-real-time CT-guided percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC, 37 lesions) untreatable by ultrasonography-guided (US)-PEIT. The HCC lesion was localized on the lipiodol CT image with a graduated grid system. We advanced a 21 G or 22 G needle in a stepwise fashion with intermittent localization scans using a tandem method to position the tip of the needle in the lesion. Ethanol containing contrast medium was injected with monitoring scans obtained after incremental volumes of injection, until perfusion of the lesion was judged to be complete. A total of 44 CT-PEIT procedures were performed. The average number of needle passes from the skin to the liver in each CT-PEIT procedure was 2.3, the average amount of ethanol injected was 14.4 ml, and the average time required was 49.3 minutes. Complete perfusion of the lesion by ethanol on monitoring CT images was achieved in all lesions with only a single or double CT-PEIT procedure without severe complication. Local recurrence was detected only in 5 lesions. At present, it is more time-consuming to perform CT-PEIT than US-PEIT because conventional CT guidance is not real-time imaging. However, it is expected that this limitation of CT-PEIT will be overcome in the near future with the introduction of CT fluoroscopy. In conclusion, CT-PEIT should prove to be a feasible, acceptable treatment for challenging cases of HCC undetectable by US. (author)

    Alcohol intoxicated adolescents (AIA) in emergency department are an important target group for prevention and valid information on their familial risk and protective factors (RPF) is crucial for implementing customized family-based counseling in hospitals. We therefore, examined the psychometric characteristics of scales which assess familial RPF. We used seven family scales from the Communities That Care Youth Survey Instrument (CTC-F7); four assess risk factors: family conflicts, poor family management, parental attitudes favorable towards drug use/antisocial behavior; three assess protective factors: family attachment, opportunities and rewards for prosocial involvement. To assess physical and emotional abuse and emotional neglect, we created a new scale composed of six items from the Childhood Trauma Questionnaire (CTQ-6). We tested these eight scales on 342 AIA aged 13-17. Based on the classical test theory we calculated descriptive item and scale statistics and internal consistency. We assessed construct validity by confirmatory factor analysis with Maximum Likelihood (ML) estimation in a sample with imputed missing values (EM-Algorithm). To check robustness, we repeated the analyses with complete cases, with multiple imputed data, and with methods suitable for categorical data. We used SPSS 21, AMOS 21 and R (randomForrest and lavaan package). Three of seven CTC-F scales showed poor psychometric properties in the descriptive analysis. A ML-confirmatory model with five latent factors fitted the remaining CTC-F scales best (CTC-F5). The latent structure of the CTQ-6 is characterized by three first-order factors (physical abuse, emotional abuse, emotional neglect) and one second-order factor. The global goodness-of-fit indices for the CTC-F5 and the CTQ-6 demonstrated acceptable fit (for both models: TLI and CFI>0.97, RMSEA0.7). The final CTC-F5 and the newly developed CTQ-6 demonstrate acceptable to good psychometric properties for the AIA sample. The CTC-F5

    Context. Showing 1.4 GHz flux densities in the range of a few to a few tens of mJy, infrared-faint radio sources (IFRS) are a type of galaxy characterised by faint or absent near-infrared counterparts and consequently extreme radio-to-infrared flux density ratios up to several thousand. Recent studies showed that IFRS are radio-loud active galactic nuclei (AGNs) at redshifts ≳2, potentially linked to high-redshift radio galaxies (HzRGs). Aims: This work explores the far-infrared emission of IFRS, providing crucial information on the star forming and AGN activity of IFRS. Furthermore, the data enable examining the putative relationship between IFRS and HzRGs and testing whether IFRS are more distant or fainter siblings of these massive galaxies. Methods: A sample of six IFRS was observed with the Herschel Space Observatory between 100 μm and 500 μm. Using these results, we constrained the nature of IFRS by modelling their broad-band spectral energy distribution (SED). Furthermore, we set an upper limit on their infrared SED and decomposed their emission into contributions from an AGN and from star forming activity. Results: All six observed IFRS were undetected in all five Herschel far-infrared channels (stacking limits: σ = 0.74 mJy at 100 μm, σ = 3.45 mJy at 500 μm). Based on our SED modelling, we ruled out the following objects to explain the photometric characteristics of IFRS: (a) known radio-loud quasars and compact steep-spectrum sources at any redshift; (b) starburst galaxies with and without an AGN and Seyfert galaxies at any redshift, even if the templates were modified; and (c) known HzRGs at z ≲ 10.5. We find that the IFRS analysed in this work can only be explained by objects that fulfil the selection criteria of HzRGs. More precisely, IFRS could be (a) known HzRGs at very high redshifts (z ≳ 10.5); (b) low-luminosity siblings of HzRGs with additional dust obscuration at lower redshifts; (c) scaled or unscaled versions of Cygnus A at any

  14. HIV-1 tropism testing in subjects achieving undetectable HIV-1 RNA: diagnostic accuracy, viral evolution and compartmentalization.

    Directory of Open Access Journals (Sweden)

    Christian Pou

    Full Text Available BACKGROUND: Technically, HIV-1 tropism can be evaluated in plasma or peripheral blood mononuclear cells (PBMCs. However, only tropism testing of plasma HIV-1 has been validated as a tool to predict virological response to CCR5 antagonists in clinical trials. The preferable tropism testing strategy in subjects with undetectable HIV-1 viremia, in whom plasma tropism testing is not feasible, remains uncertain. METHODS & RESULTS: We designed a proof-of-concept study including 30 chronically HIV-1-infected individuals who achieved HIV-1 RNA <50 copies/mL during at least 2 years after first-line ART initiation. First, we determined the diagnostic accuracy of 454 and population sequencing of gp120 V3-loops in plasma and PBMCs, as well as of MT-2 assays before ART initiation. The Enhanced Sensitivity Trofile Assay (ESTA was used as the technical reference standard. 454 sequencing of plasma viruses provided the highest agreement with ESTA. The accuracy of 454 sequencing decreased in PBMCs due to reduced specificity. Population sequencing in plasma and PBMCs was slightly less accurate than plasma 454 sequencing, being less sensitive but more specific. MT-2 assays had low sensitivity but 100% specificity. Then, we used optimized 454 sequence data to investigate viral evolution in PBMCs during viremia suppression and only found evolution of R5 viruses in one subject. No de novo CXCR4-using HIV-1 production was observed over time. Finally, Slatkin-Maddison tests suggested that plasma and cell-associated V3 forms were sometimes compartmentalized. CONCLUSIONS: The absence of tropism shifts during viremia suppression suggests that, when available, testing of stored plasma samples is generally safe and informative, provided that HIV-1 suppression is maintained. Tropism testing in PBMCs may not necessarily produce equivalent biological results to plasma, because the structure of viral populations and the diagnostic performance of tropism assays may sometimes vary

    Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on anecdotal evidence that the captive subjects appear more relaxed with the trained event. Blood markers of physiological stress responses were evaluated in 4 captive grizzly bears (Ursus arctos horribilis) who were clicker-trained for blood collection versus 4 bears who were chemically immobilized for blood collection. Serum cortisol and immunoglobulin A (IgA) and plasma β-endorphin were measured as indicators of responses to stress. Plasma β-endorphin was not different between the groups. Serum IgA was undetectable in all bears. Serum cortisol was undetectable in all trained bears, whereas chemically immobilized bears had marked cortisol elevations (p bears with extensive recent immobilization experience. These findings support the use of positive reinforcement training for routine health procedures to minimize anxiety.

    To compare the clinical course of patients with AIDS-related Kaposi's sarcoma (KS) with CD4 counts >300 cells/mm(3) and undetectable HIV viral loads (VLs) to patients with AIDS-KS with lesser CD4 counts and detectable HIV VLs. We retrospectively analyzed a cohort of 91 patients with AIDS-KS in a multispeciality clinic. We used chi(2) and Student t tests to analyze intragroup differences; survival was determined by Kaplan-Meier analysis. Twenty (22%) of the 91 patients had newly diagnosed, persistent or progressive KS despite CD4 counts >300 cells/mm(3) and undetectable HIV VLs. Age, gender, ethnicity, mode and duration of HIV acquisition, type of antiretroviral therapy (ART), and KS therapy did not differ significantly (P counts active antiretroviral (HAART) era, a substantial proportion of patients with KS had undetectable HIV VLs and CD4 counts greater than the level typically associated with opportunistic diseases. They required systemic therapy to control their KS but were significantly less likely to die and demonstrated a trend toward better 15-year survival than patients having KS with lesser CD4 counts and detectable HIV VLs.

    Prostate cancer recurrences are usually first detected by increased levels of prostate specific antigen (PSA), and systemic therapy is often initiated if distant metastasis is confirmed. However, low or nearly undetectable levels of PSA in the modern era of ultrasensitive PSA assay may be difficult to interpret in patients with a history of prostate cancer. Deciding whether to initiate additional systemic therapy in limited indolent metastatic disease while balancing the quality of life of the patient and ensuring the oncologic control of the disease may be challenging. In the present study, the case of a biopsy-confirmed solitary spine recurrence of prostate cancer with nearly undetectable but persistent levels of PSA (0.05 ng/ml) is reported. Treatment of the recurrence with local ablative radiotherapy improved the pain experienced by the patient, and reduced his levels of PSA to undetectable limits (<0.05 ng/ml). Repeated imaging analysis, PSA assay and clinical assessment demonstrated durable control of the disease without the requirement for additional systemic treatments. The present case highlighted the importance of initiating appropriate work-up according to the clinical scenario. Local treatment for solitary or oligometastatic recurrence of prostate cancer may enhance the effectiveness of current therapeutic strategies and benefit certain patients.

    Full Text Available OBJECTIVE: The objective of this study was to determine the risk for the development of high depressive symptoms in study participants with diagnosed and previously undetected diabetes mellitus compared to those without diabetes in a prospective population-based cohort study in Germany. METHODS: We estimated the 5-year cumulative incidence of high depressive symptoms in participants without high depressive symptoms at baseline (n = 3,633, 51.4% men, mean age (SD 59.1 (7.6 years, 7.0% diagnosed diabetes, 5.3% previously undetected diabetes from the population-based Heinz Nixdorf Recall study. Diabetes was assessed by self-report, medication, and blood glucose. High depressive symptoms were assessed using CES-D. We calculated odds ratios and their corresponding 95% confidence interval, using multiple logistic regression analyses. RESULT: Cumulative 5-year incidences (95% CI of high depressive symptoms in participants with diagnosed, undetected, and without diabetes were 7.1 (4.2-10.9, 4.1 (1.8-8.0, and 6.5 (5.6-7.4, respectively. The age-sex-adjusted OR for developing high depressive symptoms was 1.22 (0.74-2.03 in participants with diagnosed compared to those without diabetes, and 1.00 (0.59-1.68 after adjustment for BMI, physical activity, education, stroke, and myocardial infarction. The age-sex adjusted OR for developing high depressive symptoms in participants with previously undetected diabetes compared to those without diabetes was 0.72; 0.35-1.48; and fully adjusted 0.62; 0.30-1.30. CONCLUSION: We found no significant associations, maybe due to low power. However, our results are in line with a recent meta-analysis suggesting that risk of developing high depressive symptoms in patients with diagnosed diabetes may be moderately higher than in those without diabetes, and that comorbidity may explain in part this association. In participants with previously undetected diabetes, this first longitudinal study indicates that the risk is not

    Epstein-Barr virus (EBV) is closely associated with nasopharyngeal carcinoma (NPC). Serum IgA antibodies against early antigen (EA-IgA) and viral capsid antigen (VCA-IgA) are the most commonly used to screen for NPC in endemic areas. However, the prognostic value of serum EA-IgA and VCA-IgA in patients with NPC is less clear. We hypothesize that serum EA-IgA and VCA-IgA levels have prognostic impact for survival outcomes in NPC patients with undetectable pretreatment EBV (pEBV) DNA. In this series, 334 patients with non-metastatic NPC and undetectable pEBV DNA were included. Serum EA-IgA and VCA-IgA were determined by ELISA. After analysis, serum EA-IgA and VCA-IgA loads correlated positively with T, N, and overall stage (all P 1:120 had significantly inferior 5-year progression-free survival (80.4% vs 89.6%, P = 0.025), distant metastasis-free survival (88.4% vs 94.8%, P = 0.050), and locoregional relapse-free survival (88.4% vs 95.6%, P = 0.023; log-rank test). Multivariable analyses revealed that N stage was the only independent prognostic factor (all P < 0.05), but the VCA-IgA became insignificant. Further analyses revealed that serum VCA-IgA was not an independent prognostic factor in early N (N0-1) or advanced N (N2-3) stage NPC. In summary, although both EA-IgA and VCA-IgA correlate strongly with TNM stage, our analyses do not suggest that these antibodies are prognostic biomarkers in patients with NPC and undetectable pEBV DNA. © 2017 The Authors.

    Students with cognitive impairment are at increased risk of suffering from visual impairment due to refractive errors and ocular disease, which can adversely influence learning and daily activities. The purpose of this study was to evaluate the ocular and visual status among students at the special education school in Hualien. All students at the National Hualien Special Education School were evaluated. Full eye examinations were conducted by a skilled ophthalmologist. The students' medical records and disability types were reviewed. A total of 241 students, aged 7-18 years, were examined. Visual acuity could be assessed in 138 students. A total of 169/477 (35.4%) eyes were found to suffer from refractive errors, including 20 eyes with high myopia (≤-6.0 D) and 16 eyes with moderate hypermetropia (+3.0 D to +5.0 D). A total of 84/241 (34.8%) students needed spectacles to correct their vision, thus improving their daily activities and learning process, but only 15/241 (6.2%) students were wearing suitable corrective spectacles. A total of 55/241 students (22.8%) had ocular disorders, which influenced their visual function. The multiple disability group had a statistically significant higher prevalence of ocular disorders (32.9%) than the simple intellectual disability group (19.6%). Students with cognitive impairment in eastern Taiwan have a high risk of visual impairment due to refractive errors and ocular disorders. Importantly, many students have unrecognized correctable refractive errors. Regular ophthalmic examination should be administered to address this issue and prevent further disability in this already handicapped group. Copyright © 2016. Published by Elsevier B.V.

    HIV infection treatment strategies have historically defined effectiveness through measuring patient plasma HIV RNA. While combined antiretroviral therapy (cART) can reduce plasma viral load (pVL) to undetectable levels, the degree that HIV is eliminated from other anatomical sites remains unclear. We investigated the HIV DNA levels in 229 varied autopsy tissues from 20 HIV-positive (HIV(+)) cART-treated study participants with low or undetectable plasma VL and cerebrospinal fluid (CSF) VL prior to death who were enrolled in the National Neurological AIDS Bank (NNAB) longitudinal study and autopsy cohort. Extensive medical histories were obtained for each participant. Autopsy specimens, including at least six brain and nonbrain tissues per participant, were reviewed by study pathologists. HIV DNA, measured in tissues by quantitative and droplet digital PCR, was identified in 48/87 brain tissues and 82/142 nonbrain tissues at levels >200 HIV copies/million cell equivalents. No participant was found to be completely free of tissue HIV. Parallel sequencing studies from some tissues recovered intact HIV DNA and RNA. Abnormal histological findings were identified in all participants, especially in brain, spleen, lung, lymph node, liver, aorta, and kidney. All brain tissues demonstrated some degree of pathology. Ninety-five percent of participants had some degree of atherosclerosis, and 75% of participants died with cancer. This study assists in characterizing the anatomical locations of HIV, in particular, macrophage-rich tissues, such as the central nervous system (CNS) and testis. Additional studies are needed to determine if the HIV recovered from tissues promotes the pathogenesis of inflammatory diseases, such as HIV-associated neurocognitive disorders, cancer, and atherosclerosis. It is well-known that combined antiretroviral therapy (cART) can reduce plasma HIV to undetectable levels; however, cART cannot completely clear HIV infection. An ongoing question is

    Interference of antithyroglobulin antibodies (TgAb) with serum thyroglobulin (Tg) can occur even at detectable TgAb concentrations below the reference limit (borderline TgAb). Thus, borderline TgAb is considered as TgAb positivity in patients with thyroid cancer. This prospective study evaluated patients with papillary thyroid carcinoma with undetectable Tg and normal neck ultrasonography (US) after total thyroidectomy and ablation with 131 I, and compared tumor persistence/recurrence and long-term Tg and TgAb behavior in those with borderline versus undetectable TgAb. A total of 576 patients were evaluated, divided into two groups: group A with undetectable TgAb (n = 420), and group B with borderline TgAb (n = 156). Groups A and B were similar in terms of patient and tumor characteristics. The time of follow-up ranged from 24 to 120 months. During follow-up, 11 (2.6%) patients in group A and 5 (3.2%) in group B developed a recurrence (p = 0.77). In group A, recurrences occurred in 9/390 patients who continued to have undetectable TgAb and in 1/9 patients who progressed to borderline TgAb. In group B, recurrences were detected in 1/84 patients who progressed to have undetectable TgAb, in 1/45 who still had borderline TgAb, and in 3/12 who developed elevated TgAb. In the presence of Tg levels borderline TgAb, and in 3/12 with elevated TgAb. The results of post-therapy whole-body scanning (RxWBS) of 216 patients with Tg ≤0.2 ng/mL and normal US at the time of ablation were also analyzed. In low-risk patients, none of the 40 patients with borderline TgAb and none of the 94 with undetectable TgAb exhibited ectopic uptake on RxWBS. In intermediate-risk patients, lymph node metastases were detected by RxWBS in 1/25 (4%) with borderline TgAb and in 2/57 (3.5%) with undetectable TgAb. The results suggest that among low- or intermediate-risk patients with undetectable Tg and normal US after thyroidectomy, those with borderline TgAb are at no greater risk of

  5. The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20%

    The slugs of Britain and Ireland form a well-studied fauna of economic importance. They include many widespread European species that are introduced elsewhere (at least half of the 36 currently recorded British species are established in North America, for example). To test the contention that the British and Irish fauna consists of 36 species, and to verify the identity of each, a species delimitation study was conducted based on a geographically wide survey. Comparisons between mitochondrial DNA (COI, 16S), nuclear DNA (ITS-1) and morphology were investigated with reference to interspecific hybridisation. Species delimitation of the fauna produced a primary species hypothesis of 47 putative species. This was refined to a secondary species hypothesis of 44 species by integration with morphological and other data. Thirty six of these correspond to the known fauna (two species in Arion subgenus Carinarion were scarcely distinct and Arion (Mesarion) subfuscus consisted of two near-cryptic species). However, by the same criteria a further eight previously undetected species (22% of the fauna) are established in Britain and/or Ireland. Although overlooked, none are strictly morphologically cryptic, and some appear previously undescribed. Most of the additional species are probably accidentally introduced, and several are already widespread in Britain and Ireland (and thus perhaps elsewhere). At least three may be plant pests. Some evidence was found for interspecific hybridisation among the large Arion species (although not involving A. flagellus) and more unexpectedly in species pairs in Deroceras (Agriolimacidae) and Limacus (Limacidae). In the latter groups, introgression appears to have occurred in one direction only, with recently-invading lineages becoming common at the expense of long-established or native ones. The results show how even a well-studied, macroscopic fauna can be vulnerable to cryptic and undetected invasions and changes. PMID:24740519

    Our objective was to investigate the effect of various reimmunization schemes for hepatitis B in adults with low or undetectable anti-HBs titers. Over 2 years, 10 μg of Saccharomyces cerevisiae-recombinant hepatitis B virus (HBV) vaccine (synthesized in China) was used in at least one standardized scheme to immunize 2,310 healthy male and nonpregnant female adults. Of these, 240 subjects tested negative for hepatitis B markers. These 240 subjects were equally divided into 4 groups. The first group, designated Engerix-40, was revaccinated with 40 μg Engerix-B; the second, Engerix-20, was revaccinated with 20 μg Engerix-B; the third, Chinese-20, was revaccinated with 20 μg Chinese-made yeast-recombinant vaccine; and the last group, Chinese-10, was revaccinated with 10 μg Chinese-made yeast-recombinant vaccine. Blood samples were collected before and 1, 2, 8, and 12 months after the first injection. The anti-HBs-positive conversion rates of the Engerix-40, Engerix-20, and Chinese-20 groups were higher than that of the Chinese-10 group (P anti-HBs conversion rate increased in all groups, but values were significantly different from those for the other groups only in the Chinese-10 group (P anti-HBs geometric mean titers (GMTs) of the Engerix-40, Engerix-20, and Chinese-20 groups were higher than in the Chinese-10 group (P anti-HBs titers in subjects with low or undetectable titers after HBV vaccination.

