    Full Text Available Para la corrección quirúrgica de la afaquia existen en la actualidad varias técnicas quirúrgicas que permiten fijar los lentes intraoculares plegables o rígidos en cámara posterior suturados al iris o al sulcus ciliar. En estas circunstancias el cirujano determinará cuándo, dónde y el tipo de lente mejor a implantar. Se presenta un paciente con una afaquia traumática del ojo izquierdo, con agudeza visual sin corrección de movimiento de mano a 1 m. Se le realizó implante secundario de lente intraocular plegable de cámara posterior suturada al iris. En el examen biomicroscópico en lámpara de hendidura del ojo izquierdo se observó midriasis media paralítica, refracción dinámica de +11,00 (0,6 y tensión ocular normal. Se le realizó examen por bimicroscopía indirecta sin alteración. Al mes de operado la agudeza visual mejor corregida alcanzó la unidad de visión. Las complicaciones presentadas fueron ovalización de la pupila y depósitos de pigmentos de iris en el lente intraocular.

    Full Text Available Abstract Background Bladder desensitization has been investigated as an alternative treatment for refractory detrusor overactivity. Most open and controlled clinical trials conducted with intravesical RTX showed that desensitization delays the appearance of involuntary detrusor contractions during bladder filling and decreases the number of episodes of urgency incontinence. Urgency is being recognised as the fundamental symptom of overactive bladder (OAB, a symptomatic complex which recent epidemiological studies have shown to affect more than 10% of the Western population. As anti-muscarinic drugs, the first line treatment for OAB, are far from being able to fully control urgency, the opportunity to test other therapeutic approaches is created. The present work was, therefore, designed as an exploratory investigation to evaluate the effect of bladder desensitization on urinary urgency. Methods Twenty-three OAB patients with refractory urgency entered, after given informed consent, a 30 days run-in period in which medications influencing the bladder function were interrupted. At the end of this period patients filled a seven-day voiding chart where they scored, using a 0–4 scale, the bladder sensations felt before each voiding. Then, patients were instilled with 100 ml of 10% ethanol in saline (vehicle solution and 30 days later a second seven-day voiding chart was collected. Finally, patients were instilled with 100 ml of 50 nM RTX in 10% ethanol in saline. At 1 and 3 months additional voiding charts were collected. At the end of the vehicle and 3 months period patients were asked to give their subjective impression about the outcome of the treatment and about the willingness to repeat the previous instillation. Results At the end of the run-in period the mean number of episodes of urgency per week was 71 ± 12 (mean ± SEM. After vehicle instillation, the mean number of episodes of urgency was 56 ± 11, but only 4 patients (17% considered

    Background and purpose: To assess the correlation between the LENT (late effects on normal tissue) SOMA (subjective objective management analytic) system and the Franco-Italian glossary scores of late morbidity in cervical cancer patients treated with radiation, and to compare the ability of the scoring systems to detect differences between radiation treatment groups. Materials and methods: The study was retrospective. Patients, invited to take part in the study, had radiotherapy for cervical cancer and had a minimum of 3 years follow-up with no evidence of recurrence. One hundred patients agreed to take part. LENT subjective data were obtained using a patient questionnaire approach in order to complete the scales as published. The LENT objective, management and Franco-Italian glossary scores were obtained by a physician. Correlations between scores and differences between treatment groups were examined using non-parametric tests. Results: The average LENT SOMA scores had a greater resolution than the maximum scores, and using the maximum score alone underestimated treatment morbidity. The Franco-Italian glossary scores correlated strongly with the LENT objective scores (ρ=0.61, P<0.0005), and less strongly with the LENT subjective scores (ρ=0.45, P<0.0005). Significant differences in morbidity between the radiation treatment groups were measured using both the LENT SOMA system and the Franco-Italian glossary. Conclusions: The maximum and average LENT scores should be reported for each subsite. The LENT objective scores correlated well with the scores obtained using the established Franco-Italian glossary, but the LENT system provided additional information on subjective treatment effects. Both systems were able to measure significant differences in morbidity between radiation treatment groups. In conclusion, the LENT SOMA system is a valid and comprehensive approach for scoring the late normal tissue effects of radiotherapy

    Full Text Available OBJETIVO: Compreender, por meio de figuras e funções matemáticas do cone, as lentes progressivas e mostrar que elas não são lentes multifocais porque, nelas, a refração da luz não obedece as leis da geometria euclidiana. MÉTODOS: Foi feito um estudo da geometria analítica do cone, com o programa de computador Auto-CAD 14, dando enfoque óptico às figuras geométricas obtidas com a sua secção. RESULTADOS: Pela análise das figuras obtidas da secção do cone, pudemos observar as superfícies que compõem as lentes progressivas. Estas superfícies são compostas de elipse, círculo, parábola e hipérbole. Diferente do que é dito na literatura, encontramos as elipses com diâmetro maior nas ordenadas e de mesmo sentido seguida por duas superfícies inferiores que são parábola e hipérbole e não o contrário. CONCLUSÕES: As lentes progressivas diferentemente das lentes multifocais apresentam prismas nos centros ópticos como decorrência da sua estrutura. No final, fizemos análise das suas formas mostrando o limite teórico da sua evolução.

  11. Dimensions of sensation assessed in urinary urgency: a systematic review.

    Das, Rebekah; Buckley, Jonathan; Williams, Marie

    2013-10-01

    Urinary urgency is an adverse sensory experience. Confirmation of the multidimensional nature of other adverse sensory experiences such as pain and dyspnea has improved the understanding of neurophysiological and perceptual mechanisms leading to innovations in assessment and treatment. It has been suggested that the sensation of urgency may include multiple dimensions such as intensity, suddenness and unpleasantness. In this systematic review we determine which dimensions of sensation have been assessed by instruments used to measure urinary urgency. A systematic search was undertaken of MEDLINE, Embase, AMED, CINAHL, Ageline, Web of Science, InformIT Health and Scopus databases to identify studies that included assessments of urinary urge or urgency. Articles were included in the analysis if they were primary studies that described the method used to measure urge/urgency in adults and published in English in peer reviewed publications since January 1, 2000. Articles were excluded from study if urgency was measured only in conjunction with other symptoms (eg frequency or incontinence) or if there was no English version of the instrument. Secondary analyses and systematic reviews were retained to hand search references for additional primary studies. Data were extracted for the instruments used to measure urge/urgency. For each instrument the items specific to urinary urgency were reviewed using a prospectively developed categorization process for the sensory dimension and the measurement metric. Items used to assess urinary urgency were collated in a matrix (sensory dimensions vs assessment metric). The most frequently used dimensions, metrics and combinations were descriptively analyzed. After removal of duplicate articles 1,048 full text articles were screened and 411 were excluded, leaving 637 eligible articles from which data were extracted. A total of 216 instruments were identified which were 1 of 6 types, namely 1) wider symptom questionnaires, 2) urgency

Foram adaptadas lentes de contato filtrantes coloridas em dois portadores de discromatopsias, um com deutanopia e outro com acromatopsia. No primeiro, adaptou-se lente rígida filtrante, de polimetilmetacrilato (PMMA, vermelha, no olho não dominante, com o objetivo de melhorar a discriminação de cores. No segundo, colocou-se lente filtrante gelatinosa, de uso diário, de coloração marrom escuro com pupila âmbar, visando melhorar o ofuscamento. No primeiro caso, o paciente manteve inalterada a acuidade visual e também o contraste, porém demonstrou melhora na discriminação das cores ao teste de PV-16. No segundo caso, houve melhora subjetiva acentuada do ofuscamento tanto em ambiente interno, como externo. A acuidade visual e a visão de cores permaneceram sem alterações. Os achados sugerem a possibilidade de contarmos com as lentes de contato filtrantes coloridas como importante auxílio para a melhora na discriminação de cores e ofuscamento, nas discromatopsias.

    Survival of humanity, on this planet, may depend, heavily, on coping with advancing technology of nuclear missiles. Let us consider critical alternatives of powerful governments: democracy, as an alternative to dictatorship. Democracy is based on free elections, as a government of the people, by the people and for the people. Democracy is a historical urgency, in the age of inter-continental nuclear missiles, computerized on a push-button, conceivably controllable by a very powerful, miscalculating and/or insane, dictator, capable of producing global nuclear holocaust, on our entire planet. Diplomacy, together with supporting activities, should be utilized, to help, in important steps, at this time, for achieving democracy in critical areas.

    Full Text Available The religious practices generate some important calendar effects on the stock markets evolutions. This paper explores the impact on stock markets of two periods from the Catholic Church Calendar, Advent and Lent, for the period January 2009 � May 2017. We employ as data the closing daily values of stock exchanges indexes from five countries where the main religion is the Roman Catholicism: Argentina, Brazil, Chile, Hungary and Mexico. The sample of data used in the investigation is divided in two sub � samples: the first, from January 2009 to December 2012, covers a period when international stock market recovered after the 2007 � 2008 crisis, while the second sub � sample, from January 2013 to May 2017, corresponds, at a global scale, to a relative normal period. We employ GARCH models to reveal the impact of the Advent and Lent on the prices returns and volatility. For the first sub-sample we found no effect on returns but a decline in volatility during Advent for all the five indexes and during Lent only for the stock market from Brazil. For the second sub-sample the results indicate a decline in returns during Advent, for the stock markets from Argentina and Chile, but no impact on volatility. Such results could be explained by the circumstances specific to the religious practices but also by the inference of other calendar effects.

  20. Exploring divergent trajectories: Disorder-specific moderators of the association between negative urgency and dysregulated eating.

    Science.gov (United States)

    Racine, Sarah E; Martin, Shelby J

    2016-08-01

    Negative urgency (i.e., the tendency to act impulsively when experiencing negative emotions) is a well-established risk factor for dysregulated eating (e.g., binge eating, loss of control eating, emotional eating). However, negative urgency is transdiagnostic, in that it is associated with multiple forms of psychopathology. It is currently unclear why some individuals with high negative urgency develop dysregulated eating while others experience depressive symptoms or problematic alcohol use. Investigating disorder-specific moderators of the association between negative urgency and psychopathology may help elucidate these divergent trajectories. The current study examined interactions among negative urgency and eating disorder-specific risk factors specified in the well-established dual-pathway model of bulimic pathology (i.e., appearance pressures, thin-ideal internalization, body dissatisfaction, dietary restraint). We hypothesized that these interactions would predict dysregulated eating, but not depressive symptoms or problematic alcohol use. Latent moderated structural equation modeling was used to test this hypothesis in a large (N = 313) sample of female college students. Negative urgency was significantly associated with dysregulated eating, depressive symptoms, and problematic alcohol use. However, interactions among negative urgency and dual-pathway model variables were specific to dysregulated eating and accounted for an additional 3-5% of the variance beyond main effects. Findings suggest that eating disorder-specific risk factors may shape negative urgency into manifesting as dysregulated eating versus another form of psychopathology. Future research should use longitudinal designs to further test the impact of interactions among disorder-specific risk factors and negative urgency on divergent psychopathology trajectories.

    2016-11-18

    Hypertensive crises lumped several clinical situations with different seriousness and prognosis. The differences between hypertensive urgency and hypertensive emergency depends on if this situation involves a vital risk for the patient. This risk is defined more by the severity of the organ damage than for the higher values of blood pressure. The hypertensive urgency not involves an immediately risk for the patient, for these reason, the treatment can be completed after discharged. Otherwise, the hypertensive emergency is a critical clinical condition that requires hospital assistance. Faced with a patient, with severe hypertension, asymptomatic or with unspecific symptoms we must be careful. First, we need to confirm the values of blood pressure, with several measures of blood pressure and investigate and treat factors, which triggered this situation. The objective of medical treatment for hypertensive urgency is to reduce blood pressure values (at least 20% of baseline values) but to avoid sudden reduction of these values. In hypertensive urgencies rapid acting drug should not be used because of the risk of ischemic stroke and use drugs with longer half-life. The cardiovascular risk of these patients is higher than that do not suffer hypertensive crisis. The treatment must be personalized in each hypertensive emergency and intravenous it’s the best route to treat these patients.

    The aim of this paper was to identify factors affecting the urgency of nursing home placement after introduction of public long-term care insurance. The subjects were families including at least one disabled elderly person and one another family member in two cities in Chugoku Prefecture. The measure of the urgency of placement was 0 if the family did not submit any application for placement, 1 if the care managers judged that the elderly person should enter in the future when she/he really needs placement, 2 if the care managers judged that she/he might be able to wait for a short while, and 3 if the care managers judged that she/he should enter as early as possible. Our estimation method was by ordered logit model. The dependent variable was the measure of the urgency and the independent variables were several attributes of the families. In the estimation, we considered the possibility that the coefficients depend on categories of dependent variable. We obtained data for 146 waiting families and 494 others (total 640). There were differences in the urgency of placement among waiting elderly as follows "she/he should enter as early as possible" (28.8%); "she/he can wait for a while" (32.2%), "she/he should enter in the future when she/he really needs placement" (39.0%). The results of multivariate analyses showed that the urgency of placement correlated significantly with the severity of the elderly persons disabilities, the number of primary caregivers' self-symptoms, the family members' negative attitude toward caregiving, residing in city A, not having one's own house and limited use of short-stay facilities due to the circumstances of the providers. When judging the urgency of placement, we should consider not only whether the applicant has submitted a request for a nursing home or not, but also differences among the waiting families. The urgency of placement correlates significantly with severity of disability of the elderly person, the number of primary

    Research on relational aggression (indirect and social means of inflicting harm) has previously focused on adolescent populations. The current study extends this research by exploring both the frequency of perpetrating and being the target of relational aggression as it relates to alcohol use outcomes in a college population. Further, this study examines whether positive urgency (e.g., acting impulsively in response to positive emotions) and negative urgency (e.g., acting impulsively in response to negative emotions) moderate the relationship between relational aggression and alcohol outcomes. In this study, 245 college students (65.7% female) completed an online survey. Results indicated greater frequency of perpetrating relational aggression, higher levels of positive urgency, or higher levels of negative urgency was associated with more negative consequences. Further, negative urgency moderated the relationship between frequency of perpetrating aggression and consequences such that aggression was more strongly associated with consequences for those high in urgency. Counter to the adolescent literature, the frequency of being the target of aggression was not associated with more alcohol use. These findings suggest that perpetrators of relational aggression may be at particular risk for negative alcohol-related consequences when they act impulsively in response to negative, but not positive, emotions. These students may benefit from interventions exploring alternative ways to cope with negative emotions.

This cross-sectional study of nontreatment-seeking smokers examined the relationship between urgency, level of nicotine dependence, and smoking reinforcement expectancies. Both positive and negative urgency were associated with nicotine dependence. Mediational analyses illustrated that smoking reinforcement expectancies significantly accounted for urgency-dependence relations, with negative reinforcement expectancies displaying incremental mediational effects. If replicated and extended, these findings may support the use of treatments that modify beliefs regarding smoking reinforcement outcomes as a means of buffering the risk of nicotine dependence carried by urgency.

  17. [Hypertensive urgency or high blood pressure variability?

    Science.gov (United States)

    Rodionov, A V

    Hypertensive urgency (HU) is a common reason particularly for elderly patients to seek medical advice. Severe asymptomatic hypertension and situational high blood pressure (BP) in patients with its high variability is frequently taken as HU. The use of short-acting antihypertensive drugs is not only indicated in these situations, but it may also increase the risk of cardiovascular events (CVE). Over the past decade, increased BP variability is an independent predictor for a higher risk of CVE. Among the major groups of antihypertensive drugs, there are calcium antagonists, mainly amlodipine, which has the greatest potential to reduce BP variability. Thus, calcium antagonists can be considered as first-line drugs for patients with high BP variability.

  18. Associations between nicotine dependence, anhedonia, urgency and smoking motives.

    Models of nicotine dependence have suggested that the association between urgency, a subconstruct of impulsivity, and smoking behaviors may be mediated by motivations. Motives that are driven by expectations that smoking will relieve negative affect or increase positive affect may be especially salient in persons who have depression symptoms such as anhedonia. Support for associations between symptoms of depression, urgency, and addiction has been found for alcohol dependence, but empirical analysis is lacking for an interactive effect of urgency and depression symptoms on nicotine dependence. The current study investigated relationships among the urgency facet of impulsivity, anhedonia, smoking motives, and nicotine dependence with secondary analyses of a sample of 1084 daily smokers using simultaneous moderation and multiple mediation analyses. The moderation analysis revealed that although urgency was significantly associated with smoking at average or higher levels of anhedonia, it was unrelated to smoking when few anhedonia symptoms were endorsed. Further, multiple mediation analyses revealed that the smoking motives of craving, cue exposure, positive reinforcement, and tolerance significantly mediated the relationship between urgency and nicotine dependence. Results suggest that models of alcohol addiction that include an interactive effect of urgency and certain symptoms of depression may be applied to nicotine dependence. Examination of the multiple mediational pathways between urgency and nicotine dependence suggests directions for intervention efforts. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A principal ferramenta de trabalho do astrônomo é o telescópio. O manuseio do mesmo é sempre motivo de enorme curiosidade por parte de alunos do ensino fundamental ou médio e até mesmo dos respectivos professores. Visando propiciar o acesso de alunos e professores ou interessados em geral a uma luneta de fácil construção, com materiais alternativos, de fácil localização no comércio, de baixo custo, resistente ao manuseio de alunos, simplificamos a montagem de uma luneta construída com lente de óculos, de 1 ou 2 graus positivos, e monóculo de fotografia, publicado por este autor no CCEF, vol.11(3), 212, 1994. Esta luneta, a qual permite ver as crateras lunares, apresentava como maior dificuldade de construção o tripé e o local de formação da imagem. Substituímos o tripé de madeira por uma simples garrafa PET de 2 litros cheia d'água. No lugar da ocular usamos a lente do monóculo de fotografia (ou visor de fotografia) encaixado dentro de uma bucha de redução curta, de 40 x 32 mm, e esta não mais dentro de uma luva (conexão hidráulica) de 40 mm de diâmetro, mas sim encostada no próprio tubo de PVC móvel (o qual permite o ajuste do foco) de 40 mm de diâmetro e presa a este por outro tubo de 40 mm de diâmetro e 10 cm de comprimento, serrado ao longo do seu comprimento. Com isto podemos ajustar a posição deste tubo de 10 cm também para que uma das suas extremidades coincida com o local de formação da imagem. Desta forma o observador saberá o local exato da formação da imagem, o que não era evidente na montagem anterior e causava uma dificuldade inicial até se descobrir a posição exata em que se deveria colocar o olho. Deste maneira, a montagem inicial que já era simples ficou ainda mais simples, mais barata e mais confortável para o uso. Um exemplar da mesma será exposto durante a XXIX Reunião Anual da Sociedade Astronômica Brasileira para inspeção e uso dos participantes.

    Full Text Available El queratocono es una enfermedad degenerativa que se caracteriza por un adelgazamiento progresivo del estroma corneal y la deformidad en forma de cono de la córnea, lo cual provoca astigmatismo irregular y miopía elevada. Se realizó una revisión de artículos publicados referentes al implante de lentes intraoculares fáquicos como alternativa de tratamiento en esta entidad, la cual continúa siendo de difícil manejo en la actualidad. En ametropías con alto componente esférico y cilíndrico, el uso de lente fáquico tórico mostró óptimos resultados visuales. De igual modo el uso de lentes de soporte angular "estira" la córnea y achata el área apical central a través de sus hápticas, con lo que reduce la ectasia corneal y el astigmatismo irregular asimétrico. A su vez, la presencia del lente intraocular entre la pupila y la córnea crea una barrera física que evita la acción de la corriente de humor acuoso contra la córnea y, por consiguiente, hay una estabilización de todos los parámetros de la córnea después de la implantación del lente. La literatura reporta combinación de implantes de lentes fáquicos posterior a anillos intraestromales y crosslinking con un excelente resultado funcional: incrementa en forma importante la agudeza visual sin corrección, mejora las topografías corneales y las aberraciones de alto orden y disminuye la posibilidad de requerir un trasplante de córnea. El uso de lentes fáquicos tóricos en queratoconos estables es una alternativa terapéutica válida como tratamiento de la ametropía que acompaña a esta patología.

  9. A comprehensive model of food addiction in patients with binge-eating symptomatology: The essential role of negative urgency.

    Wolz, Ines; Granero, Roser; Fernández-Aranda, Fernando

    2017-04-01

    Food addiction has been widely researched in past years. However, there is a debate on the mechanisms underlying addictive eating and a better understanding of the processes associated to these behaviors is needed. Previous studies have found characteristic psychological correlates of food addiction, such as high negative urgency, emotion regulation difficulties and low self-directedness, in different samples of adults with addictive eating patterns. Still, it seems difficult to disentangle effects independent from general eating disorder psychopathology. Therefore, this study aimed to test a comprehensive model under control of eating disorder severity, in order to find independent predictors of food addiction. 315 patients with eating disorder diagnoses on the binge-eating spectrum were assessed in personality, emotion regulation, negative urgency, eating disorder symptomatology, and food addiction by self-report. Hypothesis-driven structural equation modeling was conducted to test the comprehensive model. The only independent predictor found for food addiction was negative urgency, while self-directedness and emotion regulation predicted negative urgency and were highly related to eating disorder symptomatology, but not to food addiction. Altogether the model suggests that low self-directedness and difficulties in emotion regulation are related to higher eating disorder symptomatology in general. Those patients who, in addition to these traits, tend to act impulsively when in negative mood states, are at risk for developing addictive eating patterns. Urgency-based treatments are therefore recommended for this subgroup of patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To study the clinical significance of presenting blood pressure parameters and heart rate in patients with hypertensive crisis. In patients admitted with hypertensive crisis between January 2011 and May 2011, demography, mode of presentation, co-morbidities, blood pressure readings, and heart rate at presentation were documented. Further clustering of hypertensive crisis into emergency or urgency was based on the presence or absence of target organ involvement. The relationship between blood pressure parameters, heart rate, and other variables was analyzed. 189 patients in sinus rhythm were enrolled in this pilot study. The rate of hypertensive urgency was 56 %, whereas the rate of hypertensive emergency was 44 %, respectively. Subjects with hypertensive emergency had a higher mean heart rate (93 ± 22.7 bpm) than those with urgency (81 ± 11.5 bpm) (P = 0.015). Women had higher heart rates (92 ± 18.5 bpm) than men (86 ± 17.6 bpm) (P = 0.014). Heart rates below 100 bpm had a specificity of 94 %, classifying patients as hypertensive urgency. Tachycardia had a powerful statistical association with hypertensive left ventricular failure (P hypertensive crisis. Normal heart rate is characteristic of hypertensive urgency. Tachycardia in this setting is an ominous sign and denotes hypertensive complications in particular left ventricular failure. Among diabetics, elevated heart rate is associated with poor glycemic control.

    The purpose of this study was to characterize the urinary microbiota in women who are planning treatment for urgency urinary incontinence and to describe clinical associations with urinary symptoms, urinary tract infection, and treatment outcomes. Catheterized urine samples were collected from multisite randomized trial participants who had no clinical evidence of urinary tract infection; 16S ribosomal RNA gene sequencing was used to dichotomize participants as either DNA sequence-positive or sequence-negative. Associations with demographics, urinary symptoms, urinary tract infection risk, and treatment outcomes were determined. In sequence-positive samples, microbiotas were characterized on the basis of their dominant microorganisms. More than one-half (51.1%; 93/182) of the participants' urine samples were sequence-positive. Sequence-positive participants were younger (55.8 vs 61.3 years old; P = .0007), had a higher body mass index (33.7 vs 30.1 kg/m(2); P = .0009), had a higher mean baseline daily urgency urinary incontinence episodes (5.7 vs 4.2 episodes; P urinary incontinence episodes, -4.4 vs -3.3; P = .0013), and were less likely to experience urinary tract infection (9% vs 27%; P = .0011). In sequence-positive samples, 8 major bacterial clusters were identified; 7 clusters were dominated not only by a single genus, most commonly Lactobacillus (45%) or Gardnerella (17%), but also by other taxa (25%). The remaining cluster had no dominant genus (13%). DNA sequencing confirmed urinary bacterial DNA in many women with urgency urinary incontinence who had no signs of infection. Sequence status was associated with baseline urgency urinary incontinence episodes, treatment response, and posttreatment urinary tract infection risk. Copyright © 2015 Elsevier Inc.

    2012-10-01

    Negative affect has been consistently linked with substance use/problems in prior research. The present study sought to build upon these findings by exploring how an individual's characteristic responding to negative affect impacts substance abuse risk. Trait negative affect was examined in relation to substance abuse outcomes along with two variables tapping into response to negative affect: distress tolerance, an individual's perceived ability to tolerate negative affect, and negative urgency, the tendency to act rashly while experiencing distress. Participants were 525 first-year college students (48.1% male, 81.1% Caucasian), who completed self-report measures assessing personality traits and alcohol-related problems, and a structured interview assessing past and current substance use. Relations were tested using zero-inflated negative binomial regression models, and each of the personality variables was tested in a model on its own, and in a model where all three traits were accounted for. Negative urgency emerged as the best predictor, relating to every one of the substance use outcome variables even when trait negative affect and distress tolerance were accounted for. These findings suggest that negative urgency is an important factor to consider in developing prevention and intervention efforts aimed at reducing substance use and problems.

RESULTS: The etiological agent was identified in 239 patients. Bacterial isolates accounted for 166 (69.46% cases, Acanthamoeba for 95 (39.75% cases and fungi for 4 (1.67% cases. Among the bacterial infections, coagulase-negative Staphylococcus was demonstrated in 74 cases, while Pseudomonas spp was found in 32 patients. All coagulase negative Staphylococcus and Pseudomonas were susceptible to ciprofloxacin and ofloxacin. Resistance to gentamicin was documented in a single case of Pseudomonas. Fourth-generation flouoroquinolone resistance was not observed among Pseudomonas cases. CONCLUSION: Coagulase-negative Staphylococcus was the most frequent isolate, and such data must be considered when determining empiric treatment. Second-generation fluoroquinolones ciprofloxacin and ofloxacin and fourth-generation fluoroquinolones moxifloxacin and gatifloxacin showed a good antibacterial profile and therefore could be good options for initial management.OBJETIVO: A ceratite microbiana associada ao uso de lente de contato é uma condição clínica grave, com risco de perda visual e cuja incidência vem aumentando progressivamente.

    Full Text Available Os implantes em olhos fácicos apresentam-se como uma opção para a correção de altas ametropias. De acordo com sua localização podem ser classificados como de câmara anterior ou posterior, sendo que os primeiros subdividem-se em fixação iriana ou de suporte angular. Além da correção da miopia, as lentes de fixação iriana apresentam modelos para hipermétropes e astigmatas. Várias modificações no desenho das lentes foram propostas nas últimas décadas com a finalidade de reduzir complicações tardias, como a perda endotelial progressiva. Cuidados no intraoperatório devem ser tomados de forma a diminuir a perda endotelial aguda relacionada ao trauma. Avanços nos métodos de triagem pré-operatória também melhoraram a segurança do procedimento. A estimativa do poder dióptrico é baseada nos cálculos de Van der Heijde, sendo dependente da profundidade de câmara anterior, do equivalente esférico da refração e da média ceratométrica. Resultados a longo prazo demonstram a eficácia, previsibilidade e segurança do procedimento. Dependendo do modelo, além da possibilidade de perda endotelial, outras possíveis complicações incluem: irite, dispersão pigmentar, atrofia de íris, ovalização pupilar, rotação, descentração ou deslocamento da lente, hipertensão ocular e bloqueio pupilar. Modelos dobráveis atualmente disponíveis vêm apresentado resultados bastante promissores com redução da taxa de complicações.

