Net impact of remediation
Authors: Gibbs James , Santillan Javier , Horin Jon 
Published: September 2009

AbstractFollowing years of progress in designing and executing cleanups of contaminants at waste sites, the U.S. Air Force, state regulatory groups, and others are crafting methods to evaluate broader considerations of risk in remedial decisions. Integrating worker and climate risks into remediation efforts may confer significant benefits, but challenges exist to identifying, assessing, and accounting for them in the remedial process.For sites where future risk posed by contamination far exceeds the risk posed to workers who may be exposed to the contaminants during the remedial process, limiting the range of decision inputs to those presented by the site conditions made sense and provided a net benefit to human health and the environment. There are other sites, however, where future risk posed by the in situ contamination are at levels comparable to the real risks posed to workers, ecology, and even emerging concerns about climate change. For these sites, a net risk reduction cannot be assumed to be a result of remedial action, challenging the remedial community to develop new approaches to ensure positive results. © 2009 Wiley Periodicals, Inc.
Maternal psychological well‐being and salivary cortisol in late pregnancy and early post‐partum
Authors: Cheng Ching‐Yu , Pickler Rita H. 
Published: September 2009

AbstractMaternal cortisol plays an important role in foetal development and is often used to measure stress. In addition to stress, prenatal and post‐partum women experience a mix of positive and negative emotions. However, few studies have examined the relationship between cortisol and maternal psychological health or how these relationships change from the prenatal to the post‐partum periods. The purpose of this study was to examine the relationships between maternal cortisol and stress, happiness, and depression components of psychological well‐being, in late pregnancy and early post‐partum. The study used a repeated measure design with 41 women; 21 women completed all data collections. As expected, maternal salivary cortisol increased from awakening to 30 minutes after awakening during pregnancy. Levels of salivary cortisol were lower at post‐partum. Stress, happiness and depression were significantly correlated at both prenatal and post‐partum measurements. Prenatal cortisol awakening response was correlated with happiness. Maternal psychological well‐being and cortisol did not differ by parity, race or employment. Maternal cortisol could potentially serve as a biochemical marker of maternal psychological well‐being. Interventions to decrease maternal stress may promote maternal psychological well‐being. Longitudinal studies with larger sample and diverse ethnicities may increase our understanding of the role of cortisol in foetal and maternal health. Copyright © 2009 John Wiley & Sons, Ltd.
Early Reoperation After Laparoscopic Fundoplication: The Importance of Routine Postoperative Contrast Studies
Authors: Tsunoda Shigeru , Jamieson Glyn G. , Devitt Peter G. , Watson David I. , Thompson Sarah K. 
Published: September 2009

AbstractBackgroundThe necessity for routine postoperative contrast studies following laparoscopic fundoplication for either gastroesophageal reflux disease or paraesophageal hernia is unclear.MethodsTo determine whether a routine contrast X‐ray film influenced surgical decision making following laparoscopic fundoplication, we reviewed records from a prospective database of 1,894 patients who underwent a primary laparoscopic fundoplication for gastroesophageal reflux disease or paraesophageal hernia between October 1991 and June 2008, and identified those who underwent early reoperation. The value of early routine postoperative barium swallow examinations in the management of these patients was then determined.ResultsThe review showed that 53 patients (2.8%) underwent reoperative procedures within seven days of their original operation: 21 had originally undergone surgery for a paraesophageal hernia, and 32 for reflux. Of the 53 patients who underwent reoperaiton, 25 (47.2%) were treated for dysphagia, 17 (32.1%) for acute paraesophageal hernia, 6 (11.3%) for a gastrointestinal leak, and 5 (9.4%) for bleeding or peritonitis. Fifteen of the 17 patients who underwent repair of an acute hiatus hernia (0.8% of all patients) had no symptoms and underwent reoperative surgery because of radiological findings alone. Primary surgery for a large hiatus hernia was associated with a higher incidence of early reoperation (5.2 vs. 2.2%; P = 0.001).ConclusionsApproximately 1 in 125 patients who underwent laparoscopic surgery for reflux or a large hiatus hernia had an important finding on an early postoperative contrast swallow, and benefited from this investigation by undergoing early reoperative intervention.
Variable phenotypic expression of a MECP2 mutation in a family
Authors: Augenstein Kimberly , Lane Jane B. , Horton Antony , Schanen Carolyn , Percy Alan K. 
Published: September 2009

Abstract
We report a three generation family in which five members, three females and two males, demonstrate a 44 bp deletion (1164–1207del44) in the MECP2 gene associated with Rett syndrome, leading to a truncation of the C-terminus of the protein. Two of the three females and both males do not meet RTT criteria whereas the youngest female has classic RTT. Both males demonstrated a clear pattern of progressive involvement including dystonia. The transmitting females do not demonstrate features of RTT as a result of unbalanced X chromosome inactivation (XCI) and were only identified as carriers following the evaluation of the affected males and the girl with classic RTT. As such, accurate assessment of the precise frequency of MECP2 mutations in carrier females with mild cognitive impairment or borderline cognitive function will be under-represented unless an affected offspring is recognized. Strategies for accurate diagnosis in such instances should be considered carefully.
On plate decompositions of cone multipliers
Authors: Garrigós Gustavo , Seeger Andreas 
Published: September 2009