    Full Text Available A strain of Bacillus pumilus was isolated and identified from water samples collected from a small affluent of the Amazon River. Type II restriction endonuclease activity was detected in these bacteria. The enzyme was purified and the molecular weight of the native protein estimated by gel filtration and SDS-PAGE. The optimum pH, temperature and salt requirements were determined. Quality control assays showed the complete absence of "nonspecific nucleases." Restriction cleavage analysis and DNA sequencing of restriction fragments allowed the unequivocal demonstration of 5´GAG¯CTC3´ as the recognition sequence. This enzyme was named BpuAmI and is apparently a neoschizomer of the prototype restriction endonuclease SacI. This is the first report of an isoschizomer and/or neoschizomer of the prototype SacI identified in the genus Bacillus.Uma linhagem de Bacillus pumilus foi isolada e identificada de amostras de águas coletadas em um pequeno Igarapé do Rio Amazonas. Foi detectada atividade de restrição do tipo II nesta bactéria. A enzima foi purificada e o peso molecular da proteína nativa foi estimado por gel filtração e por eletroforese em gel de poliacrilamida. Foram determinados, o pH e temperatura ótimos e as necessidades de sais. Os ensaios do controle de qualidade mostraram uma ausência completa de "nucleases não específicas". As analises das clivagens e o seqüenciamento do DNA dos fragmentos de restrição permitiram uma demonstração inequívoca de que 5´GAG¯CTC 3´ é a seqüência de reconhecimento da enzima. Esta enzima foi denominada de BpuAmI e aparentemente é um neoesquisômero da enzima protótipo SacI. Este é o primeiro relato de um isoesquisômero e/ou neoesquisômero da enzima protótipo SacI identificada no gênero Bacillus.

    To assess the frequency and amount of residual cement after attachment of monolithic zirconia crowns to standard and individualized ceramic abutments. Twenty patients (mean age 58.9 years at inclusion in the study; 30% male) were randomized to receive either a standard or an individualized abutment on a bone-level implant. Monolithic zirconia single crowns were attached to abutments by use of permanent glass-ionomer cement. Crowns were fabricated with an occlusal hole to enable unscrewing of the abutment-crown complex. Immediately after cementation, superstructures were removed and both the peri-implant soft tissue and the abutment-crown complex were photographed in a standardized manner, to detect residual cement. Photographs were analyzed using Corel Photo Paint X7, and residual cement-to-total abutment and residual cement-to-peri-implant soft tissue area ratios were calculated. Residual cement was observed for 9 of 10 (90%) individualized abutments, compared with 4 of 10 (40%) standard abutments (OR = 13.5, P = 0.049). Twenty-seven of 40 (68%) individualized abutment surfaces were affected, compared with 12 of 40 (30%) standard abutment surfaces. The probability of observing residual cement was approximately five times higher for the surfaces of individualized abutments than for those of standard abutments (P = 0.005). The mean amount of sulcus surface covered by cement was 1.17% (SD 2.85) for the individualized abutments and 3.78% (SD 7.40) for the standard abutments. The position of the margin significantly affected the amount of residual cement. Both individualized and standard all-ceramic abutments result in small amounts of subgingival residual cement on abutment and sulcus surfaces. However, use of individualized abutments does not guarantee complete avoidance of undetected cement rests. Undetected residual cement might be avoided by use of all-ceramic abutments with visible abutment shoulders. © 2015 John Wiley & Sons A/S. Published by John Wiley

    Atazanavir seems to be a protease inhibitor (PI) with a more favourable metabolic profile. Information regarding the potential benefit of replacing lopinavir/ritonavir by atazanavir in HIV-infected patients with prolonged viral suppression is scarce. If proved, this strategy could be particularly attractive for the subset of patients with greater cardiovascular risk. SLOAT was a prospective, open, comparative trial in which patients receiving lopinavir/ritonavir-based regimens and having undetectable plasma HIV-RNA for longer than 24 weeks were randomized to continue on the same therapy or switch to atazanavir. Outcomes in viral rebound, CD4 counts, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides and glucose were compared in both groups of patients at 48 weeks of follow-up. A total of 189 patients were recruited and took at least the first dose of the assigned treatment arm. Overall, 102 switched to atazanavir (49 on 400 mg once daily, and 53 on 300 mg plus 100 mg of ritonavir once daily due to concomitant tenofovir use) and 87 continued on lopinavir/ritonavir. All patients received the PI along with two nucleoside analogues. Virological failure occurred in 12 patients switched to atazanavir and 9 continuing on lopinavir/ritonavir. A reduction (P replacement of lopinavir/ritonavir by atazanavir provides an overall significant reduction in total cholesterol and triglycerides, without increased risk of virological failure.

    Hypometabolism may play an important role in the pathogenesis of ageing and ageing-related diseases. The nematode Caenorhabditis elegans offers the opportunity to study "living mitochondria" in a small (~1 mm) animal replete with a highly stereotypical, yet complex, anatomy and physiology. Basal oxygen consumption rate is often employed as a proxy for energy metabolism in this context. This parameter is traditionally measured using single-chamber Clark electrodes without the addition of metabolic modulators. Recently, multi-well oxygen electrodes, facilitating addition of metabolic modulators and hence study of respiratory control during different mitochondrial respiration states, have been developed. However, only limited official protocols exist for C. elegans, and key limitations of these techniques are therefore unclear. Following modification and testing of some of the existing protocols, we used these methods to explore mitochondrial bioenergetics in live nematodes of an electron transfer chain Complex II mutant strain, mev-1, and identified a previously undetected metabolic defect. We find that mev-1 mutants cannot respond adequately to increased energy demands, suggesting that oxidative phosphorylation is more severely impaired in these animals than has previously been appreciated.

    Full Text Available Increased access to highly active antiretroviral therapy (HAART by human immunodeficiency virus postive (HIV+ individuals has become a reality worldwide. In Brazil, HAART currently reaches over half of HIV-infected subjects. In the context of a remarkable HIV-1 genetic variability, highly related variants, called quasispecies, are generated. HIV quasispecies generated during infection can influence virus persistence and pathogenicity, representing a challenge to treatment. However, the clinical relevance of minority quasispecies is still uncertain. In this study, we have determined the archived proviral sequences, viral subtype and drug resistance mutations from a cohort of HIV+ patients with undetectable viral load undergoing HAART as first-line therapy using next-generation sequencing for near full-length virus genome (NFLG assembly. HIV-1 consensus sequences representing NFLG were obtained for eleven patients, while for another twelve varying genome coverage rates were obtained. Phylogenetic analysis showed the predominance of subtype B (83%; 19/23. Considering the minority variants, 18 patients carried archived virus harboring at least one mutation conferring antiretroviral resistance; for six patients, the mutations correlated with the current ARVs used. These data highlight the importance of monitoring HIV minority drug resistant variants and their clinical impact, to guide future regimen switches and improve HIV treatment success.

    Control of highly pathogenic avian influenza (HPAI) outbreaks in poultry has traditionally involved the establishment of disease containment zones, where poultry products are only permitted to move from within a zone under permit. Nonpasteurized liquid egg (NPLE) is one such commodity for which movements may be permitted, considering inactivation of HPAI virus via pasteurization. Active surveillance testing at the flock level, using targeted matrix gene real-time reversed transcriptase-polymerase chain reaction testing (RRT-PCR) has been incorporated into HPAI emergency response plans as the primary on-farm diagnostic test procedure to detect HPAI in poultry and is considered to be a key risk mitigation measure. To inform decisions regarding the potential movement of NPLE to a pasteurization facility, average HPAI virus concentrations in NPLE produced from a HPAI virus infected, but undetected, commercial table-egg-layer flock were estimated for three HPAI virus strains using quantitative simulation models. Pasteurization under newly proposed international design standards (5 log10 reduction) is predicted to inactivate HPAI virus in NPLE to a very low concentration of less than 1 embryo infectious dose (EID)50 /mL, considering the predicted virus titers in NPLE from a table-egg flock under active surveillance. Dilution of HPAI virus from contaminated eggs in eggs from the same flock, and in a 40,000 lb tanker-truck load of NPLE containing eggs from disease-free flocks was also considered. Risk assessment can be useful in the evaluation of commodity-specific risk mitigation measures to facilitate safe trade in animal products from countries experiencing outbreaks of highly transmissible animal diseases. © 2015 Society for Risk Analysis.

    Muscarinic receptors in the brain play an important role in cognitive function, especially memory, and there is growing awareness that specific antimuscarinic drugs for overactive bladder (OAB) may have adverse central nervous system (CNS) effects. Selection of an antimuscarinic OAB drug with reduced potential for CNS effects could be especially beneficial in the elderly people, in whom even the modest cognitive impairment may negatively affect independence. The purpose of the study is to determine if trospium chloride is assay detectable in the CNS of older adults with OAB and to assess whether deterioration of memory occurs in these individuals. Twelve cognitively intact older adults (>or=65-75 years old) with OAB were given extended-release trospium chloride 60 mg once daily over a 10-day period to achieve plasma steady-state levels. Standardised memory testing (Hopkins Verbal Learning Test-Revised and Brief Visuospatial Memory Test-Revised) was performed predose and postdose. Cerebrospinal spinal fluid (CSF) and plasma samples were drawn on day 10 and assayed for trospium chloride. Predose (day 0) and postdose (day 10) results on the memory tests were compared using a reliable change index to assess a meaningful change in learning or memory. Trospium chloride levels in all the CSF samples (n = 72) of all participants were assay undetectable (memory testing revealed no significant net drug effect on learning or recall. This is the first study to investigate for the presence of an OAB antimuscarinic in the human brain, performed by assaying for concentrations of trospium chloride and correlating with simultaneous clinical cognitive safety measures. The results of both pharmacological and neuropsychological testing support the hypothesis of a lack of detectable CNS penetration for the quaternary amine trospium chloride.

    The aim of this study was to assess the frequency of cement residues after cementation of CAD/CAM monolithic zirconia crowns on customized CAD/CAM titanium abutments. Sixty premolars and molars were restored on Astra Tech Osseospeed TX ™ implants using single monolithic zirconia crowns fixed on two types of custom-made abutments: Atlantis ™ titanium or Atlantis ™ Gold Hue. Occlusal openings providing access to the abutment screws were designed for retrievability of the crown/abutment connection. After fixation with glass ionomer cement, the crown/abutment units were unscrewed to evaluate the presence of residual cement. Dichotomous assessment of the presence or absence of cement at the crown/abutment unit and peri-implant tissues was performed. Clinically undetected cement excess was visible on 44 of 60 restorations (73.3%). There was no interdependency between residual cement presence and implant location or diameter. However, a dependency between the presence of residual cement and the aspect of the abutment/crown connection could be noted. The majority of the residues were observed on the distal (17.9%) and mesial (15%) aspects. While on the palatal/lingual aspect, the cement was visible in 8.8%; only 3.4% of all surfaces displayed cement residues. Within the limitations of the study, it can be concluded that the use of customized CAD/CAM abutments do not guarantee avoidance of subgingival cement residues after crown cementation. © 2016 John Wiley & Sons A/S.

  16. Self-reported adherence and pharmacy refill adherence are both predictive for an undetectable viral load among HIV-infected migrants receiving cART.

    Full Text Available HIV-infected migrants were shown to have poorer treatment outcomes than Dutch HIV-infected patients, often due to worse treatment adherence. Self-reported adherence would be an easy way to monitor adherence, but its validity relative to pharmacy refill adherence has not been extensively evaluated in migrants. All HIV-infected migrants older than 18 years and in care at the two Rotterdam HIV-treatment centers were eligible. Refill data with leftover medication (PRL (residual pill count were obtained from their pharmacies up to 15 months prior to inclusion. Self-reported adherence to combination Antiretroviral Therapy was assessed by four questions about adherence at inclusion. Additionally, risk factors for pharmacy refill non-adherence were examined. In total, 299 HIV-infected migrants were included. Viral load (VL was detectable in 11% of the patients. Specificity of PRL was 53% for patients with an adherence of 100% and decreased with lower cut-off values. Sensitivity and negative predictive value (NPV were 68% and 15% and increased with lower cut-off values. Positive predictive value (PPV was around 93% for all cut-off values. Using the self-reported questions, 139 patients (47% reported to be adherent. Sensitivity was 49% and specificity was 72%. PPV and NPV were 95% and 13%. No risk factors for pharmacy refill non-adherence were found in multivariable analyses. Both PRL and self-reported adherence, can predict undetectable VL in HIV-infected migrants. PPV and NPV are similar for both methods. This study shows that using four self-reported items is sufficient to predict adherence which is crucial for optimal clinical outcome in HIV-infected migrants.

    Beyond the detection of resistant HIV strains found in plasma samples, archival HIV-DNA in peripheral blood mononuclear cells (PBMCs) might represent a reservoir of additional resistance. To characterize the HIV-1 resistance in PBMCs from patients with suppressed or low-level viremia (50-1000 copies/mL) and evaluate its added value compared to the resistance detected in previous plasma genotypic resistance tests (GRTs). HIV-1 infected patients selected for treatment change despite low/undetectable viremia were tested. Number and type of primary resistance mutations (PRMs) detected in PBMCs were compared to those detected in previous plasma GRTs. Logistic regression assessed factors associated with presence of at least one PRM in PBMCs. 468 patients with a PBMC GRT were analyzed; 149 of them had at least 2 plasma GRTs performed before PBMC genotyping. 42.3% of patients showed at least one PRM in PBMCs. The highest proportion of PRMs in PBMCs was observed for NRTI class (30.6%), followed by NNRTI (22.2%), PI (14.1%) and INI (4.9%). In 20.1% of patients, PRMs were detected only in PBMCs and not in any of the plasma GRT previously performed. By using multivariable analysis, a higher number of previous regimens, injecting drug-use route and a lower nadir CD4 were associated with significantly higher risk of detecting PRMs in PBMCs. Our findings support the usage of PBMC GRT in addition to the current recommended plasma RNA test, especially when therapeutic and/or resistance information is not available.

    Andréia M Menezes

    Full Text Available BACKGROUND: To determine the prevalence and associated factors with chronic kidney disease (CKD in a cohort of HIV-positive individuals with undetectable viral load on HAART. METHODS: From March, 2009 to September 2009, 213 individuals between 18-70 years, period on HAART ≥12 months, viral load < 50 copies/mm(3, and CD4 ≥ 200 cells/mm(3, were consecutively enrolled at the outpatient clinic of Hospital de Clínicas, Porto Alegre, Brazil. Exclusion criteria were obesity, malnourishment, amputee, paraplegic, previous history of renal disease, pregnancy and hepatic insufficiency. Renal function was determined by estimated glomerular filtration rate (eGFR assessed by the modification of diet in renal disease. CKD was defined as an eGFR less or equal than 60 ml/min/1.73 m(2, for a period of at least 3 months. Poisson regression was used to determine factors associated with CKD. RESULTS: CKD was diagnosed in 8.4% of the population, and after adjustment, the risk factors were hypertension (RR = 3.88, 95%CI, 1.84-8.16, time on HAART (RR = 1.15, 95%CI,1.03-1.27 and tenofovir exposure (RR = 2.25, 95%CI, 1.04-4.95. Higher weight (RR = 0.88 95%CI, 0.82-0.96 was associated to normal function. CONCLUSIONS: CKD was a common finding in this cohort of patients and was related to hypertension, time on HAART and tenofovir exposure. We suggest a more frequent monitoring of renal function, especially for those with risk factors to early identify renal impairment.

    The concentrations of 11 phenols and 5 furans were measured in 12 categories of distilled spirits by HPLC methodology, together with the total antioxidant status (TAS) of the same beverages. Ellagic acid was the phenol present in highest concentration in all beverages. Moderate amounts of syringaldehyde, syringic acid, and gallic acid, as well as lesser amounts of vanillin and vanillic acid, were measurable in most samples of whiskey, brandy, and rum but were largely undetectable in gin, vodka, liqueurs, and miscellaneous spirits. 5-(Hydroxymethyl)furfural was the predominant furan in the former three beverages, notably cognac, with 2-furaldehyde the next highest, but these were undetectable in most of the latter beverages. Highest TAS values were given by armagnac, cognac, and bourbon whiskey, all three of which tended toward the highest concentrations of phenols. Negative TAS values were exhibited by rum, vodka, gin, and miscellaneous spirits in line with the low or undetectable phenol concentrations in these beverages. Wood aging is the most likely source of phenols and furans in distilled spirits. Those beverages exposed to this treatment contain significant antioxidant activity, which is between the ranges for white and red wines, with the potential to augment the antiatherosclerotic functions attributable to the ethanol that they contain.

    CT colonography (CTC) is a robust and reliable imaging test of the colon. Accuracy for the detection of colorectal cancer (CRC) is as high as conventional colonoscopy (CC). Identification of polyp is size dependent, with large lesions (≥10 mm) accurately detected and small lesions (6–9 mm) identified with moderate to good sensitivity.

    CT colonography (CTC) is a robust and reliable imaging test of the colon. Accuracy for the detection of colorectal cancer (CRC) is as high as conventional colonoscopy (CC). Identification of polyp is size dependent, with large lesions (≥10mm) accurately detected and small lesions (6-9mm) identified with moderate to good sensitivity.

    Purpose: To prospectively assess 5-year late toxicity in patients treated by concomitant radiochemotherapy for locally advanced oropharynx carcinoma using three different toxicity scales. Methods and Materials: A total of 226 patients were entered in a Phase III multicenter, randomized trial comparing radiotherapy alone (70 Gy in 35 fractions: Arm A) with concomitant radiochemotherapy (70 Gy in 35 fractions with three cycles of a 4-day regimen containing carboplatin and 5-fluorouracil: Arm B). Five living patients, free of local or distant recurrences, could not be evaluated for late toxicity. Forty-four patients were eligible for late toxicity with a median follow-up of 5 years. Late toxicity was evaluated by the radiation oncologist using a large questionnaire containing 120 mixed items of three scales (NCI-CTC, LENT/SOMA, and RTOG). The data were then transposed on separate scales using corresponding grades. Results: The 5-year overall survival rate was 22% in Arm B and 16% in Arm A (p=0.05). The 5-year locoregional control rate was 48% in Arm B and 25% in Arm A (p=0.002). The spinal cord was not affected by the concomitant adjunct of chemotherapy, and no deaths were caused by late toxicity. Using the three late toxicity scales, 100% of the patients treated with the combined modality (Arm B) developed one or more late complications vs. 94% in the radiotherapy-alone arm (Arm A). The difference was not statistically significant. The most commonly damaged organs (all Grade 1-4) were the salivary glands (100% in Arm B vs. 82% in Arm A, p<0.05), skin (78% vs. 47%, p<0.05), teeth (67% vs. 18%, p<0.05), mucosa (59% vs. 63% p = not significant), and mandible (44% vs. 12%, p<0.05). One or more Grade 3-4 complications occurred in 82% of the patients in Arm B vs. 47% in Arm A (p=0.02) but concerned only the teeth. The correlation between the RTOG and LENT/SOMA scale and between the NCI-CTC and LENT/SOMA scale were low for Grade 1-4 toxicity (near 30%). The transposability

    Introduction Une campagne de vaccination contre la méningite A avec le vaccin MenAfriVac a été organisée dans les quatre régions septentrionales du Togo du 28 novembre au 07 décembre 2014. L'approche CTC a été utilisée pour la première fois à une grande échelle pour la campagne de vaccination dans dix districts sanitaires du Togo. L'objectif de cette étude était d'estimer la couverture vaccinale et, de déterminer l'effet de l'utilisation de la Chaîne à Température Contrôlée (CTC) sur ces couvertures vaccinales. Méthodes L'enquête s'est déroulée du 9 au 14 mars 2015, soit environ 3 mois après la fin de la campagne de vaccination dans ces quatre régions. Le sondage en grappe à deux degrés stratifiés selon les régions a été utilisé. Dans 10 districts, le Togo a fait le choix d'utiliser le vaccin MenAfriVac en CTC. Résultats Au total, 2707 ménages ont été enquêtés et 9082 personnes âgées de 1 à 29 ans ont été interviewées. L'âge moyen des personnes enquêtées était de 11,8±7,7 ans et le sex-ratio (H/F) de 1,01. Le nombre moyen de personnes par ménage était de 5,7 et celui des personnes de 1 à 29 ans ciblées par la campagne était de 3,4. Sur les 9082 personnes enquêtées, 8889 (98%) étaient vaccinées. En analyse multivariée, les facteurs associés à la couverture vaccinale avec le MenAfrivac étaient la résidence dans la zone au moment de la campagne (aOR = 4,52 ; 95%IC = [4.07 - 4.97]) et le fait d'être informé de la campagne avant son démarrage (aOR=2,42 ; 95%IC = [2.05 - 2.80]). Par contre, la couverture vaccinale n'était pas différente selon la zone ayant utilisé l'approche CTC ou non (aOR=0,09 ; 95%IC = [-0,27-0,45]). Deux cent sept personnes interrogées (2,3%) ont déclaré avoir eu une Manifestation Adverse Post Immunisation (MAPI) après l'administration du vaccin. Il s'agissait surtout de MAPI mineures à type de fièvre, d'abcès et de gonflement au point d'injection. Conclusion Les r

    Major (unipolar) depression is one of the most common mental health disorders in children and adolescents, with an estimated one year prevalence of 4-5% in mid-late adolescence. Depression is probably the single most important risk factor for teenage suicide, the second to third leading cause of death in this age group and a forerunner of adult depressive disorder. Half of those with lifelong recurrent depression started to develop their symptoms before the age of 15 years. Family history is a well established risk factor and children born to depressed parents face three to four times increased rates of depression. Both genetic and environmental factors contribute to this risk. Adolescent girls are more vulnerable to depression in a ratio of 2:1. However, prepubertal depression has an equal sex ratio and is thought to be more strongly related to family dysfunction. Low mood is the predominant feature and depressed children might also have various unexplained physical symptoms, eating disorders, school refusal or substance misuse. Two thirds of adolescents with depression are thought to have at least one comorbid psychiatric disorder, most commonly the range of anxiety disorders, disruptive behavioural disorders and substance misuse problems. NICE highlights the importance of active listening and conversational techniques in order to screen for mood disorders effectively. The key questions used for screening are from the PHQ-2.