    A estatística de lentes gravitacionais constitui uma poderosa ferramenta utilizada na obtenção de vínculos sobre parâmetros cosmológicos, principalmente sobre modelos com uma constante cosmológica. Embora de forma às vezes controversa, antes de 1998, a análise tradicional mostrava que modelos com o parâmetro de densidade da matéria da ordem da unidade são preferidos. Esse resultado começou a ser questionado, alguns anos atrás, com as indicações, advindas da análise de supernovas com alto valor de desvio para o vermelho, de que nosso Universo está acelerando. Atualmente há enorme interesse em saber qual é a natureza da componente responsável pela aceleração cósmica. Energia escura é a denominação usual dessa componente e sua característica principal é possuir pressão negativa. Nos modelos cosmológicos tradicionais, além da energia escura, considera-se também uma outra componente de origem desconhecida. Ela é denominada matéria escura e possui pressão nula. Mais recentemente modelos unificadores em que energia escura e matéria escura são manifestações distintas de um mesmo fluido (altas densidades matéria escura, baixas densidades energia escura) foram sugeridos. Um desses modelos é conhecido como Gás de Chaplygin Generalizado que é o modelo que investigaremos. Em nosso trabalho apresentamos vínculos sobre parâmetros desse modelo usando a estatística de lentes gravitacionais. Usamos observações de quasares na faixa do visível e consideramos extinção em nosso estudo. Análises semelhantes anteriores com esse tipo de objetos e que não consideram extinção são inconsistentes. Comparação dos vínculos obtidos através de lentes gravitacionais com outros advindos de outros testes será também apresentada.

    Urgency for prompt and coordinated action by industrialized countries is emphasized in this analysis of the earth's most pressing environmental problems - desertification, acid rain, deforestation, the greenhouse effect and ozone depletion. In the analysis of the chemical, physical, thermochemical and climatic processes (e.g., ozone reactions with chlorofluorocarbons, Antarctic atmospheric vortex circulation, volcanic eruptions, the earth's water and carbon cycles, cyclic global temperature variations, etc.) governing the formation and modification of the various environmentally destabilizing phenomena, and in the assessments of the severity and duration of the effects, the paper evidences global and socio-economic aspects relative to the probable causes and proposed solutions. The author states that whereas greater investment by industrialized countries in environmental protection and technology transfer programs is essential to save the earth's natural resources, overall positive results can be achieved only through a contemporaneous change in social values to favour the sharing of the earth's wealth among nations and future generations

    Hypertensive urgency/emergency is a common and potentially life threatening condition that is characterised by a rapid and strong increase in blood pressure. It is estimated that hypertensive urgencies/emergencies account for 25 % of all patient visits in the medical section of emergency departments. Between 24 September 2007 and 06 September 2008, we investigated 195 persons with hypertensive events who were admitted to the emergency unit of the University Clinic St. Josef Hospital in Bochum. After stabilization of blood pressure, the patients were sent to the ward for further evaluation. Aldosterone, renin, and cortisol levels were monitored during the first 24 hours. Blood was taken at 8 am after 2 hours in supine position and after mobilization at 10 am. Meteorological data at the time of admission were analyzed for potential associations with the temporary accumulation of hypertensive events. The meteorological parameters were air temperature TA, relative humidity RH, air pressure P, and sunshine duration SD, observed at the meteorological station in Duesseldorf (airport). In addition, perceived temperature PT was calculated and included in the analysis. First results indicate that the hypertensive events occurred on days when TA departed on average -0.28 K (95 % confidence interval: -0.59 to -0.03 K) and PT deviated on average -0.43 K (-0.82 to -0.04) from the respective values of the preceding day. On days without hypertensive events TA was on average 0.21 (-0.08 to 0.49) and PT was on average 0.32 K (-0.04 to 0.68) higher than on the day before. Days with and days without cases of hypertensive events were, with respect to the daily TA and PT changes, significantly different (TA: p = 0.012; PT: p = 0.003). On days with lower PT than on the previous day the probability of a hospital admission due to a hypertensive event was more than twice as high as on days with higher PT than on the day before. These first results indicate a potential relationship between

    Background Young adults with higher trait urgency (i.e., a tendency to act rashly in response to heightened affect) may be especially vulnerable to heavy drinking. The current study examined 1) the influence of urgency on daily relations between affect and drinking to intoxication, and 2) whether urgency influenced the effectiveness of naltrexone (vs. placebo) for reducing alcohol use. Methods This study is a secondary analysis of data from 126 (n=40 female) heavy drinking young adults, ages 18–25, enrolled in a double-blind, 8-week clinical trial comparing brief motivational intervention and either naltrexone or placebo. Multilevel models examined whether trait urgency moderated daily relations between positive and negative affect and drinking to intoxication, measured by an estimated blood-alcohol concentration (eBAC) at or above the legal limit (≥0.08g%). Person-level interactions examined whether naltrexone was more effective than placebo at reducing the odds of eBAC≥0.08g% for individuals with higher vs. lower trait urgency. Results On days of greater within-person positive or negative affect, young adults with higher urgency were more likely to drink to intoxication than those with lower urgency. Naltrexone reduced the odds of drinking to intoxication significantly more than placebo, independent of positive or negative urgency. Conclusions Although naltrexone treatment reduced drinking overall, young adults with higher trait urgency were still at increased risk for hazardous drinking following times of strong positive or negative mood. Targeted interventions are needed to reduce the risk of heavy drinking among young adults with high trait urgency. PMID:27875802

    Errors in drug administration are the second cause of errors in hospitalized patients. Children are a high risk group. Besides, pressure in care interventions at emergency department leads to increase incidence errors. Determining nurses' knowledge about the most common drug doses at pediatric urgency department. Descriptive transversal study. We collected data from nurses of 14 pediatric emergency departments of Madrid. With an "ad hoc" questionnaire we collected the following data during five days in January of 2014: demographic, knowledge of responsibility in administration and doses of drugs. Global descriptive analysis was made and it was stratified by hospital and work experience. The answer rate was 114 (34.9%). Only 80 (70.8%) of nurses confirm doses before their administration; 20 (18.6%) think that a wrong prescription that they administer is not their responsibility. There is a high knowledge in the group with more than five years of work experience, except for sedative-analgesic drugs (p<0.05). The average score obtained was 3.8 of 10 (1.99). Nurses' knowledge about drug doses is low. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    2015-04-01

    Binge eating has been found to be associated with urgency (the tendency to act impulsively in response to negative affect) and emotional awareness (i.e., attention to emotions, clarity of emotions). The present study tested the hypothesis that the relation between binge eating and urgency would be moderated by emotional awareness, over and above negative affect. Participants were 249 female college students. Items from the Trait Meta Mood Scale (TMMS), the Urgency subscale of the UPPS Impulsive Behavior Scale, and the Bulimia (B) subscale of the Eating Disorders Inventory (EDI-3) were administered. As predicted, emotional awareness moderated the link between urgency and binge eating. Both Urgency×Attention to emotions and Urgency×Clarity of emotions significantly predicted binge eating scores, even after taking into account negative affect. Consistent with past research, higher levels of urgency were associated with higher levels of binge eating, even after taking negative affect into account. However, the associations were particularly strong among individuals with low levels of attention to emotions and low levels of clarity of emotions. The findings from this study have implications for future research examining binge eating. Copyright © 2015 Elsevier Ltd. All rights reserved.

  4. Negative and positive urgency may both be risk factors for compulsive buying.

    2014-06-01

    Descriptions of compulsive buying often emphasize the roles of negative moods and trait impulsivity in the development of problematic buying habits. Trait impulsivity is sometimes treated as a unidimensional trait in compulsive buying research, but recent factor analyses suggest that impulsivity consists of multiple components that are probably best treated as independent predictors of problem behavior. In order to draw greater attention to the role of positive moods in compulsive buying, in this study we tested whether negative urgency (the tendency to act rashly while in negative moods) and positive urgency (the tendency to act rashly while in positive moods) account for similar amounts of variance in compulsive buying. North American adults (N = 514) completed an online survey containing the Richmond Compulsive Buying Scale (Ridgway, Kukar-Kinney & Monroe, 2008), established measures of positive and negative urgency (Cyders et al., 2007), ad hoc measures of buying-specific positive and negative urgency, measures of extraversion and neuroticism obtained from the International Personality Item Pool (http://ipip.ori.org/), and demographic questions. In several multiple regression analyses, when demographic variables, neuroticism, and extraversion were controlled, positive urgency and negative urgency both emerged as significant predictors of compulsive buying. Whether the two urgency variables were domain-general or buying-specific, they accounted for similar amounts of variance in compulsive buying. Preventing and reducing compulsive buying may require attention not only to the purchasing decisions people make while in negative states, but also to the purchasing decisions they make while in positive states.

    The pharmacological effects of glargine, protamine zinc (PZI), and lente insulins were evaluated in nine healthy cats. A 3-way crossover study was performed and plasma concentrations of insulin and glucose were determined for 24 h after a single subcutaneous injection of each insulin at 3-day intervals. Time to onset of action did not differ between insulins. Mean time to first nadir glucose was longer for glargine (14 h) relative to PZI (4 h) and lente (5 h). PZI was biphasic in action with nadirs at 4 and 14 h with the second nadir occurring at a similar time to glargine. Nadir glucose did not differ significantly between insulin types. The duration of action was similar for glargine and PZI and was longer than that for lente insulin. Mean daily glucose after glargine and PZI were also similar and were lower than after lente insulin. Time to reach peak insulin did not differ between insulin types. Time to return to baseline insulin level for PZI was longer than glargine but did not differ significantly from lente. In conclusion, healthy cats injected subcutaneously with glargine, compared to those injected with lente insulin, have a later glucose nadir and longer duration of action. Glargine and PZI had similar durations of action in study cats but a larger study is required to obtain precise comparisons of duration of action.

    Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction. Participants (n=1906; 90% 10-11 years old, 50% female, 39% racial minorities at baseline) completed questionnaires 1-2 times per year starting in 5th grade and ending in 9th grade. Structural equation modeling allowed tests of bidirectional relationships between ever smoking and urgency controlling for pubertal status and negative affect at each wave. Incidence of ever smoking increased from 5% to 27% over time, with current smoking around 5% at the last wave. Urgency at each wave predicted ever smoking at the next wave above and beyond covariates and prior smoking (all psmoking predicted an increase in urgency at the subsequent wave above and beyond covariates and prior urgency (all psmoking increases with higher levels of urgency and urgency increases secondary to engagement in smoking. Future work should therefore explore urgency as a point of prevention for smoking and smoking cessation as a means to mitigate mood-based impulsivity. Copyright © 2017 Elsevier B.V.

    This paper introduces the development of a transient urgency monitoring system (1) to detect the early stage of a transient, (2) to identify a latent abnormal scenario, and (3) to inform an operator about the remaining time to the turbine trip when there is no operator's action. This study focused on the transients originated from the secondary system because the secondary system is recognized to be more complicated than the primary system in terms of its configuration and operation and has been a key factor to cause unplanned turbine-generator trips which can ultimately result in reactor trips. In order to make the proposed methodology practical forward, all the abnormal scenarios registered in the simulator of OPR-1000 were collected without any operator's intervention to provide the remaining time to the turbine trip and archived in the transient pattern database. The operating data periodically captured from the DCS is compared with the transient pattern database and a symptom can be detected in an initiating stage of an abnormal scenario. The transient pattern database consists of hundreds of variables, so it is difficult to speedily match patterns and to make a conclusion in a timely manner. The transient pattern database and the operating data are, therefore, converted into a smaller dimension using a dimensional compression or a feature extraction technique. In this study, principal component analysis was applied such that the principal components contain more than 99.9% of variance of the original transient patterns while the amount of information considered was less than 5% of the original data. The pattern matching between the principal components in the transient pattern database and the operating data is performed by similarity measures. Considering the different variance of an individual principal component, the final decision is determined by the weighting process for the results of similarity calculation. The most similar pattern to

    Full Text Available Se estima que aproximadamente un millón o más de pacientes se realizan cirugía refractiva al año. Es por eso que con el envejecimiento son cada día más frecuentes los pacientes con catarata, a quienes previamente se les ha efectuado cirugía refractiva. El cálculo inexacto de la potencia dióptrica de la lente a implantar en la intervención de estos es también un problema de importancia creciente y con él la sorpresa refractiva. Este es mucho más complejo de lo normal, ya que existen dos fuentes de error: la incorrecta predicción de la posición efectiva de la lente por parte de la fórmula y la determinación errónea de la potencia de la córnea por parte de la queratometría. La corrección de estos dos factores permitirá realizar un cálculo correcto en estos ojos. De ahí la motivación para realizar una búsqueda actualizadas de los últimos diez años de diversos artículos publicados, con el objetivo de describir los principios para el cálculo de la lente intraocular tras cirugía refractiva corneal.

    Background and purpose: As there are few studies examining the impact of radiotherapy on sexuality, we assessed the effect of radiotherapy for carcinoma of the cervix on sexual health and the ability of the LENT system to assess sexual function. Materials and methods: Using the vagina and sexual dysfunction scales of the LENT SOMA scales, subjective scores were measured prospectively before initiation of radiotherapy for 89 women, and at the following times after the start of treatment: 21, 70, 200, 400, 600 and 800 days. Results: There was considerable variation in pre-radiotherapy scores that was not related to disease stage (P=0.054), but was related to patient age (P=0.037, for the average vagina scores and P=0.039 for the maximum vagina scores) The scores were influenced by prior surgery (P<0.0005 for maximum and average vagina scores, P=0.042 average and 0.017 maximum sexual dysfunction scores). For 48 patients for whom data were available at the first three time points, the vagina scores decreased significantly by 70 days compared to pre-radiotherapy scores, but not for sexual dysfunction. There was heterogeneity in the pattern of changes of scores over time: for some women there was no change in vagina subsection score, some increased, and some decreased. Conclusions: The work has shown variation both in pre-treatment sexual function and in the pattern of changes seen following radiotherapy. Our questionnaire proved useful to score subjective sexual and vaginal problems as given in the LENT subjective scales. Further study is needed to assess the effectiveness of the scales in assessing late effects

    Full Text Available The objective of the present study is to determine the likelihood of injured or poisoned patients in special populations, such as those patients that are elderly and self-injurious, being seen within an emergency department’s triage nurse assigned urgency. Data from the National Hospital Ambulatory Medical Care Survey (2007 was utilized in this study. Multi-level models and multivariate linear regression models were used; patient age, sex, reported pain levels, wait time, and injury type were examined as potential predictors of being seen within assigned urgency. From a random sample across all US Emergency Departments, 5616 patients nested in 312 hospital emergency departments were included into the study. Typically, approximately 1 in 5 emergency department patients were not seen within their triage nurse assigned urgencies. The typical patient in the average hospital had an 81% likelihood of being seen within their assigned urgency. P atients who were oldest [odds ratio (OR=0.0990] and had self-inflicted injuries (vs assault OR=1.246 and OR=1.596 had the least likelihood to be seen within their assigned urgencies. As actual wait-time increased for patients, they were less likely to be seen within their assigned urgencies. The most powerful predictors of the study’s outcome were injury type and age, indicating that patients from special populations such as the elderly or those with injuries resulting from deliberate self-harm are less likely to be actually priority patients independent of triage nurse assigned urgencies.

    A recent study demonstrated improvement in nocturnal urgency in patients with overactive bladder when treated with fesoterodine. In the current study we aimed to determine which bladder diary parameters predict the response to fesoterodine in these patients. Patients with nocturnal urgency completed a 2-week, single-blind placebo run-in followed by 1:1 double-blind randomization to 12 weeks of fesoterodine or placebo. We analyzed bladder diary parameter changes from baseline to week 12, including the actual number of night voids (total number of nocturia episodes), maximum voided volume, nocturnal bladder capacity, Nocturnal Bladder Capacity Index (NBCi) (actual number of night voids - nocturnal urine volume/maximum voided volume - 1), nocturnal urine volume, the nocturia index (nocturnal urine volume/maximum voided volume) and the nocturnal polyuria index (nocturnal urine volume/24-hour volume). Additionally, we analyzed OAB-q (Overactive Bladder Questionnaire) changes. There was a linear relationship between the likelihood of being a responder for NBCi and the nocturia index. Responders had a significant decrease in nocturnal urine volume relative to baseline (-181.7 ml, p overactive bladder syndrome and low nocturnal bladder capacity with a mismatch between nocturnal urine production and bladder capacity may benefit from fesoterodine. Symptom improvement appears to be mediated by increases in typical rather than maximum nocturnal voided volumes. Symptom improvement was associated with improved quality of life.

    attempt to manage urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence. The device was originally developed to manage urinary urge incontinence; however, it has also been used in patients with urgency-frequency, urinary retention, and fecal incontinence. SNS is intended for patients who are refractory to behaviour, drug, and/or interventional therapy. There are 2 phases in the SNS process: first, patients must undergo a test stimulation phase to determine if they respond to sacral nerve stimulation. If there is a 50% or greater improvement in voiding function, then the patient is considered a candidate for the next phase, implantation. The standard Medical Advisory Secretariat search strategy was used to locate international health technology assessments and English-language journal articles published from 2000 to November 2004. The Medical Advisory Secretariat also conducted Internet searches of Medscape (1) and the manufacturer's website (2) to identify product information and recent reports on trials that were unpublished but that were presented at international conferences. In addition, the Web site Current Controlled Trials (3) was searched for ongoing randomized controlled trials (RCTs) investigating the role of sacral nerve stimulation in the management of voiding conditions. Four health technology assessments were found that reviewed SNS in patients with urge incontinence, urgency-frequency, and/or urinary retention. One assessment was found that reviewed SNS in patients with fecal incontinence. The assessments consistently reported that SNS was an effective technology in managing these voiding conditions in patients who did not respond to drug or behaviour therapy. They also reported that there was a substantial complication profile associated with SNS. Complication rates ranged from 33% to 50%. However, none of the assessments reported that they found any incidences of permanent injury or death associated with the device. The

A úlcera de córnea bacteriana é a complicação mais temida em usuários de lente e pode ter relação com vários fatores tais como higiene, conservação e principalmente o uso prolongado. Objetivo: Descrever um caso de úlcera bilateral por Pseudomonas em um paciente usuário de lentes descartáveis, evidenciando e discutindo a importância do exame prévio, orientação e seguimento adequados, bem como ressaltando que por ser descartável a lente não é isenta de complicações graves. Relato do caso: Um estudante de 17 anos, usando lentes descartáveis há 6 meses, sem exame ou prescrição médica, nos procurou queixando-se de dor em OE no qual observou-se úlcera corneana infiltrada na meia periferia. Foi colhido material e iniciado tratamento com colírios fortificados. Após 8 horas, retornou referindo agora dor em OD, tendo sido observada ceratite difusa com secreção mucopurulenta. A conduta foi a mesma. Os exames revelaram Pseudomonas em ambos os olhos e o quadro regrediu sem seqüelas após uma semana de tratamento. Discussão: O autor discute os principais fatores envolvidos com o aparecimento de ceratite infecciosa em usuários de lentes de contato, lembrando que as lentes descartáveis, apesar da sua aparente simplicidade também estão relacionadas com este grave quadro. Ressalta ainda que o uso prolongado é considerado um dos seus principais fatores de risco. O relato de um caso de ceratite bilateral serve de alerta para o uso deste tipo de lente sem a devida orientação e acompanhamento.Introduction: Although the use of contact lenses is appa-rently very simple, it is necessary to obey criteria for their correct use, conservation and disposal.

    We investigated whether parental expressed emotion (criticism and emotional overinvolvement) is related to children's emotional eating and whether this relationship is mediated by children's negative urgency. One hundred children, aged 8 to 13 years, either healthy or have binge-eating disorder and/or attention-deficit/hyperactivity disorder, completed the questionnaires, along with their parents. Parental criticism and, to a lesser extent, parental emotional overinvolvement were both positively related to children's emotional eating, and this relationship was mediated by children's negative urgency. Further exploratory analyses revealed that the mediating role of children's negative urgency in the relationship between parental criticism and children's emotional eating was pronounced in the clinical group of children with binge-eating disorder and attention-deficit/hyperactivity disorder but almost absent in the healthy control group.

    Theoretical models of binge eating and eating disorders include both transdiagnostic and eating disorder-specific risk factors. Negative urgency (i.e., the tendency to act impulsively when distressed) is a critical transdiagnostic risk factor for binge eating, but limited research has examined interactions between negative urgency and disorder-specific variables. Investigating these interactions can help identify the circumstances under which negative urgency is most strongly associated with binge eating. We examined whether prominent risk factors (i.e., appearance pressures, thin-ideal internalization, body dissatisfaction, dietary restraint) specified in well-established etiologic models of eating disorders moderate negative urgency-binge eating associations. Further, we investigated whether phenotypic moderation effects were due to genetic and/or environmental associations between negative urgency and binge eating. Participants were 988 female twins aged 11-25 years from the Michigan State University Twin Registry. Appearance pressures, thin-ideal internalization, and body dissatisfaction, but not dietary restraint, significantly moderated negative urgency-binge eating associations, with high levels of these risk factors and high negative urgency associated with the greatest binge eating. Twin moderation models revealed that genetic, but not environmental, sharing between negative urgency and binge eating was enhanced at higher levels of these eating disorder-specific variables. Future longitudinal research should investigate whether eating disorder risk factors shape genetic influences on negative urgency into manifesting as binge eating.

    In use of their attributions, granted by the Regulation Law of the 27 Constitutional Article in Nuclear Matter, the National Commission of Nuclear Safety and Safeguards (CNSNS) it has taken charge to the authors the Politics' s elaboration and Guide of Application of Urgency measures and Administrative Sanctions (PGAMASA) with the double objective of discouraging the licensees, contractors and employees of incurring in nonfulfillment or violations to the regulator mark and of encouraging them to be attentive to the prompt identification and the immediate and appropriate correction of the violations and nonfulfillment. The present article presents the legal mark that confers the CNSNS the attributions to implant a PGAMASA and it exposes the more important elements that conform it. The urgency measures and administrative sanctions are defined, the approaches to determine the level of graveness of a violation or nonfulfillment and it is related the application process of urgency measures and administrative sanctions are presented. Like this among the urgency measures they stand out figures like the Notifications of Violation and the Regulatory Orders by their versatility and use potentiality. The PGAMASA has a basically dissuasive character and its last purpose it is to strengthen the actions that the CNSNS carries out in the fulfillment of its functions to maintain the safety standards in the operation of the nuclear facilities.

    Full Text Available Abstract Background Prioritization of waiting lists for elective surgery represents a major issue in public systems in view of the fact that patients often suffer from consequences of long waiting times. In addition, administrative and standardized data on waiting lists are generally lacking in Italy, where no detailed national reports are available. This is true although since 2002 the National Government has defined implicit Urgency-Related Groups (URGs associated with Maximum Time Before Treatment (MTBT, similar to the Australian classification. The aim of this paper is to propose a model to manage waiting lists and prioritize admissions to elective surgery. Methods In 2001, the Italian Ministry of Health funded the Surgical Waiting List Info System (SWALIS project, with the aim of experimenting solutions for managing elective surgery waiting lists. The project was split into two phases. In the first project phase, ten surgical units in the largest hospital of the Liguria Region were involved in the design of a pre-admission process model. The model was embedded in a Web based software, adopting Italian URGs with minor modifications. The SWALIS pre-admission process was based on the following steps: 1 urgency assessment into URGs; 2 correspondent assignment of a pre-set MTBT; 3 real time prioritization of every referral on the list, according to urgency and waiting time. In the second project phase a prospective descriptive study was performed, when a single general surgery unit was selected as the deployment and test bed, managing all registrations from March 2004 to March 2007 (1809 ordinary and 597 day cases. From August 2005, once the SWALIS model had been modified, waiting lists were monitored and analyzed, measuring the impact of the model by a set of performance indexes (average waiting time, length of the waiting list and Appropriate Performance Index (API. Results The SWALIS pre-admission model was used for all registrations in the

    The objective of this study was to examine the strength and direction of the association between urinary symptoms and both poor quality sleep and daytime sleepiness among women with urgency urinary incontinence. A planned secondary analysis of baseline characteristics of participants in a multicenter, double-blinded, 12-week randomized controlled trial of pharmacologic therapy for urgency-predominant urinary incontinence in ambulatory women self-diagnosed by the 3 Incontinence Questions was performed. Urinary symptoms were assessed by 3-day voiding diaries. Quality of sleep was assessed using the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness using the Epworth Sleepiness Scale. Of the 640 participants, mean (SD) age was 56 (±14) years and 68% were white. Participants reported an average of 3.9 (±3.0) urgency incontinence episodes per day and 1.3 (±1.3) episodes of nocturia per night. At baseline, 57% had poor sleep quality (PSQI score, >5) and 17% reported daytime sleepiness (Epworth Sleepiness Scale score, >10). Most women (69%) did not use sleeping medication during the prior month, whereas 13% reported use of sleeping medication 3 or more times per week. An increase in total daily incontinence episodes, total daily urgency incontinence episodes, total daily micturitions, and moderate to severe urge sensations were all associated with higher self-report of poor sleep quality according to the PSQI (all P ≤ 0.01). Higher scores on the Bother Scale and the Health-Related Quality of Life for overactive bladder on the Overactive Bladder Questionnaire were similarly associated with higher rates of poor sleep quality (both P ≤ 0.01). In subgroup analysis of those who took sleeping medications less than twice a week, there was still a significant relationship between incontinence measures and quality of sleep as measured by the PSQI. In multivariable analyses, greater frequency of nighttime urgency incontinence was associated with poor sleep quality

    Objective Macrovascular diseases and urgency incontinence are common among Japanese patients with type 2 diabetes mellitus. However, little evidence exists regarding the association between stroke and urgency incontinence among patients with type 2 diabetes mellitus. We examined the associations between macrovascular complications and urgency incontinence among Japanese patients with type 2 diabetes mellitus. Methods The study subjects were 818 Japanese patients with type 2 diabetes mellitus. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate?" We adjusted our analyses for sex, age, body mass index, duration of type 2 diabetes, current smoking, current drinking, hypertension, dyslipidemia, glycated hemoglobin, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy. Results The prevalence of urgency incontinence was 9.2%. Stroke was independently positively associated with urgency incontinence, with an adjusted odds ratio of 2.34 (95% confidence interval: 1.03-4.95). The associations between ischemic heart disease or peripheral artery disease and the prevalence of urgency incontinence were not significant. Conclusion In Japanese patients with type 2 diabetes mellitus, stroke, but not ischemic heart diseases or peripheral artery disease, was independently positively associated with urgency incontinence.

    2001-12-01

    The effectiveness of manual physical therapy was evaluated in patients with interstitial cystitis and the urethral syndrome, that is urgency-frequency with or without pelvic pain. The rationale was based on the hypothesis that pelvic floor myofascial trigger points are not only a source of pain and voiding symptoms, but also a trigger for neurogenic bladder inflammation via antidromic reflexes. From September 1995 to November 2000, 45 women and 7 men, including 10 with interstitial cystitis and 42 with the urgency-frequency syndrome, underwent manual physical therapy to the pelvic floor for 1 to 2 visits weekly for 8 to 12 weeks. Results were determined by patient completed symptom score sheets indicating the rate of improvement according to outcome parameters, including 25% to 50%-mild, 51% to 75%-moderate, 76% to 99%-marked and 100%-complete resolution. In 10 cases these subjective results were confirmed by measuring resting pelvic floor tension by electromyography before and after the treatment course. Of the 42 patients with the urgency-frequency syndrome with or without pain 35 (83%) had moderate to marked improvement or complete resolution, while 7 of the 10 (70%) with interstitial cystitis had moderate to marked improvement. The mean duration of symptoms before treatment in those with interstitial cystitis and the urgency-frequency syndrome was 14 (median 12) and 6 years (median 2.5), respectively. In patients with no symptoms or brief, low intensity flares mean followup was 1.5 years. In 10 patients who underwent electromyography mean resting pelvic floor tension decreased from 9.73 to 3.61 microV., which was a 65% improvement. Pelvic floor manual therapy for decreasing pelvic floor hypertonus effectively ameliorates the symptoms of the urgency/frequency syndrome and interstitial cystitis.