    With today’s unlimited and instantaneous communication, it is easy for a United States citizen to easily connect with anyone in the world. There are many positives to this; however, the unintended consequences include vulnerable people being influenced by radical ideologies. This is evident with the increase in homegrown violent extremists (HVE).The challenge for law enforcement is how to work with constitutional constraints that require a criminal predicate to be present in order to allow intelligence teams to continue collecting information in a permanent file.

    We demonstrate that a quantum particle, initially prepared in a quantum well, can propagate through a reservoir with a continuous spectrum and reappear in a distant well without being registered in the reservoir. It is shown that such a passage through the reservoir takes place even if the latter is continuously monitored. We discuss a possible experimental realization of such a teleportation phenomenon in mesoscopic systems.

    Patients with differentiated thyroid carcinoma are submitted to a first assessment several months after initial therapy to evaluate their response to treatment. At that assessment, measurement of basal thyroglobulin (Tg) and antithyroglobulin antibodies (TgAb) and neck ultrasonography (US) are recommended. Serum Tg may be falsely negative in the presence of TgAb, and the management of patients with negative Tg but positive TgAb represents a challenge. The objective of this study was to correlate the variation in TgAb concentrations (comparison before and after ablation with (131)I) with the risk of structural disease. The sample consisted of 116 low- or intermediate-risk patients who had undetectable Tg, negative US at initial assessment, and positive TgAb 8-12 months after thyroidectomy and ablation with (131)I. Comparison of TgAb concentrations before and after ablation with (131)I showed a reduction of >50% in 56 patients (group A), a reduction of nodes in two, pulmonary in two, and bone in one). They were diagnosed in 0/56, 2/35 (5.7%), and 3/25 (12%) patients of groups A, B, and C, respectively. During follow-up, metastases were detected in 7/111 (6.3%) patients (lymph nodes in six, and pulmonary in one). They occurred in 1/56 (1.8%), 3/33 (9%), and 3/22 (13.6%) patients of groups A, B, and C, respectively. Thus, structural disease was found in 1.8%, 14.3%, and 24% of groups A, B, and C, respectively. This rate was 4% in low-risk patients and 15.4% in intermediate-risk patients. Among patients with undetectable Tg, negative US, and positive TgAb after ablation with (131)I, the frequency of structural disease was 50% reduction in TgAb. Among patients without a significant reduction in TgAb, approximately 10% of low-risk patients and >20% of intermediate-risk patients had structural disease. These results help define the indication for imaging methods other than US during initial assessment and long-term follow-up.

    Hepatitis B surface antigen (HBsAg)-negative/hepatitis B core antibody (HBcAb)-positive patients with undetectable serum hepatitis B virus (HBV) DNA have experienced and resolved hepatitis B virus (HBV) infection. Lymphoma patients with resolved HBV infection have high risk of HBV reactivation when treated with robust immunosuppressive agents, but the reported rate varies extensively between different studies. This study aims to estimate the risk of HBV reactivation in HBsAg-negative/HBcAb-positive patients receiving rituximab-containing chemotherapy for lymphoma. Databases were searched for papers published in English until 8 August 2016. The pooled risk of HBV reactivation was estimated using a random-effects model. Data from 15 studies were retrieved, including a total of 1312 HBsAg-negative/HBcAb-positive lymphoma patients treated with rituximab-containing chemotherapy. The results revealed HBV reactivation rate of 9.0 % [95 % confidence interval (CI) 0.05-0.15].

In addition, sources of iodine nutrition (i.e., water and salt were investigated. A school-based cross-sectional survey of children aged 6–12 years was conducted in three primary schools of Nauru. Urinary iodine concentration (UIC was determined by spot urine samples. Available water and salt samples in Nauru were collected for the measurement of iodine content. A food frequency questionnaire was conducted. The median UIC was 142 μg/L, and 25.2% and 7.4% of the population had median UIC below 100 μg/L and 50 μg/L, respectively. Natural iodine-containing foods such as seaweeds and agar were rare. Iodine was undetectable in Nauruan tank water, filtered tap water, and raindrops. Of the analyzed salt products, five kinds were non-iodized, and three were iodized (iodine content: 15 ppm, 65 ppm, and 68 ppm, respectively. The results indicate that the iodine status in Nauruan school children is adequate. Iodized salt may serve as an important source of iodine nutrition in Nauru.

    Purpose Delayed intensification (DI) is an integral part of treatment of childhood acute lymphoblastic leukemia (ALL), but it is associated with relevant toxicity. Therefore, standard-risk patients of trial AIEOP-BFM ALL 2000 (Combination Chemotherapy Based on Risk of Relapse in Treating Young Patients With ALL) were investigated with the specific aim to reduce treatment intensity. Patients and Methods Between July 2000 and July 2006, 1,164 patients (1 to 17 years of age) with standard-risk ALL (defined as the absence of high-risk cytogenetics and undetectable minimal residual disease on days 33 and 78) were randomly assigned to either experimental reduced-intensity DI (protocol III; P-III) or standard DI (protocol II; P-II). Cumulative drug doses of P-III were reduced by 30% for dexamethasone and 50% for vincristine, doxorubicin, and cyclophosphamide, which shortened the treatment duration from 49 to 29 days. The study aimed at noninferiority of reduced-intensity P-III; analyses were performed according to treatment given. Results For P-III and P-II, respectively, the 8-year rate of disease-free survival (± SE) was 89.2 ± 1.3% and 92.3 ± 1.2% ( P = .04); cumulative incidence of relapse, 8.7 ± 1.2% and 6.4 ± 1.1% ( P = .09); and overall survival, 96.1 ± 0.8% and 98.0 ± 0.6% ( P = .06). Patients with ETV6-RUNX1-positive ALL and patients 1 to 6 years of age performed equally well in both arms. The incidence of death during remission was comparable, which indicates equivalent toxicity. The 8-year cumulative incidence rate of secondary malignancies was 1.3 ± 0.5% and 0.6 ± 0.4% for P-III and P-II, respectively ( P = .37). Conclusion Although the criteria used for the standard-risk definition in this trial identified patients with exceptionally good prognosis, reduction of chemotherapy was not successful mainly because of an increased rate of relapse. The data suggest that treatment reduction is feasible in specific subgroups, which underlines the biologic

This research is an explorative and descriptive study on the socio-cultural aspects of food system. The data were collected through a direct interview and discussion with respondents as well as a direct observation at the location of respondents. A sample size of 338 households was drawn from the population. To obtain the data on the cultural aspects, history and  socio aspect of food, in-depth interviews was conducted with 19 key persons. The study was last for 12 months. In Outer Baduy, the factors significantly related to nutritional status are age, number of household size, income, nutritional knowledge, and wife’s ability to read. In Moslem Baduy, only age and income are related to the nutritional status of children. In Moslem Baduy and the Outer Baduy, the correlation between age and W/A or W/H is similar: namely, the higher the age, the lower would the Z-score for the W/A or W/H. The income is significantly correlated to the child nutritional status according to Z-score for W/A with a high correlation coefficient, that is, 0.61. This means that the higher the income, the higher would be the Z-score value for the W/A.  The distribution of adults according to BMI classification in Outer Baduy it shows that 12.7% husbands and 17.6% wives are thin (wasted, while the

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide

    Full Text Available Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED, i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits.

    Full Text Available Social hierarchy is a fact of life for many animals. Navigating social hierarchy requires understanding one's own status relative to others and behaving accordingly, while achieving higher status may call upon cunning and strategic thinking. The neural mechanisms mediating social status have become increasingly well understood in invertebrates and model organisms like fish and mice but until recently have remained more opaque in humans and other primates. In a new study in this issue, Noonan and colleagues explore the neural correlates of social rank in macaques. Using both structural and functional brain imaging, they found neural changes associated with individual monkeys' social status, including alterations in the amygdala, hypothalamus, and brainstem--areas previously implicated in dominance-related behavior in other vertebrates. A separate but related network in the temporal and prefrontal cortex appears to mediate more cognitive aspects of strategic social behavior. These findings begin to delineate the neural circuits that enable us to navigate our own social worlds. A major remaining challenge is identifying how these networks contribute functionally to our social lives, which may open new avenues for developing innovative treatments for social disorders.

    2016-02-01

    Assessing the mental status of patients with a neurobehavioral disorder is a critical element in the diagnosis and treatment of these patients. This assessment should always be performed after the patient's history it taken and a general physical as well as a neurologic examination is completed. The mental status examination commences with observing the patient's appearance and level of consciousness. The examiner should also pay attention to patient's social behavior, emotional state and mood. There are 3 major means of assessing a patient's mental status. One type attempts to determine if the patient is demented and the severity of the dementia as it pertains to their ability to perform activities of daily living as well as instrumental activities. A second type of assessment utilizes what may be termed as "screening tests" or "omnibus tests". These brief tests are performed independent of the patient's history and examination. The two most frequently used screening tests are the Mini-Mental Status Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). The third means of assessing a patient's mental status is by using specific neuropsychological tests that focus on specific domains of cognition, such as frontal executive functions, attention, episodic verbal and visuospatial memory, declarative knowledge such as language (speech, reading and writing) and arithmetical, as well as visuospatial and perceptual abilities. These neurobehavioral, neuropsychiatric and neuropsychological assessments of patients with a cognitive decline and behavioral abnormalities should often be accompanied by laboratory tests, and neuroimaging that can help determine the underlying pathologic process so that effective therapeutic and management approaches can be provided.

  19. Status of memory loss.

    2012-01-01

    A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

    Effective maintenance will be an essential ingredient in determining fusion system productivity. This level of productivity will result only after close attention is paid to the entire system as an entity and appropriate integration of the elements is made. The status of fusion maintenance is reviewed in the context of the entire system. While there are many challenging developmental tasks ahead in fusion maintenance, the required technologies are available in several high-technology industries, including nuclear fission

    2001-01-01

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M and O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    The experimental and theoretical status of hadronic molecules, which are weakly-bound states of two or more hadrons are summarized. A brief history of the subject is given, and a few good candidates are discussed. Some signatures for molecules which may be of interest in the classification of possible molecule states are studied. It is shown that a more general understanding of 2 → 2 hadron-hadron scattering amplitudes will be crucial for molecule searches. A few more recent molecule candidates which are not well established as molecules but satisfy some of the expected signatures are also discussed. (author). 50 refs

    Baltadjiev, D.; Charakchiev

    2000-01-01

    Tele-radiology is a term becoming increasingly popular in the medical literature. Nevertheless, terminological definitions in this particular field are still rather vague. The scope of applications extend from simple image presenting via analogue telephone lines to transmission of 3-D medical images through a satellite. It is a matter of standards highly differing in terms of data transmission rates, safety, technical demands on the systems and the like. In this article new information technologies, technical aspects, as well as some major applications of tele-radiology are discussed. The current status of tele-medicine/tele-radiology in this country is likewise briefly outlined

    To investigate the impact of a spoken language intervention curriculum aiming to improve the language environments caregivers of low socioeconomic status (SES) provide for their D/HH children with CI & HA to support children's spoken language development. Quasiexperimental. Tertiary. Thirty-two caregiver-child dyads of low-SES (as defined by caregiver education ≤ MA/MS and the income proxies = Medicaid or WIC/LINK) and children aged curriculum designed to improve D/HH children's early language environments. Changes in caregiver knowledge of child language development (questionnaire scores) and language behavior (word types, word tokens, utterances, mean length of utterance [MLU], LENA Adult Word Count (AWC), Conversational Turn Count (CTC)). Significant increases in caregiver questionnaire scores as well as utterances, word types, word tokens, and MLU in the treatment but not the control group. No significant changes in LENA outcomes. Results partially support the notion that caregiver-directed language enrichment interventions can change home language environments of D/HH children from low-SES backgrounds. Further longitudinal studies are necessary.

  15. Age, relationship status, and the planning status of births

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available In the United States historically, births to older mothers have been more likely to be planned than births to younger mothers, and births to unmarried women have been less likely to be planned than births to married women. As the average age of mothers has increased and more births have occurred outside of marriage in the United States, the intersection of these trends may have weakened the traditional linkage between age and birth planning status. In this article, we examine differences by maternal age in planning status of births using The 2002 National Survey of Family Growth. We find that age is strongly associated with planning status, but the association is reduced in magnitude when controlling for relationship status and is stronger for first and second births than for higher-parity births. Further, the association between union status and the planning status of births varies by race-ethnicity.

    Background Psychosocial processes are implicated as mediators of racial/ethnic health disparities via dysregulation of physiological responses to stress. Our aim was to investigate the extent to which factors previously documented as buffering the impact of high-risk family environments on Aboriginal youths’ psychosocial functioning were similarly beneficial for their physical health status. Method and Results We examined the relationship between psychosocial resilience and physical health of urban Aboriginal youth (12–17 years, n = 677) drawn from a representative survey of Western Australian Aboriginal children and their families. A composite variable of psychosocial resilient status, derived by cross-classifying youth by high/low family risk exposure and normal/abnormal psychosocial functioning, resulted in four groups- Resilient, Less Resilient, Expected Good and Vulnerable. Separate logistic regression modeling for high and low risk exposed youth revealed that Resilient youth were significantly more likely to have lower self-reported asthma symptoms (OR 3.48, padaptation that impact on the physical health of Aboriginal youth. The results support the posited biological pathways between chronic stress and physical health, and identify the protective role of social connections impacting not only psychosocial function but also physical health. Using a resilience framework may identify potent protective factors otherwise undetected in aggregated analyses, offering important insights to augment general public health prevention strategies.

    Vitamin D deficiency is common in tuberculosis (TB) and this may modulate immune responses. Objective To determine vitamin D status in patients with TB and examine sources of vitamin D in Tbilisi, Georgia. Research Methods and Procedures We measured plasma 25-hydroxyvitamin D (25(OH)D) and dietary vitamin D intake in pulmonary TB patients (n=85) in Tbilisi, Georgia. To determine the impact of season on vitamin D status, we tested in vitro conversion of 7-dehydrocholesterol (7-DHC) to previtamin D3 after sunlight exposure. Results In TB subjects, mean plasma 25(OH)D concentrations were 14.5 ± 7.0 ng/mL, and vitamin D insufficiency (25(OH)D vitamin D were mainly fish, eggs, and butter. Daily intake was well below recommended daily intakes in TB subjects (172 IU + 196 IU). The conversion of 7-DHC to previtamin D3 was undetectable between October to March, and highest in June and July between 11:00 and 14:00 h. Conclusion Insufficient vitamin D dietary intake and limited production of vitamin D from sunlight during the majority of the year, may explain the high prevalence of vitamin D insufficiency TB patients in Tbilisi.

    This report summarizes the experimental and theoretical status of hadronic molecules, which are weakly-bound states of two or more hadrons. We begin with a brief history of the subject and discuss a few good candidates, and then abstract some signatures for molecules which may be of interest in the classification of possible molecule states. Next we argue that a more general understanding of 2 → 2 hadron-hadron scattering amplitudes will be crucial for molecule searches, and discuss some of our recent work in this area. We conclude with a discussion of a few more recent molecule candidates (notably the f o (1710)) which are not well established as molecules but satisfy some of the expected signatures. (Author)

    Originally started in 2012 as the Betelgeuse Project, interest in the other bright stars of Orion soon expanded the Project stars to include a total of six of the brightest stars in Orion. The name was then changed to the Orion Project. Orion is one of the most famous constellations. Its declination along the celestial equator is such that it is visible from most of northern and southern hemispheres. In addition, the stars of Orion are very bright and interesting. The Orion Project now includes the stars Betelgeuse, Rigel, Saiph and the three stars of Orion's belt, Mintaka, Alnilam and Alnitak. The projects objectives are both to help the observer produce quality photometric and spectroscopic data and to produce archival quality photometric (BVRIJH bands) and spectroscopy (low, mid and high-resolution) data. This paper is a summary of the Orion Project status.

    2012-01-01

    The experiments at the Large Hadron Collider will have to deal with unprecedented radiation levels. The design of the CMS forward calorimetry detector (HF) is now finalized. The present design of CMS calls for the HF calorimeter to be based on quartz fiber technology. It consists of two modules, located symmetrically at about 11 meters from either side of interaction point. They cover the pseudorapidity range 3-5. The length along the beam is 1.65m or 10 nuclear interaction lenghts. Each calorimeter consists of a large steel block that serves as the absorber. Embedded quartz fibers in the steel absorber run parallel to the beam and constitute the active component of the detector. In order to optimize energy resolution for E and ET flows and forward jets, the calorimeter is effectively segmented longitudinally by using two different fiber lengths. The present status will be discussed.

    The status of French reactors is reviewed. The ORPHEE and RHF reactors can not be operated with a LEU fuel which would be limited to 4.8 g U/cm 3 . The OSIRIS reactor has already been converted to LEU. It will use U 3 Si 2 as soon as its present stock of UO 2 fuel is used up, at the end of 1994. The decision to close down the SILOE reactor in the near future is not propitious for the start of a conversion process. The REX 2000 reactor, which is expected to be commissioned in 2005, will use LEU (except if the fast neutrons core option is selected). Concerning the end of the HEU fuel cycle, the best option is reprocessing followed by conversion of the reprocessed uranium to LEU

  11. Biomarkers of Selenium Status

    Directory of Open Access Journals (Sweden)

    Gerald F. Combs, Jr.

    2015-03-01

    Full Text Available The essential trace element, selenium (Se, has multiple biological activities, which depend on the level of Se intake. Relatively low Se intakes determine the expression of selenoenzymes in which it serves as an essential constituent. Higher intakes have been shown to have anti-tumorigenic potential; and very high Se intakes can produce adverse effects. This hierarchy of biological activities calls for biomarkers informative at different levels of Se exposure. Some Se-biomarkers, such as the selenoproteins and particularly GPX3 and SEPP1, provide information about function directly and are of value in identifying nutritional Se deficiency and tracking responses of deficient individuals to Se-treatment. They are useful under conditions of Se intake within the range of regulated selenoprotein expression, e.g., for humans <55 μg/day and for animals <20 μg/kg diet. Other Se-biomarkers provide information indirectly through inferences based on Se levels of foods, tissues, urine or feces. They can indicate the likelihood of deficiency or adverse effects, but they do not provide direct evidence of either condition. Their value is in providing information about Se status over a wide range of Se intake, particularly from food forms. There is need for additional Se biomarkers particularly for assessing Se status in non-deficient individuals for whom the prospects of cancer risk reduction and adverse effects risk are the primary health considerations. This would include determining whether supranutritional intakes of Se may be required for maximal selenoprotein expression in immune surveillance cells. It would also include developing methods to determine low molecular weight Se-metabolites, i.e., selenoamino acids and methylated Se-metabolites, which to date have not been detectable in biological specimens. Recent analytical advances using tandem liquid chromatography-mass spectrometry suggest prospects for detecting these metabolites.

  13. Incidence of previously undetected disease in routine paediatric otolaryngology admissions.

    Zeitoun, H; Robinson, P

    1996-06-01

    The process of clerking routine pre-operative admissions involves the house officer taking a full medical history and performing a full physical examination. The diagnostic yield is thought to be low, and the educational value to the house officer is also small. This study addresses the question as to whether routine physical examination is always indicated. One hundred and nine children admitted for routine Otolaryngology procedures were prospectively studied to identify the importance of examination in the pre-operative assessment of patients. The results showed that 51 per cent of the children admitted had risk factors. The medical history was sufficient to identify these risk factors in all patients with the exception of one cardiac condition. This study concludes that a suitable alternative to the current process of clerking such as a standardized nurse history could be safely and efficiently undertaken. Eliminating the tiny percentage of previously unrecognized disease would be a prerequisite for such a change.

    The process of single-hair transplanting, though providing obvious cosmetic advantages in hairline refinement, has long been considered too tedious and time consuming to be incorporated into standard transplant sessions. Micrograft dilators provide dilatation, organization, and hemostasis, while permitting large numbers of micrografts to be placed quickly and effortlessly below the standard transplanted hairline.

    Both endocarditis and Bartonella infections are neglected public health problems, especially in rural Asia. Bartonella endocarditis has been described from wealthier countries in Asia, Japan, Korea, Thailand and India but there are no reports from poorer countries, such as the Lao PDR (Laos), probably because people have neglected to look. We conducted a retrospective (2006-2012), and subsequent prospective study (2012-2013), at Mahosot Hospital, Vientiane, Laos, through liaison between the microbiology laboratory and the wards. Patients aged >1 year admitted with definite or possible endocarditis according to modified Duke criteria were included. In view of the strong suspicion of infective endocarditis, acute and convalescent sera from 30 patients with culture negative endocarditis were tested for antibodies to Brucella melitensis, Mycoplasma pneumoniae, Bartonella quintana, B. henselae, Coxiella burnetii and Legionella pneumophila. Western blot analysis using Bartonella species antigens enabled us to describe the first two Lao patients with known Bartonella henselae endocarditis. We argue that it is likely that Bartonella endocarditis is neglected and more widespread than appreciated, as there are few laboratories in Asia able to make the diagnosis. Considering the high prevalence of rheumatic heart disease in Asia, there is remarkably little evidence on the bacterial etiology of endocarditis. Most evidence is derived from wealthy countries and investigation of the aetiology and optimal management of endocarditis in low income countries has been neglected. Interest in Bartonella as neglected pathogens is emerging, and improved methods for the rapid diagnosis of Bartonella endocarditis are needed, as it is likely that proven Bartonella endocarditis can be treated with simpler and less expensive regimens than "conventional" endocarditis and multicenter trials to optimize treatment are required. More understanding is needed on the risk factors for Bartonella endocarditis and the importance of vectors and vector control.

    Is there any occurrence of hidden (occult) endometriotic lesions in normal peritoneum of women with and without visible endometriosis? We detected a slightly higher occurrence of occult microscopic endometriosis (OME) in normal peritoneum of women with visible endometriosis than in control women. Based on a small number of cases, the concept of invisible microscopic endometriosis in visually normal peritoneum has been reported for more than a decade but there is controversy regarding their tissue activity and clinical significance. This case-controlled research study was conducted with prospectively collected normal peritoneal samples from 151 women with and 62 women without visible endometriosis. Normal peritoneal biopsy specimens from different pelvic sites of were collected during laparoscopy. A histological search of all peritoneal biopsy specimens for the detection of invisible endometriosis was done by immunoreaction to Ber-EP4 (epithelial cell marker), CD10 (stromal cell marker) and Calretinin (mesothelial cell marker). Tissue expression of estrogen/progesterone receptors (ER/PR) and cell proliferation marker, Ki-67, was performed by immunohistochemistry to identify tissue activity. Three different patterns of OME were detected based on (I) the presence of typical gland/stroma, (II) reactive hyperplastic change of endometrioid epithelial cells with surrounding stroma and (III) single-layered epithelium-lined cystic lesions with surrounding stroma. A higher tendency toward the occurrence of OME was found in women with visible endometriosis (15.2%, 23/151) compared with control women (6.4%, 4/62) (P = 0.06, χ(2) test). The epithelial cells and/or stromal cells of OME lesions were immunoreactive to Ber-EP4 and CD10 but not reactive to Calretinin. ER and PR expression was observed in all patterns of OME lesions. Ki-67 index was significantly higher in pattern I/II OME lesions than in pattern III OME lesions (Pendometriosis due to the presence of adhesions in the pelvis. We re-confirmed a decade long old concept of invisible (occult) endometriosis in visually normal peritoneum of women with visible endometriosis. The existence of a variable amount of tissue activity in these occult lesions may contribute to the recurrence/occurrence of endometriosis or persistence/recurrence of pain manifestation in women even after successful ablation or excision of visible lesions by laparoscopy. This work was supported in part by Grants-in-aid for Scientific Research from the Japan Society for the Promotion of Science. There is no conflict of interest related to this study. Not applicable.

    Full Text Available While in Europe vodka is mainly derived from potatoes or cereals, a large proportion of Brazilian vodka is likely obtained from sugarcane, which contains ethyl carbamate (EC precursors. EC, in addition to several other contaminants and congeners, were investigated in 32 samples of Brazilian vodka. All samples complied with the Brazilian regulations for congeners and contaminants, having EC content below 0.01 mg/L (detection limit. These results are probably related to the processing of vodka, in particular the use of extractive and rectifying stainless steel distillation columns, which allow the production of high strength spirits with low levels of congeners and contaminants.

    2014-07-01

    Biologic products are being developed over the past three decades. The expiry of patent protection for many biological medicines has led to the development of biosimilars in UK or follow on biologics in USA. This article reviews the literature on biosimilar drugs that covers the therapeutic status and regulatory guidelines. Appraisal of published articles from peer reviewed journals for English language publications, search from PubMed, and guidelines from European Medicines Agency, US Food Drug Administration (FDA) and India were used to identify data for review. Literature suggest that biosimilars are similar biological products, i.e., comparable but not identical to the reference product, are not generic version of innovator product and do not ensure therapeutic equivalence. Biosimilars present more challenges than conventional generics and marketing approval is also more complicated. To improve access, US Congress passed the Biologics Price Competition and Innovation act 2009 and US FDA allowed "abbreviated pathway" for their approval. U.S law has defined new standards and terms and EMA scientific guidelines have also set detailed approval standards. India being one of the most preferred manufacturing destinations of biosimilars, there is a need for stringent safety and regulatory guidelines. The New India Guidelines "Draft Guidelines on Similar Biologics were announced in June 2012, by Department of Biotechnology at Boston bio and available online.

    The Laser Integration Line (LIL) was first designed as a prototype to validate the concepts and the laser architecture of the Laser MegaJoule (LMJ). The LIL facility is a 4-beam laser representing a quad structure of the LMJ. A set of test campaigns were conducted to safely ramp up laser performance. The main goal was to measure quad-specific features such as beam synchronization and focal spot (size, smoothing contrast ratio or irradiation nonuniformity) versus the LMJ requirements. Following the laser commissioning, the LIL has become a major instrument dedicated to the achievement of plasma physics experiments for the French Simulation Program and was also opened to the academic scientific community. One of the attributes of the LIL facility is to be very flexible to accommodate the requests of plasma physicists during campaigns. The LIL is constantly evolving to best meet the needs of target physicists. Changes made or planned are either to improve the quality of laser beams, or to increase the LIL Energy-Power operating space. To optimize preparation and design of shot campaigns, the LIL performance status has been elaborated. It gives information about the characteristics of the laser in terms of near field and far field, defines the steps to maintain performance, explains how the facility responds to the request, details settings (smoothing, shaping of the focal spot, energy, temporal pulse shaping, beam pointing) and gives the limits in energy and power. In this paper, an overview of the LIL performance is presented. (authors)

    Faester, S.; Hansen, N.; Huang, X.; Juul Jensen, D.; Ralph, B.

    2012-01-01

    Nanometals and nanotechnology have over the years been covered in papers, books and conferences - also in many Risoe International Symposia, where the 30th in 2009 dealt solely with nanostructured metals. Since then, rapid progress has been made in synthesis, characterization and modeling, and it is timely to discuss status and perspective also with a view on applications in an international forum such as the Risoe Symposium. Both keynote and contributed papers address important current problems illustrating global research and development in this field. Examples are the development of new synthesis techniques followed by characterization and modeling of microstructures both in 2D and 3D now starting to bridge the micrometer scales. The vital area of mechanical behavior is addressed by the development of new testing techniques and a broad effort to characterize and model mechanical properties of metals strengthened by dislocations and twins. This research has now led to new understanding of both strengthening mechanisms and strengh structure relationships based on experiments in combination with analytical and numerical modeling. The holistic approach to research on nanometals demonstrated by these proceedings can guide both scientists and technologists in their future work also with the aim of introducing into society this new group of advanced materials. Such an effort is important, as science and technology today is significantly affected by politics of governments and international institutions, and therefore a new initiative in the pressent is to include a discussion of research and development in the area of nanometals i USA, China and Japan.

  3. Biocatalysis: A Status Report.

    Bommarius, Andreas S

    2015-01-01

    This review describes the status of the fields of biocatalysts and enzymes, as well as existing drawbacks, and recent advances in the areas deemed to represent drawbacks. Although biocatalysts are often highly active and extremely selective, there are still drawbacks associated with biocatalysis as a generally applicable technique: the lack of designability of biocatalysts; their limits of stability; and the insufficient number of well-characterized, ready-to-use biocatalysts. There has been significant progress on the following fronts: (a) novel protein engineering tools, both experimental and computational, have significantly enhanced the toolbox for biocatalyst development. (b) The deactivation of biocatalysts under various stresses can be described quantitatively via rational models. There are several cases of spectacular leaps of stabilization after accumulating all stabilizing mutations found in earlier rounds. The concept that stabilization against one type of stress commonly also stabilizes against other types of stress is now experimentally considerably better founded than a few years ago. (c) A host of developments of novel biocatalysts in the past few years, in part fueled by improved designability and improved methods of stabilization, has considerably broadened the toolbox for synthetic chemistry.

  4. Status of fusion technology

    The current status of fusion technology is surveyed. Limited reserves of fossil fuel and dangers of proliferation from nuclear reactors have brought into focus the need to develop an optional energy source. Fusion is being looked upon as an optional energy source which is free from environmental hazards unlike fossil fuels and nuclear reactors. Investments in R and D of fusion energy have increased rapidly in USA, Japan, USSR and European countries. Out of the various fusion fuels known, a mixture of D and T is widely chosen. The main problem in fusion technology is the confinement of plasma for a time sufficient to start the fusion reaction. This can be done magnetically or inertially. The three approaches to magnetic confinement are : (1) tokamak, (2) mirror and (3) pinch. Inertial confinement makes use of lasers or electron beams or ion beams. Both the methods of confinement i.e. magnetic and inertial have problems which are identified and their nature is discussed. (M.G.B.)

    Full Text Available The detection and separation of circulating tumor cells (CTCs are crucial in early cancer diagnosis and cancer prognosis. Filtration through a thin film is one of the size and deformability based separation methods, which can isolate rare CTCs from the peripheral blood of cancer patients regardless of their heterogeneity. In this paper, volume of fluid (VOF multiphase flow models are employed to clarify the cells’ filtering processes. The cells may deform significantly when they enter a channel constriction, which will induce cell membrane stress and damage if the area strain is larger than the critical value. Therefore, the cellular damage criterion characterized by membrane area strain is presented in our model, i.e., the lysis limit of the lipid bilayer is taken as the critical area strain. Under this criterion, we discover that the microfilters with slit-shaped pores do less damage to cells than those with circular pores. The influence of contact angle between the microfilters and blood cells on cellular injury is also discussed. Moreover, the optimal film thickness and flux in our simulations are obtained as 0.5 μm and 0.375 mm/s, respectively. These findings will provide constructive guidance for the improvement of next generation microfilters with higher throughput and less cellular damage.

    Full Text Available This contribution deals with unfree labour in Germany from the early modern age until the beginning of the 20th century. It presents the main conclusions of a book published in 2013 on this subject in German. Unfree labour is not identified in the first place with slavery or any other labour relationship based on status. Instead, this study aims at an analysis of freedom and coercion in contractual labour relationships. It will be argued that in Germany contractual labour relationships before 1800 were embedded in a legal system that strongly restricted contractual autonomy and aimed at the suppression of free labour markets. The scope of this legislation was to guarantee efficient labour performance, which was not only perceived as being in the personal interest of an employer, but as a fundamental element of the common good. After 1800 the system changed to more incentive-based legislation that established freedom of contract for labour relations. Nevertheless, coercion in order to perform the contractual duties of a work contract remained important for many groups of workers, especially farmhands and industrial workers. The last criminal sanctions for breaches of labour contracts were only abolished in the revolution of 1919. This development shows the difficulties German law had in extending the principles of private law to workers. When a system of free labour was fully established, the issue of unemployment and economic problems, especially in the Weimar Republic, required a new system of protective rules. The history of free market based labour contracts in Germany was therefore very short, with state intervention shi ing from control and coercion to social assistance.

    Although a number of studies have been conducted in various countries to evolve reactor systems based on thorium fuel cycle, its use, so far, is limited to only a few reactors. However, for countries having large reserves of thorium, its utilization is of great significance for their nuclear power programmes. Reasonably assured world resources of thorium in the lower price range have been estimated at more than 500,000 tons of ThO 2 . While most of these resources are in placer deposits in various parts of the world, some vein deposits and uranium ores are other important sources of thorium. Monazite, the most important mineral of thorium, is found in the beach sand deposits along with other heavy minerals like ilmenite, rutile, zircon, and sillimanite etc. Mining of these deposits is usually carried out by suction dredging and separation of monazite from other minerals is effected by a combination of magnetic, electrostatic and gravity separation techniques. Chemical processing of monazite is carried out either by sulphuric acid or caustic treatment, followed by separation of the rare earths and thorium by partial precipitation or leaching. The thorium concentrate is further processed to obtain mantle grade thorium nitrate by chemical purification steps whereas solvent extraction using TBP is adopted for making nuclear-grade material. The purified thorium nitrate is converted to the oxide usually by precipitation as oxalate followed by calcination. The oxide is reduced directly with calcium or converted to the chloride or fluoride and then reduced by calcium or magnesium to obtain thorium metal. Various fuel designs based on the metal or its alloys, mixed oxides or carbides, and dispersed type fuel elements have been developed and accordingly, different fabrication techniques have been employed. Work on irradiation of thorium containing fuel elements and separation of U 233 is being carried out. This paper reviews the status of thorium technology in the world with

    At the end of engineering design activities (EDA) in July 2001, all the essential elements became available to make a decision on construction of ITER. A sufficiently detailed and integrated engineering design now exists for a generic site, has been assessed for feasibility, and costed, and essential physics and technology R and D has been carried out to underpin the design choices. Formal negotiations have now begun between the current participants--Canada, Euratom, Japan, and the Russian Federation--on a Joint Implementation Agreement for ITER which also establishes the legal entity to run ITER. These negotiations are supported on technical aspects by Coordinated Technical Activities (CTA), which maintain the integrity of the project, for the good of all participants, and concentrate on preparing for procurement by industry of the longest lead items, and for formal application for a construction license with the host country. This paper highlights the main features of the ITER design. With cryogenically-cooled magnets close to neutron-generating plasma, the design of shielding with adequate access via port plugs for auxiliaries such as heating and diagnostics, and of remote replacement and refurbishing systems for in-vessel components, are particularly interesting nuclear technology challenges. Making a safety case for ITER to satisfy potential regulators and to demonstrate, as far as possible at this stage, the environmental attractiveness of fusion as an energy source, is also important. The paper gives illustrative details on this work, and an update on the progress of technical preparations for construction, as well as the status of the above negotiations

    Findings from uncontrolled studies suggest that addition of pegylated interferon in patients with HBe antigen (HBeAg)-negative chronic hepatitis B receiving nucleos(t)ide analogues with undetectable plasma hepatitis B virus (HBV) DNA might increase HBs antigen (HBsAg) clearance. We aimed to assess this strategy. In this randomised, controlled, open-label trial, we enrolled patients aged 18-75 years with HBeAg-negative chronic hepatitis B and documented negative HBV DNA while on stable nucleos(t)ide analogue regimens for at least 1 year from 30 hepatology tertiary care wards in France. Patients had to have an alanine aminotransferase concentration of less than or equal to five times the upper normal range, no hepatocellular carcinoma, and a serum α fetoprotein concentration of less than 50 ng/mL, normal dilated fundus oculi examination, and a negative pregnancy test in women. Patients with contraindications to pegylated interferon were not eligible.

    The report gives an account of the development of material and fabrication technology for copper canisters with cast inserts during the period from 2000 until the start of 2004. The engineering design of the canister and the choice of materials in the constituent components described in previous status reports have not been significantly changed. In the reference canister, the thickness of the copper shell is 50 mm. Fabrication of individual components with a thinner copper thickness is done for the purpose of gaining experience and evaluating fabrication and inspection methods for such canisters. As a part of the development of cast inserts, computer simulations of the casting processes and techniques used at the foundries have been performed for the purpose of optimizing the material properties. These properties have been evaluated by extensive tensile testing and metallographic inspection of test material taken from discs cut at different points along the length of the inserts. The testing results exhibit a relatively large spread. Low elongation values in certain tensile test specimens are due to the presence of poorly formed graphite, porosities, slag or other casting defects. It is concluded in the report that it will not be possible to avoid some presence of observed defects in castings of this size. In the deep repository, the inserts will be exposed to compressive loading and the observed defects are not critical for strength. An analysis of the strength of the inserts and formulation of relevant material requirements must be based on a statistical approach with probabilistic calculations. This work has been initiated and will be concluded during 2004. An initial verifying compression test of a canister in an isostatic press has indicated considerable overstrength in the structure. Seamless copper tubes are fabricated by means of three methods: extrusion, pierce and draw processing, and forging. It can be concluded that extrusion tests have revealed a

  18. Conceptions of nuclear threshold status

    Quester, G.H.

    1991-01-01

    This paper reviews some alternative definitions of nuclear threshold status. Each of them is important, and major analytical confusions would result if one sense of the term is mistaken for another. The motives for nations entering into such threshold status are a blend of civilian and military gains, and of national interests versus parochial or bureaucratic interests. A portion of the rationale for threshold status emerges inevitably from the pursuit of economic goals, and another portion is made more attraction by the derives of the domestic political process. Yet the impact on international security cannot be dismissed, especially where conflicts among the states remain real. Among the military or national security motives are basic deterrence, psychological warfare, war-fighting and, more generally, national prestige. In the end, as the threshold phenomenon is assayed for lessons concerning the role of nuclear weapons more generally in international relations and security, one might conclude that threshold status and outright proliferation coverage to a degree in the motives for all of the states involved and in the advantages attained. As this paper has illustrated, nuclear threshold status is more subtle and more ambiguous than outright proliferation, and it takes considerable time to sort out the complexities. Yet the world has now had a substantial amount of time to deal with this ambiguous status, and this may tempt more states to exploit it

    Chronic lymphocytic leukemia (CLL) is a lymphoproliferative disorder of remarkable heterogeneity as demonstrated by cytogenetics and molecular analyses. Complex karyotype (CK), TP53 deletions and/or mutations (TP53 disruption), IGVH mutational status, and, more recently, recurrent somatic mutations have been identified as prognostic markers in CLL. On a cohort of 110 patients with CLL treated with first-line fludarabin, cyclophosphamide, and rituximab treatment compared with 33 untreated (watch and wait) patients with CLL, we report more frequent complex karyotypes (34 vs 15%; P = .05), unmutated IGHV (70 vs 21%; P karyotyping therefore appears to be of value, CK being an additional factor, undetectable in classical FISH, in patients with CLL at the stage when therapy becomes required.

  1. Overweight but unseen: a review of the underestimation of weight status and a visual normalization theory.

    Science.gov (United States)

    Robinson, E

    2017-10-01

    Although overweight and obesity are widespread across most of the developed world, a considerable body of research has now accumulated, which suggests that adiposity often goes undetected. A substantial proportion of individuals with overweight or obesity do not identify they are overweight, and large numbers of parents of children with overweight or obesity fail to identify their child as being overweight. Lay people and medical practitioners are also now poor at identifying overweight and obesity in others. A visual normalization theory of the under-detection of overweight and obesity is proposed. This theory is based on the notion that weight status is judged relative to visual body size norms. Because larger body sizes are now common, this has caused a recalibration to the range of body sizes that are perceived as being 'normal' and increased the visual threshold for what constitutes 'overweight'. Evidence is reviewed that indicates this process has played a significant role in the under-detection of overweight and obesity. The public health relevance of the under-detection of overweight and obesity is also discussed. © 2017 The Authors. Obesity Reviews published by John Wiley & Sons Ltd on behalf of World Obesity.