    Full Text Available Several studies have indicated an increased resistance of microorganisms resulting from the widespread use of antimicrobial agents. However, few data are available in the dental literature. The aim of this study was to conduct a survey on the patterns of patient usage of antimicrobial prescriptions agents by dentists. A retrospective cross-sectional study was based on the medical records of 223 patients who sought treatment at the Urgency Service, from a Dental School in the South of Brazil, from March 2009 to March 2011. A specific data sheet was used, with questions regarding: patient age and gender; the main complaint; medications used prior to the service; final diagnosis; proposed dental treatment (including prescription medications; and characteristics of the final prescription. Descriptive and inferential statistics were obtained. There was a high frequency of antibiotic use prior to attendance by young patients (Fisher’s exact test, p < 0.05. Toothache of endodontic origin was the most frequent patient complaint (72.6%. Endodontic procedures were the measures most frequently adopted to treat the pain (31.2%. The frequency of patient use of antimicrobials prior to the appointment was 14.3%. According to patient records, 83.9% had no systemic drug prescription after receiving urgency treatment. There were few antimicrobial prescriptions after the urgency treatment. The most frequently prescribed agents were amoxicillin, chlorhexidine, and metronidazole. Local measures were more frequently used than systemic approaches to treat urgencies of dental origin. Antimicrobial agents were not frequently prescribed as adjunctives to local administered at the urgency service.

    Full Text Available Fundamentos: El elevado número de personas que trabajando con ordenador utiliza lentes de contacto plantea la cuestión sobre si la suma de estos dos factores de riesgo para la salud visual puede originar un agravamiento del Síndrome Visual Informático. El objetivo de esta revisión es sintetizar el conocimiento científico sobre las alteraciones oculares y visuales relacionadas con la exposición a ordenador en usuarios de lentes de contacto. Métodos: Revisión de artículos científicos (2003-2013 en español e inglés, realizando una búsqueda bibliográfica, en Medline a través de PubMed y en Scopus. Resultados: La búsqueda inicial aportó 114 trabajos, después de aplicar criterios de inclusión/exclusión se incluyeron seis artículos. Todos ellos ponen de manifiesto que las alteraciones al utilizar el ordenador son más frecuentes en las personas usuarias de lentes de contacto, con prevalencias que oscilan de 95,0% al 16,9% que en las que no utilizan lentes de contacto, cuya prevalencia va del 57,5% al 9,9% y con una probabilidad cuatro veces mayor de padecer ojo seco [OR: 4,07 (IC 95%: 3,52-4,71]. Conclusiones: Las personas usuarias de ordenador padecen más alteraciones oculares y visuales cuando además son usuarias de lentes de contacto, pero los estudios son escasos y poco contundentes. Se precisan nuevas investigaciones que analicen la influencia según los tipos de lentes y sus condiciones de uso, tanto en la sintomatología como en la calidad de la lágrima y la superficie ocular. Las lentes de hidrogel de silicona son las que se asocian a mayor confort.

    To investigate the extent to which cues are reported to be associated with urinary urgency incontinence and urinary urgency. Descriptive and correlational study comparing 2 groups. An online questionnaire assessing the extent to which 19 environmental, 3 mood, 3 cognitive, 3 stress incontinence, 1 bladder volume cue, and 3 unlikely cues were associated with episodes of urinary urgency incontinence and urgency was administered. Three hundred six participants were randomly drawn from a panel of respondents maintained by Zoomerang, Inc. Approximately half (n = 150) had self-reported diagnoses of overactive bladder syndrome (OAB) and half did not. Cue ratings were compared between persons with and without OAB and between likely and unlikely cues. The most frequently reported environmental cues were "On the way to the bathroom" and "Arrival at home/opening front door"; these cues were reported by both groups. Respondents with and without OAB showed significant differences in the mean number of cues associated with urinary urgency incontinence and with urinary urgency; persons with OAB were always higher. Significant differences between persons with and without OAB were found for 28 of 32 cues associated with incontinence and 25 of 32 cues associated with urinary urgency. To investigate response bias, within-subjects analyses compared mean responses to the 3 unlikely cues to means of all other cues. Analyses revealed that scores for unlikely cues were significantly lower than scores for likely cues. Cues associated with urgency incontinence and urgency were frequently reported by both groups. However, responding to cues was significantly more frequent among those who had been diagnosed with OAB. These findings may have implications for the diagnosis and treatment of urinary urgency incontinence.

    Full Text Available Con el surgimiento y el desarrollo de la cirugía refractiva corneal se han podido corregir quirúrgicamente a millones de pacientes con defectos refractivos. Con el cursar de los años comienza a opacarse fisiológicamente el cristalino, y disminuye la agudeza visual en estos pacientes a quienes se les modificó la curvatura corneal. Ante la necesidad de remover el cristalino y de calcular una lente intraocular de potencia adecuada para conseguir la emetropía, surge un nuevo reto a la Oftalmología. El cálculo de la lente intraocular en pacientes con cirugía refractiva corneal es mucho más complejo, pues además de tener longitudes axiales extremas, se añaden factores por la intervención previa que alteran la predictibilidad del resultado visual, con la aplicación de las fórmulas de cálculo de lente intraocular existentes. Se han descrito varios métodos que permiten determinar correctamente la potencia de la lente a implantar, dependiendo de los datos de los que se dispongan; de ahí la motivación para realizar una revisión de diferentes publicaciones con el propósito de describir los principales métodos empleados para realizar el cálculo de la lente intraocular en estos pacientes. Se utilizó la plataforma Infomed, específicamente la Biblioteca Virtual de Salud, con todos sus buscadores.

    Full Text Available After a course of Basic Lift Support, Nurses and Doctors skills retention decline if not used over time. Studies have suggest that methods need to be evaluated and refined to improve practice. A more detailed assessment toll is needed to determine the effectiveness of an educational intervention in providing the best skill acquisition and retention attainable. This review of literature examines factors that enhance retention of knowledge and skill during and after resuscitation training. In order to identify educational strategies that will optimize current practices and suggest the application of the experiential theory of learning to Basic Life Support. The review was undertaken using PUBMED, EMBASE and EBM Reviews – Cochrane Central Register of Controlled Trials. Additional references were also reviewed from the bibliographies and from citation searches on key articles. Those published that identified strategies to enhance the acquisition or retention of cardiopulmonary resuscitation skill and knowledge were included in the review. Review showed that templates should be introduced for research or evaluation of educational interventions designed to improve resuscitation performance. Resuscitation training should be based on in-hospital scenarios and current evidence-based guidelines. Video instruction and new technologies has been shown to improve competence in resuscitation. The research findings suggest the need for an evaluation of the use and effects of cognitive instructional strategies and new technologies in CPR training courses on transfer ok skill and knowledge to practice.

    According to power plant operators, it was said that they could quite well recognize off-normal situations from an incipient stage and also anticipate the possibility of upcoming trips in case of skilled operators, even though it is difficult to clarify the cause of the off-normal situation. From the interview, we could assure the feasibility of two assumptions for the diagnosis of off-normal conditions: One is that we can predict whether an accidental shutdown happens or not if we observe the early stage when an off-normal starts to grow. The other is the observation at the early stage can provide the remaining time to a trip as well as the cause of such an off-normal situation. For this purpose, the development of on-line monitoring systems using various data processing techniques in nuclear power plants (NPPs) has been the subject of increasing attention and becomes important contributor to improve performance and economics. Many of studies have suggested the diagnostic methodologies. One of representative methods was to use the distance discrimination as a similarity measure, for example, such as the Euclidean distance. A variety of artificial intelligence techniques such as a neural network have been developed as well. In addition, some of these methodologies were to reduce the data dimensions for more effectively work. While sharing the same motivation with the previous achievements, this study proposed non-parametric pattern matching techniques to reduce the uncertainty in pursuance of selection of models and modeling processes. This could be characterized by the following two aspects: First, for overcoming considering only a few typical scenarios in the most of the studies, this study is getting the entire sets of off-normal situations which are anticipated in NPPs, which are created by a full-scope simulator. Second, many of the existing researches adopted the process of forming a diagnosis model which is so-called a training technique or a parametric

    Overactive Bladder (OAB) is a clinical condition characterized by symptoms reported by patients. Therefore, measurement instruments based on reported information are important for understanding its impact and treatment benefits. The aim of this study was to translate, culturally adapt and validate the Urgency Questionnaire (UQ) in Portuguese. Initially, the UQ was translated and culturally adapted to Portuguese. Sixty-three volunteers were enrolled in the study and were interviewed for responding the Portuguese version of the UQ and the validated Portuguese version of the Overactive Bladder Questionnaire short-form (OABq-SF), used as the gold standard measurement for the validation process. Psychometric properties such as criterion validity, stability, and reliability were tested. Forty-six subjects were included in the symptomatic group (presence of "urgency"), and seventeen were included in the asymptomatic group (control group). There was difference between symptomatic and asymptomatic subjects on all of the subscales (p≤0.001). The UQ subscales correlated with the OABq-SF subscales (p≤0.01), except the subscale "time to control urgency" and the item "impact" from the visual analog scales (VAS). However, these scales correlated with the OABq-SF - Symptom Bother Scale. The UQ subscales demonstrated stability over time (pPortuguese version of the UQ proved to be a valid tool for the evaluation of OAB in individuals whose native language is Portuguese.

  6. Examining the role of emotion in suicidality: negative urgency as an amplifier of the relationship between components of the interpersonal-psychological theory of suicidal behavior and lifetime number of suicide attempts.

    2011-03-01

    Joiner's (2005) interpersonal-psychological theory of suicidal behavior posits that an individual must exhibit elevations on three variables--perceived burdensomeness, thwarted belongingness, and the acquired capability for suicide--in order to enact lethal self-harm. Thus far, however, no research has examined the role of emotion in this process or whether the interaction of these three variables is more problematic for certain populations than for others. We sought to address these voids by examining the role of negative urgency as an amplifier of the relationship between the components of the theory and lifetime number of suicide attempts. Results indicated that the four-way interaction of negative urgency and the three components of the theory predicted lifetime number of suicide attempts, controlling for depression symptoms and sex. Additionally, the three-way interaction of the theory components significantly predicted lifetime number of suicide attempts in the full sample. Furthermore, for individuals with negative urgency scores at or above the median, the three-way interaction of the theory components significantly predicted lifetime number of suicide attempts whereas, for individuals with negative urgency scores below the median, the interaction was non-significant. These findings indicate that, although elevations on the three components of the theory may be dangerous for anyone, this is particularly true for individuals exhibiting high levels of negative urgency, as they might be more likely to quickly develop suicidal ideation and resort to painful self-harming behaviors while experiencing negative affective states.

Algunos de estos productos personalizados, como es el caso de las gafas deportivas con lentes coloreadas, ofrecen prestaciones que aseguran un mejor confort y/o rendimiento deportivo en determinados contextos. Sin embargo, la base científica que apoya el beneficio de dichos artículos es desconocida. Así, el propósito de este estudio es realizar una revisión del trabajo científico publicado que explique el posible beneficio que puede suponer el uso de un tipo de coloreado u otro en las lentes de las gafas deportivas. Para ello, se ha llevado a cabo una revisión bibliográfica centrada en aspectos de confort y de rendimiento visual en la práctica deportiva, a través de bases documentales científicas, de páginas web y de normativa referente al uso de lentes deportivas. La principal conclusión que se puede extraer es que el estado del arte ofrece una limitada base científica para soportar los productos existentes en el mercado, así como para proponer lentes de color para deportes concretos. Queda establecido que a través de determinados filtros coloreados puedan mejorarse los tiempos de reacción y la habilidad visual, pero en caso de abordar esta línea de I+D, sería incluso necesario poner a punto métodos de medida adecuados.

    2010-01-01

    Purpose: The patient's role in toxicity reporting is increasingly acknowledged but requires the adaptation and validation of toxicity reporting instruments for patient use as most toxicity scales are designed for physician use. Recording of radiotherapy related late toxicity is important and needs to be improved. A patient-scored symptom questionnaire of late treatment effects using LENT-SOMA was compared with a recognised quality of life tool (EORTC QLQ-C30/H and N35). Materials/methods: LENT-SOMA and EORTC QLQ-C30 patient questionnaires were prospectively completed by 220 head and neck cancer patients over 3 years and 72 completed EORTC QLQ-H and N35 questionnaires at 2 years post-radiotherapy. Results: Endpoints common to both questionnaires (pain, swallowing, dental pain, dry mouth, opening mouth, analgesics) were matched. Spearman rank correlation coefficients with ρ > 0.6 (P < 0.001) were obtained for all 'matched' scales except for analgesics scale, ρ = 0.267 (P < 0.05). There was good agreement between LENT-SOMA and EORTC QLQ-H and N35 except for analgesic endpoints. Global quality of life scores correlated negatively with average LENT-SOMA scores (P < 0.001). Significant differences in average LENT-SOMA scores between treatment modalities were found. The LENT-SOMA questionnaire has demonstrated a high Cronbach's α value (0.786) indicating good reliability. Conclusions: LENT-SOMA patient questionnaire results agreed well with those from the EORTC QLQ-H and N35 questionnaire for toxicity items where they could be compared explicitly, particularly for subjective endpoints. Patient-reported late toxicity had a negative impact on quality of life. The LENT-SOMA patient questionnaire is both reliable and sensitive to differences between patients treated with different modalities. A patient-based questionnaire is an important contributor to capturing late radiotherapy effects.

    We compared the efficacy of electrical pudendal nerve stimulation vs transvaginal electrical stimulation to treat female idiopathic urgency urinary incontinence. A total of 120 female patients with idiopathic urgency urinary incontinence refractory to medication were randomized at a ratio of 2:1 to group 1 of 80 patients and group 2 of 40. Groups 1 and 2 were treated with electrical pudendal nerve stimulation and transvaginal electrical stimulation, respectively. To perform electrical pudendal nerve stimulation long acupuncture needles were deeply inserted into 4 sacrococcygeal points and electrified to stimulate pudendal nerves. Outcome measures were the 24-hour pad test and a questionnaire to measure the severity of symptoms and quality of life in women with urgency urinary incontinence. The median severity of symptoms and quality of life score on the urgency urinary incontinence questionnaire (urgency urinary incontinence total score) was 13 (range 7 to 18.75) in group 1 and 11 (range 8 to 16) in group 2 before treatment, which decreased to 2 (range 0 to 6.75) in group 1 and 6.5 (range 3.25 to 10.75) in group 2 (both p Electrical pudendal nerve stimulation is more effective than transvaginal electrical stimulation in treating drug refractory, female idiopathic urgency urinary incontinence.

    Diabetes was significantly positively associated with urgency incontinence in several epidemiological studies. We examine the association between diabetic neuropathy, which we defined based on neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception, and urgency incontinence among Japanese patients with type 2 diabetes mellitus. Study subjects were 742 Japanese patients with type 2 diabetes mellitus, aged 19-70 years, who had undergone blood tests at our institutions. A self-administered questionnaire was used to collect information on the variables under study. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate ?". Diabetic neuropathy was diagnosed if the patients showed two or more of the following three characteristics: neuropathic symptoms, the absence of the Achilles reflex, and/or abnormal vibration perception. Adjustment was made for sex, age, body mass index, duration of type 2 diabetes mellitus, current smoking, hypertension, dyslipidemia, glycated hemoglobin, stroke, coronary artery disease, insulin therapy, diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy. The prevalence of urgency incontinence was 8.6%. Diabetic neuropathy was independently positively associated with urgency incontinence: the adjusted OR was 2.20 (95%CI: 1.16-4.36).

    Although the personality trait of urgency has been linked to problem gambling, less is known about psychological mechanisms that mediate the relationship between urgency and problem gambling. One individual variable of potential relevance to impulsivity and addictive disorders is age. The aims of this study were to examine: (i) a theoretical model associating urgency and gambling problems, (ii) the mediating effects of decision-making processes (operationalized as preference for small/immediate rewards and lower levels of deliberative decision-making); and (iii) age differences in these relationships. Participants comprised 986 students (64% male; mean age=19.51 years; SD=2.30) divided into three groups: 16-17 years, 18-21 years, and 22-25 years. All participants completed measures of urgency, problem gambling, and a delay-discounting questionnaire involving choices between a smaller amount of money received immediately and a larger amount of money received later. Participants were also asked to reflect on their decision-making process. Compared to those aged 16-17 years and 22-25 years, participants aged 18-21 years had a higher level of gambling problems and decreased scores on lower levels of deliberative decision-making. Higher levels of urgency were associated with higher levels of gambling problems. The association was mediated by a lower level of deliberative decision-making and preference for an immediate/small reward. A distinct pathway was observed for lower levels of deliberative decision-making. Young people who tend to act rashly in response to extreme moods, had lower levels of deliberative decision-making, that in turn were positively related to gambling problems. This study highlights unique decision-making pathways through which urgency trait may operate, suggesting that those developing prevention and/or treatment strategies may want to consider the model's variables, including urgency, delay discounting, and deliberative decision

    Full Text Available Background and Aims. This report demonstrates the utility of a pudendal nerve block by pulsed radiofrequency ablation (RFA for the treatment of male pelvic pain and urinary urgency and hesitancy. Methods. The patient is an 86-year-old gentleman with a 30-year history of urinary hesitancy and urgency. The patient also had pain in the area of the perineum but considered it a secondary issue. The patient was seen by a number of specialists, tried various medications, and underwent a variety of procedures to no avail. Therefore, the patient underwent a pulsed RFA of the pudendal nerve. Results. The patient underwent a pulsed RFA of the pudendal nerve; the patient reported marked improvement in his pelvic pain as well as a drastic reduction in his urinary urgency and hesitancy. Conclusion. Urinary urgency and hesitancy and male pelvic pain are some of the most common symptoms affecting men. Pudendal nerve block by pulsed RFA is an effective treatment of pelvic pain. It may also hold some therapeutic value in the treatment of urinary urgency and hesitancy as our case demonstrated. Further studies are needed to help clarify both the anatomy of the pelvis as well as if pudendal blocks are effective in treating more than pelvic pain.

    Emergency room (ER) use is increasing in several countries. Variability in the proportion of non-urgent ER visits was found to range from 5 to 90 % (median 32 %). Non-urgent emergency visits are considered an inappropriate and inefficient use of the health-care system because they may lead to higher expenses, crowding, treatment delays, and loss of continuity of health care provided by a general practitioner. Urgency levels of doctor-walk-in patient encounters were assessed based on their region of origin in a diverse Norwegian population. An anonymous, multilingual questionnaire was distributed to all walk-in patients at a general emergency outpatient clinic in Oslo during two weeks in September 2009. We analysed demographic data, patient-doctor assessments of the level of urgency, and the results of the consultation. We used descriptive statistics to obtain frequencies with 95 % confidence interval (CI) for assessed levels of urgency and outcomes. Concordance between the patients' and doctors' assessments was analysed using a Kendall tau-b test. We used binary logistic regression modelling to quantify associations of explanatory variables and outcomes according to urgency level assessments. The analysis included 1821 walk-in patients. Twenty-four per cent of the patients considered their emergency consultation to be non-urgent, while the doctors considered 64 % of encounters to be non-urgent. The concordance between the assessments by the patient and by their doctor was positive but low, with a Kendall tau-b coefficient of 0.202 (p < 0.001). Adjusted logistic regression analysis showed that patients from Eastern Europe (odds ratio (OR) = 3.04; 95 % CI 1.60-5.78), Asia and Turkey (OR = 4.08; 95 % CI 2.43-6.84), and Africa (OR = 8.47; 95 % CI 3.87-18.5) reported significantly higher urgency levels compared with Norwegians. The doctors reported no significant difference in assessment of urgency based on the patient's region of origin, except

    Purpose: To evaluate the long-term toxicity after breast-conserving therapy in women with early-stage breast cancer. Methods and Materials: Late toxicity according to the late effects of normal tissue-subjective, objective, management, and analytic (LENT-SOMA) criteria and cosmetic outcome (graded by physicians) were evaluated in 590 of 2943 women with early-stage breast cancer who were irradiated between 1983 and 1995 using the following fractionation schedules: group A, 1983-1987, 2.5 Gy 4x/wk to 60 Gy; group B, 1988-1993, 2.5 Gy 4x/wk to 55 Gy, group C, 1994-1995, 2.0 Gy 5x/wk to 55 Gy. Results: LENT-SOMA Grade 3-4 toxicity was observed as follows: group A (median follow-up 171 months; range 154-222 months), fibrosis 16% (7 of 45), telangiectasia 18% (8 of 45), and atrophy 4% (2 of 45); group B (median follow-up 113 months; range 78-164 months), pain 2% (8 of 345), fibrosis 10% (34 of 345), telangiectasia 10% (33 of 345), arm edema 1% (2 of 345), and atrophy 8% (27 of 345); and group C (median follow-up 75 months, range 51-96 months, n = 200), occurrence of Grade 3-4 late morbidity ≤2%. The cosmetic outcome was very good to acceptable in 78% (35 of 45) of patients in group A, 83% (286 of 345) in group B, and 94% (187 of 200) in group C. Conclusion: In our population, the long-term side effects after breast-conserving therapy were not rare, but were mainly asymptomatic. The LENT-SOMA breast module is a practical tool to assess radiation-induced long-term toxicity

    In our clinical practice we encountered urgency-frequency syndrome in female patients. Only in the 3.6% is possible to diagnose a typical interstitial cystitis (IC). In the 63.6% we observed only local trigonal squamous metaplasia (leucoplasia), it could be considered a paraphysiological condition present in 50-70% of fertile women, its rigid, not impermeable epithelium may offer an aethiological hypotesis for the dysuric syndrome. In the treatment of this lesion by endoscopic infiltration we had syntomatological results with 47.8% of patients even if only for a short period (one-two years). This treatment is simple and can be repeated, if the patient is responsive. We noticed that the results did not change even if we used different drugs probably due to the role of a physical detachment of leucoplasia from bladder trigon.

  4. Time-Lag in Responses of Birds to Atlantic Forest Fragmentation: Restoration Opportunity and Urgency.

    Directory of Open Access Journals (Sweden)

    Alexandre Uezu

    Full Text Available There are few opportunities to evaluate the relative importance of landscape structure and dynamics upon biodiversity, especially in highly fragmented tropical landscapes. Conservation strategies and species risk evaluations often rely exclusively on current aspects of landscape structure, although such limited assumptions are known to be misleading when time-lag responses occur. By relating bird functional-group richness to forest patch size and isolation in ten-year intervals (1956, 1965, 1978, 1984, 1993 and 2003, we revealed that birds with different sensitivity to fragmentation display contrasting responses to landscape dynamics in the Brazilian Atlantic Forest. For non-sensitive groups, there was no time-lag in response: the recent degree of isolation best explains their variation in richness, which likely relates to these species' flexibility to adapt to changes in landscape structure. However, for sensitive bird groups, the 1978 patch area was the best explanatory variable, providing evidence for a 25-year time-lag in response to habitat reduction. Time-lag was more likely in landscapes that encompass large patches, which can support temporarily the presence of some sensitive species, even when habitat cover is relatively low. These landscapes potentially support the most threatened populations and should be priorities for restoration efforts to avoid further species loss. Although time-lags provide an opportunity to counteract the negative consequences of fragmentation, it also reinforces the urgency of restoration actions. Fragmented landscapes will be depleted of biodiversity if landscape structure is only maintained, and not improved. The urgency of restoration action may be even higher in landscapes where habitat loss and fragmentation history is older and where no large fragment remained to act temporarily as a refuge.

As with adults, pediatric patients with HTN can present with hypertensive crises include hypertensive urgency and hypertensive emergencies. However, pediatric blood pressure problems have a greater chance of being from secondary causes of HTN, as opposed to primary HTN, than in adults. Thorough evaluation of a child with a hypertensive emergency includes accurate blood pressure readings, complete and focused symptom history, and appropriate past medical, surgical, and family history. Physical exam should include height, weight, four-limb blood pressures, a general overall examination and especially detailed cardiovascular and neurological examinations, including fundoscopic examination. Initial work-up should typically include electrocardiography, chest X-ray, serum chemistries, complete blood count, and urinalysis. Initial management of hypertensive emergencies generally includes the use of intravenous or oral antihypertensive medications, as well as appropriate, typically outpatient, follow-up. Emergency department goals for hypertensive crises are to (1 safely lower blood pressure, and (2 treat/minimize acute end organ damage, while (3 identifying underlying etiology. Intravenous antihypertensive medications are the treatment modality of choice for hypertensive emergencies with the goal of reducing systolic blood pressure by 25% of the original value over an 8

    The prevalence and economic burden of urgency urinary incontinence (UUI) are difficult to ascertain because of overlap with data on overactive bladder and other types of incontinence. To summarize the evidence on the global prevalence and economic burden of UUI. A PubMed search was performed used the following terms: (urgency urinary incontinence OR urge incontinence OR mixed incontinence OR overactive bladder) AND (burden OR cost OR economic OR prevalence). A similar search was conducted using Embase. English-language articles published from 1991 through 2013 on non-neurogenic UUI were retained. We retained 54 articles (50 studies); 22 large-scale, population-based surveys indicated varying UUI prevalence estimates with ranges of 1.8-30.5% in European populations, 1.7-36.4% in US populations, and 1.5-15.2% in Asian populations, with prevalence dependent on age and gender. Nineteen smaller-scale studies supported these findings. Despite varying methods, 11 studies estimating the costs of UUI worldwide consistently concluded that the economic burden is substantial and will increase markedly as the population ages. In a 2005 multinational study, the annual cost-of-illness estimate for UUI in Canada, Germany, Italy, Spain, Sweden, and the United Kingdom was €7 billion. A US cost-of-illness study reported a total cost of $66 billion in 2007 US dollars. The costs of routine care and nursing home admissions for UUI were major contributors to the cost. UUI affects millions of men and women worldwide. Current evidence demonstrates the substantial economic burden of UUI to patients and society. Worldwide public health and clinical management programs are needed to improve UUI awareness and highlight the need for early diagnosis and management.

    Studies on the burden and comorbidities associated with urgency urinary incontinence (UUI) are difficult to compare, partly because of the evolution of definitions for lower urinary tract symptoms and the various instruments used to assess health-related quality of life (HRQL). This article summarises published evidence on comorbidities and the personal burden associated specifically with UUI to provide clinicians with a clear perspective on the impact of UUI on patients. A PubMed search was conducted using the terms: (urgency urinary incontinence OR urge incontinence OR mixed incontinence OR overactive bladder) AND (burden OR quality of life OR well-being OR depression OR mental health OR sexual health OR comorbid), with limits for English-language articles published between 1991 and 2011. Of 1364 identified articles, data from 70 retained articles indicate that UUI is a bothersome condition that has a marked negative impact on HRQL, with the severity of UUI a predictor of HRQL. UUI is significantly associated with falls in elderly individuals, depression, urinary tract infections, increased body mass index, diabetes and deaths. The burden of UUI appears to be greater than that of stress urinary incontinence or overactive bladder symptoms without UUI. UUI adversely impacts physical and mental health, sexual function and work productivity. UUI is associated with numerous comorbid conditions and inflicts a substantial personal burden on many aspects of patients' lives. Healthcare providers should discuss UUI with patients and be aware of the impact of UUI and its associated comorbidities on patients' lives. © 2013 John Wiley & Sons Ltd.