    Full Text Available Abstract Background The clinical benefits associated with targeted oncology agents are generally limited to subsets of patients. Even with favorable biomarker profiles, many patients do not respond or acquire resistance. Existing technologies are ineffective for treatment monitoring as they provide only static and limited information and require substantial amounts of tissue. Therefore, there is an urgent need to develop methods that can profile potential therapeutic targets with limited clinical specimens during the course of treatment. Methods We have developed a novel proteomics-based assay, Collaborative Enzyme Enhanced Reactive-immunoassay (CEER that can be used for analyzing clinical samples. CEER utilizes the formation of unique immuno-complex between capture-antibodies and two additional detector-Abs on a microarray surface. One of the detector-Abs is conjugated to glucose oxidase (GO, and the other is conjugated to Horse Radish Peroxidase (HRP. Target detection requires the presence of both detector-Abs because the enzyme channeling event between GO and HRP will not occur unless both Abs are in close proximity. Results CEER was able to detect single-cell level expression and phosphorylation of human epidermal growth factor receptor 2 (HER2 and human epidermal growth factor receptor 1 (HER1 in breast cancer (BCa systems. The shift in phosphorylation profiles of receptor tyrosine kinases (RTKs and other signal transduction proteins upon differential ligand stimulation further demonstrated extreme assay specificity in a multiplexed array format. HER2 analysis by CEER in 227 BCa tissues showed superior accuracy when compared to the outcome from immunohistochemistry (IHC (83% vs. 96%. A significant incidence of HER2 status alteration with recurrent disease was observed via circulating tumor cell (CTC analysis, suggesting an evolving and dynamic disease progression. HER2-positive CTCs were found in 41% (7/17 while CTCs with significant HER2

    to review the social determinants of health more characteristic of the child and adolescents of immigrants, by reviewing the literature and assess its effect on nutritional status. a systematic review was performed using Medical Subject Headings (MeSH) in PubMed (Medline) and The Cochrane Library, in order to identify undetected studies; articles bibliographic lists were examined. The final election was done according to inclusion and exclusion criteria. No restrictions on sex and ethnicity of the participants. STROBE checkpoints were used for an information and methodological quality control. As Social Determinants of Health (SDH); social, demographic and economic conditions were considered for the study of their effect on the nutritional status. from 31 identified articles 18 are included in this study, 17 (94.4%) had a good or excellent quality. Hispanic and African were the most studied ethnicities; birth place and parent's residence period were used for generational classification. Alimentary culture and linguistic isolation of the first generation have a protective effect preventing from overweight and obesity risk while it decrease in second and third generation due to the experienced acculturation process equalizing their weight gain to natives; which prevalence is higher among Hispanics. No relation was found for nutritional status differences between sexes neither alimentary aids protective effect hypothesis was confirmed. the SDH with greater influence on child-adolescent immigrants were the socio-demographic conditions; among them: residence period distinguish the three identified generations while linguistic barrier and ethnic background are truly influential on the biological response to the experimented change caused by the acculturation process, establishing differences in the nutritional status.

    Status epilepticus (SE) is a frequent neurological emergency complicated by high mortality and often poor functional outcome in survivors. The aim of this study was to review available clinical scores to predict outcome. Literature review. PubMed Search terms were "score", "outcome", and "status epilepticus" (April 9th 2015). Publications with abstracts available in English, no other language restrictions, or any restrictions concerning investigated patients were included. Two scores were identified: "Status Epilepticus Severity Score--STESS" and "Epidemiology based Mortality score in SE--EMSE". A comprehensive comparison of test parameters concerning performance, options, and limitations was performed. Epidemiology based Mortality score in SE allows detailed individualization of risk factors and is significantly superior to STESS in a retrospective explorative study. In particular, EMSE is very good at detection of good and bad outcome, whereas STESS detecting bad outcome is limited by a ceiling effect and uncertainty of correct cutoff value. Epidemiology based Mortality score in SE can be adapted to different regions in the world and to advances in medicine, as new data emerge. In addition, we designed a reporting standard for status epilepticus to enhance acquisition and communication of outcome relevant data. A data acquisition sheet used from patient admission in emergency room, from the EEG lab to intensive care unit, is provided for optimized data collection. Status Epilepticus Severity Score is easy to perform and predicts bad outcome, but has a low predictive value for good outcomes. Epidemiology based Mortality score in SE is superior to STESS in predicting good or bad outcome but needs marginally more time to perform. Epidemiology based Mortality score in SE may prove very useful for risk stratification in interventional studies and is recommended for individual outcome prediction. Prospective validation in different cohorts is needed for EMSE, whereas

  8. Relationships between Psychosocial Resilience and Physical Health Status of Western Australian Urban Aboriginal Youth.

    Directory of Open Access Journals (Sweden)

    Katrina D Hopkins

    Full Text Available Psychosocial processes are implicated as mediators of racial/ethnic health disparities via dysregulation of physiological responses to stress. Our aim was to investigate the extent to which factors previously documented as buffering the impact of high-risk family environments on Aboriginal youths' psychosocial functioning were similarly beneficial for their physical health status.We examined the relationship between psychosocial resilience and physical health of urban Aboriginal youth (12-17 years, n = 677 drawn from a representative survey of Western Australian Aboriginal children and their families. A composite variable of psychosocial resilient status, derived by cross-classifying youth by high/low family risk exposure and normal/abnormal psychosocial functioning, resulted in four groups- Resilient, Less Resilient, Expected Good and Vulnerable. Separate logistic regression modeling for high and low risk exposed youth revealed that Resilient youth were significantly more likely to have lower self-reported asthma symptoms (OR 3.48, p<.001 and carer reported lifetime health problems (OR 1.76, p<.04 than Less Resilient youth.The findings are consistent with biopsychosocial models and provide a more nuanced understanding of the patterns of risks, resources and adaptation that impact on the physical health of Aboriginal youth. The results support the posited biological pathways between chronic stress and physical health, and identify the protective role of social connections impacting not only psychosocial function but also physical health. Using a resilience framework may identify potent protective factors otherwise undetected in aggregated analyses, offering important insights to augment general public health prevention strategies.

    Full Text Available BACKGROUND Diabetic neuropathy, retinopathy and nephropathy are the chronic complications of diabetes mellitus. Neuropathy, retinopathy and nephropathy are microvascular complication of diabetes mellitus. Antioxidant status is reduced in DM-induced retinopathy and nephropathy. Present study is undertaken to evaluate the degree of oxidative stress in diabetic neuropathy patients. The aim of the study is to study on oxidative stress as measured by lipid peroxidation marker, malondialdehyde and antienzyme status in type II DM patients with neuropathy and compared them with a controlled nondiabetic group. MATERIALS AND METHODS The study included 100 subjects from Sapthagiri Medical College, Bangalore, from January 1, 2015, to December 31, 2015, of age group 50 to 70 yrs. out of which 50 patients were non-insulin-dependent DM with neuropathy and rest 50 age and sex matched apparently healthy individuals (control group. Antioxidant status was assessed by measuring superoxide dismutase (SOD, glutathione peroxidase (GPx, glutathione reductase (GR, Catalase and Reduced Glutathione (GSH. RESULTS It showed a significant increase p<0.001 in FBS, PPBS, TC, TG, LDL, VLDL, CAT, MDA, while HDL, GSH, GPX, GR and SOD were found to be decreased significantly (p 0.001. CONCLUSION MDA was significantly elevated in diabetic group, whereas antioxidant enzymes superoxide dismutase, glutathione peroxidase, glutathione reductase and reduced glutathione were significantly decreased, which might be helpful in risk assessment of various complications of DM. The data suggests that alteration in antioxidant status and MDA may help to predict the risk of diabetic neuropathy.

    2015-11-01

    We examine a key modified labeling theory proposition-that a psychiatric label increases vulnerability to competence-based criticism and rejection-within task- and collectively oriented dyads comprised of same-sex individuals with equivalent education. Drawing on empirical work that approximates these conditions, we expect the proposition to hold only among men. We also expect education, operationalized with college class standing, to moderate the effects of gender by reducing men's and increasing women's criticism and rejection. But, we also expect the effect of education to weaken when men work with a psychiatric patient. As predicted, men reject suggestions from teammates with a psychiatric history more frequently than they reject suggestions from other teammates, while women's resistance to influence is unaffected by their teammate's psychiatric status. Men also rate psychiatric patient teammates as less powerful but no lower in status than other teammates, while women's teammate assessments are unaffected by their teammate's psychiatric status. Also as predicted, education reduces men's resistance to influence when their teammate has no psychiatric history. Education also increases men's ratings of their teammate's power, as predicted, but has no effect on women's resistance to influence or teammate ratings. We discuss the implications of these findings for the modified labeling theory of mental illness and status characteristics theory. Copyright © 2015 Elsevier Inc. All rights reserved.

    Over the past four decades, paralleling the increasing prevalence of childhood obesity, the share of families with only one child has been rising steadily. Using three waves of the National Survey of Children's Health, we examine the effect of being the only child in a family on childhood obesity and the mechanisms through which singleton status might affect childhood obesity. We find gender-specific and age-dependent singleton effects. That is, singletons have a higher level of body mass ind...

    1990-01-01

    Concepts are investigated for an automated status and control system for a distributed processing environment. System characteristics, data requirements for health assessment, data acquisition methods, system diagnosis methods and control methods were investigated in an attempt to determine the high-level requirements for a system which can be used to assess the health of a distributed processing system and implement control procedures to maintain an accepted level of health for the system. A potential concept for automated status and control includes the use of expert system techniques to assess the health of the system, detect and diagnose faults, and initiate or recommend actions to correct the faults. Therefore, this research included the investigation of methods by which expert systems were developed for real-time environments and distributed systems. The focus is on the features required by real-time expert systems and the tools available to develop real-time expert systems.

    The contribution is intended as a status report, assessing current digital radiography from the angle of view of the year 1983, placing emphasis on digital imaging with the image enhancement and television equipment, discussing the luminescent foil technique in great detail. The article deals with the interpretation of the term resolution, necessary in connection with the digital technique, as well as with the possibility offered by the digital technique, to change standards for pulsed fluoroscopic, or stereo operation. The article explains the advantages of real-time image processing as against fluoroscopic operation. The control methods of digital radiography also are digital, as are the communication systems between the various system components (generators, central unit). The prospects of this imaging method are estimated in an extrpolation of the current status. (orig./MG) [de

    Full Text Available Background: Heart rate variability (HRV had been promoted for longer than half a century to monitor the activity of autonomic nerve systems. Previous studies have not clarified the relationship between HRV and prehypertension (pre-HTN status compared with the normal group. We aimed to figure out the optimal model or cutoff point for predicting the possible pre-HTN status. Patients and Methods: We retrospectively collected and reviewed 2586 Asian people who had joined annual physical examination in Tri-Service General Hospital at 2013. The patient profiles such as age, gender, body height, body weight, body weight index, waist circumferences, and serological biochemistry data were analyzed and correlated with HRV parameter. Results: A total number of 909 patients were enrolled in our study. The physical stress index (PSI owed a small but most significant Spearman's relation coefficient (r = 0.118, P58.4. Early intervention to these participants may decrease cardiovascular events in the coming future.

    Full Text Available Due to its encouaring results, classic homeopathy soon became very popular that a great number of homeopathic hospitals and educational institutions in Europe and America were founded at the end of the 19th century. However, historic events at the beinning of the 20th century diminished its use for the longer period of time. Since 1970, homoeopathy has been reviving in many countries of the world in different domains – educational institutions have appeared, it has been incorporated in many national health systems and there has been research development. Nowadays, homeopathy is recognised in all continents either as an independent or alternative (complementary medical system. Since status of homeopathy and possibilities for education have not been uniformed and standardized in the world, the aim of this article is to offer an abbreviated review on possibilities of education, status and history of homeopathy.

    We present the current status of a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor), consisting of a 4-stage X-ray telescope and an array of TES microcalorimeters, cooled with mechanical coolers, with a total weight of about 400 kg. The mission will perform survey observations of warm-hot intergalactic medium using OVII and OVIII emission lines, with the energy coverage up to 1.5 keV. The wide field of view of about 50' diameter, superior energy resolution close to 2 eV FWHM, and very low background will together enable us a wide range of science for diffuse X-ray sources. We briefly describe the current status of the development of the satellite, and the subsystems.

  2. Photoprotection and vitamin D status.

    2010-11-03

    The adverse effects of solar ultraviolet radiation on the skin are well documented, especially in fair-skinned people. These can be ameliorated by photoprotection strategies advocated by many public health bodies and typically include sun avoidance, sunscreen use and clothing. The UVB waveband which is the main cause of all adverse effects investigated in the laboratory to date is also the waveband for vitamin D photosynthesis which is the only established benefit of solar exposure. This is especially important because solar UVB is the main source of vitamin D for most people. There is increasing evidence that vitamin D plays a much greater role in human health than was previously thought. This has given rise to concerns that photoprotection, especially sunscreen use, could adversely affect vitamin D status and human health. Furthermore, it is stated that people with heavily pigmented skins often have poor vitamin D status because of photoprotection by melanin. In this paper we review the effect of photoprotection strategies and pigmentation on vitamin D status. Clothing can clearly be very effective at inhibiting vitamin D synthesis. Sunscreens are effective in theory and some limited human studies support this. However, most studies show little or no effect and the most likely reason for this is that sunscreens have not been applied in the manner that was used to determine their labelled index of protection against sunburn. This could change in the future if public health campaigns and the sunscreen industry are successful in encouraging the public to apply sunscreens more liberally and/or use much higher levels of labelled protection. The role of melanin on vitamin D status is not clear and requires further investigation. Copyright © 2010. Published by Elsevier B.V.

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

  10. Marital status, health and mortality.

    2012-12-01

    Marital status and living arrangements, along with changes in these in mid-life and older ages, have implications for an individual's health and mortality. Literature on health and mortality by marital status has consistently identified that unmarried individuals generally report poorer health and have a higher mortality risk than their married counterparts, with men being particularly affected in this respect. With evidence of increasing changes in partnership and living arrangements in older ages, with rising divorce amongst younger cohorts offsetting the lower risk of widowhood, it is important to consider the implications of such changes for health in later life. Within research which has examined changes in marital status and living arrangements in later life a key distinction has been between work using cross-sectional data and that which has used longitudinal data. In this context, two key debates have been the focus of research; firstly, research pointing to a possible selection of less healthy individuals into singlehood, separation or divorce, while the second debate relates to the extent to which an individual's transitions earlier in the life course in terms of marital status and living arrangements have a differential impact on their health and mortality compared with transitions over shorter time periods. After reviewing the relevant literature, this paper argues that in order to fully account for changes in living arrangements as a determinant of health and mortality transitions, future research will increasingly need to consider a longer perspective and take into account transitions in living arrangements throughout an individual's life course rather than simply focussing at one stage of the life course.

    The specific age to which an HIV infected child can be disclosed to is stipulated to begin between ages 4 and 6 years. It has also been documented that before disclosure of HIV positive status to the infected child. Health care providers should consider children's cognitive-developmental ability. However, observation and situation analysis show that, health care providers still feel uncomfortable disclosing the HIV positive status to the infected child. The aim of the study was to explore healthcare providers' experiences in disclosure of HIV-positive status to the infected child. A qualitative study involving 20 health care providers who attend HIV-positive children was conducted in September, 2014 in Dar es Salaam, Tanzania. Participants were selected from ten HIV care and treatment clinics (CTC) by purposive sampling. An interview guide, translated into participants' national language (Kiswahili) was used during in-depth interviews. Sampling followed the principle of data saturation. The interviews focused on perspectives of health-care providers regarding their experience with paediatric HIV disclosure. Data from in-depth interviews were transcribed into text; data analysis followed qualitative content analysis. The results show how complex the process of disclosure to children living with HIV can be to healthcare providers. Confusion was noted among healthcare providers about their role and responsibility in the process of disclosing to the HIV infected child. This was reported to be largely due to unclear guidelines and lack of standardized training in paediatric HIV disclosure. Furthermore, healthcare providers were concerned about parental hesitancy to disclose early to the child due to lack of disclosure skills and fear of stigma. In order to improve the disclosure process in HIV infected children, healthcare providers recommended further standardized training on paediatric HIV disclosure with more emphasis on practical skills and inclusion of disclosure

Subjects of both genders (n=40) diagnosed with mild to moderate Alzheimer's disease according to NINCDS-ADRDA criteria, participated in the study. Socioeconomic status, activities of daily life, anthropometric, clinical and dietary profiles were surveyed. Of the total, 65% were female. More than 70% were capable of accomplishing daily activities by themselves. Subjects were eutrophic with a statistically significant difference of the arm circumference between the mild and moderate groups. As for illnesses secondary to Alzheimer's, 52% of the elderly presented hypertension, followed by arthrosis type alterations (17%). The mean consumption of energy and macronutrients in the elderly classified as mild dementia was of 1645 kcal, distributed in 53.7% of carbohydrate, 17.5% of proteins or 0.9 g/kg and 28.8% of lipids. For those classified as moderate dementia it was of 1482 kcal, distributed in 59.3% of carbohydrate, 16.1% of proteins and 24.6% of lipids. In this descriptive study of elderly outpatients with mild and moderate Alzheimer's disease, most presented a nutritional status of eutrophy, with adequate dietary intake of carbohydrates, proteins, lipids and vitamin C, but with low dietary intake of vitamin E.

    Renewable energy markets, industries, and policy frameworks have evolved rapidly in recent years. The Renewables Global Status Report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by many contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecasts. This latest Renewables Global Status Report saw: a shift in investment patterns that led to a global decrease in clean energy investment; continuing growth in installed capacity due to significant technology cost reductions and increased investment in developing countries; renewables progressively supplementing established electricity systems, demonstrating that the implementation of suitable policies can enable the successful integration of higher shares of variable renewables; and the emergence of integrated policy approaches that link energy efficiency measures with the implementation of renewable energy technologies.

  18. Status and the evaluation of workplace deviance.

    Bowles, Hannah Riley; Gelfand, Michele

    2010-01-01

    Bias in the evaluation of workplace misbehavior is hotly debated in courts and corporations, but it has received little empirical attention. Classic sociological literature suggests that deviance by lower-status actors will be evaluated more harshly than deviance by higher-status actors. However, more recent psychological literature suggests that discrimination in the evaluation of misbehavior may be moderated by the relative status of the evaluator because status influences both rule observance and attitudes toward social hierarchy. In Study 1, the psychological experience of higher status decreased rule observance and increased preferences for social hierarchy, as we theorized. In three subsequent experiments, we tested the hypothesis that higher-status evaluators would be more discriminating in their evaluations of workplace misbehavior, evaluating fellow higher-status deviants more leniently than lower-status deviants. Results supported the hypothesized interactive effect of evaluator status and target status on the evaluation of workplace deviance, when both achieved status characteristics (Studies 2a and 2b) and ascribed status characteristics (i.e., race and gender in Study 3) were manipulated.

    Monitoring acaricide resistance in field ticks and use of suitable managemental practices are essential for controlling tick populations infesting animals. In the present study, the acaricide resistance status in Rhipicephalus (Boophilus) microplus ticks infesting cattle and buffaloes of five districts located in the eastern Indian state, Bihar were characterized using three data sets (AIT, Biochemical assays and gene sequences). Adult immersion test (AIT) was adopted using seven field isolates and their resistance factor (RF) was determined. Six isolates (DNP, MUZ, BEG, VSH, DRB and SUL) were found resistant to both deltamethrin and diazinon and except VSH all were resistant to cypermethrin. One isolate (PTN) was susceptible with a RF below 1.5. To understand the possible mode of resistance development, targeted enzymes and gene sequences of the para sodium channel and achetylcholinesterase 2 (AChE2) were analyzed. The esterase, monooxygenase and glutathione-S-transferase (GST) activity of reference susceptible IVRI-I line was determined as 2.47 ± 0.007 nmol/min/mg protein, 0.089 ± 0.0016 nmol/mg of protein and 0.0439 ± 0.0003 nmol/mg/min respectively, which increased significantly in the resistant field isolates. However, except esterases, the fold increase of monooxygenase (1.14-2.27 times) and GST (0.82-1.53 times) activities were not very high. A cytosine (C) to adenine (A) nucleotide substitution (CTC to ATC) at position 190 in domain II S4-5 linker region was detected only in one isolate (SUL) having RF of 34.9 and in the reference deltamethrin resistant line (IVRI-IV). However, the T2134A mutation was not detected in domain IIIS6 transmembrane segment of resistant isolates and also in reference IVRI-IV line despite of varying degree of resistance. The flumethrin specific G215T and the recently identified T170C mutations were also absent in domain II sequences under study.

    The aim of the study was to assess whether pill burden is associated with self-reported adherence to current combination antiretroviral regimens and health status in a large sample of unselected and chronically treated HIV-infected patients. An adherence and health status questionnaire was offered to all patients collecting their drugs between March and May 2010 at our clinic; both parameters were primarily evaluated using a visual analogue scale. Linear correlations were evaluated using Spearman's correlation coefficient. Wilcoxon's rank-sum test and the χ(2) test were used to compare quantitative and qualitative variables. The generalized linear model was used in multivariable analyses. Among 2763 subjects on treatment during the study period, 2114 (78.8% male; mean age 46.9 ± 8.84 years) were tested for adherence; 1803 (85.3%) had viral loads pill burden and dosing interval, adherence was higher in patients with undetectable HIV RNA (P pill burden (P = 0.019). In this highly adherent population, the number of daily pills was related to self-reported health status but not to self-reported adherence, whereas the dosing interval did not influence self-reported adherence or health status. © 2012 British HIV Association.

    Chronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as 'metabolic syndrome', may play a negative role on the overall survival of liver transplant patients. In this report we review

    There has long been speculation that nominal Anastrepha fraterculus comprises more than a single biological species. Herein is a review of data supporting the hypothesis that multiple cryptic species are present. Evidence includes unusual variation in pest status, morphology, karyotypes, isozymes, mitochondrial DNA and cuticular hydrocarbon. The data strongly support the notion of multiple cryptic species. However, it is not yet possible to state how many species may be involved or to delineate them by diagnostic morphology, distribution, host plants or behavior. A combination of methodologies will be needed to resolve the complex. (author)

    1994-07-01

    Selected health status data for elderly populations from similar industrial cities-Youngstown, Ohio, USA, and Debrecen, Hungary-were compared. Because of their impoverished health care system, unregulated heavily industrialized society, and unhealthful life-styles Hungarians were hypothesized to have poorer health status than Americans, even after taking into account demographic mediating factors. The study provides a health status baseline for elderly Hungarians shortly after communism's fall in 1989-1990 and shows how great a gap exists between Hungarian health status and that in the West. Hungarians were in much poorer health as measured by functional status, symptomatology, medical condition, depression, and subjective health status. Distinctions persisted when controlling for gender, age, and education. Poverty-level (and income) did not explain health status differences. The paper concludes that Hungary should pay more attention to health promotion, prevention, and primary care, as well as to reforming patient management in hospitals, nursing homes, and home care programs.

    The U.S. Armed Forces offer educational and training benefits as incentives for service. This study investigates the influence of status configurations on military enlistment and their link to greater educational opportunity. Three statuses (socioeconomic status of origin, cognitive ability and academic performance) have particular relevance for life course options. We hypothesize that young men with inconsistent statuses are more likely to enlist than men with consistent status profiles, and that military service improves access to college for certain configurations. Analyses of the National Longitudinal Study of Adolescent Health (Add Health) show (1. that several status configurations markedly increased the likelihood of military enlistment and (2. within status configurations, recruits were generally more likely to enroll in higher education than nonveterans, with associate degrees being more likely.

    The paper describes the status of repository development for the different waste categories. Low and Intermediate Waste Disposal facility of El Cabril was commissioned in 1992 and is in normal operation. The major modifications and activities during the last years are the adaptation to waste streams not initially foreseen such as some decommissioning waste or waste from steel industry, and the improvement of its performance assessment, supported by a R and D and refined models. As part of this facility, a new disposal facility specifically intended for very low activity waste has been constructed and commissioned in July 2008. Its design is based on the European Directive for hazardous waste disposal. National policy for Nuclear Spent Fuel and High-Level waste is focused on the development of a centralized storage facility of the vault type, whose site location would be selected through a volunteering process. Meanwhile, with the aim of solving specific problems, three individual storage facilities are in different status at reactor sites. Research on final solution, including some repository aspects as well as separation and transmutation are being carried out in accordance to ENRESA's R and D program. ENRESA has developed conceptual designs for non site specific repositories, both in granite and clay, and has carried out their corresponding performance assessment exercises. (authors)

    2015-04-01

    Functional status assessment has been recommended as a part of a complete nutrition assessment for decades, but the specific components of this assessment have eluded a consensus definition. The recent Academy of Nutrition and Dietetics/American Society for Parenteral and Enteral Nutrition consensus criteria for identification of malnutrition include functional assessment determined by handgrip dynamometry, with the understanding that this technique is not practical for use in some patient populations. Other techniques for functional assessment include physical performance measures such as timed gait and chair stands, as well as activities of daily living tools such as the Katz Index, Lawton Scale, and Karnofsky Scale Index. Manual muscle testing and computed tomography scan assessment of lean tissue are other tools that show promise in correlating functional and nutrition assessments. Functional assessment parameters may be least well correlated with nutrition status in older individuals. Despite a number of scientific studies of a variety of tools for functional assessment, there is to date no definitive tool for use in all individuals in all settings. Nutrition scientists and clinicians must continue to collaborate with colleagues in physical and occupational therapy, geriatrics, and nursing to refine current functional assessment tools to more effectively correlate with nutrition and malnutrition assessment parameters. © 2015 American Society for Parenteral and Enteral Nutrition.

    Full Text Available The Compressed Baryonic Matter (CBM experiment at the Facility for Anti-Proton and Ion Research (FAIR will explore the phase diagram of strongly interacting matter at highest net baryon densities and moderate temperatures. The CBM physics program will be started with beams delivered by the SIS 100 synchrotron, providing energies from 2 to 11 GeV/nucleon for heavy nuclei, up to 14 GeV/nucleon for light nuclei, and 29 GeV for protons. The highest net baryon densities will be explored with ion beams up to 45 GeV/nucleon energy delivered by SIS 300 in the next stage of FAIR. Collision rates up to 107 per second are required to produce very rare probes with unprecedented statistics in this energy range. Their signatures are complex. These conditions call for detector systems designed to meet the extreme requirements in terms of rate capability, momentum and spatial resolution, and a novel DAQ and trigger concept which is not limited by latency but by throughput. The article discusses the development status of the CBM sub-systems for charged particle tracking, vertex detection, electron/muon identification, hadron/time-of-flight measurement, electromagnetic and zero-degree calorimetry, in terms of prototypes and expected physics performance. The concept and development status of CBM’s central detector, the Silicon Tracking System STS are presented in somewhat more detail.

  8. Vegetarian diets and bone status.

    Tucker, Katherine L

    2014-07-01

    Osteoporosis is a common chronic condition associated with progressive loss of bone mineral density (BMD) and compromised bone strength, with increasing risk of fracture over time. Vegetarian diets have been shown to contain lower amounts of calcium, vitamin D, vitamin B-12, protein, and n-3 (ω-3) fatty acids, all of which have important roles in maintaining bone health. Although zinc intakes are not necessarily lower quantitatively, they are considerably less bioavailable in vegetarian diets, which suggests the need for even higher intakes to maintain adequate status. At the same time, healthy vegetarian diets tend to contain more of several protective nutrients, including magnesium, potassium, vitamin K, and antioxidant and anti-inflammatory phytonutrients. On balance, there is evidence that vegetarians, and particularly vegans, may be at greater risk of lower BMD and fracture. Attention to potential shortfall nutrients through the careful selection of foods or fortified foods or the use of supplements can help ensure healthy bone status to reduce fracture risk in individuals who adhere to vegetarian diets. © 2014 American Society for Nutrition.

    Organophosphorus(OP) poisoning, in addition to its cholinergic manifestations shows metabolic derangements leading to hyperglycemia. Apart from inhibiting acetylcholinesterase it also induces oxidative stress to exhibit this manifestation. The present study aims to assess the glycemic status of OP poisoned patients and its association with various factors in OP poisoning like oxidative stress and dose of atropine. This is a prospective study which recruited 102 patients above 18 years of age with history of OP poisoning. They were categorized into 3 grades-mild, moderate and severe based on the Peradeniya Organophosphorus Poisining Scale. The routine biochemical parameters along with serum malondialdehyde (MDA) and cholinesterase were estimated in the study group. Hyperglycemia and glycosuria were observed, with majority cases of hyperglycemia (57%) noticed in the severe group. There was a rise in the random plasma glucose (RPG), serum malondialdehyde (MDA), total dose of atropine across the groups along with a fall in the serum cholinesterase with increase in severity of poisoning. The fall in plasma glucose at the time of discharge was significant in all three groups when compared to the admission random plasma glucose(RPG) level. This transient hyperglycemia exhibited a significant positive association with serum MDA and dose of atropine administered during treatment (p<0.05). Glycemic status in OP poisoning may play a role in identifying the severity of poisoning at the time of admission.

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2011. The report covers both current status and key trends; by design, it does not provide analysis or forecast the future. Global energy consumption rebounded in 2010 after an overall downturn in 2009. Renewable energy, which experienced no downturn in 2009, continued to grow strongly in all end-use sectors - power, heat and transport - and supplied an estimated 16% of global final energy consumption. Renewable energy accounted for approximately half of the estimated 194 gigawatts (GW) of new electric capacity added globally during the year. Renewables delivered close to 20% of global electricity supply in 2010, and by early 2011 they comprised one quarter of global power capacity from all sources. In several countries, renewables represent a rapidly growing share of total energy supply, including heat and transport

    Full Text Available The objective of this study was to compare the periodontal status in postmenopausal women with osteopenia and osteoporosis. Material and Methods: We examined 43 postmenopausal women aged from 55 to 74 years. Material assessment of bones in every patient was performed by means of dual energy X-ray absorptiometry (DXA from two points on the skeleton – part of the femur neck and between the first and fourth lumbar vertebrae. A lipid blood test was done for patients of both groups. All patients were divided into two groups (the 1st with osteopenia, and the 2nd with osteoporosis. All patients were subjected to an oral clinical examination: the periodontal examination was composed of Plaque Index (PI, Pocket Score (PS, and Papillary Bleeding Index (PBI. X-ray analysis was performed for every patient. Results: The results of the clinical periodontal examination demonstrated that the mean PBI in patients in the 1st group had no significant differences from the PBI in patients in the 2nd group. PI value and PS findings in patients with general osteoporosis also had no statistical differences from the same parameters in patients with osteopenia. Conclusion: Under the circumstances of these patients’ characteristics and within the limits of the present study, we concluded that there is no significant difference in the periodontal status of postmenopausal women with systemic osteopenia and with osteoporosis.

    Full Text Available Objectives: The purpose of this study was to assess the occlusal status in schoolchildren in Yemen, and to compare the results with those of other studies. Materials and Methods: The sample for this epidemiological survey consisted of 3003 primary school students, half of whom were boys and the other half girls, aged 12 years. The subjects were randomly selected, and none had received previous orthodontic treatment. Variables examined included intra-arch irregularities and malalignment (crowding and spacing in the incisal segments of the arch and midline diastema and discrepancies in occlusal contact relationship (maxillary overjet, mandibular overjet, anterior openbite and antero-posterior molar relation. Results: The results showed that about 26.1% of the subjects were still in the late mixed dentition stage and 73.9% presented with a dentition in the early permanent stage. Normal overjet was found in 55% of the sample. Crowding was observed in 31.4% of the subjects and midline diastema in 14.2%. Conclusion: Occlusal status among Yemeni children was characterized by a relatively high frequency of dental crowding, as well as a relatively high frequency of anterior mandibular overjet (Class III malocclusions.

Current studies corroborate associations between low SSS and poor health indicators by extending previous findings to further populations and biological risk factors, providing meta-analytic evidence for adolescents and by demonstrating that negative affect may not confound associations between SSS and self-rated health. Recent findings also highlight the relevance of SSS changes (e.g. SSS loss in immigrants) and the need to consider cultural/ethnical differences in psychological mediators and associations between SSS and health. SSS is a comprehensive measure of one's social position that is related to several poor health outcomes and risk factors for disease. Future investigation, particularly prospective studies, should extend research on SSS and health to further countries/ethnic groups, also considering additional psychological and biological mediators and dynamic aspects of SSS. Recently developed experimental approaches to manipulate SSS may also be promising.

    In the new report, Energy Status NVE provides a unified presentation of statistics and facts about the Norwegian energy system. It gives an overview of the production, transmission and consumption of electricity in the Norwegian society, and shows energy use for various purposes and the relationship between energy and the environment. Norway is the sixth largest hydropower producer in the world and, together with Iceland the highest portion of renewable electricity production of all countries in Europe. In comparison, is about 17 percent of all electricity in the EU based on renewable resources. In Sweden, renewable energy resources account for about half of all electricity production, while the corresponding share in Denmark is about 29 percent. The good supply of water power has contributed to the fact that Norway has a consumption pattern that differs from the countries around us. (AG)

    2007-07-01

    Rising expectations best characterize the current prospects of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns and growing environmental pressures. It appears that the inherent economic and environmental benefits of the technology and its excellent performance record over the last twenty years are beginning to tilt the balance of political opinion and public acceptance in favour of nuclear power. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a substantial contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power may be headed in the short-to-medium run (20 to 40 years from now). (auth)

    In today's regulatory and financial environment, improving plant efficiency and safety are necessary elements of plant operations. Public utility commissions are making rate rulings based, in part, on plant availability performance; and the NRC is putting more emphasis on plant operational aspects. This comes at a time when operating, maintaining, and managing a plant are becoming increasingly complex; moreover, the desired number of experienced plant personnel are becoming more difficult to find. This situation can be partially resolved by using computer software tools to assist operations, maintenance, engineering, and management personnel. These software tools provide information and interpretations based on plant and equipment status. They support improved plant availability, technical specification compliance, and administrative functions. A key element or computerization is the ability to operate on integrated information

    The Majorana Collaboration is constructing the Majorana Demonstrator, an ultra-low background, 40-kg modular high purity Ge detector array to search for neutrinoless double-beta decay in 76Ge. In view of the next generation of tonne-scale Ge-based neutrinoless double-beta decay searches that will probe the neutrino mass scale in the inverted hierarchy region, a major goal of the Demonstrator is to demonstrate a path forward to achieving a background rate at or below 1 count/tonne/year in the 4 keV region of interest around the Q-value at 2039 keV. The current status of the Demonstrator is discussed, as are plans for its completion.

  5. Maternal folate status and lactation.

    Folate plays an essential role in DNA, RNA, and protein biosynthesis. For this reason, the physiological need for this vitamin is increased during periods of rapid anabolic activity such as pregnancy and lactation. Although the importance of folate and the consequences of suboptimal folate status during pregnancy, especially during the periconceptional period, are well appreciated, little is known about the value of folate during lactation. The limited number of studies available on folate intake during lactation suggest that many women do not consume an adequate amount of folate and that recommended target intakes may be too low. Although inadequate maternal folate intake does not affect milk folate concentration unless maternal deficiency is severe, potential consequences of suboptimal folate nutrition to both the mother and her future offspring should also be considered.

  6. Status report on radionuclide transfer

    International Nuclear Information System (INIS)

    1980-01-01

    At the suggestion of the Federal Minstry of the Interior, in June 1978, a group of scientists from several institutions who are active in the field of radionuclide transfer or are interested in these problems got together. During the discussions of the work team, especially the transfer soil/plants was emphasized. Then the work team set up a status report on the transfer of the radionuclides relevant in the sense of the radiation protection act. The nuclides H 3 and C14, the isotopes of the Sr, J, and Cs, Tc99, the so-called corrosion nuclides Mn54, Fe59, co-isotopes and Zn65, and isotopes of Pu, Am, and Cm were regarded as important for a possible radiation exposition. Recent investigations revealed that also the natural radionuclides Ra226, Po210, and Pb210 should be covered by the investigations. The goal of this status report is to present the level of knowledge on the transfer of these radionuclides to man in a brief form, giving hints at the most important literature. It was requested by the Federal Ministry of the Interior, as fas as possible, to indicate transfer factors which are necessary for the radio-occology act to be decreed according to Para. 45 of the radiation protection act. Another goal of the report was to show the gap in the knowledge on the radio nuclide transfer. This was thought to help to create a basis for the decisions of the Federal Ministry concerning the support of other investigation projects in the field of transfer of radionuclides. (orig./MG) [de

    The DIRAC Project was initiated to provide a data processing system for the LHCb Experiment at CERN. It provides all the necessary functionality and performance to satisfy the current and projected future requirements of the LHCb Computing Model. A considerable restructuring of the DIRAC software was undertaken in order to turn it into a general purpose framework for building distributed computing systems that can be used by various user communities in High Energy Physics and other scientific application domains. The CLIC and ILC-SID detector projects started to use DIRAC for their data production system. The Belle Collaboration at KEK, Japan, has adopted the Computing Model based on the DIRAC system for its second phase starting in 2015. The CTA Collaboration uses DIRAC for the data analysis tasks. A large number of other experiments are starting to use DIRAC or are evaluating this solution for their data processing tasks. DIRAC services are included as part of the production infrastructure of the GISELA Latin America grid. Similar services are provided for the users of the France-Grilles and IBERGrid National Grid Initiatives in France and Spain respectively. The new communities using DIRAC started to provide important contributions to its functionality. Among recent additions can be mentioned the support of the Amazon EC2 computing resources as well as other Cloud management systems; a versatile File Replica Catalog with File Metadata capabilities; support for running MPI jobs in the pilot based Workload Management System. Integration with existing application Web Portals, like WS-PGRADE, is demonstrated. In this paper we will describe the current status of the DIRAC Project, recent developments of its framework and functionality as well as the status of the rapidly evolving community of the DIRAC users.

    Hypothesizing that nutritional status, systemic inflammation and tumoral immune microenvironment play a role as determinants of lung cancer evolution, the purpose of this study was to assess their respective impact on long-term survival in resected non-small cell lung cancers (NSCLC). Clinical, pathological and laboratory data of 303 patients surgically treated for NSCLC were retrospectively analyzed. C-reactive protein (CRP) and prealbumin levels were recorded, and tumoral infiltration by CD8+ lymphocytes and mature dendritic cells was assessed. We observed that factors related to nutritional status, systemic inflammation and tumoral immune microenvironment were correlated; significant correlations were also found between these factors and other relevant clinical-pathological parameters. With respect to outcome, at univariate analysis we found statistically significant associations between survival and the following variables: Karnofsky index, American Society of Anesthesiologists (ASA) class, CRP levels, prealbumin concentrations, extent of resection, pathologic stage, pT and pN parameters, presence of vascular emboli, and tumoral infiltration by either CD8+ lymphocytes or mature dendritic cells and, among adenocarcinoma type, tumor grade (all pnutrition and tumoral immune microenvironment allowed robust prognostic discrimination; indeed patients with undetectable CRP, high (>285 mg/L) prealbumin levels and high (>96/mm2) CD8+ cell count had a 5-year survival rate of 80% [60.9-91.1] as compared to 18% [7.9-35.6] in patients with an opposite pattern of values. When stages I-II were considered alone, the prognostic significance of these factors was even more pronounced. Our data show that nutrition, systemic inflammation and tumoral immune contexture are prognostic determinants that, taken together, may predict outcome.

    The aim of this study was to evaluate the usefulness of computer-aided detection (CAD) in diagnosing early colorectal cancer using computed tomography colonography (CTC). A total of 30 CTC data sets for 30 early colorectal cancers in 30 patients were retrospectively reviewed by three radiologists. After primary evaluation, a second reading was performed using CAD findings. The readers evaluated each colorectal segment for the presence or absence of colorectal cancer using five confidence rating levels. To compare the assessment results, the sensitivity and specificity with and without CAD were calculated on the basis of the confidence rating, and differences in these variables were analyzed by receiver operating characteristic (ROC) analysis. The average sensitivities for the detection without and with CAD for the three readers were 81.6% and 75.6%, respectively. Among the three readers, only one reader improved sensitivity with CAD compared to that without. CAD decreased specificity in all three readers. CAD detected 100% of protruding lesions but only 69.2% of flat lesions. On ROC analysis, the diagnostic performance of all three readers was decreased by use of CAD. Currently available CAD with CTC does not improve diagnostic performance for detecting early colorectal cancer. An improved CAD algorithm is required for detecting fiat lesions and reducing the false-positive rate. (author)

    To assess the micronutrient status and its relationship with nutritional status in preschool children. In a cross sectional study, anthropometric data and fasting blood samples were obtained from 340 children attending preschool in urban Sri Lanka. Serum concentrations of vitamin D, parathyroid hormone, vitamin A, zinc and haemoglobin were measured. Z-scores of anthropometric indices of height-for-age, weight-for-age and weight-for-height were computed to evaluate the nutritional status. Prevalence of stunting, underweight, wasting and anaemia among children were 7.1%, 16.9%, 21.2% and 7.4%, respectively. Deficiencies of zinc and vitamin A occurred among 67% and 38% of children, respectively. Vitamin D deficiency (Nutritional status was significantly correlated (pnutritional status of the children was related to vitamin D status and with haemoglobin status. Zinc and vitamin A levels were low in children with severe stunting. Vitamins A, D and zinc levels were associated with haemoglobin status.