Suas principais finalidades são: reduzir a dor; proteger a córnea; facilitar e manter a cicatrização epitelial; restaurar a câmara anterior e liberar medicamentos na superfície ocular. Há uma variedade de tipos e materiais, sendo que a escolha depende da doença a ser tratada, tempo de uso e necessidades fisiológicas do olho doente. Doenças como a ceratopatia bolhosa, erosão recorrente do epitélio corneano, olho seco e defeitos epiteliais pós-operatórios, além de várias outras doenças que afetam a superfície ocular podem ser tratadas com a utilização das lentes de contato terapêuticas. Elas não devem ser utilizadas em processos infecciosos ou em pacientes que estão impossibilitados de retornar para acompanhamento regular. A adaptação, controle e manutenção adequados das lentes de contato terapêuticas são fundamentais para prevenir complicações, como: neovascularização corneana, conjuntivite papilar gigante ou ceratite infecciosa. O controle e manutenção foram facilitados com o advento das lentes de contato terapêuticas de silicone-hidrogel.

    We tested a theoretical model concerning the role of attentional bias and negative affect in food consumption that offers important advances. We hypothesized that the effects of negative affect manipulations on food consumption vary as a function of trait levels of negative urgency (NU; tendency to act impulsively when distressed), and attentional bias and that the roles of emotional arousal and negative emotional valence differ and should be studied separately. 190 undergraduate women were randomly assigned to either an anger or neutral mood condition. Women in both conditions completed the Food Stroop, in which the presentation of food and neutral words were counterbalanced. After the task, participants were given the opportunity to eat mandarin oranges and/or chocolate candy while the experimenter was out of the room. The type and quantity of food consumed was counted after the participant departed. As hypothesized, the roles of emotional arousal and valence differed and the effect of the induced emotion was moderated by NU. Women high in NU who experienced emotional arousal were more likely to eat candy and consumed more candy than other women. Emotional valence had no effect on candy consumption. Neither increases in emotional arousal or emotional valence influenced attentional bias to food cues. Attentional bias was also unrelated to food consumption. The impact of negative mood inductions on palatable food consumption appears to operate through emotional arousal and not negative emotional valence, and it may operate primarily for women high in NU.

    To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder. A search was made of the institute's database for all patients diagnosed with overactive bladder over the preceding four years. Children and adolescents under 18 years of age with overactive bladder and no neurological or anatomical alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the presence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify patients with febrile UTI and subsequently determine predictors of this condition. Univariate and multivariate analyses were performed. Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses. These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.

Intravenous antihypertensive medications are the treatment modality of choice for hypertensive emergencies with the goal of reducing systolic blood pressure by 25% of the original value over an 8-hour period.

Exclusion criteria were mainly stress urinary incontinence. Patients underwent one week of subject-controlled, on-demand, dorsal genital nerve stimulation, delivered by a percutaneously placed electrode near the dorsal genital nerve connected to an external stimulator (pulse-rate 20 Hz, pulse-width 300 μs. Patients activated the stimulator when feeling the urge to void and stimulated for 30 s. The amplitude was set at the highest tolerable level. A bladder diary including a severity score of the urgency urinary incontinence episodes/void (scores: 0=none, 1=drops, 2=dashes, 3=soaks and a padtest was kept 3 days prior to, during, and 3 days after the test period. The subjective improvement was also scored.ResultsSeven patients (4 males / 3 females were enrolled, the mean age was 55 years (range 23-73. Six completed the test week. In the remaining patient the electrode migrated and was removed. 5/6 finalized the complete bladder diary, 1/6 recorded only the heavy incontinence episodes (score=3. 4/6 completed the padtest. In all patients who finalized the bladder diary the number of urgency urinary incontinence episodes decreased, in 3/5 with ≥60%. The heavy incontinence episodes (score=3 were resolved in 2/6 patients, and improved ≥ 80% in the other 4. The severity score of the urgency urinary incontinence episodes/void was improved with ≥60% in 3/5 patients. The mean subjective improvement was 73%.

    Full Text Available OBJETIVO: Quantificar e comparar a aderência in vitro das bactérias Staphylococcus epidermidis e Pseudomonas alcaligenes em diferentes tipos de lentes intra-oculares (LIOs. MÉTODOS: Quatorze lentes intra-oculares foram usadas no experimento. Quatro de polimetilmetacrilato (PMMA, quatro de silicone, quatro de hidrogel e duas de acrílico. Oito lentes intra-oculares foram colocadas em oito tubos de ensaio contendo 4 ml de suspensão de Pseudomonas alcaligenes, e seis lentes intra-oculares foram colocadas em seis tubos de ensaio contendo 4 ml de suspensão de Staphylococcus epidermidis. A concentração do caldo utilizada para o teste de aderência foi de 10(8 unidades formadoras de colônias por mililitro (CFU/mL que corresponde a 0,5 na escala de McFarland. As lentes foram incubadas a 37° por duas horas. Após, foram removidas dos caldos e enxaguadas em água destilada estéril por duas vezes. As lentes foram cultivadas em placas de ágar-sangue a 35-37° e evaliadas a cada 24h por um período de 72h. Nas amostras que tiveram crescimento bacteriano, foram contadas as colônias utilizando os métodos convencionais de laboratório. Todos os ensaios foram executados em duplicata. RESULTADOS: A aderência do Staphylococcus epidermidis nas lentes de PMMA foi menor se comparada com as de silicone e de hidrogel. A aderência daPseudomonas alcaligenes nas lentes de hidrogel foi menor se comparada com as de silicone, PMMA e acrílico. CONCLUSÃO: Os resultados sugerem que a aderência do Staphylococcus epidermidis e da Pseudomonas alcaligenes nas lentes intra-oculares é influenciada pelo tipo de material da lente e pela espécie do microorganismo.

    Urinary incontinence (UI) is common and the relationship among its subtypes complex. Our objective was to describe the natural history and predictors of the incontinence subtypes stress, urgency, and mixed, in middle-aged and older US women. We tested our hypothesis that UI subtype history predicted future occurrence, evaluating subtype incidence/remission over multiple time points in a stable cohort of women. We analyzed longitudinal urinary incontinence data in 10,572 community-dwelling women aged ≥50 in the 2004-2010 Health and Retirement Study. Mixed, stress, and urgency incontinence prevalence (2004, 2006, 2008, 2010) and 2-year cumulative incidence and remissions (2004-2006, 2006-2008, 2008-2010) were estimated. Patient characteristics and incontinence subtype status 2004-2008 were entered into a multivariable, transition model to determine predictors for incontinence subtype occurrence in 2010. The prevalence of each subtype in this population (median age 63-66) was 2.6-8.9 %. Subtype incidence equaled 2.1-3.5 % and remissions for each varied between 22.3 and 48.7 %. Incontinence subtype incidence predictors included ethnicity/race, age, body mass index, and functional limitations. Compared with white women, black women had decreased odds of incident stress incontinence and Hispanic women had increased odds of stress incontinence remission. The age range 80-90 and severe obesity predicted incident mixed incontinence. Functional limitations predicted mixed and urgency incontinence. The strongest predictor of incontinence subtype was subtype history. The presence of the respective incontinence subtypes in 2004 and 2006 strongly predicted 2010 recurrence (odds ratio [OR] stress incontinence = 30.7, urgency OR = 47.4, mixed OR = 42.1). Although the number of remissions was high, a previous history of incontinence subtypes predicted recurrence. Incontinence status is dynamic, but tends to recur over the longer term.

    Numerical typing is an important perceptual-motor task whose performance may vary with different pacing, finger strategies and urgency of situations. Queuing network-model human processor (QN-MHP), a computational architecture, allows performance of perceptual-motor tasks to be modelled mathematically. The current study enhanced QN-MHP with a top-down control mechanism, a close-loop movement control and a finger-related motor control mechanism to account for task interference, endpoint reduction, and force deficit, respectively. The model also incorporated neuromotor noise theory to quantify endpoint variability in typing. The model predictions of typing speed and accuracy were validated with Lin and Wu's (2011) experimental results. The resultant root-mean-squared errors were 3.68% with a correlation of 95.55% for response time, and 35.10% with a correlation of 96.52% for typing accuracy. The model can be applied to provide optimal speech rates for voice synthesis and keyboard designs in different numerical typing situations. An enhanced QN-MHP model was proposed in the study to mathematically account for the effects of pacing, finger strategies and internalised urgency on numerical typing performance. The model can be used to provide optimal pacing for voice synthesise systems and suggested optimal numerical keyboard designs under urgency.

    The International Continence Society (ICS) identifies several urinary incontinence (UI) subtypes: urgency urinary incontinence (UUI), stress UI (SUI), and mixed UI (MUI). UUI is a common symptom of overactive bladder (OAB) syndrome. Based on the current ICS definition of OAB, all patients with UUI have OAB, whereas not all patients with OAB have UUI. Because UUI is a chronic condition that is expected to increase in prevalence as the population of elderly individuals grows, it is important to understand its economic burden on society and patients and its cost components.  To summarize the published English language medical literature on estimates of the economic burden of UUI in the United States from a societal and patient perspective, including direct costs (diagnosis, treatment, routine care [including incontinence pads], and UUI-associated comorbidities/complications); indirect costs (lost wages by patients and caregivers and lost work productivity due to absenteeism and presenteeism); and intangible costs (pain, suffering, and decreased health-related quality of life).  A PubMed search of the literature for articles on the economic burden of UUI in the United States was conducted using the search terms (urgency urinary incontinence OR urge incontinence OR mixed incontinence OR overactive bladder) AND (burden OR cost OR economic) AND (United States), with limits for English language, publication from 1991 to 2011, humans, and adults (19+ years). Only primary articles of non-neurogenic UUI in the United States were retained.  Seven studies were identified that included data on the economic burden of UUI in the United States from a societal and patient perspective. Although estimates of the total economic burden of UUI include direct, indirect, and intangible costs, none of the 7 U.S. studies included all of these cost components. Furthermore, the costs of UUI often could not be fully extracted from the costs of OAB, which include patients with and without UUI

    Epidemiologic aspects of traumatic dental injuries (TDI) were evaluated in the permanent dentition in a sample of 847 patients treated at the Dental Urgency Service of the Dental School of the Federal University of Goiás, Brazil, between May 2000 and May 2008. The statistical treatment analyzed data from frequency distribution and chi-square test. The level of significance was set at 5% for all analyses. The results showed a higher incident among males (610; 72.01%) with mean age of 6-10 year-old. Uncomplicated crown fracture (without pulp exposure) (502; 26.95%), avulsion (341; 18.30%) and complicated crown fracture (with pulp exposure) (330; 17.71%) were the most prevalent TDI. The prevalence of trauma throughout the years showed proportionality, being observed a larger number of cases between July and September (249; 29.39%). The most affected teeth were the maxillary central incisors (65.65%), followed by the maxillary left lateral incisors (19.67%). In 311 participants (18.25%), only one tooth was involved, while in most patients (536; 81.75%), TDI occurred in more than one tooth. Significant proportion (82.27%) of traumatized teeth presented completely formed root apex. The main etiologic factors involved in TDI were falls (51.71%), traffic accidents (22.90%) and violence (5.67%). Based on the obtained data, it may be concluded that accurate policies of TDI prevention must be established, capable of stimulating the exposure of appropriate protocols for management of these lesions. The prevalence of TDI in Goiânia subpopulation is compared to the prevalence reported in epidemiological studies in others populations.

    Treatments targeting vanilloid receptor TRPV1 are effective in some bladder disorders. Our aim was to determine the expression profiles of TRPV1 in regions of human bladder and test the hypothesis that there would be an upregulation of TRPV1 in mucosa of patients with bladder hypersensitivity but not idiopathic detrusor overactivity (IDO). Women with sensory urgency (SU), interstitial cystitis (IC), and IDO were investigated by videourodynamics and cystoscopy. Control biopsies were used for comparison. Biopsies were dissected into mucosa and muscle, and evaluated for TRPV1 mRNA expression using quantitative competitive RT-PCR (QC-RT-PCR). TRPV1 mRNA from SU trigonal mucosa was significantly higher than control trigonal mucosa or SU bladder body mucosa. In contrast, in IDO patients, there was no difference between trigonal mucosa and body mucosa. In IC biopsies, RNA quality was substandard and unable to be used for analysis. The most striking finding was that TRPV1 mRNA expressed in SU trigonal mucosa was significantly inversely correlated with the bladder volume at first sensation of filling during cystometry. No such relationship was seen for IDO trigonal mucosa. No difference was seen in bladder body mucosa from any disease groups compared with age-matched control. The symptoms of SU were associated with the increased expression of TRPV1 mRNA in the trigonal mucosa. No upregulation or regional differences of TRPV1 mRNA were seen in IDO patients. TRPV1 may play a role in SU and premature first bladder sensation on filling.

    To explore the impact of urgency urinary incontinence (UUI) on well-being in non-institutionalized patients with overactive bladder (OAB) in a community sample. A cross-sectional web-based study was conducted in the general population, including males and females, >18 years of age. Patients with probable OAB were identified using a validated algorithm together with a score ≥8 on the OAB-V8 scale. Presence of coping behavior was considered determinant for the clinical diagnosis of OAB. Individual well-being was determined through a battery of patient-reported outcomes (PRO) measurements including assessment of health-related quality of life (EQ-5D), sleep disturbances (MOS Sleep), and life satisfaction (LISAT-8). Patients were grouped according to the number of daily UUI episodes (UUI severity): 0 (dry OAB),1, 2-3, or ≥4. Multivariate analysis to evaluate factors independently affecting quality of life was undertaken. A total of 396 patients (52.5% women, mean age: 55.3 [11.1] years, OAB-V8 mean score: 14.5 [7.9]) out of 2035 subjects participating from the general population met the criteria for OAB: 203 (51.3%) with 0episodes, 119 (30.1%) with 1, 52 (13.1%) with 2 or 3, and 22 (5.6%) with ≥4 episodes. A statistically significant linear adjusted association was found between number of UUI episodes and PRO scores. Participants with more episodes had poorer health profiles and self-evaluated quality of life, worse life satisfaction, and more sleep disturbances and fewer hours of sleep per night. Number of incontinence episodes was independent factor to affect quality of life using both LISAT-8 and MOS questionnaires. Severity of UUI was significantly associated with poorer individual well-being in subjects with OAB in a community sample in Spain. Copyright © 2015 AEU. Publicado por Elsevier España, S.L.U.

    The Eurotransplant High-Urgency (HU) Heart Transplantation Program allows urgent heart transplants to be carried out in rapidly deteriorating patients with acute-to-chronic heart failure on the elective waiting list. But do the results of HU heart transplantation justify performing primary heart transplantation in these critically ill patients and offer an acceptable outcome? Between 2000 and 2004, 64 heart transplantations (HTx) (32 elective and 32 HU-HTx) were performed in our department. After having been accepted in an auditing process based on HU criteria, intensive care patients in NYHA functional class IV (cardiac index 1.7 l/min/qm BS), in end-organ failure (creatinine 1.5 mg/dl), and with catecholamine dependence (dobutamine 8 microg/kg/min), are given priority with respect to organ allocation, and their data were compared to data from elective patients from the same period. HU requests were accepted in 97 % of cases. Two requests were not accepted, and both patients with contraindications for assist device implantation died within one week. The HU patients were 100 % in NYHA class IV, 93 % of the elective patients were in NYHA class III. Waiting time on the HU list was 13 days, and 7 of these patients died before HTx. Following heart transplantation, survival rates at 30 days and at one year of the HU group were 88 % and 85 % versus 94 % and 93 % in the elective group. This study shows that end-stage heart failure patients in the HU program can be transplanted primarily with good results if an organ is available in time. We are still in the position where the HU program only manages the organ shortage; there are still too many patients on the waiting list who die before receiving a donor organ.

    Full Text Available This study examined whether urgency, a disposition to rash action under conditions of strong emotion, moderates associations between internalizing symptoms and alcohol use and related expectancies. Data from the Camden Youth Development Study, a longitudinal, community-based study of early adolescents ( N = 144, mean age at intake = 11.9 years; 65% Hispanic, 30% African-American; 50% male, were used. Self-report questionnaire measures of depressive symptoms, social and generalized anxiety symptoms, urgency, alcohol use, and alcohol expectancies were used. Mixed models were used to examine the effects of internalizing symptoms, urgency, and their interaction on alcohol use and expectancy trajectories over time. Depressive symptoms interacted with urgency such that youth with high levels of both tended to have elevated levels of global positive alcohol expectancies. Social anxiety symptoms interacted with urgency to be associated with increasing levels of social behavior alcohol expectancies such that youth with high levels of both tended to experience particular increases in these expectancies over time. Generalized anxiety was not found to be associated with alcohol-related constructs. Therefore, high levels of urgency combine with depressive and social anxiety symptoms to be associated with particularly increased risk for alcohol expectancies that are associated with later alcohol use and problems, indicating particular risk for youth with these combinations of personality traits and psychopathology symptoms.

    Traditionally, the urinary tract has been thought to be sterile in the absence of a clinically identifiable infection. However, recent evidence suggests that the urinary tract harbors a variety of bacterial species, known collectively as the urinary microbiome, even when clinical cultures are negative. Whether these bacteria promote urinary health or contribute to urinary tract disease remains unknown. Emerging evidence indicates that a shift in the urinary microbiome may play an important role in urgency urinary incontinence (UUI). The goal of this prospective pilot study was to determine how the urinary microbiome is different between women with and without UUI. We also sought to identify if characteristics of the urinary microbiome are associated with UUI severity. We collected urine from clinically well-characterized women with UUI (n = 10) and normal bladder function (n = 10) using a transurethral catheter to avoid bacterial contamination from external tissue. To characterize the resident microbial community, we amplified the bacterial 16S rRNA gene by PCR and performed sequencing using Illumina MiSeq. Sequences were processed using the workflow package QIIME. We identified bacteria that had differential relative abundance between UUI and controls using DESeq2 to fit generalized linear models based on the negative binomial distribution. We also identified relationships between the diversity of the urinary microbiome and severity of UUI symptoms with Pearson's correlation coefficient. We successfully extracted and sequenced bacterial DNA from 95% of the urine samples and identified that there is a polymicrobial community in the female bladder in both healthy controls and women with UUI. We found the relative abundance of 14 bacteria significantly differed between control and UUI samples. Furthermore, we established that an increase in UUI symptom severity is associated with a decrease in microbial diversity in women with UUI. Our study provides further

    To determine the bowel symptoms associated with diabetes and diabetes-related factors after excluding gastrointestinal (GI) organic diseases. Participants were 4738 (603 diabetic and 4135 non-diabetic) patients who underwent colonoscopy and completed a questionnaire. On the day of pre-colonoscopy, 9 symptoms (borborygmus, abdominal distension, increased flatus, constipation, diarrhea, loose stools, hard stools, fecal urgency, and incomplete evacuation) were prospectively evaluated on a 7-point Likert scale. The test-retest reliability of the bowel symptom scores from the baseline and second questionnaires was analyzed using kappa statistics. Associations between bowel symptom scores and diabetes or diabetes-related factors were analyzed by a rank-ordered logistic model adjusted for related confounders, and odds ratios (ORs) were estimated. In multivariate analysis, constipation [adjusted odds ratio (AOR) = 1.57, CI: 1.33-1.85, P associated with diabetes, and fecal urgency (AOR = 1.16, CI: 0.99-1.37, P = 0.07) and incomplete evacuation (AOR = 1.16, CI: 1.00-1.36, P = 0.06) were marginally associated with diabetes. These symptoms remained associated even after excluding organic GI diseases on colonoscopy. Test-retest reliability of symptom score with a mean duration of 3.2 mo was good (mean kappa, 0.69). Associations of symptoms with diabetes-related factors were found; constipation with HbA1c ≥ 8.0% (AOR = 2.11, CI: 1.19-3.73), body mass index (BMI) associated with constipation, hard stools, fecal urgency, and incomplete evacuation, and poor glycemic control, duration, leanness, and nephropathy affect the risk of these symptoms.

    To assess the efficacy of pelvic floor physical therapy (PFPT) as primary treatment of urinary urgency and frequency symptoms We conducted a prospective cohort study of women with urinary urgency and frequency symptoms. Participants underwent PFPT once or twice per week for 10 weeks. Symptom improvement was assessed by validated questionnaires (Pelvic Floor Distress Inventory-Short Form 20 and Patient Global Impression of Improvement), voiding diaries, and subjective measures. Fifty-seven participants enrolled; 21 (36.8%) withdrew or completed less than 5 weeks of PFPT. Thirty-one (54.4%) of the remaining 36 participants completed 10 weeks of PFPT. The mean age of the study group (n = 36) was 48.9 ± 15.0 years. The primary diagnoses were overactive bladder syndrome (n = 24, 66.7%) and painful bladder syndrome (n = 12, 33.3%). Women attended a median of 14.0 (interquartile range [IQR], 8.0-16.0) PFPT visits over a median of 11.9 weeks (IQR, 10.0-18.1). At baseline, the median Pelvic Floor Distress Inventory-Short Form 20 score was 79.2 (IQR, 53.1-122.9), and decreased to 50.0 (IQR, 25.0-88.5; P therapies. The high dropout rates suggest that motivation or logistic factors may play a significant role in the utilization and success of this treatment option.

    The personality trait of impulsivity is predictive of heavy drinking and consequences among college students. The current study examined how impulsivity-measured via positive urgency, negative urgency, and sensation seeking-and a person's beliefs about the role alcohol plays in the college experience relate to drinking and consequences in a sample of 470 college students (mean age=19 years, 61.3% female, 59.8% White). In support of the hypotheses, sensation seeking independently predicted greater drinking, and both positive urgency and negative urgency predicted greater experience of alcohol-related negative consequences after controlling for consumption level. Moreover, alcohol beliefs moderated the relationship between impulsivity types and alcohol outcomes. Among students high (versus low) in sensation seeking, strong beliefs about alcohol's role in college life were related to significantly greater drinking, and among students high (versus low) in negative urgency, endorsing strong beliefs about alcohol's role in college life were related to greater levels of alcohol-related negative consequences. Overall, findings inform college prevention efforts by highlighting the need to distinguish unique facets of impulsivity and examine how they intersect with students' beliefs about alcohol in college. © 2013.

    Acute exposure of part of the skin to cold stimuli can evoke urinary urgency, a phenomenon termed acute cold-induced urgency (ACIU). Despite its high prevalence, particularly in patients with overactive bladder, little is known about the mechanisms that induce ACIU. To develop an animal model of ACIU and test the involvement of cold-activated ion channels transient receptor potential (TRP) M8 and TRPA1. Intravesical pressure and micturition were monitored in female mice (wild-type C57BL/6J, Trpa1(-/-), Trpm8(+/+), and Trpm8(-/-)) and Sprague Dawley rats. An intravesical catheter was implanted. Localized cooling of the skin was achieved using a stream of air or topical acetone. The TRPM8 antagonist (N-(3-aminopropyl)-2-{[(3-methylphenyl) methyl]oxy}-N-(2-thienylmethyl)benzamide (AMTB) or vehicle was injected intraperitoneally. Frequencies of bladder contractions and voids in response to sensory stimuli were compared using the Mann-Whitney or Kruskal-Wallis test. Brief, innocuously cold stimuli applied to different parts of the skin evoked rapid bladder contractions and voids in anesthetized mice and rats. These responses were strongly attenuated in Trpm8(-/-) mice and in rats treated with AMTB. As rodent bladder physiology differs from that of humans, it is difficult to directly extrapolate our findings to human patients. Our findings indicate that ACIU is an evolutionarily conserved reflex rather than subconscious conditioning, and provide a useful in vivo model for further investigation of the underlying mechanisms. Pharmacological inhibition of TRPM8 may be useful for treating ACIU symptoms in patients. Brief cold stimuli applied to the skin can evoke a sudden desire to urinate, which can be highly bothersome in patients with overactive bladder. We developed an animal model to study this phenomenon, and found that it depends on a specific molecular cold sensor, transient receptor potential M8 (TRPM8). Pharmacological inhibition of TRPM8 may alleviate acute cold

    Full Text Available A exposição à radiação ultravioleta está relacionada ao aparecimento de patologias oculares como ceratites, cataratas, degenerações maculares ou pterígio. Esta radiação está dividida em 3 tipos de acordo com o seu comprimento de onda: Uv-A (320-400nm, Uv-B (290-320nm e Uv-C (100-290nm. A indústria óptica desenvolveu filtros de ultravioleta para lentes intra-oculares, lentes de contato e lentes de óculos. OBJETIVO: Avaliar a eficácia do filtro de ultravioleta em lentes de contato de alta hidratação. MÉTODOS: Seis grupos de lentes de contato de alta hidratação e de marcas diferentes, contendo 3 unidades novas e iguais foram estudadas, observando-se o percentual de transmissão da energia luminosa de 200 a 400 nm através de um espectofotômetro. RESULTADOS: Os 3 grupos que apresentavam filtro de ultravioleta causaram uma queda abrupta na transmissão da radiação ultravioleta de 400 nm até 340 nm, ocorrendo um aumento na transmissão entre 240 a 300 nm até um nível máximo de 45%. Abaixo de 240 nm e entre 300 e 340 nm, houve um completo bloqueio da transmissão da radiação ultravioleta. Os 3 grupos que não apresentavam filtros de ultravioleta causaram uma queda abrupta na transmissão da radiação ultravioleta abaixo de 240 nm, ocorrendo um bloqueio completo de transmissão abaixo de 220 nm. CONCLUSÃO: As lentes de contato sem filtro Uv testadas não bloquearam com eficácia a radiação Uv-A, B ou C, e as com filtro bloquearam quase totalmente a radiação Uv-B e parcialmente a radiação Uv-A e Uv-C.The exposure to ultraviolet radiation is associated with the beginning of ocular pathologies like keratites, cataract, age-related macular degeneration and pterygium.

    The mechanism of sacral neuromodulation is poorly understood. We compared brain activity during urgency before and after sacral neuromodulation in women with overactive bladder and according to response to treatment. Women with refractory overactive bladder who elected for sacral neuromodulation were invited to undergo a functional magnetic resonance imaging exam before and after treatment. During the imaging exams, the bladder was filled until urgency was experienced. Regions of interest were identified a priori, and brain activity in these regions of interest was compared before and after treatment as well as according to treatment response. A whole brain exploratory analysis with an uncorrected voxel level threshold of pbrain regions that changed after sacral neuromodulation. Among 12 women who underwent a pretreatment functional magnetic resonance imaging exam, seven were successfully treated with sacral neuromodulation and underwent a posttreatment exam. After sacral neuromodulation, brain activity decreased in the left anterior cingulate cortex, bilateral insula, left dorsolateral prefrontal cortex and bilateral orbitofrontal cortex (all pbrain regions with increased activity after sacral neuromodulation.

    Research suggests that negative affect, negative urgency, and thought suppression are related to bulimic symptoms, either directly or indirectly. This study examined associations between these constructs in a sample at-risk for bulimic symptoms. Participants (N = 80) recruited from a residential substance abuse treatment facility completed self-report questionnaires. A regression-based bootstrapping approach was used to examine the indirect effect of negative affect on bulimic symptoms through negative urgency and the moderating role of thought suppression in the association between negative affect and negative urgency. Results revealed a significant indirect effect, significant moderation, and a significant moderated mediation effect, with an indirect effect of negative affect on bulimic symptoms through negative urgency, conditional upon low to moderate (but not high) levels of thought suppression. These findings suggest that negative affect may promote rash actions, particularly in the context of low to moderate thought suppression, leading to increased risk of bulimic symptoms.