    The Outreach Project was initiated in October 1994 with the objective of developing a multi-year plan for the U.S. Department of Energy (DOE) for targeted outreach activities for stakeholders in industry and the general public. This status report summarizes the work on industry outreach that has been completed since the inception of the project in October 1994. A three-pronged approach was taken to ascertain issues related to industry outreach. First, there was a review of on-going and past industry outreach activities at DOE and NHA. Next, a series of meetings with industry decision makers was arranged to get a better understanding of industry interests and concerns, and to discuss how DOE and industry could work collaboratively to develop hydrogen energy systems. Third, a workshop is scheduled where representatives from industry, DOE and other federal agencies can identify issues that would enhance partnering between the federal government and industry in the development of hydrogen energy systems. At this tiny, the review of on-going and past activities has been completed. Industry interviews are in progress and a majority of meetings have been held. Analysis of the information gained is in progress. The preliminary analysis of this information indicates that for appropriate near-term demonstration-type projects, the level of interest for collaboration between DOE and industry is high. The data also identifies issues industry is concerned with which impact the commercialization of hydrogen energy systems.

    CUORE is a cryogenic detector consisting of 988 TeO2 crystals, 750 g each, and will be operated at a temperature of ˜10 mK, to search for neutrinoless double beta decay (0νββ) of 130Te. The detector, in the final stages of construction at the Laboratori Nazionali del Gran Sasso (Italy), will start its operations in 2016. CUORE-0, its pilot experiment, has proven the feasibility of CUORE, demonstrating that the target background of 0.01 counts/keV/kg/y and the energy resolution of 5 keV are within reach. CUORE-0 also made the most precise measurement of the 2νββ decay. The expected sensitivity of CUORE to the 0νββ 130Te half-life is 9 ·1025y, for 5 years of data taking. Here, we report the most recent results of CUORE-0, their implications for CUORE, and the current status of the CUORE experiment.

  18. Current status of nuclear power

    International Nuclear Information System (INIS)

    Behnke, W.B.

    1984-01-01

    The decision to devote the 1984 conference to nuclear power is timely and appropriate. Illinois has a long, and distinguished history in the development of civilian nuclear power. The concept was born at the University of Chicago, developed at Argonne National Laboratory and demonstrated on the Commonwealth Edison system at our pioneer Dresden Nuclear Station. Today, Illinois ranks number one in the nation in nuclear generation. With over a quarter century of commercial operating experience, nuclear power has proven its worth and become a significant and growing component of electric power supply domestically and throughout the world. Despite its initial acceptance, however, the nuclear power industry in the U.S. is now in the midst of a difficult period of readjustment stemming largely from the economic and regulatory problems of the past decade. As a result, the costs of plants under construction have increased dramatically, causing serious financial difficulties for several projects and their owners. At the same time, the U.S. is facing hard choices concerning its future energy supplies. Conferences such as this have an important role in clarifying the issues and helping to find solutions to today's pressing energy problems. This paper summarizes the status of nuclear power both here and abroad, discussing the implications of current events in the context of national energy policy and economic development here in Illinois

    Sleep electrical status epilepticus (SESE) is a rare entity whose diagnosis depends or showing spike and wave complexes on the EEG during more than 85% of the duration of NoREM sleep. Typically it presents in children, most of whom have subjacent epilepsy. It is currently accepted that SESE is asymptomatic, although its persistence may give rise to severe neuropsychological sequelae. There are no references to sleep disorders in these patients. We present the case of a seven year old girl with SESE, hypersomnia and secondary nocturnal enuresis. The seven year old patient had a past history of simple partial crises with motor symptoms. There was progressive hypersomnia and nocturnal enuresis. The polysomnogram showed SESE. The Test for Multiple Latencies in Sleep (TMLS) showed pathological diurnal somnolence. HLA DR2 typing was negative. Neuropsychological study showed severe alterations in the language area, with a normal intelligence quotient. The new findings presented suggested that SESE is an intrinsic sleep disorder and not merely an EEG pattern. Since it occurs in children, sometimes with neuropsychological deficits, systematic TMLS should be done. The association of hypersomnia, changes in immediate visual memory and autistic regression suggest involvement of the limbic system.

    There is interest in age-related cognitive decline and environmental risk factors for Alzheimer's disease (AD). This interest is focused on individual differences in exposure to agents that may harm or protect cognitive function. Caffeine is used as a short acting mental stimulant and may possess longer-term properties that protect against age-related decline and, possibly, AD. The current study aimed to: 1) examine current cognitive function in a narrow age range sample (n=351) without dementia (MMSE>25) who are, by reason of age, entering the period of increased risk of AD; and 2) link cognitive function to self-reported intake of caffeine and socioeconomic status (SES). Possible confounding by gender, childhood intelligence, education, and symptoms of anxiety and depression was introduced into the statistical model. There were significant differences between SES groups in caffeine intake (pcaffeine intake were associated with slower digit symbol speed (F =3.38, pcaffeine during cognitive testing and strong links between SES and cognitive performance. No evidence in support of cognitive enhancing effects of caffeine was found.

    Uranium exploration in Brazil was started in 1952 by the Brazilian National Research Council. This led to the discovery of the first uranium deposits in Pocos de Caldas and Jacobina. These activities was later continued by the National Energy Commission/Comissao Nacional de Energia Nuclear (CNEN), formed in 1962. The founding of NUCLEBRAS at the end of 1974 marked the increasing effort of the country's uranium exploration programme. At this time only the Pocos de Caldas deposit was known with measurable resources. Due to the reorganization of the Brazilian nuclear programme in 1988, all uranium exploration in the country was stopped. By then, eight areas with uranium reserves has been identified. Brazil uranium resources in the RAR category at ≤ $80/kg U cost range are estimated to be 162,000 tonnes U, out of which 56,100 tonnes are in the ≤ $40/kg U cost range. Additional resources in the EAR-I category and the cost range ≤ 80/kg U are in the order of 100,200 tonnes U. The first production of uranium in Brazil, at the Osamu Utsumi mine (Pocos de Caldas deposit), started in 1982. Because of escalated costs and reduced demand, this activity was put on stand-by status between 1990 and 1992. The mine was restarted in 1993, but was stopped again in October 1995. The cumulative production of the mine to 1996 was 1241 tonnes U. The Lagoa Real deposit is currently being prepared as a new producing mine. (author)

    The RENO (Reactor Experiment for Neutrino Oscillation) is under construction to measure the value of the smallest and unknown neutrino mixing angle θ 13 . The experiment will compare the measured fluxes of electron antineutrinos at two detectors located at 290 m and 1.4 km distances from the center of the Yonggwang nuclear reactors in Korea, with world-second largest thermal power output of 16.4 GW. Construction of experimental halls and access tunnels for both near and far detector sites was completed in early 2009. The detectors are near completion, and data-taking is planned to start in mid 2010. An expected number of observed antineutrino is roughly 510 and 80 per day in the near detector and far detector, respectively. An estimated systematic uncertainty associated with the measurement is less than 0.6%, and an expected statistical error is about 0.3%. With three years of data, the experiment will search for the mixing angle values of sin 2 (2θ 13 ) down to 0.02 in 90% C.L. limit. In this talk, the construction status will be presented. (author)

  3. MARS Validation Plan and Status

    The KINS Reactor Thermal-hydraulic Analysis System (KINS-RETAS) under development is directed toward a realistic analysis approach of best-estimate (BE) codes and realistic assumptions. In this system, MARS is pivoted to provide the BE Thermal-Hydraulic (T-H) response in core and reactor coolant system to various operational transients and accidental conditions. As required for other BE codes, the qualification is essential to ensure reliable and reasonable accuracy for a targeted MARS application. Validation is a key element of the code qualification, and determines the capability of a computer code in predicting the major phenomena expected to occur. The MARS validation was made by its developer KAERI, on basic premise that its backbone code RELAP5/MOD3.2 is well qualified against analytical solutions, test or operational data. A screening was made to select the test data for MARS validation; some models transplanted from RELAP5, if already validated and found to be acceptable, were screened out from assessment. It seems to be reasonable, but does not demonstrate whether code adequacy complies with the software QA guidelines. Especially there may be much difficulty in validating the life-cycle products such as code updates or modifications. This paper presents the plan for MARS validation, and the current implementation status

    ARGOS is the Laser Guide Star and Wavefront sensing facility for the Large Binocular Telescope. With first laser light on sky in 2013, the system is currently undergoing commissioning at the telescope. We present the overall status and design, as well as first results on sky. Aiming for a wide field ground layer correction, ARGOS is designed as a multi- Rayleigh beacon adaptive optics system. A total of six powerful pulsed lasers are creating the laser guide stars in constellations above each of the LBTs primary mirrors. With a range gated detection in the wavefront sensors, and the adaptive correction by the deformable secondary's, we expect ARGOS to enhance the image quality over a large range of seeing conditions. With the two wide field imaging and spectroscopic instruments LUCI1 and LUCI2 as receivers, a wide range of scientific programs will benefit from ARGOS. With an increased resolution, higher encircled energy, both imaging and MOS spectroscopy will be boosted in signal to noise by a large amount. Apart from the wide field correction ARGOS delivers in its ground layer mode, we already foresee the implementation of a hybrid Sodium with Rayleigh beacon combination for a diffraction limited AO performance.

    Renewable energy markets and policy frameworks have evolved rapidly in recent years. This report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by a network of more than 400 contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecast the future. As such, this report and subsequent editions will serve as a benchmark for measuring global progress in the deployment of renewable energy, which is of particular interest in this International Year of Sustainable Energy for All. UN Secretary-General Ban Ki-moon has marked the occasion with a new global initiative, Sustainable Energy for All, which seeks to mobilise global action on three inter-linked objectives to be achieved by 2030: universal access to modern energy services, improved rates of energy efficiency, and expanded use of renewable energy sources

  6. Aging, Nutritional Status and Health

    Directory of Open Access Journals (Sweden)

    Full Text Available The older population is increasing worldwide and in many countries older people will outnumber younger people in the near future. This projected growth in the older population has the potential to place significant burdens on healthcare and support services. Meeting the diet and nutrition needs of older people is therefore crucial for the maintenance of health, functional independence and quality of life. While many older adults remain healthy and eat well those in poorer health may experience difficulties in meeting their nutritional needs. Malnutrition, encompassing both under and over nutrition increases health risks in the older population. More recently the increase in obesity, and in turn the incidence of chronic disease in older adults, now justifies weight management interventions in obese older adults. This growing population group is becoming increasingly diverse in their nutritional requirements. Micro-nutrient status may fluctuate and shortfalls in vitamin D, iron and a number of other nutrients are relatively common and can impact on well-being and quality of life. Aging presents a number of challenges for the maintenance of good nutritional health in older adults.

    The problems posed and the challenges offered by QFD, at this time, are analyzed and discussed. A convenient starting point is afforded by a comparison of the different circumstances of QFD and QCD. Some features of the conventional methodology of QFD, which may be deemed to be questionable, are underlined. The prospects of the standard model are examined in the light of recent experiments, and some theoretical deficiencies of the model are noted. Following a brief comment about the status of some recently proposed models, it is suggested that one search for new physical principles which may be governing the structure of weak interactions in a hitherto unperceived way. Manifest left-right symmetry and time-reversal invariance, realized as symmetries of the Nambu-Goldstone type, are mentioned as possible examples of such principles; additional motiviation for these symmetries emerges in a discussion of recent work on the problem of natural suppression of strong T-violation. The report concludes with a brief appraisal of the present state of QFD

    This report describes the findings of a review undertaken on behalf of the project management group of the programme 'Endlagersicherheit in der Nachbetriebsphase' based at GSF-IfT (Forschungszentrum fuer Umwelt und Gesundheit - Institut fuer Tieflagerung) to establish the current status of research into the simulation of geochemical processes relevant to radiological assessment. The review is intended to contribute to Stage 1 of a strategy formulated to enhance the use of geochemical models in Germany. Emphasis has been placed on processes deemed to be of greatest relevance to performance assessment for a HLW-repository in a salt dome principally, speciation-solubility in high salinity solutions, complexation by natural organics and generation-transport of colloids. For each of these and other topics covered, a summary is given of fundamental concepts, theoretical representations and their limitations, highlighting, where appropriate, the advantages and disadvantages of alternative approaches. The availability of data to quantify any given representation is addressed, taking into account the need for information at elevated temperatures and pressures. Mass transfer is considered in terms of aqueous, particulate and gas-mediated transport, respectively. (orig.) [de

    The environment and climate has in recent years received their deserved place high on the public agenda. Still many important issues and contexts make little or no attention in the debates. As environmental directorates one of the most important tasks is to contribute reliable, relevant and understandable information about the state of the environment and development. Environmental status 2009 provides a thematic and comprehensive overview of environmental challenges in Norway. Where are we today, and what are the biggest challenges ahead? What are the national goals? And what have we achieved? The information is based on facts and analysis from their own work and from various research and knowledge communities co-working with the directorate.Climate change has been given much space because it is the biggest threat to the environment. Loss of biological diversity - a major problem compounded by climate change - and the fight against environmental toxins that affect animal and human health, are also high priority. Directorate for Nature Management and Norwegian Pollution Control Authority are responsible for the report and the contents of the chapters on biodiversity and pollution. The chapter on cultural heritage is written by the Cultural Heritage. (AG)

    Following the formation of United Reprocessors (U.R.G.) in 1976 by British Nuclear Fuels Limited (B.N.F.L.) in the United Kingdom, the Commissariat a l'Energie Atomique (C.E.A.) in France and K.E.W.A. Kernbrennstoff-Wiederaufarbeitungs-Gesellschaft MBH (K.E.W.A.) in Germany, collaboration is now well established for the marketing of their reprocessing services for irradiated oxide fuel from thermal reactors. In addition collaboration in the continued evolution of the technology has progressed and an extensive research and development programme has been established, the results of which are exchanged between the shareholders. During 1976 the U.K. Government has given approval to B.N.F.L. to sign further contracts with foreign customers, subject to certain conditions. In France, the fuel cycle activities of the C.E.A. have been vested in a new company (Compagnie Generale Des Matieres Nucleaires (C.O.G.E.M.A.)) and their La Hague plant has commenced reprocessing operations on irradiated oxide fuel. In Germany, an agreement has been signed between K.E.W.A. and P.W.K. for the pre-project study for the proposed German plant. Against this background this paper reviews the present status of reprocessing by the shareholders of U.R.G. and the prospects for reprocessing

  12. Vitamin D Status in Korea

    Full Text Available The majority of the vitamin D in our body is produced by cutaneous synthesis in response to sunlight. As more and more people live in cities and spend the bulk of their time indoors, it can be difficult to get sufficient sun exposure for adequate cutaneous production of vitamin D. Therefore, vitamin D insufficiency has become a very common health problem worldwide. The Korea National Health and Nutrition Examination Survey IV 2008 showed that the prevalence of vitamin D insufficiency, defined as a serum 25-hydroxyvitamin D [25(OHD] level below 50 nmol/L, was 47.3% in males and 64.5% in females. Only 13.2% of males and 6.7% of females had a serum 25(OHD level of greater than 75 nmol/L. In Korea, vitamin D insufficiency was more prevalent in young adults than in elderly people, likely due to the indoor lifestyle of younger people. Compared with the United States and Canada, Korea has a lower mean 25(OHD level and a higher prevalence of vitamin D insufficiency. To improve the vitamin D status of the Korean population, more aggressive policies on food fortification and vitamin D supplementation are needed.

  13. Robotic renal transplantation: Current status

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Introduction: Kidney transplantation (KT has traditionally been performed by open renal transplantation, but recently, a few groups including our own have described a minimally invasive approach to KT. We aim to discuss the current status of robotic kidney transplantation (RKT and describe our technique of RKT with regional hypothermia. Material and Methods: We used the search terms "minimally invasive" OR "robotic" OR "robot assisted" AND "kidney transplantation." Papers written in English and concerning technical and/or clinical outcomes following minimally invasive kidney transplantation were selected. Three hundred and eighteen unique articles were retrieved and nine were relevant. Comparative outcomes data following RKT with regional hypothermia versus open KT (OKT from our own group were also included. Findings: Nine papers, so far, have evaluated the role of robotic approach in KT and have conclusively established the feasibility, safety, and reproducibility of RKT, although these studies have been performed by experienced robotic surgeons/teams. The contemporary published series note that rejection rates were similar in RKT and OKT patients. Mean serum creatinine at 6 months in RKT and OKT patients was equivalent, across the three series. Most of the studies also note a dramatic reduction in the wound-related complication rates. Conclusion: RKT appears to be a safe surgical alternative to the standard open approach of KT. RKT is associated with reduced postoperative pain, analgesic requirement, and better cosmesis. RKT, although in its infancy, appears to be associated with lower complication rates.

    This literature work is mainly focusing on the mechanisms of modern converter steelmaking and related with the evaluation of converter technology applied during the last decades and further to the future. The history of steelmaking has been briefly reviewed from bloomeries and early-steelmaking processes to the progress of modern converter process. The pneumatic converter processes were developed in the 1850`s and thereafter the basis for the rapid growth of steel industries was established for the next 100 years. The world production of steel has not continuously grown but fluctuating quite much. It reached 723 Mt in 1994. The production is believed to grow the forecast for the year 2003 being approximately 800 Mt. Electric arc furnace production is estimated to reach 280 Mt by 2003, and BOFIOH will reach 520 Mt by 2003. The current status of the converter steelmaking process is briefly described both on its theoretical bases and practical technological progresses. Developments which significantly improve the process are briefly discussed. Several more recent developments such as combined oxygen blowing process, increased scrap melting, post combustion and hot metal pretreatment are discussed. The future progress will be in further development of these process characteristics as well as in eventual emerging of the continuous converter process. (author)

  15. Monitor for status epilepticus seizures

    Johnson, Mark; Simkins, Thomas

    1994-01-01

    This paper describes the sensor technology and associated electronics of a monitor designed to detect the onset of a seizure disorder called status epilepticus. It is a condition that affects approximately 3-5 percent of those individuals suffering from epilepsy. This form of epilepsy does not follow the typical cycle of start-peak-end. The convulsions continue until medically interrupted and are life threatening. The mortality rate is high without prompt medical treatment at a suitable facility. The paper describes the details of a monitor design that provides an inexpensive solution to the needs of those responsible for the care of individuals afflicted with this disorder. The monitor has been designed as a cooperative research and development effort involving the United States Army Armament Research, Development, and Engineering Center's Benet Laboratories (Benet) and the Cerebral Palsy Center for the Disabled (Center), in association with the Department of Neurology at Albany Medical College (AMC). Benet has delivered a working prototype of the device for field testing, in collaboration with Albany Medical College. The Center has identified several children in need of special monitoring and has agreed to pursue commercialization of the device.

    Pediatric Status Epilepticus (SE) is an emergency situation with high morbidity and mortality that requires early and aggressive management. The minimum time criterion to define SE was reduced from 30 to 5 minutes, defined as continuous seizure activity or rapidly recurrent seizures without resumption of consciousness for more than 5 minutes. This definition considers that seizures that persist for > 5 minutes are likely to do so for more than 30 min. Those that persist for more than 30 minutes are more difficult to treat. Refractory SE is the condition that extends beyond 60-120 minutes and requires anesthetic management. Super-refractory SE is the state of no response to anesthetic management or relapse during withdrawal of these drugs. The aim of this review is to provide and update on convulsive SE concepts, pathophysiology, etiology, available antiepileptic treatment and propose a rational management scheme. A literature search of articles published between January 1993 and January 2013, focused on pediatric population was performed. The evidence about management in children is limited, mostly corresponds to case series of patients grouped by diagnosis, mainly adults. These publications show treatment alternatives such as immunotherapy, ketogenic diet, surgery and hypothermia. A 35% mortality, 26% of neurological sequelae and 35% of recovery to baseline condition is described on patient’s evolution.

    The Wide-Field InfraRed Survey Telescope (WFIRST) will be the next Astrophysics flagship mission to follow JWST. The observatory payload consists of a Hubble-size telescope aperture with a wide-field NIR instrument and a coronagraph operating at visible wavelengths and employing state-of-the-art wavefront sensing and control. The Wide-field instrument is optimized for large area NIR imaging and spectroscopic surveys, with performance requirements driven by programs to study cosmology and exoplanet detection via gravitational microlensing. All data will be public immediately, and a substantial guest observer program will be supported.The WFIRST Project is presently in Phase A, with a transition to Phase B expected in early to mid 2018. Candidate observing programs are under detailed study in order to inform the mission design, but the actual science investigations will not be selected until much closer to launch. We will present an overview of the present mission design and expected performance, a summary of Project status, and plans for selecting the observing programs.