O objetivo desta pesquisa consiste na realização de uma busca e análise sistemática da literatura que aborda as capacidades das organizações sob a lente da ambidestria e orientação estratégica em ambientes de elevada turbulência. A sessão de resultados apresenta as principais abordagens referentes às capacidades de exploração e explotação dos recursos e orientação estratégica. Apresenta-se também uma análise a respeito de como o ambiente modera e influencia a utilização desses recursos em contextos de rápida mudança e elevada instabilidade. Identificou-se que parte das pesquisas não expõe de forma clara a relação entre a ambidestria e outros constructos. Quando associados aos termos relacionados a ambientes turbulentos, muitas vezes são utilizados apenas de forma superficial, servindo somente de contexto para o estudo; em outras vezes, é abordado de forma mais ativa, sendo apresentado como moderador direto sobre as variáveis analisadas. Novos trabalhos devem considerar a ambidestria organizacional no curto prazo e suas respectivas implicações de desempenho no longo prazo. Existe ainda a necessidade de criar uma visão mais dinâmica de como organizações ambidestras adaptam-se às mudanças, considerando o impacto sobre a orientação estratégica em diferentes contextos.

    Full Text Available Resumo: Atualmente, a cápsula anterior e o epitélio da lente tem sido cada vez mais estudados, com o intuito de reduzir as possíveis complicações do pós-operatório da remoção da catarata, tal como a opacidade da cápsula posterior, alteração ocasionada principalmente pela diferenciação e migração das células do epitélio lenticular para a cápsula posterior da lente. O objetivo deste estudo foi analisar a composição molecular da cápsula anterior da lente pela técnica histoquímica de PAS (avaliação de proteoglicanos e picrosirius red (avaliação de colágeno IV, em cães idosos com catarata diabética e não diabética do tipo hipermadura, submetidos ao uso ou não de azul de tripano a 0,1 % durante a facoemulsificação. Vinte e sete cães foram estudados, incluindo 21 fêmeas e 6 machos, de 8 a 12 anos de idade (média = 9,6 anos, de diversas raças e divididos em 2 grupos: GC (catarata hipermadura e GCD (catarata diabética. Os resultados das análises realizadas mostraram que ambas as amostras, tanto as provenientes das cataratas hipermaduras, quanto das diabéticas, apresentam semelhante composição molecular de proteoglicanos e colágeno IV e isto independente da utilização de azul de tripano a 0,1 %. Conclui-se, portanto, que se os resultados obtidos forem decorrentes de alterações provocadas pelo rápido metabolismo da catarata diabética e pela cronicidade da catarata hipermadura sugere-se que o comprometimento da estrutura capsular seja de intensidade equivalente e, por consequência, que isto também possa prejudicar o metabolismo das células do epitélio anterior da lente, diminuindo assim a incidência da opacidade da cápsula posterior de cães com catarata diabética e hipermadura submetidos à facoemulsificação.

    The study sought to determine the symptomatic profile of men with lower urinary tract symptoms (LUTS) who visited a urology clinic in Spain and its impact on their health-related quality of life (HRQL). A national, epidemiological cross-sectional study was conducted and included 291 urology clinics. The prevalence of storage LUTS was investigated in 25,482 men. The study collected sociodemographic and clinical data from a subgroup of 1015 patients with storage LUTS who filled out the International Prostate Symptom Score (IPSS), Overactive Bladder Questionnaire Short Form (OABq-SF) and Patient Perception of Bladder Condition (PPBC) questionnaires. The impact of urinary urgency on HRQL was analysed. The prevalence of storage LUTS was 41%, increasing with age: 14.1%, 41.5% and 60.8% for patients aged 18-49, 50-64 and ≥65 years, respectively. Of the 1015 selected patients, only 2.6% had storage symptoms exclusively. Symptom severity (IPSS) increased with age. Nocturia, frequency and urgency were the most common symptoms and had the most impact on HRQL (IPSS and OABq-SF). The number of urgency episodes was inversely correlated with the HRQL (r=-.773; P<.0001). In the multivariate analysis, only the IPSS and OABq-SF bother scores were significant predictors of HRQL (P<.001). Storage LUTS are highly prevalent among patients attending urology clinics in Spain. The severity of the urgency (number of urgency episodes) predicted a poorer quality of life for the patient.

    Blood transfusions are contributing to a higher rate of hepatitis C virus (HCV) in Pakistan. Half of all blood transfusions in Pakistan are not screened for hepatitis C, hepatitis B or HIV. Family members donate blood that is likely not tested due to social stigma attached to HCV. Paid donations are also quite common in the country, especially by people who inject drugs (PWID), which increases the population’s exposure to HCV. Most of the population utilizes the private sector for their health needs; this sector has lax regulation due to the lack of oversight by the government or any other regulatory body. In addition, groups who are at most need for blood transfusions, such as hemophiliacs and those with thalassemia, have a higher rate of hepatitis C. This fact reinforces the need for blood transfusion reform in Pakistan, which includes improving oversight, upgrading infrastructure and promoting health literacy through cultural norms, according to the World Health Organization (WHO) recommendations. The lessons learned in Pakistan can be adapted to countries facing similar issues. PMID:29524949

    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

    Allosensitized children who require a negative prospective crossmatch have a high risk of death awaiting heart transplantation. Accepting the first suitable organ offer, regardless of the possibility of a positive crossmatch, would improve waitlist outcomes but it is unclear whether it would result in improved survival at all times after listing, including posttransplant. We created a Markov decision model to compare survival after listing with a requirement for a negative prospective donor cell crossmatch (WAIT) versus acceptance of the first suitable offer (TAKE). Model parameters were derived from registry data on status 1A (highest urgency) pediatric heart transplant listings. We assumed no possibility of a positive crossmatch in the WAIT strategy and a base-case probability of a positive crossmatch in the TAKE strategy of 47%, as estimated from cohort data. Under base-case assumptions, TAKE showed an incremental survival benefit of 1.4 years over WAIT. In multiple sensitivity analyses, including variation of the probability of a positive crossmatch from 10% to 100%, TAKE was consistently favored. While model input data were less well suited to comparing survival when awaiting transplantation across a negative virtual crossmatch, our analysis suggests that taking the first suitable organ offer under these circumstances is also favored. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Full Text Available The object of the paper is to analyze the spatial structure of land and identification of the needs of consolidation works and exchange of land in the villages of the Sławno municipality, lying in the district of Opoczno, in the Łódzkie Voivodship. The authors use the method of zero unitarisation for the purposes of determining the order of undertaking consolidation works and exchange of land in the area of research. The basis for calculation is the database of 19 factors (x1–x19 characteristic for the listed five groups of issues, describing each of the following villages. The obtained results, in a form of synthetic meter for each village, allowed creating the hierarchy of the urgency of carrying out consolidation works. The problem of excessive fragmentation of farms, constituting the collections of a certain number of parcels, in a broader sense, is one of the elements that prevent the acceleration of reforms by conversion of the Land and Buildings Register (EGiB in a full valuable real estate cadastre in Poland. The importance of the problem is highlighted by the fact that there are ecological grounds in the study area, significant from the point of view of environmental protection.

    Full Text Available This article has as object of study the stabilization of the summary judgment of urgency Institute, and as an analytical perspective the theory of fundamental rights. We intend to investigate the material fundamentality of this Institute having as theoretical premise the dual nature of the principle of justice access as a right and a fundamental guarantee. In this research line, we understand the summary judgment of urgency Institute and its stabilization as a tool of the fundamental right of access to justice and as a content derived from the fundamental guarantee of access to justice that assures it. The material fundamentality of the Institute, however, can only be sustained if the stability of a protection given under the summary cognition, doesn’t offend, in its genesis, the audi alteram partem principle.

    Careful planning is essential to ensure blood availability during shortages. Triaging supply is one proposed strategy; however, few data concerning the urgency of transfusion are available to inform planning. This study sought to determine the proportion of red blood cells (RBCs) used for clinically urgent indications. A total of 5132 RBC units were randomly selected at point of production and distributed into general statewide inventory over a 9-month period. These selected units carried case report forms, for completion at the point of hospital issue for transfusion. Completed forms were returned to the blood service for collation and analysis, capturing information on indication and clinical urgency of supply, including use for potentially deferrable elective surgery. Data from 5052 RBC units indicated that 95.6% were transfused. Approximately one-third of transfused units were used to support surgery, one-third for hematology/oncology, and one-third for other medical and miscellaneous indications. Where used for surgery, 25.7% (95% confidence interval [CI], 23.4%-28.0%) were for elective procedures, although urgency of surgery was unknown in 17.1% (95% CI, 15.2%-19.2%) of cases. Supply for nonurgent medical indications and elective surgery only accounted for 9.8% (95% CI, 9.0%-10.6%) of use, with 53.4% (95% CI, 52.0%-54.8%) of RBCs required within 24 hours. The majority of RBCs are transfused with a high degree of clinical urgency, with only a minor proportion required to support elective surgery.

    The aim of the study was to identify the characteristics of self-referrals for non-urgent conditions to the ER, and compare urgency evaluation between patients and nurses. The participants were 73 Israeli clients who arrived at ER without referral from a physician, during the morning shift, and were discharged home after treatment. Their average age was 39.4 years. Most of the visits resulted from orthopedic problems. Over 60% indicated that they had chosen the ER because the treatment there was better, and a third reported that they usually turn to ER when they feel sick. In most cases, the visits were within 3 h of the symptoms emerging, and about a third of the participants indicated that lately they had been under situations of stress and anxiety. Significant differences (p=0.000) were found between nurses and patients, in the urgency evaluation of the visit. While most of the clients (77%), evaluated their condition as urgent to most urgent, most of the nurses (78%) evaluated it as non-urgent. Identifying the characteristics of the non-urgent use of the ER and the differences between caregivers and patients regarding the urgency evaluation of the visit, will provide insights into the population perceived as a burden on the work of the ER as well as benefiting and improving services.

    Medication adherence with urgency urinary incontinence (UUI) treatment is challenging and the best assessment methodology is uncertain. We sought to describe adherence with anticholinergic (AC) versus placebo (P) by comparing pill counts and MEMSCAP event data and to identify factors associated with adherence. The randomized controlled AC versus Botox Comparison trial of women with moderate to severe idiopathic UUI included 126 participants initiating AC plus P bladder injection and 121 receiving P pills plus Botox injection. Adherence data on 243 participants (124 AC and 119 P) were calculated by pill count and MEMSCAP data for each 2-month interval during the 6-month study that allowed for dose escalation/drug change. Overall composite adherence estimates were calculated using the average of both methods and weighted by the duration of each 2-month interval. Treatment groups had no significant differences in dosing duration (P = 0.76) or mean adherence (AC, 83.3% [16.8] vs. P, 84.8% [13.8]). Only 53% of women met the dichotomous outcome of more than 80% adherence during all intervals. Correlation between adherence by pill counts versus MEMSCAP decreased over time with pill counts demonstrating higher adherence than MEMSCAP (r = 0.53, 0.50, and 0.36 for each 2-month interval). Lower adherence was associated with higher baseline incontinence severity and better UUI quality of life for the AC group and with current smoking status in both groups. Adherence using pill counts and MEMSCAP was reasonably correlated and similar in both the AC and P groups. In the AC group, higher baseline incontinence severity and better UUI Quality of Life were associated with decreased adherence. Smokers were less adherent.

    Although waste from coffee processing is a valuable resource to make biogas, compost, and nutrient-rich animal food, it is usually dumped into nearby water courses. We carried out water quality assessment at 44 sampling sites along 18 rivers that receive untreated waste from 23 coffee pulping and processing plants in Jimma Zone, Ethiopia. Twenty upstream sampling sites free from coffee waste impact served as control, and 24 downstream sampling sites affected by coffee waste were selected for comparison. Physicochemical and biological results revealed a significant river water quality deterioration as a result of disposing untreated coffee waste into running water courses. During coffee-processing (wet) season, the highest organic load (1,900 mg/l), measured as biochemical oxygen demand, depleted dissolved oxygen (DO) to a level less than 0.01 mg/l, and thus curtailed nitrification. During off season, oxygen started to recuperate and augmented nitrification. The shift from significantly elevated organic load and reduced DO in the wet season to increased nitrate in the off season was found to be the determining factor for the difference in macroinvertebrate community structure as verified by ordination analysis. Macroinvertebrate diversity was significantly reduced in impacted sites during the wet season contrary to the off season. However, there was a significant difference in the ratio of sensitive to pollution-tolerant taxa in the off season, which remained depreciated in the longer term. This study highlights the urgency of research exploring on the feasibility of adopting appropriate pollution abatement technologies to implement ecologically sound coffee-processing systems in coffee-growing regions of Ethiopia.

    We describe the rationale and methodology for a study comparing mind-body treatment and pharmacotherapy in women with urgency urinary incontinence (UUI). To explore brain associations in UUI, a subset of patients will also undergo functional magnetic resonance imaging (fMRI). We hypothesize that hypnotherapy, a mind-body intervention, will be at least as effective as pharmacotherapy in treating UUI. We also hypothesize that fMRI findings will change following treatment, with changes potentially differing between groups. We describe the development and design challenges of a study comparing the efficacy of hypnotherapy and conventional pharmacotherapy in the treatment of UUI. The study randomizes women to either of these treatments, and outcome measures include bladder diaries and validated questionnaires. Sample size estimates, based on a noninferiority test (alpha = 0.025, beta = 0.20), after considering dropout subjects and subjects lost to follow-up, indicated that approximately 150 woman would be required to test the hypothesis that hypnotherapy is not inferior to pharmacotherapy within a 5 % noninferiority margin. The study will also evaluate fMRI changes in a subset of participants before and after therapy. Challenges included designing a study with a mind-body therapy and a comparison treatment equally acceptable to participants, standardizing the interventions, and confronting the reality that trials are time-consuming for participants who have to make appropriate accommodations in their schedule. Study enrollment began in March 2013 and is ongoing. We describe the design of a randomized controlled trial comparing mind-body therapy and pharmacotherapy in the treatment of UUI and the challenges encountered in its implementation.

    2013-01-01

    Background Associations between type A behaviour pattern (TABP) and injuries are inconsistent. These inconsistencies may be due to different effects of various components of TABP, namely time urgency/impatience, hostility and competitive drive. It is important to examine the relationship between the global TABP, its two components, and unintentional injuries, among undergraduates in China. Methods On the basis of a previous cross-sectional study, we conducted a matched case–control study. 253 cases and an equal number of age-, gender-, and major-matched controls were included. The questionnaire solicited socio-demographic information, the experience of injuries, the scale of TABP, and other potential confounding factors. Besides the correlation between the global TABP and injuries, the influences of the two components of TABP on injuries were also evaluated. Conditional logistic regression was used to determine the crude odds ratios (ORs) and adjusted ORs of injury events. Results A dose–response relationship was apparent among students who rated themselves higher on the TABP scale (P-value for trend, 0.002), with a crude OR of 2.93 (95% CI: 0.93–9.19) for injuries comparing those with TABP to those with type B behaviour pattern (TBBP). After adjustment for potential confounding factors, TABP remained statistically significant, and the adjusted OR was 5.52 (95% CI: 1.43–21.27); from a comparison of students with TABP to those with TBBP. A dose–response relationship was also apparent between the hostility component and nonfatal injuries, both in crude analysis and after adjusting for other confounders. The relationship between time-hurry and injuries was not statistically significant, based on univariate and multivariate analyses. Conclusions Both the global TABP and the hostility component were associated with a dose response increase in the risk of non-fatal unintentional injuries among Chinese undergraduates. Further studies need to be conducted to

    To evaluate the effect of subject-controlled, on-demand, dorsal genital nerve (DGN) stimulation on non-neurogenic urgency urinary incontinence (UUI) in a domestic setting. Non-neurogenic patients >18 years with overactive bladder symptoms and UUI were included. Exclusion criteria were mainly stress urinary incontinence. Patients underwent 1 week of subject-controlled, on-demand, DGN stimulation, delivered by a percutaneously placed electrode near the DGN connected to an external stimulator (pulse-rate 20 Hz, pulse-width 300 μs). Patients activated the stimulator when feeling the urge to void and stimulated for 30 s. The amplitude was set at the highest tolerable level. A bladder diary including a severity score of the UUI episodes/void (scores: 0 = none, 1 = drops, 2 = dashes, 3 = soaks) and a padtest was kept 3 days prior to, during, and 3 days after the test period. The subjective improvement was also scored. Seven patients (4 males/3 females) were enrolled, the mean age was 55 years (range 23-73). Six completed the test week. In the remaining patient the electrode migrated and was removed. 5/6 finalized the complete bladder diary, 1/6 recorded only the heavy incontinence episodes (score = 3). 4/6 completed the padtest. In all patients who finalized the bladder diary the number of UUI episodes decreased, in 3/5 with ≥60%. The heavy incontinence episodes (score = 3) were resolved in 2/6 patients, and improved ≥80% in the other 4. The severity score of the UUI episodes/void was improved with ≥ 60% in 3/5 patients. The mean subjective improvement was 73%. This feasibility study indicates that subject-controlled, on-demand DGN stimulation using a percutaneously placed electrode is possible over a longer time period, in a home setting, with a positive effect on non-neurogenic overactive bladder symptoms with UUI. Although the placement is an easy procedure, it is difficult to fixate the electrode to keep it in the correct position. Improvements in hardware

    Full Text Available We report a case of a 58-year-old man presenting with a spontaneous and late in-the-bag intraocular lens dislocation to the vitreous. A previous uneventful extracapsular cataract extraction with can-opener style capsulotomy and implantation of a polymethylmethacrylate three-piece lens was performed and, two years after the surgery, the patient developed capsule contraction syndrome with a fibrotic ring formation and dislocation of the intraocular lens. Although uncommon and related mainly to continuous curvilinear capsulorhexis, capsule contraction syndrome occurs in patients undergoing extracapsular cataract surgery with can-opener style and polymethylmethacrylate lens implantation, and can be the causative factor of intraocular lens dislocation.Os autores relatam o caso de homem de 58 anos de idade que apresentou deslocamento espontâneo e tardio de lente intra-ocular dentro do saco capsular para o vítreo. O paciente havia sido submetido a facectomia extracapsular com capsulotomia do tipo abridor de latas e implante de lente de polimetilmetacrilato de três peças sem intercorrências e, dois anos após a cirurgia, desenvolveu síndrome de contração capsular com formação de um anel fibrótico na cápsula e subluxação da lente intra-ocular. Embora incomum e relacionada principalmente com capsulorexe curvilínea contínua, a síndrome de contração capsular pode ocorrer em pacientes submetidos a facectomia extracapsular com capsulotomia do tipo abridor de latas e implante de lente de polimetilmetacrilato e pode ser o fator causador do deslocamento da lente intra-ocular.

    Stress has been implicated as a risk factor for hoarding, although past research has relied on cross-sectional and self-report designs. Using experimental methods and objective hypothetical behavioral hoarding paradigms, we investigated the direct effect of stress on in-the-moment saving and acquiring behavioral tendencies. We also evaluated whether distress tolerance (DT) and negative urgency interacted with stress to predict saving and acquiring behavioral tendencies. A sample of young adults (N=80) completed questionnaires about DT and negative urgency. Participants were randomized to either a psychosocial stressor or nonstressful control task prior to completing two hypothetical behavioral hoarding paradigms. The discarding task asked participants to choose between saving and disposing of items. For the acquiring task, participants completed a computer-simulated shopping spree that measured items acquired. Unexpectedly, participants in the stress condition saved and acquired fewer items than those in the control condition. As hypothesized, stress interacted with DT to predict saving tendencies. The current study should be replicated in a clinical sample. Longitudinal studies are needed to further examine the long-term effect of stress on hoarding. This is the first examination of the direct effect of stress on saving and acquiring tendencies. Although some study hypotheses were not supported, several results are consistent with our predictions and suggest a complex relationship between stress and hoarding. If findings are replicated in a clinical sample, it may be that hoarding patients could benefit from treatments incorporating DT strategies. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available Objectives: The present study aimed to investigate if eating disorder patients differ in specific personality traits depending on a positive screening of food addiction and to find a model to predict food addiction in eating disorder patients using measures of personality and impulsivity. Methods: 278 patients having an eating disorder self-reported on food addiction, impulsivity, personality, eating and general psychopathology. Patients were then split into two groups, depending on a positive or negative result on the food addiction screening. Analysis of variance was used to compare means between the two groups. Stepwise binary logistic regression was used to obtain a predictive model for the presence of food addiction. Results: Patients with food addiction had lower self-directedness, and more negative urgency and lack of perseverance than patients not reporting addictive eating. The probability of food addiction can be predicted by high negative urgency, high reward dependence, and low lack of premeditation. Conclusions: Eating disorder patients who have more problems to pursue tasks to the end and to focus on long-term goals seem to be more likely to develop addictive eating patterns.

    Many researchers have identified impulsivity-related personality traits as correlates of and risk factors for nonsuicidal self-injury (NSSI). Using a longitudinal design, we tested the hypothesis that one such trait, negative urgency (the tendency to act rashly when distressed), predicts the onset of NSSI during the first year of college and a different trait, lack of perseverance (the disposition to fail to maintain focus on tasks that are difficult or boring), predicts the maintenance of NSSI during the first year of college. In a sample of n=1,158 college women (mean age=18.04, 95% of participants were 18 at Time 1), we found support for these hypotheses. Negative urgency, measured prior to college entry, predicted the onset of NSSI behavior across the first year of college (odds ratio=1.58). Lack of perseverance predicted the maintenance of NSSI status across the first year of college, controlling for prior NSSI behavior (odds ratio=1.73). These findings indicate that different impulsivity-related personality traits may play different roles in the risk process for NSSI. Copyright © 2015. Published by Elsevier Ltd.

    megacolon is a frequent disease in our emergencie hospital, and approached in the urgency by your complications as fecal impaction, volvulus and perforations. The ulcerations in the megacolons contribute as probable sites of perforations AIM: To compare the frequencies of stercoral ulceration in Chagas' megacolon operated at urgency, by volvulus or fecal impaction, and electively, aiming at a better surgical conduct in the urgency surgery METHODS: It was analyzed 356 anatomy-pathological exams from colon resection of operated patients due to Chagas' megacolon at urgency (102 cases; 29% and electively (254 cases; 71%, from 1980 to 2000. The surgical urgency indications were attributed to volvulus (71 cases; 69,6%, fecal impaction (25 cases; 24,5%, perforated acute abdomen after rectal catheter or sigmoidoscopy (6 cases; 5,9%. The ulceration frequency was compared in both groups of resections, using chi-square RESULTS: The pathological anatomy - of surgery resection obtained at urgency surgeries, showed 26 cases of ulceration (25,5% and in electively resections were verified 21 cases of ulceration (8,25%. The difference observed was statistically significant. The comparison among the groups of volvulus; fecal impaction and volvulus with fecal impaction, separately with electively surgery group evidenced significant differences in relation to volvulus and fecal impaction CONCLUSIONS: The higher frequency of ulcerations in the megacolon operated at urgency character emphasizes the needs of immediate resection of sigmoid colon, instead of conservative conduct of simple decompression colostomy, even in exploration laparotomy which the macroscopic examination of sigmoid does not show necrotic signs. This way, should prevent the occurrence of perforation in megacolon at mediate postoperative, with serious results.

    Abstract. Rhodnius stali Lent, Jurberg & Galvão is a Chagas Disease vector that colonize houses in the Alto Beni region, Bolivia and its biology is poorly known. Aiming to enhance the understanding about their biology, we observed a few parameters of its life cycle, at nymphal stages, comparing them with Rhodnius pictipes Stål a morphologically similar and phylogenetically close species. The following parameters were observed: time of hatching, development time from egg to adult (male and female separately, mortality rate, age at first blood meal and blood volume ingested by nymphs. In general, it was observed that the R. stali has longer cycle than R. pictipes, and in both species, the time between hatching the egg to adult in females is lower. Interestingly for R. stali, which is known to be capable of colonizing households, the mortality rate of nymphs was higher than observed in R. pictipes, something unexpected for species that colonize artificial structures and was observed in artificial environment. For R. stali, the first blood meal was, on average, four days later than for R. pictipes, species that ingested a greater total blood volume, possibly because of its bigger size. By knowing in depth the biological aspects of these species it will be possible to direct vector control more accurately, especially in regions where they colonize houses, as in the Alto Beni, Bolivia.

    To determine the effectiveness of 20 twice-weekly sessions of parasacral transcutaneous electrical neural stimulation (TENS) for treatment of urinary urgency and urge-incontinence in children and adolescents. A Phase II clinical trial was carried out with patients with urinary urgency or urge-incontinence aged between 5 and 14 years. Twenty TENS sessions were conducted, twice weekly, using a Quark® Dualpex 961 apparatus. The variables analyzed were daily micturition, dynamics ultrasonography of the lower urinary tract pre-and post-treatment and responses to a questionnaire on urinary leakage applied during each session. The mean age of the 25 children participating in the study was 7.80 ± 2.22 years, most were female (92%) and had urge-incontinence (92%). The difference in urinary leakage pre- and post-treatment was statistically significant ( p = 0.04); a decline in the symptom of urinary leakage was reported by all caregivers in children who completed the 20th session; the ultrasound parameters, although not statistically significant, showed a reduction in the percentage of children with detrusor contractions (from 62.5% to 43.5%); and a more adequate pre-micturition bladder volume of 4.2% post-treatment compared with 19.0% prior to treatment. The electro-stimulation carried out during the twice weekly sessions appeared to be effective and urinary incontinence declined in half of the patients from the 12th session onwards. However, there is a need for a study involving a larger number of patients to confirm the results obtained.

MÉTODOS: Se realizó un estudio descriptivo, prospectivo y transversal en el Instituto Cubano de Oftalmología «Ramón Pando Ferrer», durante el período de enero a junio del 2007. Se estudiaron variables como: edad, sexo, etiología de la catarata, técnica quirúrgica, localización del lente intraocular según biomicroscopia ultrasónica, así como complicaciones transoperatorias y posoperatorias. RESULTADOS: El 79 % de todos los pacientes operados tenían entre 60 y 79 años de edad y algo más de la mitad correspondió al sexo femenino con un 59 %. La catarata senil fue la etiología que predominó con un 74 % y en el 68 % de los casos el lente se localizó por biomicroscopia ultrasónica en el saco capsular. En los ojos donde el lente intraocular se localizó fuera del saco, la proporción de complicaciones transoperatorias y posoperatorias fueron significativamente mayoritarias, mientras que en los ojos donde el lente intraocular se encontraba en el saco, la mayoría no presentó complicaciones transoperatorias ni posoperatorias. CONCLUSIONES: Las diferencias entre las distintas localizaciones del lente intraocular se encontraron con significación estadística en el tipo de catarata, la presencia de complicaciones transoperatorias y posoperatorias, sin embargo, no se encontró relación estadística significativa entre la localización del lente intraocular con la técnica quirúrgica utilizada.OBJECTIVE: To determine the correlation between the location of the intraocular lens in the posterior chamber using ultrasonic biomicroscopy and the different surgical parameters in patients operated from cataract.

    Full Text Available A catarata, especialmente na espécie canina, é uma doença oftálmica importante. Seu tratamento é eminentemente cirúrgico, mas a perda do cristalino resulta em alta hipermetropia, e a visão fica comprometida. A correção pode ser feita com a utilização de lente intra-ocular (LIO. Este estudo teve por objetivo colher dados que pudessem fornecer subsídios métricos para a produção de LIOs a serem aplicadas em cães facectomizados, visando a restauração de visão adequada nos animais acometidos por catarata. Foram selecionados 120 cães de ambos os sexos, sadios ao exame clínico e sem evidência de doença ocular ao exame oftálmico de rotina. Foram realizados estudos ceratométrico e biométrico, pela ultra-sonografia modo-A. Uma fórmula específica foi utilizada para a determinação do poder dióptrico de uma LIO utilizada para substituir o cristalino extraído. O poder dióptrico da LIO foi correlacionado com o peso e o sexo dos animais, e entre os olhos direito e esquerdo. Baseado nestas correlações, concluiu-se que o poder dióptrico adequado para uma LIO a ser implantada em um cão facectomizado é influenciado principalmente pelo peso do animal, apesar de apresentar discretas diferenças quando comparado entre os olhos direito e esquerdo e entre machos e fêmeas.