    Materialism influences many people. We focus on two aspects of this influence: reactions to prestige products and to the influence of others. A study of 187 U.S. student consumers shows that materialism is positively related to buying products that confer status. In contrast, materialism is negatively related to consumer independence, an enduring tendency to pay minimal attention to the prescribed norms of other consumers and to make product and brand decisions according to personal preferences. Consuming products for status is also negatively related to consumer independence. Moreover, the association between materialism and consumer independence is completely mediated by consuming for status. Materialism urges consumers to be status conscious so that they follow social norms in purchasing, but seeking status through goods is avoided by less materialistic, independent consumers. A second study (n = 258) also using student consumers confirmed these results.

  16. Altered mental status from acyclovir.

    Martinez-Diaz, Gabriel J; Hsia, Renee

    2011-07-01

    Acyclovir is widely used in the treatment of herpes virus infections, particularly herpes simplex virus and varicella-zoster virus. Acyclovir, when given promptly upon the start of a herpes zoster eruption, speeds healing and diminishes acute pain. Because acyclovir is a commonly used medication, it is crucial for health providers to be aware of appropriate dosing as well as possible side effects. We present this case to increase awareness of the potential for inappropriate dosing of acyclovir and the presentations of patients with toxic effects. We report the case of a 65-year-old man with a past medical history significant for chronic kidney disease who presented to the Emergency Department with progressive confusion and ataxia over 2 days. Thorough questioning in the patient's native language revealed that he had recently started a medication for a "rash." Neither he nor his family knew the name of the new medication; further investigation revealed it to be acyclovir. Although other diagnoses were considered in the differential diagnosis for this patient with altered mental status, he was treated for presumed acyclovir toxicity and given prompt dialysis, upon which his symptoms resolved. It is important for physicians to remember that even common medications such as acyclovir can have serious side effects and complications. In this case, renal dosing was not used in a patient on hemodialysis. Acyclovir must be renally dosed and carefully monitored through drug level measurement in patients with limited kidney function to prevent serious side effects, such as the neurological sequelae demonstrated in this case report. Emergency physicians should be aware of the potential for inappropriate dosing of this medication and the presentations of patients with toxic effects. Copyright © 2011 Elsevier Inc.

    As we approach the 22nm half-pitch (hp) technology node, the industry is rapidly running out of patterning options. Of the several lithography techniques highlighted in the International Technology Roadmap for Semiconductors (ITRS), the leading contender for the 22nm hp insertion is extreme ultraviolet lithography (EUVL). Despite recent advances with EUV resist and improvements in source power, achieving defect free EUV mask blank and enabling the EUV mask infrastructure still remain critical issues. To meet the desired EUV high volume manufacturing (HVM) insertion target date of 2013, these obstacles must be resolved on a timely bases. Many of the EUV mask related challenges remain in the pre-competitive stage and a collaborative industry based consortia, such as SEMATECH can play an important role to enable the EUVL landscape. SEMATECH based in Albany, NY is an international consortium representing several of the largest manufacturers in the semiconductor market. Full members include Intel, Samsung, AMD, IBM, Panasonic, HP, TI, UMC, CNSE (College of Nanoscience and Engineering), and Fuller Road Management. Within the SEMATECH lithography division a major thrust is centered on enabling the EUVL ecosystem from mask development, EUV resist development and addressing EUV manufacturability concerns. An important area of focus for the SEMATECH mask program has been the Mask Blank Development Center (MBDC). At the MBDC key issues in EUV blank development such as defect reduction and inspection capabilities are actively pursued together with research partners, key suppliers and member companies. In addition the mask program continues a successful track record of working with the mask community to manage and fund critical mask tools programs. This paper will highlight recent status of mask projects and longer term strategic direction at the MBDC. It is important that mask technology be ready to support pilot line development HVM by 2013. In several areas progress has been

    The twin satellites of the Gravity Recovery and Climate Experiment (GRACE) were launched on March 17, 2002 and have operated for nearly 16 years. The mission objectives are to observe the spatial and temporal variations of the Earth's mass through its effects on the gravity field at the GRACE satellite altitude. The mass changes observed are related to both the changes within the solid earth and the change within and between the Erath system components. A significant cause of the time varying mass is water motion and the GRACE mission has provided a continuous decade long measurement sequence which characterizes the seasonal cycle of mass transport between the oceans, land, cryosphere and atmosphere; its inter-annual variability; and the climate driven secular, or long period, mass transport signals. The fifth reanalysis on the mission data set, the RL05 data, were released in mid-2013. With the planned launch of GRACE Follow-On in early 2018, plans are underway for a reanalysis that will be consistent with the GRACE FO processing standards. The mission is entering the final phases of its operation life with mission end expected to occur in early 2018. The current mission operations strategy emphasizes extending the mission lifetime to obtain an overlap with the GRACE FO. This presentation will review the mission status and the projections for mission lifetime, describe the current operations philosophy and its impact on the science data, discuss the issues related to achieving the GRACE and GRACE FO connection and discuss issues related to science data products during this phase of the mission period.

  19. Primary status, complementary status, and organizational survival in the U.S. venture capital industry.

    2015-07-01

    We introduce a distinction between two kinds of status and examine their effects on the exit rates of organizations investing in the U.S. venture capital industry. Extending past work on status-based competition, we start with a simple baseline: we describe primary status as a network-related signal of an organization's quality in a leadership role, that is, as a function of the degree to which an organization leads others that are themselves well regarded as lead organizations in the context of investment syndicates. Combining Harary's (1959) image of the elite consultant with Goffman's (1956) concept of "capacity-esteem," we then discuss complementary status as an affiliation-based signal of an organization's quality in a supporting role. We measure complementary status as a function of the extent to which an organization is invited into syndicates by well-regarded lead organizations-that is, by those possessing high levels of primary status. Findings show that, conditioning on primary status, complementary status reduces the rate at which venture capital organizations exit the industry. Consistent with the premise that these kinds of status correspond to different roles and market identities, we also find that complementary status attenuates (and ultimately reverses) the otherwise favorable effect of primary status on an organization's life chances. Theoretically and methodologically oriented scope conditions, as well as implications for future research, are discussed. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-01-01

    Full Text Available Aim of the present work was evaluation of factors affecting interregional variability of the human selenium status.Discussion. Essentiality of selenium to human beings determines the priority of the selenium status evaluation in different regions of the world. At the same time interregional variability of the human selenium status biomarkers are often underestimated. Among factors affecting the human selenium status geochemical characteristic of soils and anthropogenic influence are proved to be the most significant. The importance of seas and oceans are emphasized as important sources of the element. Examples of great interregional variability of the human selenium status are indicated and the importance of complex approach for evaluation of ecological risks connected with inadequate selenium consumption are emphasized. Such an approach should combine the data of selenium distribution in soils, levels of selenium bio concentration by different plants species, selenium content in water, food products and in human biological fluids and tissues. Difficulties in the human selenium status optimization are shown to be typical in regions with significant geochemical variations and intensive anthropogenic loading.Conclusions. High interregional variability of the human selenium status determines the necessity of complex approach in revealing ecological risks connected with selenium deficiency of excess in the environment both in regions with high utilization of local food products and in large industrial regions and towns and also in conditions of separate specific industrial production. 

  1. Hierarchy and social status in Budongo chimpanzees.

    Science.gov (United States)

    Newton-Fisher, Nicholas E

    2004-04-01

    The status hierarchy is fundamental in the lives of male chimpanzees. This study describes the dominance interactions and social status among adult male chimpanzees of the Sonso community in the Budongo Forest Reserve, Uganda, during the period that they were first studied (1994 and 1995). Social dominance is typically measured using the behaviour of either the subordinate or the dominant individual, but a relationship is dependent on the behaviour of both parties and this study explicitly used both subordinate and dominant behaviours to investigate the status hierarchy. Among adult males of the Sonso community, agonistic interactions occurred at a low rate and pant-grunts were rare, but males could be ranked into separate hierarchies of agonistic dominance and pant-grunting (labelled 'respect') using ratios of behaviour performed/behaviour received. These hierarchies were combined to form a single hierarchy of social status that divided the males among five distinct status levels. The highest status level was held by an alliance between two males who replaced the previous alpha male during the first part of the study. Neither male in this alliance partnership pant-grunted to the other, although the reason for cooperative behaviour was unclear. Although the nominally beta male was treated as such by other adult males, he achieved surprisingly little mating success. Budongo Forest chimpanzees do not warrant the sometimes-expressed view that they are non-aggressive and peaceable and the broad pattern of their status interactions matches with that seen in other chimpanzee populations.

    Nutritional status is a major clinical parameter in multiple cancers. Indeed, nutritional status is a prognostic factor and a predictor of response and toxicity to treatments in breast and lung cancers for instance. To our knowledge, in patients suffering from malignant primary brain tumors, nutritional status has been poorly investigated. Nutritional status of 26 glioblastoma patients relapsing after a first line of treatment was studied. The body mass index (BMI), the prognostic inflammatory and nutritional index (PINI) and the instant nutritional score (INS) were assessed. The BMI was abnormal in 12 patients, two were malnourished while 10 were overweight. The BMI was not correlated to age of patients. Overweight status did not impact patient survival but it was associated with reduced performance status. The PINI was abnormal in three patients. Finally, the INS was abnormal in 24 patients, noted 2 (n=22) or 4 (n=4). Our results were not in favor of systematic nutritional support in patients with recurrent glioblastoma after a first line of treatment. Being overweight does not influence prognosis but may influence performance status. Steroid therapy and chemotherapy (inducing sodium and water retention and lymphopenia) weaken the relevance of BMI and INS for nutritional assessment in patients with recurrent glioblastoma. Further studies using additional nutritional tests in larger, independent and prospective cohorts of patients are warranted to obtain more details. Copyright © 2013 Elsevier Masson SAS.

  3. Decoupling social status and status certainty effects on health in macaques: a network approach

    2016-09-01

    Full Text Available Background Although a wealth of literature points to the importance of social factors on health, a detailed understanding of the complex interplay between social and biological systems is lacking. Social status is one aspect of social life that is made up of multiple structural (humans: income, education; animals: mating system, dominance rank and relational components (perceived social status, dominance interactions. In a nonhuman primate model we use novel network techniques to decouple two components of social status, dominance rank (a commonly used measure of social status in animal models and dominance certainty (the relative certainty vs. ambiguity of an individual’s status, allowing for a more complex examination of how social status impacts health. Methods Behavioral observations were conducted on three outdoor captive groups of rhesus macaques (N = 252 subjects. Subjects’ general physical health (diarrhea was assessed twice weekly, and blood was drawn once to assess biomarkers of inflammation (interleukin-6 (IL-6, tumor necrosis factor-alpha (TNF-α, and C-reactive protein (CRP. Results Dominance rank alone did not fully account for the complex way that social status exerted its effect on health. Instead, dominance certainty modified the impact of rank on biomarkers of inflammation. Specifically, high-ranked animals with more ambiguous status relationships had higher levels of inflammation than low-ranked animals, whereas little effect of rank was seen for animals with more certain status relationships. The impact of status on physical health was more straightforward: individuals with more ambiguous status relationships had more frequent diarrhea; there was marginal evidence that high-ranked animals had less frequent diarrhea. Discussion Social status has a complex and multi-faceted impact on individual health. Our work suggests an important role of uncertainty in one’s social status in status-health research.

    During the past decade, zirconia-based ceramics have been successfully introduced into the clinic to fabricate fixed dental prostheses (FDPs), along with a dental computer-aided/computer-aided manufacturing (CAD/CAM) system. In this article (1) development of dental ceramics, (2) the current status of dental CAD/CAM systems, (3) CAD/CAM and zirconia restoration, (4) bond between zirconia and veneering ceramics, (5) bond of zirconia with resin-based luting agents, (6) surface finish of zirconia restoration and antagonist enamel wear, and (7) clinical evaluation of zirconia restoration are reviewed. Yttria partially stabilized tetragonal zirconia polycrystalline (Y-TZP) showed better mechanical properties and superior resistance to fracture than other conventional dental ceramics. Furthermore, ceria-stabilized tetragonal zirconia polycrystalline and alumina nanocomposites (Ce-TZP/A) had the highest fracture toughness and had resistance to low-temperature aging degradation. Both zirconia-based ceramics have been clinically available as an alternative to the metal framework for fixed dental prostheses (FDPs). Marginal adaptation of zirconia-based FDPs is acceptable for clinical application. The most frequent clinical complication with zirconia-based FDPs was chipping of the veneering porcelain that was affected by many factors. The mechanism for the bonding between zirconia and veneering ceramics remains unknown. There was no clear evidence of chemical bonding and the bond strength between zirconia and porcelain was lower than that between metal and porcelain. There were two alternatives proposed that might avoid chipping of veneering porcelains. One was hybrid-structured FDPs comprising CAD/CAM-fabricated porcelain parts adhering to a CAD/CAM fabricated zirconia framework. Another option was full-contour zirconia FDPs using high translucent zirconia. Combined application of silica coating and/or silane coupler, and 10-methacryloyloxydecyl dihydrogen phosphate is

  7. NPAR program - Status and accomplishments

    1991-01-01

    Upon completing the early scoping studies, the US NRC Office of Nuclear Regulatory Research took a lead worldwide in 1985 by publishing a comprehensive program plan for Nuclear Plant aging Research (NPAR). The plan identified significant technical safety issues related to plant aging; discussed a phased approach to aging and life assessment of components systems, and structures; and recommended the utilization of research results for, (i) the selection and the prioritization of components and structures, (ii) where to focus inspection and maintenance, (iii) what type of data collection and record keeping would be useful, (iv) how to perform technical evaluation of mothballed units for reactivation, (v) the determination of risk significance of aging, (vi) the development of technical bases for license renewal and extended plant life considerations, (vii) the ongoing regulatory issues, and (viii) recommendations to the national codes and standards groups involved in activities related to aging. Since the publication of the NPAR program plan in 1985 significant progress has been made in completing the initial phase of the NPAR activities and substantial new initiatives have been undertaken expanding the overall scope. Also, by recognizing the NRC's leadership role for emphasizing the need for aging management significant developments are taking place worldwide in implementing dedicated programs related to understanding and managing aging in older operating nuclear power plants. In fact, in some countries, aging management programs are being implemented now for relatively new plants so as to eventually realize the potential benefits of extended plant life beyond the originally conceived design and service life. This paper briefly describe the major elements of the NPAR program, its status and results or accomplishments. In the process the author emphasizes the need for total industry commitment and participation in implementing programs for understanding and managing

    Lang, C; von Stockert, T R

    1986-04-01

    Aphasia therapy in adults has been established to a larger extent relatively lately in the history of aphasiology, i.e. after its social medical importance had been realized and one of the cardinal problems of neurology solved more satisfactorily--lesion localization by imaging techniques. In order to evaluate the efficiency of aphasia therapy--which is still not quite uncontradicted--it was necessary to acquire sufficient knowledge of the spontaneous recovery process. It takes place--e.g. after stroke--mainly during the first 3 months, coming, as a rule, to a halt during the first year. Longer recovery periods, however, have been described. Next to etiology neurological status, overall health condition, type and severity of aphasia, and time delay between onset of the disease and start of therapy have been ascertained, whereas age and handedness seem to be of minor relevance. If syndrome change occurs the boundary between Broca's and Wernicke's aphasia is not surpassed; this taken apart almost any change from a more severe to a milder form of aphasia is possible. To isolate the therapeutic effect from spontaneous recovery in larger groups is difficult. There are, however, more recent investigations which suggest, that a correctly indicated therapy, which is sufficiently intensive and lasts long enough, will be effective. One of the corner-stones of any therapeutic effort ist adequate stimulation, oriented toward the patients needs and his aphasic syndrome, and taking into account the systemic nature of language and its most important linguistic structural components. Furthermore, a phase-specific and interdisciplinary approach and integration of closely related persons play an important role. We divide the numerous therapeutic techniques into 3 groups: direct or stimulation approach, indirect or circumventory approach, compensatory or alternative strategies approach. Representatives of all 3 groups are presented briefly, e.g. auditory stimulation, divergent

  9. The current status of radiosurgery

    Objectives: Review the role of radiosurgery in recurrent malignant gliomas for palliative purposes. Review the role of radiosurgery in newly diagnosed malignant glioma as boost therapy and emphasize the randomized clinical trials underway. Review the role of radiosurgery in the management of patients with brain metastases and emphasize the major prognostic factors. Review the recently initiated clinical trials for brain metastases using radiosurgery. Review the role of radiosurgery in the management of benign tumors with specific emphasis on meningioma and acoustic neuroma. Emphasize the rationale for fractionation and present the preliminary results of fractionated stereotactic radiation. Stereotactic localization techniques, originally designed for neurosurgery, have been used to delivery high single doses of radiation to small intracranial targets for more than 25 years, a technique referred to as stereotactic radiosurgery. Radiosurgery has proven to be an attractive alternative to surgery in the management of several benign tumors, such as vestibular schwannomas with better preservation of hearing and facial nerve function than microsurgical resection. For other benign tumors such as meningioma and pituitary adenoma, preliminary results are promising, but longer range studies to confirm high tumor control rates are necessary. For patients with malignant glioma, radiosurgery has been used to escalate the radiation dose to enhance tumor control following surgery and radiation therapy. The rationale for this is grounded in the recent confirmatory randomized prospective trial verifying the value of brachytherapy in this disease. The results of radiosurgery from single institutional experiences for primary and recurrent malignant glioma indicate a palliative benefit as well as a potential survival benefit in a select sub-group of patients based on the appropriate mix of prognostic criteria such as patient age, performance status, tumor size and extent of resection

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2010. The report covers both current status and key trends. By design, the report does not provide analysis, discuss current issues, or forecast the future. Many of the trends reflect the increasing significance of renewable energy relative to conventional energy sources (including coal, gas, oil, and nuclear). By 2010, renewable energy had reached a clear tipping point in the context of global energy supply. Renewables comprised fully one quarter of global power capacity from all sources and delivered 18 percent of global electricity supply in 2009. In a number of countries, renewables represent a rapidly growing share of total energy supply-including heat and transport. The share of households worldwide employing solar hot water heating continues to increase and is now estimated at 70 million households. And investment in new renewable power capacity in both 2008 and 2009 represented over half of total global investment in new power generation. Trends reflect strong growth and investment across all market sectors-power generation, heating and cooling, and transport fuels. Grid-connected solar PV has grown by an average of 60 percent every year for the past decade, increasing 100-fold since 2000. During the past five years from 2005 to 2009, consistent high growth year-after-year marked virtually every other renewable technology. During those five years, wind power capacity grew an average of 27 percent annually, solar hot water by 19 percent annually, and ethanol production by 20 percent annually. Biomass and geothermal for power and heat also grew strongly. Much more active policy development during the past several years culminated in a significant policy milestone

    2013-01-01

    Subjective status, an individual’s perception of her socioeconomic standing, is a robust predictor of physical health in many societies. To date, competing interpretations of this correlation remain unresolved. Using longitudinal data on 8,430 older adults from the 2000 and 2007 waves of the Indonesia Family Life Survey, we test these oft-cited links. As in other settings, perceived status is a robust predictor of self-rated health, and also of physical functioning and nurse-assessed general health. These relationships persist in the presence of controls for unobserved traits, such as difficult-to-measure aspects of family background and persistent aspects of personality. However, we find evidence that these links likely represent bi-directional effects. Declines in health that accompany aging are robust predictors of declines in perceived socioeconomic status, net of observed changes to the economic profile of respondents. The results thus underscore the social value afforded good health status. PMID:23453318

    Galvin, Kathleen A; Beeton, Tyler A; Boone, Randall B; BurnSilver, Shauna B

    This study assesses the nutritional status of Maasai pastoralists living in a period of great social, economic and ecological changes in Kajiado County, southern Kenya. Data on weight, height, skinfolds, and circumferences were collected from 534 individuals in the year 2000. The data were used to describe mean differences in human nutrition between ages, sexes, and within and among three Group Ranches. Nutritional data and diet recall data were compared with past studies of Maasai nutrition from 1930 to 2000. Results indicate that nutritional status is poor and has remained so despite numerous changes to the social-ecological system including livelihood diversification, sedentarization, human population growth and decreased access to vegetation heterogeneity. Imbirikani Group Ranch had better access to infrastructure and markets and some measures of nutritional status were better than for individuals in other group ranches. However, nutritional status remains poor despite transitioning to greater market integration.