  5. Duration and urgency of transfer in births planned at home and in freestanding midwifery units in England: secondary analysis of the Birthplace national prospective cohort study

    Science.gov (United States)

    2013-01-01

    Background In England, there is a policy of offering healthy women with straightforward pregnancies a choice of birth setting. Options may include home or a freestanding midwifery unit (FMU). Transfer rates from these settings are around 20%, and higher for nulliparous women. The duration of transfer is of interest because of the potential for delay in access to specialist care and is also of concern to women. We aimed to estimate the duration of transfer in births planned at home and in FMUs and explore the effects of distance and urgency on duration. Methods This was a secondary analysis of data collected in a national prospective cohort study including 27,842 ‘low risk’ women with singleton, term, ‘booked’ pregnancies, planning birth in FMUs or at home in England from April 2008 to April 2010. We described transfer duration using the median and interquartile range, for all transfers and those for reasons defined as potentially urgent or non-urgent, and used cumulative distribution curves to compare transfer duration by urgency. We explored the effect of distance for transfers from FMUs and described outcomes in women giving birth within 60 minutes of transfer. Results The median overall transfer time, from decision to transfer to first OU assessment, was shorter in transfers from home compared with transfers from FMUs (49 vs 60 minutes; p < 0.001). The median duration of transfers before birth for potentially urgent reasons (home 42 minutes, FMU 50 minutes) was 8–10 minutes shorter compared with transfers for non-urgent reasons. In transfers for potentially urgent reasons, the median overall transfer time from FMUs within 20 km of an OU was 47 minutes, increasing to 55 minutes from FMUs 20-40 km away and 61 minutes in more remote FMUs. In women who gave birth within 60 minutes after transfer, adverse neonatal outcomes occurred in 1-2% of transfers. Conclusions Transfers from home or FMU commonly take up to 60 minutes from decision to

    Additives are used for improving food structure or preventing its spoilage, for example. Many substances used as additives are also naturally present in food. The safety of additives is evaluated according to commonly agreed principles. If high concentrations of an additive cause adverse health effects for humans, a limit of acceptable daily intake (ADI) is set for it. An additive is a risk only when ADI is exceeded. The healthiness of food is measured on the basis of nutrient density and scientifically proven effects.

    Full Text Available In yoghurt production, mainly because of sensory characteristics, different types of additives are used. Each group, and also each substance from the same group has different characteristics and properties. For that reason, for improvement of yoghurt sensory characteristics apart from addition selection, the quantity of the additive is very important. The same substance added in optimal amount improves yoghurt sensory attributes, but too small or too big addition can reduce yoghurt sensory attributes. In this paper, characteristics and properties of mostly used additives in yoghurt production are described; skimmed milk powder, whey powder, concentrated whey powder, sugars and artificial sweeteners, fruits, stabilizers, casein powder, inulin and vitamins. Also the impact of each additive on sensory and physical properties of yoghurt, syneresis and viscosity, are described, depending on used amount added in yoghurt production.

    Additive and Polynomial Representations deals with major representation theorems in which the qualitative structure is reflected as some polynomial function of one or more numerical functions defined on the basic entities. Examples are additive expressions of a single measure (such as the probability of disjoint events being the sum of their probabilities), and additive expressions of two measures (such as the logarithm of momentum being the sum of log mass and log velocity terms). The book describes the three basic procedures of fundamental measurement as the mathematical pivot, as the utiliz

    To investigate whether people with intellectual disabilities (ID) in residential setting were more likely than people from the general population to request out-of-hours general practitioner (GP) care and whether these requests had a similar level of urgency. Cross-sectional routine data-based study. Two GP cooperatives providing out-of-hours primary care in an area in the Netherlands. 432 582 persons living in the out-of-hours service areas, of which 1448 could be identified as having an ID. GP cooperative records of all contacts in 2014 for people with and without ID were used to calculate the relative risk of requesting care and the associated level of urgency. Of the people with ID (448/1448), 30.9% requested out-of-hours GP care, whereas for the general population this was 18.4% (79 206/431 134), resulting in a relative risk of 1.7 (95% CI 1.6 to 1.8). We found a different distribution of urgency level for people with and without ID. Generally, requests for people with ID were rated as less urgent. People with ID in residential setting were more likely to request out-of-hours GP care than the general population. The distribution of the urgency level of requests differed between the two groups. The high percentage of demands relating to people with ID requesting counselling and advice suggests that some out-of-hours GP care may be avoidable. However, more insight is needed into the nature of out-of-hours primary care requests of people with ID to direct structural and reasonable adjustments towards the improvement of health information exchange in and around-the-clock access to primary care for people with ID. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To evaluate the prevalence of Overactive Bladder (OAB) and Urgency Urinary Incontinence (UUI) in males with Obstructive Sleep Apnea Syndrome (OSAS) using the OSAS grading system. A total of 194 patients who underwent Polysomnography (PSG) were included in our prospective cross sectional study. Patients were divided into four groups according to Apnea-Hypopnea Index (AHI). Group 1, 35 patients with normal AHI (Bladder (OAB-V8), ICIQ-SF, and IPSS questionnaires were filled out for all patients. Prevalence of OAB, UUI, nocturia, and scores of OAB-V8, ICIQ-SF, IPSS were compared between the study groups. The statistical analysis was adjusted by the demographics of age and BMI. The mean age was 44.6 ± 11.2 years, and the mean BMI was 29.9 ± 4.9 within the whole study group, and both were statistically different between the groups. The scores of OAB-V8 (P = 0.298), ICIQ-SF (P = 0.392), IPSS total, IPSS storage, and IPSS voiding (P = 0.268, P = 0.380, P = 0.167, respectively), the prevalence of OAB (P = 0.078), UUI (P = 0.423), and nocturia (P = 0.096) were not statistically different between the study groups. Our findings demonstrated that there is no increase in prevalence of OAB and UUI in relatively young adult male with OSAS. Furthermore, analysis revealed that the higher OSAS grade does not mean the higher prevalence of OAB. © 2017 Wiley Periodicals, Inc.

    We consider the problem of predicting an outcome variable using p covariates that are measured on n independent observations, in a setting in which additive, flexible, and interpretable fits are desired. We propose the fused lasso additive model (FLAM), in which each additive function is estimated to be piecewise constant with a small number of adaptively-chosen knots. FLAM is the solution to a convex optimization problem, for which a simple algorithm with guaranteed convergence to a global optimum is provided. FLAM is shown to be consistent in high dimensions, and an unbiased estimator of its degrees of freedom is proposed. We evaluate the performance of FLAM in a simulation study and on two data sets. Supplemental materials are available online, and the R package flam is available on CRAN.

    In this project a number of industrial and agricultural waste products have been characterised and evaluated in terms of alkali-getter performance. The intended use is for biomass-fired power stations aiming at reducing corrosion or slagging related problems. The following products have been obtained, characterised and evaluated: 1) Brewery draff 2) Danish de-gassed manure 3) Paper sludge 4) Moulding sand 5) Spent bleaching earth 6) Anorthosite 7) Sand 8) Clay-sludge. Most of the above alternative additive candidates are deemed unsuitable due to insufficient chemical effect and/or expensive requirements for pre-treatment (such as drying and transportation). 3 products were selected for full-scale testing: de-gassed manure, spent bleaching earth and clay slugde. The full scale tests were undertaken at the biomass-fired power stations in Koege, Slagelse and Ensted. Spent bleaching earth (SBE) and clay sludge were the only tested additive candidates that had a proven ability to react with KCl, to thereby reduce Cl-concentrations in deposits, and reduce the deposit flux to superheater tubes. Their performance was shown to nearly as good as commercial additives. De-gassed manure, however, did not evaluate positively due to inhibiting effects of Ca in the manure. Furthermore, de-gassed manure has a high concentration of heavy metals, which imposes a financial burden with regard to proper disposal of the ash by-products. Clay-sludge is a wet clay slurring, and drying and transportation of this product entails substantial costs. Spent bleaching does not require much pre-treatment and is therefore the most promising alternative additive. On the other hand, bleaching earth contains residual plant oil which means that a range of legislation relating to waste combustion comes into play. Not least a waste combustion fee of 330 DKK/tonne. For all alternative (and commercial) additives disposal costs of the increase ash by-products represents a significant cost. This is

    1975-01-01

    The polymers used in plastics are generally harmless. However, they are rarely used in pure form. In almost all commercial plastics, they are "compounded" with monomeric ingredients to improve their processing and end-use performance. In order of total volume used, these monomeric additives may be classified as follows: reinforcing fibers, fillers, and coupling agents; plasticizers; colorants; stabilizers (halogen stabilizers, antioxidants, ultraviolet absorbers, and biological preservatives); processing aids (lubricants, others, and flow controls); flame retardants, peroxides; and antistats. Some information is already available, and much more is needed, on potential toxicity and safe handling of these additives during processing and manufacture of plastics products. PMID:1175566

Pendapatan yang diperoleh dari kegiatan budidaya ikan mas telah memicu terjadinya percepatan laju pembangunan yaitu dengan adanya perubahan lansekap dari petak-petak sawah menjadi kolam-kolam ikan. Keterbatasan lingkungan tampaknya tidak dipertimbangkan, karena hasil panen yang tinggi atau keuntungan usaha menjadi tujuan pokok perluasan atau pun intensifikasi kegiatan budidaya ikan mas. Mengingat peran penting pembudidaya ikan skala kecil di rantai produksi ikan mas di Jawa Barat, kami melakukan kajian terhadap daya lenting mereka dalam menghadapi tantangan mengelola ekosistem budidaya ikan air tawar. Dengan memanfaatkan metoda pengamatan-partisipatif dan wawancara mendalam, data dan informasi dari para pelaku budidaya ikan mas skala kecil di Kecamatan Pagaden Kabupaten Subang Jawa Barat ditelusur. Analisis data dilakukan secara deskriptif untuk memberikan ruang artikulatif dalam mengurai fenomena lapangan yang dirangkum dalam kerangka pikir sosio-ekologi. Dapat disimpulkan bahwa meskipun mereka memiliki kearifan lokal tersendiri dalam membudidayakan ikan mas di kolam air tawar, ketergantungan yang tinggi pada kegiatan akuakultur ikan mas, telah sampai pada situasi diperlukannya pengenalan teknologi budidaya yang ramah lingkungan. Pengenalan teknologi tersebut seyogyanya disertai strategi pendampingan yang sesuai dengan kebutuhan dan karakter sosial-budaya para pembudidaya ikan mas skala kecil. Hal ini perlu dijadikan agenda pemerintah daerah untuk diterapkan demi keberlanjutan pengelolaan ekosistem akuakultur di Subang – Jawa Barat.

    2001-01-01

    Since the end of the cold war a series of events has changed the circumstances and requirements of the safeguards system. The discovery of a clandestine nuclear weapons program in Iraq, the continuing difficulty in verifying the initial report of Democratic People's Republic of Korea upon entry into force of their safeguards agreement, and the decision of the South African Government to give up its nuclear weapons program and join the Treaty on the Non-Proliferation of Nuclear Weapons have all played a role in an ambitious effort by IAEA Member States and the Secretariat to strengthen the safeguards system. A major milestone in this effort was reached in May 1997 when the IAEA Board of Governors approved a Model Protocol Additional to Safeguards Agreements. The Model Additional Protocol was negotiated over a period of less than a year by an open-ended committee of the Board involving some 70 Member States and two regional inspectorates. The IAEA is now in the process of negotiating additional protocols, State by State, and implementing them. These additional protocols will provide the IAEA with rights of access to information about all activities related to the use of nuclear material in States with comprehensive safeguards agreements and greatly expanded physical access for IAEA inspectors to confirm or verify this information. In conjunction with this, the IAEA is working on the integration of these measures with those provided for in comprehensive safeguards agreements, with a view to maximizing the effectiveness and efficiency, within available resources, the implementation of safeguards. Details concerning the Model Additional Protocol are given. (author)

    Boiling Water Reactors (BWRs) have been injecting zinc into the primary coolant via the reactor feedwater system for over 25 years for the purpose of controlling primary system radiation fields. The BWR zinc injection process has evolved since the initial application at the Hope Creek Nuclear Station in 1986. Key transitions were from the original natural zinc oxide (NZO) to depleted zinc oxide (DZO), and from active zinc injection of a powdered zinc oxide slurry (pumped systems) to passive injection systems (zinc pellet beds). Zinc addition has continued through various chemistry regimes changes, from normal water chemistry (NWC) to hydrogen water chemistry (HWC) and HWC with noble metals (NobleChem™) for mitigation of intergranular stress corrosion cracking (IGSCC) of reactor internals and primary system piping. While past reports published by the Electric Power Research Institute (EPRI) document specific industry experience related to these topics, the Zinc Sourcebook was prepared to consolidate all of the experience gained over the past 25 years. The Zinc Sourcebook will benefit experienced BWR Chemistry, Operations, Radiation Protection and Engineering personnel as well as new people entering the nuclear power industry. While all North American BWRs implement feedwater zinc injection, a number of other BWRs do not inject zinc. This Sourcebook will also be a valuable resource to plants considering the benefits of zinc addition process implementation, and to gain insights on industry experience related to zinc process control and best practices. This paper presents some of the highlights from the Sourcebook. (author)

  5. Reinforcement with fluoroplastic additives

    1991-05-01

    The use of high molecular weight polytetrafluoroethylene (PTFE) as a reinforcing additive to improve the tear strength of elastomers was studied in silicone rubber by the mid-1950s and in fluoroelastomers by the late-1960s. Although the PTFE is added as a powder, the shear developed during compounding into an elastomer fibrillates the power into a continuous network of nodes and fibers. This network structure effectively reinforces elastomers but it also leads to distortion of finished parts and unacceptably high hardness and modulus of vulcanizates. A new high molecular weight TFE/HFP fluoroplastic micropowder has recently been developed (Teflon MP1500, Du Pont) which forms short fibers, ribbons or platelets when compounded with sufficient shear into elastomers. The controlled structure developed during compounding allows high levels of incorporation of the micropowder into elastomers with uniform dispersion and results in significant improvements in tear strength and abrasion resistance, as well as reduced coefficients of friction.

    The additive is for a raw sewage treatment process of the type where settling tanks are used for the purpose of permitting the suspended matter in the raw sewage to be settled as well as to permit adsorption of the dissolved contaminants in the water of the sewage. The sludge, which settles down to the bottom of the settling tank is extracted, pyrolyzed and activated to form activated carbon and ash which is mixed with the sewage prior to its introduction into the settling tank. The sludge does not provide all of the activated carbon and ash required for adequate treatment of the raw sewage. It is necessary to add carbon to the process and instead of expensive commercial carbon, coal is used to provide the carbon supplement.

    Superconducting radio frequency cavities provide an ultra-low dissipative environment, which has enabled fundamental investigations in quantum mechanics, materials properties, and the search for new particles in and beyond the standard model. However, resonator designs are constrained by limitations in conventional machining techniques. For example, current through a seam is a limiting factor in performance for many waveguide cavities. Development of highly reproducible methods for metallic parts through additive manufacturing, referred to colloquially as 3D printing\\x9D, opens the possibility for novel cavity designs which cannot be implemented through conventional methods. We present preliminary investigations of superconducting cavities made through a selective laser melting process, which compacts a granular powder via a high-power laser according to a digitally defined geometry. Initial work suggests that assuming a loss model and numerically optimizing a geometry to minimize dissipation results in modest improvements in device performance. Furthermore, a subset of titanium alloys, particularly, a titanium, aluminum, vanadium alloy (Ti - 6Al - 4V) exhibits properties indicative of a high kinetic inductance material. This work is supported by LDRD 16-SI-004.

    Full Text Available O polímero termofixo conhecido comercialmente como CR-39 é amplamente utilizado em aplicações ópticas. No processo convencional, utilizam-se peróxidos orgânicos como termo-iniciadores da polimerização. Devido à natureza altamente exotérmica da reação de polimerização, esse processo deve ser conduzido em baixas temperaturas e ocorre lentamente para se evitar defeitos, especialmente no caso de se produzir lentes mais espessas. A utilização de foto-iniciação com ultravioleta, por exemplo, permite uma polimerização mais rápida e reduz os efeitos exotérmicos da reação; por outro lado, a alta taxa de reação e a rápida liberação de calor podem causar defeitos nas lentes. O conhecimento dos perfis de temperatura e de conversão dentro do material durante a polimerização é essencial para se otimizar os processos, tanto termo quanto foto-iniciado. Neste trabalho são estudados modelos para simular esses processos. Os balanços de massa e de energia resultam em equações diferenciais parciais que são resolvidas através do método da Colocação Ortogonal e do método de Runge-Kutta-Gill.

    Food additives are an integral part of the modern food system, but opinion polls showing most Europeans have worries about them imply an urgent need for ethical analysis of their use. The existing literature on food ethics, safety assessment and animal testing. Food additives provide certain advantages in terms of many people's lifestyles. There are disagreements about the appropriate application of the precautionary principle and of the value and ethical validity of animal tests in assessing human safety. Most consumers have a poor understanding of the relative benefits and risks of additives, but concerns over food safety and animal testing remain high. Examining the impacts of food additives on consumer sovereignty, consumer health and on animals used in safety testing should allow a more informed debate about their appropriate uses.

    2013-02-01

    Food additives have been used throughout history to perform specific functions in foods. A comprehensive framework of legislation is in place within Europe to control the use of additives in the food supply and ensure they pose no risk to human health. Further to this, exposure assessments are regularly carried out to monitor population intakes and verify that intakes are not above acceptable levels (acceptable daily intakes). Young children may have a higher dietary exposure to chemicals than adults due to a combination of rapid growth rates and distinct food intake patterns. For this reason, exposure assessments are particularly important in this age group. The paper will review the use of additives and exposure assessment methods and examine factors that affect dietary exposure by young children. One of the most widely investigated unfavourable health effects associated with food additive intake in preschool-aged children are suggested adverse behavioural effects. Research that has examined this relationship has reported a variety of responses, with many noting an increase in hyperactivity as reported by parents but not when assessed using objective examiners. This review has examined the experimental approaches used in such studies and suggests that efforts are needed to standardise objective methods of measuring behaviour in preschool children. Further to this, a more holistic approach to examining food additive intakes by preschool children is advisable, where overall exposure is considered rather than focusing solely on behavioural effects and possibly examining intakes of food additives other than food colours.

    2017-02-01

    Individual additive manufacturing of optical systems based on 3D Printing offers varied possibilities in design and usage. In addition to the additive manufacturing procedure, the usage of tunable lenses allows further advantages for intelligent optical systems. Our goal is to bring the advantages of additive manufacturing together with the huge potential of tunable lenses. We produced tunable lenses as a bundle without any further processing steps, like polishing. The lenses were designed and directly printed with a 3D Printer as a package. The design contains the membrane as an optical part as well as the mechanical parts of the lens, like the attachments for the sleeves which contain the oil. The dynamic optical lenses were filled with an oil. The focal length of the lenses changes due to a change of the radius of curvature. This change is caused by changing the pressure in the inside of the lens. In addition to that, we designed lenses with special structures to obtain different areas with an individual optical power. We want to discuss the huge potential of this technology for several applications. Further, an appropriate controlling system is needed. Wéll show the possibilities to control and regulate the optical power of the lenses. The lenses could be used for illumination tasks, and in the future, for individual measurement tasks. The main advantage is the individuality and the possibility to create an individual design which completely fulfills the requirements for any specific application.

    This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of various food additives, including flavouring agents, with a view to concluding as to safety concerns and to preparing specifications for identity and purity. The first part of the report contains a general discussion of the principles governing the toxicological evaluation of and assessment of dietary exposure to food additives, including flavouring agents. A summary follows of the Committee’s evaluations of technical, toxicological and dietary exposure data for 10 food additives (Allura Red AC; carob bean gum; lutein esters from Tagetes erecta; octenyl succinic acid (OSA)– modified gum arabic; pectin; Quinoline Yellow; rosemary extract; steviol glycosides; tartrazine; and xanthan gum) and five groups of flavouring agents (alicyclic, alicyclic-fused and aromatic-fused ring lactones; aliphatic and aromatic amines and amides; aliphatic secondary alcohols, ketones and related esters; cinnamyl alcohol and related substances; and tetrahydrofuran and furanone derivatives). Specifications for the following food additives were revised: aspartame; cassia gum; citric and fatty acid esters of glycerol (CITREM); modified starches; octanoic acid; starch sodium octenyl succinate; and total colouring matters. Annexed to the report are tables summarizing the Committee’s recommendations for dietary exposures to and toxicological evaluations of all of the food additives, including flavouring agents, considered at this meeting.

    The purpose is to evaluate the psychometric properties of reliability and discriminant validity of the Brazilian Portuguese versions of two instruments used in the diagnosis of interstitial cystitis (IC): "The Interstitial Cystitis Symptom Index and Problem Index" (The O'Leary-Sant), and "Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale". Three groups of patients were examined: a study group (subjects with IC), control group 1 (individuals with at least one IC symptom), and control group 2 (subjects without IC symptoms). Test-retest stability was evaluated at intervals of 3 to 7 days in the study group. Discriminant validity was examined in all three groups. The intraclass correlation coefficient (ICC) [95% confidence interval (CI)] results were 0.56 (range, 0.21-0.78) for The O'Leary-Sant Symptom Index, 0.48 (range, 0.10-0.73) for The O'Leary-Sant Problem Index, and 0.49 (range, 0.12-0.74) for the PUF. To analyze discriminant validity between groups, we used Fisher's exact test and odd ratio (OR) to identify differences. We obtained a P value<0.0001, which indicated that the null hypothesis was rejected; in other words, there was evidence that at least two different groups were compared to the proportion of patients with IC. The analyzed instruments did not reach appropriate values for reliability. Future studies are needed to analyze the psychometric measures of these instruments on a larger sample of patients with IC.

    The structure of insulin, a glucose homeostasis-controlling hormone, is highly conserved in all vertebrates and stabilized by three disulfide bonds. Recently, we designed a novel insulin analogue containing a fourth disulfide bond located between positions A10-B4. The N-terminus of insulin's B......-chain is flexible and can adapt multiple conformations. We examined how well disulfide bond predictions algorithms could identify disulfide bonds in this region of insulin. In order to identify stable insulin analogues with additional disulfide bonds, which could be expressed, the Cβ cut-off distance had...... in comparison to analogues with additional disulfide bonds that were more difficult to predict. In contrast, addition of the fourth disulfide bond rendered all analogues resistant to fibrillation under stress conditions and all stable analogues bound to the insulin receptor with picomolar affinities.

    Additive manufacturing, more commonly known as 3-D printing, has become a ubiquitous tool in science for its precise control over mechanical design. For additive manufacturing to work, a 3-D structure is split into thin 2D slices, and then different physical properties, such as photo-polymerization or melting, are used to grow the sequential layers. The level of control allows not only for devices to be made with a variety of materials: e.g. plastics, metals, and quantum dots, but to also have finely controlled structures leading to other novel properties. While 3-D printing is widely used by hobbyists for making models, it also has industrial applications in structural engineering, biological tissue scaffolding, customized electric circuitry, fuel cells, security, and more.

    1997-01-01

    To obtain qualitative dolomitic lime the optimum calcination temperature of dolomite containing about 9 % of clayey substances is 900 deg C. The mechanical strength of dolomitic lime containing 30 % of brick waste additive after 6-9 months of hardening is 1.4-1.5 times higher than that of samples without hydraulic additive, for calcium lime - 2.2-2.6 times higher. Generally the mechanical strength of dolomitic lime is higher than that one of calcium lime. It can be explained by the active role of MgO in the hydration and hardening processes of dolomitic lime. Xray diffraction phase analysis was performed by X-ray diffractometer DPON-3M with Cu-K α emission filter

    The chemical rate constants for the addition of the muonium atom (Mu) across the vinyl double bonds of acrylamide, acrylic acid, acrylonitrile, methylmethacrylate, and styrene were determined in aqueous solution; they are, respectively, ksub(m) = 1.9x10 10 M -1 s -1 ,1.6x10 10 M -1 s -1 , 1.1x10 10 M -1 s -1 , 9.5x10 9 M -1 s -1 , and 1.1 x 10 9 M -1 . Since muonium can be considered a very light isotope of hydrogen, the kinetic isotope effects, ksub(M)/ksub(H), for acrylamide (1.1) and acrylonitrile (2.8) were calculated. The muonium rate constants of these monomers are also compared to those of hydroxyl and methyl radical addition where available. The muonium substituted free radical formed by reaction with styrene is represented by two peaks in the Fourier Transform of the μSR spectrum at 500, 1500 and 2500 G with a hyperfine coupling constant of 213.5 MHz. This spectrum shows that Mu addition to styrene occurs at the vinyl bond only and not at the benzene ring

    Two-sided matchings are an important theoretical tool used to model markets and social interactions. In many real life problems the utility of an agent is influenced not only by their own choices, but also by the choices that other agents make. Such an influence is called an externality. Whereas...... fully expressive representations of externalities in matchings require exponential space, in this paper we propose a compact model of externalities, in which the influence of a match on each agent is computed additively. In this framework, we analyze many-to-many and one-to-one matchings under neutral...

    The discovery of a Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well-established and consistent with many measurements, it is not capable to solely explain some observations. Many extension addressing this fact introduce additional Higgs-like bosons which can be either neutral, singly-charged or even doubly-charged. The current status of searches based on data of the ATLAS and CMS experiments at the LHC are presented. No indications for such particles were however found.

    Currently, helium is obtained through separation from natural gas. The current industrial process incurs significant costs and requires large energy resources to successfully achieve separation. Through utilizing Additive Manufacturing (AM) technologies it is possible to reduce both of these burdens when refining helium gas. The ability to engineer porosity levels within Inconel 718 discs for controlled separation of helium from natural gas was investigated. Arrays of samples fabricated using the electron beam melting process were analyzed for their relative porosity density. Based upon the measurements, full scale discs were fabricated, and subsequently tested to determine their effectiveness in separating helium from liquefied natural gas.

  13. Public contracts by negotiated procedure in cases of urgency – a new interpretation of the legal basis in light of experiences with organization of the 2012 European Football Championships

    Directory of Open Access Journals (Sweden)

    Krzysztof Horubski

    2013-06-01

    Full Text Available The negotiated procedure without publication of a contract notice is a special procedure for awarding public procurement contracts which departs from the obligation imposed on contracting authorities of respecting the freedoms of the internal market and rules of competition. The procedure may be applied in exceptional situations of extreme urgency resulting from an event which could not be foreseen. The current judicature of the Court of Justice of the EU provides interpretations of the legal basis for application of the procedure in specific cases. However, it does not address the issue of whether it is possible to regard improper performance of contractual obligations as unpredictable. It does not provide broader considerations concerning the form of regulations on the procedure of awarding public interest contracts either. These issues were subject to analysis in one of the resolutions of the National Appeal Chamber (KIO – the Polish authority issuing decisions in matters related to public procurement contracts. In resolution KIO/KD 58/10 of 6 August 2010, KIO assessed the correctness of the application of the negotiated procedure for changing the contractor of the Municipal Stadium in Wrocław in the run-up to the 2012 European Football Championships. KIO found that the significant delay in construction of the facility was unpredictably exceptional, and significantly threatened the timeliness of commissioning the facility, which resulted in termination of the agreement by the contracting authority. The resolution also included an assessment allowing for the position that such a situation was exceptional due to the scale of the threat to the public interest, including the commercial interest of the contracting authority, stemming from a lack of immediate performance of the contract if it resulted in disproportionate consequences for a specific community. The issue of acceptance of such an interpretation by EU institutions remains unresolved.

  14. Additive manufacturing of RF absorbers

    Mills, Matthew S.

    The ability of additive manufacturing techniques to fabricate integrated electromagnetic absorbers tuned for specific radio frequency bands within structural composites allows for unique combinations of mechanical and electromagnetic properties. These composites and films can be used for RF shielding of sensitive electromagnetic components through in-plane and out-of-plane RF absorption. Structural composites are a common building block of many commercial platforms. These platforms may be placed in situations in which there is a need for embedded RF absorbing properties along with structural properties. Instead of adding radar absorbing treatments to the external surface of existing structures, which adds increased size, weight and cost; it could prove to be advantageous to integrate the microwave absorbing properties directly into the composite during the fabrication process. In this thesis, a method based on additive manufacturing techniques of composites structures with prescribed electromagnetic loss, within the frequency range 1 to 26GHz, is presented. This method utilizes screen printing and nScrypt micro dispensing to pattern a carbon based ink onto low loss substrates. The materials chosen for this study will be presented, and the fabrication technique that these materials went through to create RF absorbing structures will be described. The calibration methods used, the modeling of the RF structures, and the applications in which this technology can be utilized will also be presented.

    Additive manufacturing (3D printing) has found many applications in healthcare including fabrication of biomaterials as well as bioprinting of tissues and organs. Additively manufactured (AM) biomaterials may possess arbitrarily complex micro-architectures that give rise to novel mechanical, physical, and biological properties. The mechanical behavior of such porous biomaterials including their quasi-static mechanical properties and fatigue resistance is not yet well understood. It is particularly important to understand the relationship between the designed micro-architecture (topology) and the resulting mechanical properties. The current special issue is dedicated to understanding the mechanical behavior of AM biomaterials. Although various types of AM biomaterials are represented in the special issue, the primary focus is on AM porous metallic biomaterials. As a prelude to this special issue, this editorial reviews some of the latest findings in the mechanical behavior of AM porous metallic biomaterials so as to describe the current state-of-the-art and set the stage for the other studies appearing in the issue. Some areas that are important for future research are also briefly mentioned. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Oak Ridge National Laboratory (ORNL) is leveraging decades of experience in neutron characterization of advanced materials together with resources such as the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR) shown in Fig. 1 to solve challenging problems in additive manufacturing (AM). Additive manufacturing, or three-dimensional (3-D) printing, is a rapidly maturing technology wherein components are built by selectively adding feedstock material at locations specified by a computer model. The majority of these technologies use thermally driven phase change mechanisms to convert the feedstock into functioning material. As the molten material cools and solidifies, the component is subjected to significant thermal gradients, generating significant internal stresses throughout the part (Fig. 2). As layers are added, inherent residual stresses cause warping and distortions that lead to geometrical differences between the final part and the original computer generated design. This effect also limits geometries that can be fabricated using AM, such as thin-walled, high-aspect- ratio, and overhanging structures. Distortion may be minimized by intelligent toolpath planning or strategic placement of support structures, but these approaches are not well understood and often "Edisonian" in nature. Residual stresses can also impact component performance during operation. For example, in a thermally cycled environment such as a high-pressure turbine engine, residual stresses can cause components to distort unpredictably. Different thermal treatments on as-fabricated AM components have been used to minimize residual stress, but components still retain a nonhomogeneous stress state and/or demonstrate a relaxation-derived geometric distortion. Industry, federal laboratory, and university collaboration is needed to address these challenges and enable the U.S. to compete in the global market. Work is currently being conducted on AM technologies at the ORNL

    A problem has been raised on the necessity to substitute the linear-nonthreshold hypothesis as a paradigm of radiation hygiene for the hypothesis of the biological effectiveness of ionizing irradiations. A comparison of the methodological substantiation for both hypotheses and a conception of 'acceptable risk' has been carried out. It is suggested that the possibility of theoretical substantiation of safety standards for the radiational factor on the basis of adatational hypothesis be acknowledged instead of the linear - nonthreshold conception which has lost its historic significance

    Full Text Available In the context of transforming a part of Serbian anthropology into social theoretic management of identity, I suggest both comparative historiographic and ethnographic learning from societies with similar post-colonial experience, with the aim to include the discipline into an urgent defense of Serbia and Belgrade from further ethno-profiteering interests of elites in/from outer territories, left over on the ruins of our ill judged, resource incompatible, exaggerated or immoral twentieth century adventures. Serbian anthropology, written by anthropologists to whom Serbia and Belgrade are "homeland" by origin or civilized choice, should play the key role in the defense of Serbian citizens from the interest of elites in/from the outer "homelands", particularly by revealing the processes for which it is, as a discipline, most expert at – the professionalization of ethnicity, interactive and hybrid nature of identity, instrumental nature of tradition and the identity politics in general. Having in mind the latest attempt, a particularly successful one, conducted by the end of the 20th and the beginning of the 21st century that the lives, health, well-being, dignity and future of persons born in and loyal to the interest of Serbia and Belgrade, in large scale, thoroughly and long term be sacrificed and dedicated to the interests of ethno-profiteering elites in/from outer territories, in this article I point to the possibility to, along with the comparative learning from the above mentioned post-colonial experiences, delicate experiences of urgent anthropology be applied as well as the rich tradition of collective research. This text analyzes the results of first such research, that represenst the initial, praiseworthy and a brave step in the wise striving to engage social sciences and humanities in a search of expert and not mythical/daily-political solutions of the key problem of the Serbian nation – that of how to settle the interests of the elites of population in/from outer territories sufficiently so that their local/regional problems or private interests can never again be treated as the national interest, nor be used as reasons for (selfdestruction and(selfhumiliation of Serbia and Belgrade.

    Full Text Available Resumen Las crisis hipertensivas son un conjunto de situaciones clínicas de variada gravedad y pronóstico. Las diferencias entre urgencias y emergencias hipertensivas radican en la existencia o no de riesgo vital por afectación de órganos diana, más que por los niveles de presión arterial. Las urgencias hipertensivas no suelen comportar riesgo vital inmediato por lo que el tratamiento puede iniciarse, incluso completarse, en el medio extrahospitalario. Las emergencias hipertensivas son situaciones clínicas muy graves que requieren asistencia hospitalaria. Ante un paciente con hipertensión grave, asintomático o con síntomas inespecíficos debe adoptarse una actitud terapéutica prudente. La primera medida será comprobar las cifras de presión arterial con tomas repetidas de la misma y tratar los posibles factores desencadenantes. El objetivo del tratamiento de las urgencias hipertensivas es tanto obtener una reducción de las cifras de presión arterial (al menos un 20% de las cifras basales como evitar reducciones bruscas y/o excesivas de la misma. En las urgencias hipertensivas no deberían utilizarse fármacos de acción rápida por el riesgo de accidentes isquémicos y utilizar fármacos con vida media más larga. El riesgo cardiovascular de estos pacientes es superior al de los hipertensos que no sufren una crisis hipertensiva. En las emergencias hipertensivas la elección del fármaco deberá individualizarse. La vía parenteral es la forma habitual de la administración de fármacos.

    BACKGROUND: Screening programmes for type 2 diabetes inevitably find more individuals at high risk for diabetes than people with undiagnosed prevalent disease. While well established guidelines for the treatment of diabetes exist, less is known about treatment or prevention strategies...... for individuals found at high risk following screening. In order to make better use of the opportunities for primary prevention of diabetes and its complications among this high risk group, it is important to quantify diabetes progression rates and to examine the development of early markers of cardiovascular...... disease and microvascular diabetic complications.

  5. Additivity of entropic uncertainty relations

    2018-03-01

    Full Text Available We consider the uncertainty between two pairs of local projective measurements performed on a multipartite system. We show that the optimal bound in any linear uncertainty relation, formulated in terms of the Shannon entropy, is additive. This directly implies, against naive intuition, that the minimal entropic uncertainty can always be realized by fully separable states. Hence, in contradiction to proposals by other authors, no entanglement witness can be constructed solely by comparing the attainable uncertainties of entangled and separable states. However, our result gives rise to a huge simplification for computing global uncertainty bounds as they now can be deduced from local ones. Furthermore, we provide the natural generalization of the Maassen and Uffink inequality for linear uncertainty relations with arbitrary positive coefficients.

    A test artifact, intended for standardization, is proposed for the purpose of evaluating the performance of additive manufacturing (AM) systems. A thorough analysis of previously proposed AM test artifacts as well as experience with machining test artifacts have inspired the design of the proposed test artifact. This new artifact is designed to provide a characterization of the capabilities and limitations of an AM system, as well as to allow system improvement by linking specific errors measured in the test artifact to specific sources in the AM system. The proposed test artifact has been built in multiple materials using multiple AM technologies. The results of several of the builds are discussed, demonstrating how the measurement results can be used to characterize and improve a specific AM system. PMID:26601039

    The additive manufacturing of small diameter polypropylene microfibers is described, achieved using a technique termed melt electrospinning writing. Sequential fiber layering, which is important for accurate three-dimensional fabrication, was achieved with the smallest fiber diameter of 16.4±0.2μm obtained. The collector speed, temperature and melt flow rate to the nozzle were optimized for quality and minimal fiber pulsing. Of particular importance to the success of this method is appropriate heating of the collector plate, so that the electrostatically drawn filament adheres during the direct-writing process. By demonstrating the direct-writing of polypropylene, new applications exploiting the favorable mechanical, stability and biocompatible properties of this polymer are envisaged. Copyright © 2017.

    Intensification of industrial production, increasing citizens’ living standards, expanding the consumer assortment mean in the production - consumption cycle a constantly increasing occurrence of waste material, which by its very nature must be considered as a source of useful raw materials in all branches of human activity. In addition to strict legislative requirements, a number of circumstances characterize waste management. It is mainly extensive transport associated with the handling and storage of large volumes of substances with a large assortment of materials (substances of all possible physical and chemical properties) and high demands on reliability and time coordination of follow-up processes. Considerable differences in transport distances, a large number of sources, processors and customers, and not least seasonal fluctuations in waste and strong price pressures cannot be overlooked. This highlights the importance of logistics in waste management. Soils that are contaminated with oil and petroleum products are hazardous industrial waste. Methods of industrial waste disposal are landfilling, biological processes, thermal processes and physical and chemical methods. The paper focuses on the possibilities of degradation of oil pollution, in particular biodegradation by bacteria, which is relatively low-cost among technologies. It is necessary to win the fight with time so that no ground water is contaminated. We have developed two additional devices to help reduce oil accident of smaller ranges. In the case of such an oil accident, it is necessary to carry out the permeability test of contaminated soil in time and, on this basis, to choose the technology appropriate to the accident - either in-sit biodegradation - at the site of the accident, or on-sit - to remove the soil and biodegrade it on the designated deposits. A special injection drill was developed for in-sit biodegradation, tossing and aeration equipment of the extracted soil was developed for

    Tech Traders Inc. sought assistance developing low-cost, highly effective coatings and paints that created useful thermal reflectance and were safe and non-toxic. In cooperation with a group of engineers at Kennedy Space Center., Tech Traders created Insuladd, a powder additive made up of microscopic, inert gas-filled, ceramic microspheres that can be mixed into ordinary interior or exterior paint, allowing the paint to act like a layer of insulation. When the paint dries, this forms a radiant heat barrier, turning the ordinary house paint into heat-reflecting thermal paint. According to Tech Traders, the product works with all types of paints and coatings and will not change the coverage rate, application, or adhesion of the paint. Other useful applications include feed storage silos to help prevent feed spoilage, poultry hatcheries to reduce the summer heat and winter cold effects, and on military vehicles and ships. Tech Traders has continued its connection to the aerospace community by recently providing Lockheed Martin Corporation with one of its thermal products for use on the F-22 Raptor.

  12. Dynamics of ultrasonic additive manufacturing.

    Hehr, Adam; Dapino, Marcelo J

    2017-01-01

    Ultrasonic additive manufacturing (UAM) is a solid-state technology for joining similar and dissimilar metal foils near room temperature by scrubbing them together with ultrasonic vibrations under pressure. Structural dynamics of the welding assembly and work piece influence how energy is transferred during the process and ultimately, part quality. To understand the effect of structural dynamics during UAM, a linear time-invariant model is proposed to relate the inputs of shear force and electric current to resultant welder velocity and voltage. Measured frequency response and operating performance of the welder under no load is used to identify model parameters. Using this model and in-situ measurements, shear force and welder efficiency are estimated to be near 2000N and 80% when welding Al 6061-H18 weld foil, respectively. Shear force and welder efficiency have never been estimated before in UAM. The influence of processing conditions, i.e., welder amplitude, normal force, and weld speed, on shear force and welder efficiency are investigated. Welder velocity was found to strongly influence the shear force magnitude and efficiency while normal force and weld speed showed little to no influence. The proposed model is used to describe high frequency harmonic content in the velocity response of the welder during welding operations and coupling of the UAM build with the welder.

    Additive manufacturing (AM) has the potential to create geometrically complex parts that require a high degree of customization, using less material and producing less waste. Recent studies have shown that AM can be an economically viable option for use by the industry, yet there are some inherent challenges associated with AM for wider acceptance. The lack of standards in AM impedes its use for parts production since industries primarily depend on established standards in processes and material selection to ensure the consistency and quality. Inability to compare AM performance against traditional manufacturing methods can be a barrier for implementing AM processes. AM process sustainability has become a driver due to growing environmental concerns for manufacturing. This has reinforced the importance to understand and characterize AM processes for sustainability. Process characterization for sustainability will help close the gaps for comparing AM performance to traditional manufacturing methods. Based on a literature review, this paper first examines the potential environmental impacts of AM. A methodology for sustainability characterization of AM is then proposed to serve as a resource for the community to benchmark AM processes for sustainability. Next, research perspectives are discussed along with relevant standardization efforts.

    Additive manufacturing (AM), also known as 3D-printing, has been shifting from a novelty prototyping paradigm to a legitimate manufacturing tool capable of creating components for highly complex engineered products. An emerging AM technology for producing metal parts is the laser powder bed fusion (L-PBF) process; however, industry manufacturing specifications and component design practices for L-PBF have not yet been established. Solar Turbines Incorporated (Solar), an industrial gas turbine manufacturer, has been evaluating AM technology for development and production applications with the desire to enable accelerated product development cycle times, overall turbine efficiency improvements, and supply chain flexibility relative to conventional manufacturing processes (casting, brazing, welding). Accordingly, Solar teamed with EWI on a joint two-and-a-half-year project with the goal of developing a production L-PBF AM process capable of consistently producing high-nickel alloy material suitable for high temperature gas turbine engine fuel injector components. The project plan tasks were designed to understand the interaction of the process variables and their combined impact on the resultant AM material quality. The composition of the high-nickel alloy powders selected for this program met the conventional cast Hastelloy X compositional limits and were commercially available in different particle size distributions (PSD) from two suppliers. Solar produced all the test articles and both EWI and Solar shared responsibility for analyzing them. The effects of powder metal input stock, laser parameters, heat treatments, and post-finishing methods were evaluated. This process knowledge was then used to generate tensile, fatigue, and creep material properties data curves suitable for component design activities. The key process controls for ensuring consistent material properties were documented in AM powder and process specifications. The basic components of the project

    A program for helping homeless individuals in winter is implemented from November 1(st) to March 31(st) each year in France. Its aim is to prevent morbidity and mortality in this population during cold spells and periods of severe cold. A health surveillance system of the homeless population in the Paris area has been proposed to evaluate the effectiveness of the program and to alert decision-makers if an unusual increase in cold-weather effects is observed. The goal of this study was the creation of an indicator for the proposed surveillance system based on emergency department activity in the Paris area (Oscour(®) Network - Organisation de la surveillance coordonnée des urgences). The winter 2007-2008 computer medical files of 11 emergency departments in the Paris area were examined to confirm diagnosis and ascertain patient-homelessness for each patient visit which was selected from the Oscour(®) database by the patient chief-complaint or diagnosis code referring to hypothermia or frostbites. The proposed indicator is based on the maximization of three criteria: the positive predictive value, the proportion of people identified as being homeless and the number of emergency department visits. A Shewhart control chart was applied to the indicator for the four winters between 2005 and 2009 in the Paris area. Values beyond the statistical threshold would indicate a need for an adjustment to the program strategy. Two hundred and sixteen medical files were analyzed. An indicator was created, "number of emergency department visits of 15 to 69-years-old persons with chief-complaint or diagnosis code referring to hypothermia". It had a positive predictive value estimated near 85 % and identified 61.7 % people as being homeless. In the winter of 2008-2009, the statistical threshold was reached in December during the first cold spell, and again at the beginning of January during a period of severe cold. Our results support the use of this health indicator

    Bahna, Sami L; Burkhardt, Joshua G

    2018-01-01

    To provide a brief summary on food additives and to outline a practical approach for evaluating subjects suspected of having reactions to food additives. Information was derived from selected reviews and original articles published in peer-reviewed journals, supplemented by the clinical experience of the authors. Priority was given to studies that used blinded, placebo controlled, oral challenges to confirm adverse reactions to food additives. In addition, selected, appropriately evaluated case reports were included. A large number of food additives are widely used in the food industry. Allergic reactions to additives seem to be rare but are very likely underdiagnosed, primarily due to a low index of suspicion. A wide variety of symptoms to food additives have been reported, but a cause-and-effect relationship has not been well documented in the majority of cases. Reactions to food additives should be suspected in patients who report symptoms related to multiple foods or to a certain food when commercially prepared but not when home made. It is also prudent to investigate food additives in subjects considered to have "idiopathic" reactions. Except for a limited number of natural additives, there is a small role for skin tests or in vitro testing. Oral challenge, in stages, with commonly used additives is the definitive procedure for detecting the offending agent. Once the specific additive is identified, management is strict avoidance, which can be difficult.

    Directory of Open Access Journals (Sweden)

    Raul de Camargo Vianna Filho

    2000-10-01

    Full Text Available Objetivo: Avaliar pela biomicrospia ultra-sônica (UBM o posicionamento, em relação ao sulco ciliar, das alças de lentes intra-oculares (LIO, em uma técnica de fixação escleral, avaliando-se também se dois pontos de fixação são suficientes para que não haja inclinação da parte óptica. Métodos: Dezesseis olhos afácicos foram submetidos a implante LIO por uma mesma técnica de fixação escleral, realizados por um mesmo cirurgião. Um mês após a cirurgia, o posicionamento das alças das LIO foram avaliados pelo UBM, assim como distâncias entre as LIO e córnea. Os resultados foram submetidos a testes estatísticos. Resultados: Das 32 alças fixadas à esclera, oito estavam localizadas no sulco ciliar e 24 fora deste. Não houve diferença estatística nas distâncias entre LIO e córnea para alças posicionadas no sulco ciliar quando comparadas àquelas localizadas fora do sulco. Isto sugere que, além da distância ao limbo que se transfixa a esclera, outros fatores devem estar associados ao posicionamento da alça no sulco ciliar. As medidas LIO -- córnea realizadas na periferia das LIO às 3, 6, 9, e 12 horas foram semelhantes, mostrando que dois pontos de fixação são suficientes para que a LIO não fique inclinada. Conclusões: Outros fatores (por exemplo o ângulo de abertura do corpo ciliar, além da distância ao limbo na qual se transfixa a esclera, são importantes para o posicionamento das alças no sulco ciliar. Dois pontos de fixação são suficientes para que a LIO não apresente inclinação dentro do olho.Purpose: To assess, through ultrasound biomicroscopy (UBM, the positioning of the intraocular lenses (IOL haptics as related to the ciliary sulcus by using a scleral fixation technique; and to evaluate, as well, if two fixation points are sufficient to avoid tilting of the lenses.

    2007-07-01

    To evaluate safety and efficacy of additional palatal implants for snoring treatment. A prospective case series at two clinical sites in an office setting. Patients who did not have an acceptable reduction in snoring intensity after an initial 3 implant procedure received additional implants. Bed partners rated snoring intensity on a 10 cm visual analog scale (VAS) at baseline and 90 days postprocedure. Snoring intensity VAS decreased significantly from 6.4 +/- 2.3 to 4.6 +/- 2.9 (P < 0.01) for patients who received an additional fourth implant, and to 4.1 +/- 2.8 after the 5th implant (P<0.01). Epworth sleepiness scale scores also decreased significantly for patients who received additional fourth or fifth implants. There were no adverse events. Additional palatal implants for snoring treatment were safe and effective in this case series. Additional implants may offer relief for snorers not responding to the initial 3 implant procedure.

    Laser additive manufacturing offers a variety of new design possibilities. In mold making laser additive manufactured inserts with conformal cooling channels are already state of the art. Pneumatic ejectors for injection molds are a new application for laser additive manufacturing. The pneumatic ejectors require a durable gas permeable material. This material is produced by placing the scan vectors for the laser additive manufacturing process in a defined pattern. Trials with different plastics proofed the function and reliability of the pneumatic ejector concept in the injection molding cycle.

  3. ON IDENTIFICATION OF CONCRETE PLASTICIZING ADDITIVES

    Directory of Open Access Journals (Sweden)

    P. I. Yukhnevskiy

    2015-01-01

    Full Text Available Quality problem of chemical additives comes down in general to their objective and independent evaluation. As an identification is not made during product delivery for testing and while carrying out the testing there is difference in the results of investigations and finally construction products suffer from their poor quality. In this connection, it is proposed to make some alterations to revised version of the STB 1112 and GOST 30459, so that while supplying chemical additives for certification testing a certificate on additive quality should contain a standard of IR-spectra with active components. Simultaneously, the standard should be applied for additive testing results in accordance with rate efficiency criteria  for GOST 30459. Such norms are accepted for similar European standards.The paper presents a standard method for identification of organic additives according to IR-spectra, characteristic absorption bands for the Lignopan-type  additives and naphthalene formaldehyde super-plasticizer C-3. However, due to the fact that it is not possible to judge number of functional groups in the product by  absorption band size but it is possible only to assess their availability so it is recommended to use other methods. As an additional characteristics it is proposed to determine magnitude of the dipole moment in a  plasticizer-additive molecule. The authors previously developed a technique and  determined dipole moments in super-plasticizer-additives as in the form of powder so in the form of aqueous solutions, correlation relationship of water reduction additive capability with the magnitude of dipole moment. It has been proposed to manufacturers of plasticizing additives for concrete along with IR-spectra in the technical documentation to indicate a magnitude of the molecule dipole moment  as a generalized characteristics that determines its plasticizing properties.

  4. Additives in fuel oils - phase 2

    1997-06-01

    The project 'additives in fuel oils -phase 2' is a continuation of the prior study, which yielded in the Vaermeforsk report no 569 'Effects of using fuel oil additives in oil-fired burners'. As opposed to the first phase, which was a research study, the follow-up had more the dignity of testing a number of fuel oils with different additives in order to obtain results from combustion experiments under laboratory circumstances. The experiments were conducted in a 50 kW tube burner and the results from these trials can then be used as indications on how fuel oil additives can affect the emissions at large energy production plants. The conclusion of the project is that the additives could reduce the particle emissions for the low sulphureous oils by contribution to improved combustion of cenospherical particles and reducing the content of unburnt particles in the flue gases. The additives had no significant effect on the high sulphureous oils, which probably have different causes: The high content of asphaltenes yield particles, which are difficult to combust. Furthermore is the relatively high metal content in the oils an obstacle for the effect of the metal additives, since the adding of the catalyzing metals from the additives only marginally changes the total metal content of the composition. Any major differences between the different commercial additives could not be documented with the applied examination method. Despite that it could be verified that the catalytic additives had a better particle reducing effect than additives based on non-catalytic substance. General conclusions of the above mentioned results should only be drawn with large precaution. At the same time it should be said that the results gained with the experimental setup in this project can be looked upon and used as indications for expected results in commercial energy plants

    Full Text Available Food purchasing patterns have changed dramatically over the past fifty years. Packaged and processed foods get many a family through the day. They’re convenient, portable, and they stay fresh for a long time. There are over fourteen thousand man-made chemicals added to American food supply today. Food additives are not natural nutrition for humans or their pets. Children are suffering the most from food additives because they are exposed to food chemicals from infancy, and human bodies were not meant to be exposed to the degree of chemicals and food additives that we are currently. These additives, may include side effects, food allergies, increased waist lines, decreased absorption of minerals and vitamins, cancer and more. It is important for everyone to be aware of the types of chemicals and food additives they are consuming. [Archives Medical Review Journal 2010; 19(3.000: 141-154

    Coordinating additives are included in porphyrinoid-based materials to promote intermolecular organization and improve one or more photoelectric characteristics of the materials. The coordinating additives are selected from fullerene compounds and organic compounds having free electron pairs. Combinations of different coordinating additives can be used to tailor the characteristic properties of such porphyrinoid-based materials, including porphyrin oligomers. Bidentate ligands are one type of coordinating additive that can form coordination bonds with a central metal ion of two different porphyrinoid compounds to promote porphyrinoid alignment and/or pi-stacking. The coordinating additives can shift the absorption spectrum of a photoactive material toward higher wavelengths, increase the external quantum efficiency of the material, or both.

    The Additional Protocol between Japan and the IAEA entered into force in December 1999. To come into force a series of implementation trials of Additional Protocol was carried out at two Japanese representative nuclear research centers, i.e. Tokai Research Establishment of Japan Atomic Energy Research Institute (JAERI) and Oarai Engineering Center of Japan Nuclear Fuel Cycle Development Institute (JNC). These trials were proposed by Japan and were conducted in cooperation with the IAEA Secretariat. In addition, Japan amended 'the Law for the Regulation of Reactors etc.', to collect adequate information to submit to the IAEA, to arrange the surrounding for the complementary access, etc. In addition, Japan Submitted the Initial Declaration of the Additional Protocol within 180 days of the entry into force of the Protocol, in the middle of June, 2000

  16. Anaerobic sludge digestion with a biocatalytic additive

    Energy Technology Data Exchange (ETDEWEB)

    Ghosh, S.; Henry, M.P.; Fedde, P.A.

    1982-01-01

    The objective of this research was to evaluate the effects of a lactobacillus additive an anaerobic sludge digestion under normal, variable, and overload operating conditions. The additive was a whey fermentation product of an acid-tolerant strain of Lactobacillus acidophilus fortified with CaCO/sub 3/, (NH/sub 4/)/sub 2/HPO/sub 4/, ferrous lactate, and lactic acid. The lactobacillus additive is multifunctional in nature and provides growth factors, metabolic intermediates, and enzymes needed for substrate degradation and cellular synthesis. The experimental work consisted of several pairs of parallel mesophilic (35/sup 0/C) digestion runs (control and test) conducted in five experimental phases. Baseline runs without the additive showed that the two experimental digesters had the same methane content, gas production rate (GPR), and ethane yield. The effect of the additive was to increase methane yield and GPR by about 5% (which was statistically significant) during digester operation at a loading rate (LR) of 3.2 kg VS/m/sup 3/-day and a hydraulic retention time (HRT) of 14 days. Data collected from the various experimental phases showed that the biochemical additive increased methane yield, gas production rate, and VS reduction, and decreased volatile acids accumulation. In addition, it enhanced digester buffer capacity and improved the fertilizer value and dewatering characteristics of the digested residue.

  17. The grays of medical device color additives.

    2014-01-01

    The United States' medical device color additive regulations are unknown to some, and confusing to many. This article reviews statutory language on color additives in the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended, including the Delaney Clause on carcinogenicity; color additive regulatory language as it relates to medical devices in Title 21 of the Code of Federal Regulations (C.F.R.), Parts 70-82; reports on the Food and Drug Administration's (FDA's) likely current and historical practices in dealing with color additives in medical devices; and speculates on what may have given rise to decades of seemingly ad hoc color additives practices, which may now be difficult to reconstruct and satisfactorily modify. Also addressed is the Center for Devices and Radiological Health's (CDRH's) recent publicly-vetted approach to color additives in Section 7 of its April 2013 draft guidance, Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," which the author concludes is a change in the right direction, but which, at least in its current draft form, is not a fix to the CDRH's color additives dilemma. Lastly, the article suggests what the CDRH might consider in further developing a new approach to color additives. Such an approach would treat color additives as if they were any other potentially toxic group of chemicals, and could be fashioned in such a way that the CDRH could still satisfy the broad aspects of Congressional color additives mandates, and.yet be consistent with ISO 10993. In doing this, the CDRH would need to recommend a more directed use of its Quality System Regulation, 21 C.F.R. Part 820, for material and vendor qualification and validation in general; approach Congress for needed statutory changes; or make administrative changes. In order for any approach to be successful, whether it is a new twist on past practices, or an entirely new path forward, the FDA must, to the best of its

    2016-01-01

    Full Text Available The article deals with the issues concerning the formation of the structure and properties of fine-grained concrete with organomineral additive produced through mechanochemical activation of thermal power plant fly ash together with superplasticizer. The additive is produced in a high-speed activator at the collision particles’ speed of about 80 m/s. The use of the additive in fine-grained concrete in the amounts of 0.5-1% increased the strength by 30-50% and reduced the size and volume of pores. The cement consumption in such concrete is close to the cement consumption in common concrete of equal resistance.

  19. Graphite and Hybrid Nanomaterials as Lubricant Additives

    Directory of Open Access Journals (Sweden)

    Zhenyu J. Zhang

    2014-04-01

    Full Text Available Lubricant additives, based on inorganic nanoparticles coated with organic outer layer, can reduce wear and increase load-carrying capacity of base oil remarkably, indicating the great potential of hybrid nanoparticles as anti-wear and extreme-pressure additives with excellent levels of performance. The organic part in the hybrid materials improves their flexibility and stability, while the inorganic part is responsible for hardness. The relationship between the design parameters of the organic coatings, such as molecular architecture and the lubrication performance, however, remains to be fully elucidated. A survey of current understanding of hybrid nanoparticles as lubricant additives is presented in this review.

    Denneberg, Dieter

    1994-01-01

    Non-Additive Measure and Integral is the first systematic approach to the subject. Much of the additive theory (convergence theorems, Lebesgue spaces, representation theorems) is generalized, at least for submodular measures which are characterized by having a subadditive integral. The theory is of interest for applications to economic decision theory (decisions under risk and uncertainty), to statistics (including belief functions, fuzzy measures) to cooperative game theory, artificial intelligence, insurance, etc. Non-Additive Measure and Integral collects the results of scattered and often isolated approaches to non-additive measures and their integrals which originate in pure mathematics, potential theory, statistics, game theory, economic decision theory and other fields of application. It unifies, simplifies and generalizes known results and supplements the theory with new results, thus providing a sound basis for applications and further research in this growing field of increasing interest. It also co...

    1996-01-01

    Full text: Detailed studies on the accelerative effect of novel additives in radiation grafting and curing using acrylated monomer/oligomer systems have been performed in the presence of ionising radiation and UV as sources. Methyl methacrylate (MMA) is used as typical monomer for these grafting studies in the presence of the additives with model backbone polymers, cellulose and propropylene. Additives which have been found to accelerate these grafting processes are: mineral acid, occlusion compounds like urea, thermal initiators and photoinitiators as well as multifunctional monomers such as multifunctional acrylates. The results from irradiation with gamma rays have also been compared with irradiation from a 90W UV lamp. The role of the above additives in accelerating the analogous process of radiation curing has been investigated. Acrylated urethanes, epoxies and polyesters are used as oligomers together with acrylated monomers in this work with uv lamps of 300 watts/inch as radiation source. In the UV curing process bonding between film and substrate is usually due to physical forces. In the present work the presence of additives are shown to influence the occurrence of concurrent grafting during cure thus affecting the nature of the bonding of the cured film. The conditions under which concurrent grafting with UV can occur will be examined. A mechanism for accelerative effect of these additives in both grafting and curing processes has been proposed involving radiation effects and partitioning phenomena

    Allcorn, Eric [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

    2017-10-13

    Lithium-ion battery safety is a critical issue in the adoption of the chemistry to larger scale applications such as transportation and stationary storage. One of the critical components impacting the safety of lithium-ion batteries is their use of highly flammable organic electrolytes. In this work, brominated flame retardants (BFR’s) – an existing class of flame retardant materials – are incorporated as additives to lithium-ion battery electrolytes with the intention to reduce the electrolyte flammability and thereby improve safety. There are a few critical needs for a successful electrolyte additive: solubility in the electrolyte, electrochemical stability over the range of battery operation, and minimal detrimental effects on battery performance. Those detrimental effects can take the form of electrolyte specific impacts, such as a reduction in conductivity, or electrode impacts, such as SEI-layer modification or chemical instability to the active material. In addition to these needs, the electrolyte additive also needs to achieve its intended purpose, which in this case is to reduce the flammability of the electrolyte. For the work conducted as part of this SPP agreement three separate BFR materials were provided by Albemarle to be tested by Sandia as additives in a traditional lithium-ion battery electrolyte. The provided BFR materials were tribromo-neopentyl alcohol, tetrabromo bisphenol A, and tribromoethylene. These materials were incorporated as separate 4 wt.% additives into a traditional lithium-ion battery electrolyte and compared to said traditional electrolyte, designated Gen2.

  16. The challenges of additional protocol implementation

    2001-01-01

    Full text: The IAEA Board of Governors approved the Model Protocol Additional to Safeguards Agreements, INFCIRC/540, (referred to as the Additional Protocol) in May 1997. The Additional Protocol provides for new mechanisms that include expanded information on State's nuclear activities to be declared to the IAEA and increased physical access to locations for IAEA inspectors. The objective is to provide the basis for gaining assurance of the absence of undeclared nuclear material and activities in a State. Although the Agency conducted field trials of various aspects of implementation of the Additional Protocol, the first actual implementation experience began with the entry into force of Australia's additional protocol in December of 1997. As of late August 2001,21 states have entered into force an additional protocol and another 35 states have signed the additional protocol but not yet entered the agreement into force. Because implementation of the Additional Protocol requires new activities to be carried out by the IAEA, new procedures, guidelines and training have been developed to support these activities. As more experience is gained these documents are being refined and additional ones developed to meet unforeseen needs. In addition, evaluation and follow-up of the expanded information and the results of increased access has required the Safeguards Department to expand and adapt its procedures and mode of operation. The challenge has been in establishing sufficient measures and the necessary infrastructure for consistent application of the additional protocol in such a way that they can be adapted as needed based on Agency experience. Initial development focused on the logistical aspects of implementing these new activities. These activities include the processing, handling and review of additional protocol declarations; planning, conducting and reporting on complementary access activities; and follow-up activities arising from information review or

    Ahuja, Bhrigu; Karg, Michael; Schmidt, Michael

    2015-03-01

    Additive manufacturing, characterized by its inherent layer by layer fabrication methodology has been coined by many as the latest revolution in the manufacturing industry. Due to its diversification of Materials, processes, system technology and applications, Additive Manufacturing has been synonymized with terminology such as Rapid prototyping, 3D printing, free-form fabrication, Additive Layer Manufacturing, etc. A huge media and public interest in the technology has led to an innovative attempt of exploring the technology for applications beyond the scope of the traditional engineering industry. Nevertheless, it is believed that a critical factor for the long-term success of Additive Manufacturing would be its ability to fulfill the requirements defined by the traditional manufacturing industry. A parallel development in market trends and product requirements has also lead to a wider scope of opportunities for Additive Manufacturing. The presented paper discusses some of the key challenges which are critical to ensure that Additive Manufacturing is truly accepted as a mainstream production technology in the industry. These challenges would highlight on various aspects of production such as product requirements, process management, data management, intellectual property, work flow management, quality assurance, resource planning, etc. In Addition, changing market trends such as product life cycle, mass customization, sustainability, environmental impact and localized production will form the foundation for the follow up discussion on the current limitations and the corresponding research opportunities. A discussion on ongoing research to address these challenges would include topics like process monitoring, design complexity, process standardization, multi-material and hybrid fabrication, new material development, etc.

    2002-01-01

    Background and purpose: To assess the correlation between different general and organ specific quality of life and morbidity scoring methods in a cohort of men treated with radical radiotherapy for prostate cancer. Materials and methods: Men who had been treated with radical radiotherapy (50 Gy in 16 fractions over 21 days) for localized prostate cancer more than 3 years previously and who had no evidence of recurrent disease were invited to take part in the study. A total of 101 of 135 invited patients agreed and completed LENT/SOMA, UCLA Prostate Cancer Index, and 36 item RAND Health survey questionnaires. Results: The patients had comparable results with other published series with respect to the UCLA and SF-36 indices. There was significant correlation between the corresponding parts of the UCLA and LENT/SOMA scales (P<0.0005). However, for the same symptoms, a patient tended to score lower (worse) on the UCLA scale in comparison to LENT/SOMA. The relationship between the average LENT/SOMA score and maximum score was also not straightforward with each set of data revealing different information. Conclusions: The LENT/SOMA questions were, in the main, more wide-ranging and informative than the UCLA index. It is helpful to give both the overall and maximum LENT/SOMA scores to most efficiently use all of the data. There may need to be a further LENT/SOMA question to allow both symptoms of tenesmus and faecal urgency to be fully addressed

    Contrary to common believing, the prevalence of the intolerance to food additives in the general population is rather low. Nowadays many doubts persist with regard both to the pathogenetic mechanisms and to the clinical and diagnostic aspects in this field. Symptoms due to, or exacerbated from, food additives usually involve non-IgE-mediate mechanisms (pseudo-allergic reactions, PAR) and are usually less severe of those induced by food allergy. The most frequent clinical feature of the intolerance to food additives still remains the urticaria-angioedema syndrome, although these substances are really involved only in a minority of patients. Other possible clinical features include anaphylaxis, atopic eczema, behaviour disturbances, asthma and non-allergic rhinitis. The diagnostic approach consists in diary cards, reporting symptoms and food habits, elimination diet and double blinded placebo-controlled oral challenge with suspected additives. However, such procedure still remains poorly standardized and numerous uncertainties persist with regard to optimal conditions for performing and interpret the challenge results. The therapeutic approach consists in the exclusion of foods and products containing the additive involved, and, in patients not compliant to the diet, in treatment with symptomatic drugs.

    This paper shows a numerical evaluation of fuels and additives for HCCl combustion. First, a long list of candidate HCCl fuels is selected. For all the fuels in the list, operating conditions (compression ratio, equivalence ratio and intake temperature) are determined that result in optimum performance under typical operation for a heavy-duty engine. Fuels are also characterized by presenting Log(p)-Log(T) maps for multiple fuels under HCCl conditions. Log(p)-Log(T) maps illustrate important processes during HCCl engine operation, including compression, low temperature heat release and ignition. Log(p)-Log(T) diagrams can be used for visualizing these processes and can be used as a tool for detailed analysis of HCCl combustion. The paper also includes a ranking of many potential additives. Experiments and analyses have indicated that small amounts (a few parts per million) of secondary fuels (additives) may considerably affect HCCl combustion and may play a significant role in controlling HCCl combustion. Additives are ranked according to their capability to advance HCCl ignition. The best additives are listed and an explanation of their effect on HCCl combustion is included

    Full Text Available The main goal of this paper is excessive additive (for oil filling effect on engine oil dynamic viscosity. Research is focused to commercially distribute automotive engine oil with viscosity class 15W–40 designed for vans. There were prepared blends of new and used engine oil without and with oil additive in specific ratio according manufacturer’s recommendations. Dynamic viscosity of blends with additive was compared with pure new and pure used engine oil. The temperature dependence dynamic viscosity of samples was evaluated by using rotary viscometer with standard spindle. Concern was that the oil additive can moves engine oil of several viscosity grades up. It is able to lead to failure in the engine. Mathematical models were used for fitting experimental values of dynamic viscosity. Exponential fit function was selected, which was very accurate because the coefficient of determination R2 achieved high values (0.98–0.99. These models are able to predict viscosity behaviour blends of engine oil and additive.

    Laser-based additive manufacturing has attracted much attention as a promising 3D printing method for metallic components in recent years. However, surface roughness of additive manufactured components has been considered as a challenge to achieve high performance. In this work, we demonstrate the capability of fiber laser in polishing rough surface of additive manufactured Ti-based alloys as Ti-6Al-4V and TC11. Both as-received surface and laser-polished surfaces as well as cross-section subsurfaces were analyzed carefully by White-Light Interference, Confocal Microscope, Focus Ion Beam, Scanning Electron Microscopy, Energy Dispersive Spectrometer, and X-ray Diffraction. Results revealed that as-received Ti-based alloys with surface roughness more than 5 μm could be reduce to less than 1 μm through laser polishing process. Moreover, microstructure, microhardness and wear resistance of laser-polished zone was investigated in order to examine the thermal effect of laser polishing processing on the substrate of additive manufactured Ti alloys. This proof-of-concept process has the potential to effectively improve the surface roughness of additive manufactured metallic alloy by local polishing method without damage to the substrate.

  3. Effects from additives on deacetylation of chitin

    International Nuclear Information System (INIS)

    Campana Filho, Sergio P.; Signini, Roberta

    2001-01-01

    Deacetylation reactions of commercial chitin were carried out in aqueous sodium hydroxide solution at 115 deg C for 6 hours. The effect from additives (sodium borohydride or anthraquinone) and of bubbling inert gas (nitrogen or argon) on the characteristics of deacetylated samples were evaluated. Average degrees of acetylation and intrinsic viscosity were determined by 1 H NMR spectroscopy and capillary viscometry, respectively. X-ray diffraction was employed to evaluate changes in crystallinity and infrared spectroscopy was used to monitor structural changes due to deacetylation. The bubbling of inert gas during the deacetylation reaction resulted in more crystalline samples of chitosan. Deacetylation carried out without any additive produced slightly more deacetylated chitosan but they were severely depolymerized. The depolymerization process was much less important when sodium borohydride was added to the reaction medium but the addition of anthraquinone and the bubbling of nitrogen, or argon, did not have any effect, this suggests that oxygen is not required for depolymerization.

The PPG-ORNL study successfully demonstrated that polymeric coatings formulations may overcome many limitations of common thermoplastics used in additive manufacturing (AM), allow lightweight nozzle design for material deposition and increase build rate. The materials effort focused on layer-by-layer deposition of coatings with each layer fusing together. The combination of materials and deposition results in an additively manufactured build that has sufficient mechanical properties to bear the load of additional layers, yet is capable of bonding across the z-layers to improve build direction strength. The formulation properties were tuned to enable a novel, high-throughput deposition method that is highly scalable, compatible with high loading of reinforcing fillers, and is inherently low-cost.

  5. Adverse reactions to the sulphite additives

    Misso, Neil LA

    2012-01-01

    Sulphites are widely used as preservative and antioxidant additives in the food and pharmaceutical industries. Exposure to sulphites has been reported to induce a range of adverse clinical effects in sensitive individuals, ranging from dermatitis, urticaria, flushing, hypotension, abdominal pain and diarrhoea to life-threatening anaphylactic and asthmatic reactions. Exposure to the sulphites arises mainly from the consumption of foods and drinks that contain these additives; however exposure may also occur through the use of pharmaceutical products, as well as in occupational settings. Most studies report a prevalence of sulphite sensitivity of 3 to 10% among asthmatic subjects who ingest these additives. However, the severity of these reactions varies, and steroid-dependent asthmatics, those with marked airway hyperresponsiveness, and children with chronic asthma, appear to be at greater risk. Although a number of potential mechanisms have been proposed, the precise mechanisms underlying sulphite sensitivity remain unclear. PMID:24834193

    2015-01-01

    The Additive Construction with Mobile Emplacement (ACME) project is developing technology to build structures on planetary surfaces using in-situ resources. The project focuses on the construction of both 2D (landing pads, roads, and structure foundations) and 3D (habitats, garages, radiation shelters, and other structures) infrastructure needs for planetary surface missions. The ACME project seeks to raise the Technology Readiness Level (TRL) of two components needed for planetary surface habitation and exploration: 3D additive construction (e.g., contour crafting), and excavation and handling technologies (to effectively and continuously produce in-situ feedstock). Additionally, the ACME project supports the research and development of new materials for planetary surface construction, with the goal of reducing the amount of material to be launched from Earth.

  9. Transfer of Training in Simple Addition.

    Science.gov (United States)

    Chen, Yalin; Campbell, Jamie I D

    2017-04-18

    In recent years several researchers have proposed that skilled adults may solve single-digit addition problems (e.g. 3 + 1 = 4, 4 + 3 = 7) using a fast counting procedure. Practicing a procedure, often leads to transfer of learning and faster performance of unpracticed items. Such transfer has been demonstrated using a counting-based alphabet arithmetic task (e.g., B + 4 = C D E F) that indicated robust generalization of practice (i.e., RT gains) when untrained transfer problems at test had been implicitly practiced (e.g., practice B + 3, test B + 2 or B + 1). Here we constructed analogous simple addition problems (practice 4 + 3, test 4 + 2 or 4 + 1). In each of three experiments (total n = 108) participants received six practice blocks followed by two test blocks of new problems to examine generalization effects. Practice of addition identity-rule problems (i.e., 0 + N = N) showed complete transfer of RT gains made during practice to unpracticed items at test. In contrast, the addition ties (2 + 2, 3 + 3, etc.) presented large RT costs for unpracticed problems at test, but sped up substantially in the second test block. This pattern is consistent with item-specific strengthening of associative memory. The critical items were small non-tie additions (sum ≤ 10) for which the test problems would be implicitly practiced if counting was employed during practice. In all three experiments (and collectively) there was no evidence of generalization for these items in the first test block, but there was robust speed up when the items were repeated in the second test block. Thus, there was no evidence of the generalization of practice that would be expected if counting procedures mediated our participants' performance on small non-tie addition problems.

  10. Electronic stopping in oxides beyond Bragg additivity

    Sigmund, P.; Schinner, A.

    2018-01-01

    We present stopping cross sections calculated by our PASS code for several ions in metal oxides and SiO2 over a wide energy range. Input takes into account changes in the valence structure by assigning two additional electrons to the 2p shell of oxygen and removing the appropriate number of electrons from the outer shells of the metal atom. Results are compared with tabulated experimental values and with two versions of Bragg's additivity rule. Calculated stopping cross sections are applied in testing a recently-proposed scaling rule, which relates the stopping cross section to the number of oxygen atoms per molecule.

  11. Studies of alumina additions in zirconia - magnesia

    International Nuclear Information System (INIS)

    Muccillo, R.

    1987-01-01

    Ionic conductivity measurements have been carried out in the 500 0 C - 1000 0 C temperature range in Mg - PSZ (Partially Stabilized Zirconia) with 0.5 to 10 mol % alumina additions. All specimens were prepared by pressing followed by pre - and sintering at 1000 0 C/2h and1450 0 C/4h, respectively. Thermal histerysis of the ionic conductivity have been detected, probably due to phase changes in the Mg-PSZ samples. The results show that alumina additions up to 2.1% enhances densification with no major variations in electrical resistivity values. (Author) [pt

    Additive manufacturing techniques may be utilized to construct effusion plates. Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.

    Additive Manufacturing (AM) enables the creation of complex structures directly from a computer-aided design (CAD). There are limitations that prevent the technology from realizing its full potential. AM has been criticized for being slow and expensive with limited build size. Oak Ridge National Laboratory (ORNL) has developed a large scale AM system that improves upon each of these areas by more than an order of magnitude. The Big Area Additive Manufacturing (BAAM) system directly converts low cost pellets into a large, three-dimensional part at a rate exceeding 25 kg/h. By breaking these traditional barriers, it is possible for polymer AM to penetrate new manufacturing markets.

    2017-12-01

    The article concerns the idea of using selected mineral additives in the pavement quality concrete composition. The basis of the research paper was the modification of cement concrete intended for airfield pavements. The application of the additives: metakaolonite and natural zeolite was suggested. Analyses included the assessment of basic physical properties of modifiers. Screening analysis, assessment of micro structure and chemical microanalysis were conducted in case of these materials. The influence of the applied additives on the change of concrete mix parameters was also presented. The impact of zeolite and metakaolinite on the mix density, oxygen content and consistency class was analysed. The influence of modifiers on physical and mechanical changes of the hardened cement concrete was discussed (concrete density, compressive strength and bending strength during fracturing) in diversified research periods. The impact of the applied additives on the changes of internal structure of cement concrete was discussed. Observation of concrete micro structure was conducted using the scanning electron microscope. According to the obtained lab test results, parameters of the applied modifiers and their influence on changes of internal structure of cement concrete are reflected in the increase of mechanical properties of pavement quality concrete. The increase of compressive and bending strength in case of all analysed research periods was proved.

    Kostić Miloje M.

    2011-01-01

    Full Text Available The proposed procedure is based on the fact that total transformer losses (PLL1,n, determined by short circuit test, can be separated into two components: the eddy current losses in the windings (PEC1,n and stray flux losses (PSL1,n in iron parts of construction as well as in the transformer tank walls. The total additional load losses, PLLd1 and PLLdh, are determined by short circuit test results, conducted at rated frequency (f1 and at increased harmonic frequency (fh=h*f1. Using so obtained total additional load losses, PLLd1 and PLLdh, which can be expressed in the form PLLdh=PEC1,n*h2 + PSL1,n*h, the corresponding rate additional load losses values PEC1,n and PSL1,n are derived. At the end, for given load with predefined high harmonics content, (Ih/I1n, relative to rated current, the total additional load losses value ΣPLLdh > PLLd1, is found. In such a way all harmonics up to hmax are taken into account.

    2001-01-01

    Information for mine planning requires to be close spaced, if compared to the grid used for exploration and resource assessment. The additional samples collected during quasimining usually are located in the same pattern of the original diamond drillholes net but closer spaced. This procedure is not the best in mathematical sense for selecting a location. The impact of an additional information to reduce the uncertainty about the parameter been modeled is not the same everywhere within the deposit. Some locations are more sensitive in reducing the local and global uncertainty than others. This study introduces a methodology to select additional sample locations based on stochastic simulation. The procedure takes into account data variability and their spatial location. Multiple equally probable models representing a geological attribute are generated via geostatistical simulation. These models share basically the same histogram and the same variogram obtained from the original data set. At each block belonging to the model a value is obtained from the n simulations and their combination allows one to access local variability. Variability is measured using an uncertainty index proposed. This index was used to map zones of high variability. A value extracted from a given simulation is added to the original data set from a zone identified as erratic in the previous maps. The process of adding samples and simulation is repeated and the benefit of the additional sample is evaluated. The benefit in terms of uncertainty reduction is measure locally and globally. The procedure showed to be robust and theoretically sound, mapping zones where the additional information is most beneficial. A case study in a coal mine using coal seam thickness illustrates the method

    study was performed, including 66 patients who underwent colonic resections due to cancer, for 58 months at Hospital Universitario of Universidade de São Paulo. These patients were divided in two groups, group 1, submitted to elective surgery (28 patients, and group 2, submitted to emergency surgery (38 patients. The groups were comparable for gender, age, clinical presentation, surgical procedure techniques, tumor distribution, TNM stage, morbidity, postoperative hospital stay and postoperative mortality. No difference was observed in patients’age. Males were predominant in the urgency surgery group. Lower gastrointestinal bleeding was the main symptom in the elective group, whereas abdominal pain was the main symptom in the urgency group. Mostly of the patients were having symptoms for months at the time of surgery. Urgency group patients presented more pT4 tumors, and elective group patients presented more stage I cancer. In both groups the oncologic approach was achieved, as well as primary anastomosis rates (81.8%. No differences in average hospital stay, hospital morbidity or postoperative mortality were recorded.

    Given a von Neumann algebra M we introduce the so-called central extension mix(M) of M. We show that mix(M) is a *-subalgebra in the algebra LS(M) of all locally measurable operators with respect to M, and this algebra coincides with LS(M) if and only if M does not admit type II direct summands. We prove that if M is a properly infinite von Neumann algebra then every additive derivation on the algebra mix(M) is inner. This implies that on the algebra LS(M), where M is a type I ∞ or a type III von Neumann algebra, all additive derivations are inner derivations. (author)

    The machinability of the plain carbon and low alloy structural steels with carbon content of 0.1-0.6% is briefly discussed in the first part of the paper. In the experimental part a dependence between the addition of calcium and some changes in sulphide and oxide inclusions morphology is presented. The Volvo test for measurement of machinability index B i has been applied. Using the multiple regression methods two relationships between machinability index B i and stereological parameters of non-metallic inclusions as well as hardness of the steels have been calculated. The authors have reached the conclusion that owing to the changes in inclusion chemical composition and geometry as result of calcium addition the machinability index of the steel can be higher.

    The extremely high melting point of many ceramics adds challenges to additive manufacturing as compared with metals and polymers. Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. These polymer structures can be pyrolyzed to a ceramic with uniform shrinkage and virtually no porosity. Silicon oxycarbide microlattice and honeycomb cellular materials fabricated with this approach exhibit higher strength than ceramic foams of similar density. Additive manufacturing of such materials is of interest for propulsion components, thermal protection systems, porous burners, microelectromechanical systems, and electronic device packaging.

  18. Multi-canister overpack: additional NRC requirements

    The U.S. Department of Energy (DOE) established in the K Basin Spent Fuel Project, Regulatory Policy, dated August 4, 1995 (hereafter referred to as the Policy), the requirement for new Spent Nuclear Fuel Project (SNFP) facilities to achieve ''nuclear safety equivalency'' to comparable U.S. Nuclear Regulatory Commission licensed facilities. For activities other than during transport, when the Multi-Canister Overpack (MCO) is used and resides in the Canister Storage Building (CSB), Conditioning Facility or K Basins Path Forward Projects, additional NRC requirements will also apply to the MCO based on the safety functions it performs and its interfaces with the SNFP facilities. An evaluation was performed in consideration of the MCO safety functions to identify any additional NRC requirements, to establish nuclear safety equivalency for the MCO

    Microbial biosurfactants with high ability to reduce surface and interfacial surface tension and conferring important properties such as emulsification, detergency, solubilization, lubrication and phase dispersion have a wide range of potential applications in many industries. Significant interest in these compounds has been demonstrated by environmental, bioremediation, oil, petroleum, food, beverage, cosmetic and pharmaceutical industries attracted by their low toxicity, biodegradability and sustainable production technologies. Despite having significant potentials associated with emulsion formation, stabilization, antiadhesive and antimicrobial activities, significantly less output and applications have been reported in food industry. This has been exacerbated by uneconomical or uncompetitive costing issues for their production when compared to plant or chemical counterparts. In this review, biosurfactants properties, present uses and potential future applications as food additives acting as thickening, emulsifying, dispersing or stabilising agents in addition to the use of sustainable economic processes utilising agro-industrial wastes as alternative substrates for their production are discussed. © 2013 American Institute of Chemical Engineers.

    The frequent media reports on food additives weakened consumers' trust in food producers and food control authorities as well. Furthermore, consumers' uncertainty is also raised by the fact that they obtain their information from inadequate, mistrustful sources and, therefore, consumers might avoid the consumption of certain foodstuffs. While food producers may react by replacing artificial components by natural ones, they try to emphasize the favourable characteristics of their products. The authors describe the main trends and efforts related to food additives. On the basis of the overview it can be concluded that - besides taking into consideration consumers' needs - product development and research directions are promising. Food producers' efforts may help to restore consumer confidence and trust and they may help them to have informed choice.