AbstractAn important inequality due to Wolff on plate decompositions of cone multipliers is known to have consequences for sharp Lp results on cone multipliers, local smoothing for the wave equation, convolutions with radial kernels, Bergman projections in tubes over cones, averages over finite-type curves in ℝ3 and associated maximal functions. We observe that the range of p in Wolff's inequality, for the conic and the spherical versions, can be improved by using bilinear restriction results. We also use this inequality to give some improved estimates on square functions associated to decompositions of cone multipliers in low dimensions. This gives a new L4 bound for the cone multiplier operator in ℝ3.
Inner functions in the Möbius invariant Besov-type spaces
Authors: Pérez-González Fernando , Rättyä Jouni 
Published: September 2009

AbstractAn analytic function f in the unit disc $\mathbb{D}$ belongs to F(p,q,s), ifis uniformly bounded for all a ∈ $\mathbb{D}$. Here $g(z,a)=-\log|\varphi_a(z)|$ is the Green function of $\mathbb{D}$, and φa(z)=(a−z)/(1−āz). It is shown that for 0 < γ < ∞ and |w|=1 the singular inner function exp(γ(z+w)/(z−w)) belongs to F(p,q,s), 0<s≤1, if and only if $p\le q+\tfrac12(s+3)$. Moreover, it is proved that, if 0<s<1, then an inner function belongs to the Möbius invariant Besov-type space $B^p_s=F(p,p-2,s)$ for some (equivalently for all) p > max{s,1−s} if and only if it is a Blaschke product whose zero sequence {zn} satisfies $\smash{\sup_{a\in\mathbb{D}}\sum_{n=1}^\infty(1-|\varphi_{a}(z_n)|^2)^s<\infty}$.
On the existence of positive solutions on the half-line to nonlinear two-dimensional delay differential systems
Authors: Philos Ch. G. 
Published: September 2009

AbstractThis paper is concerned with a boundary-value problem on the half-line for nonlinear two-dimensional delay differential systems with positive delays. A theorem is established, which provides sufficient conditions for the existence of positive solutions. The application of this theorem to the special case of second-order nonlinear delay differential equations is given. Also, the application of the theorem to two-dimensional Emden–Fowler-type delay differential systems with constant delays is presented. Moreover, some general examples demonstrating the applicability of the theorem are included.
Combinatorial Gelfand models for some semigroups and q-rook monoid algebras
Authors: Kudryavtseva Ganna , Mazorchuk Volodymyr 
Published: September 2009

AbstractInspired by the results of Adin, Postnikov and Roichman, we propose combinatorial Gelfand models for semigroup algebras of some finite semigroups, which include the symmetric inverse semigroup, the dual symmetric inverse semigroup, the maximal factorizable subsemigroup in the dual symmetric inverse semigroup and the factor power of the symmetric group. Furthermore, we extend the Gelfand model for the semigroup algebras of the symmetric inverse semigroup to a Gelfand model for the q-rook monoid algebra.
Discrete Tracy–Widom operators
Authors: Blower Gordon , McCafferty Andrew 
Published: September 2009

AbstractIntegrable operators arise in random matrix theory, where they describe the asymptotic eigenvalue distribution of large self-adjoint random matrices from the generalized unitary ensembles. We consider discrete Tracy–Widom operators and give sufficient conditions for a discrete integrable operator to be the square of a Hankel matrix. Examples include the discrete Bessel kernel and kernels arising from the almost Mathieu equation and the Fourier transform of Mathieu's equation.
The taxonomy of theCaloplaca citrinagroup (Teloschistaceae) in the Black Sea region; with contributions to the cryptic species concept in lichenology
Authors: VONDRÁK Jan , ŘÍHA Pavel , ARUP Ulf , SØCHTING Ulrik 
Published: September 2009

AbstractA new taxonomy of theCaloplaca citrinagroup in the Black Sea region is presented. It is based on the nrDNA ITS molecular data, chemistry (anthraquinone contents) and 20 morphological characters. Six species previously known in the region are accepted:Caloplaca arcis,C. calcitrapa,C. dichroa,C. flavocitrina,C. geleverjae,C. limonia. Five new species are described:Caloplaca arcisproxima,C. austrocitrina,C. communis,C. confusaandC. nigromarina. Seven further species,Caloplaca britannica,C. citrina,C. marina,C. maritima,C. microthallina,C. oraandC. phloginaare also treated briefly. Some maritime species known from the Atlantic coast of Europe are absent from the region, and, surprisingly,Caloplaca citrinas. str. could not be confirmed from the study area. A key to the species present in the region is provided, although morphological characters are of very limited value in this group. The variability and taxonomic importance of particular features are discussed. No significant differences in secondary chemistry were observed among the species.Many examples of convergence and some semi-cryptic species were revealed by molecular data. The term ‘semi-cryptic species’ is introduced here into lichenology for those species which cannot be clearly diagnosed by their morphology, but which are determined by other characters, mainly by their ecology and distribution. We propose to describe formally such species, in spite of difficulties with subsequent morphological identification.
A revision of the lichen genus Stirtonia
Authors: APTROOT André 
Published: September 2009

AbstractThe lichen genus Stirtonia has been revised. Thirteen species are accepted in the genus, including three new to science, viz. S. curvata from Irian Jaya and Java, S. schummii from the Seychelles and S. neotropica from Costa Rica and the Dutch Antilles. The known range of the genus is extended from Asian to pantropical. The genus is most diverse in the palaeotropics.

Published: September 2009

AbstractUmbilicaria ibericaandU. maculataare described as new to science on the basis of morphological and molecular data.Umbilicaria ibericais similar toU. polyphyllabut differs in having a monophyllous thallus with a distinctive white reticular pattern over the umbilicus and actinodisc apothecia.Umbilicaria maculatais similar toU. cylindricabut this new species is distinguished by its grey-brown thallus with sparse marginal cilia and white stains on the upper surface especially in the marginal zone, as well as by sessile apothecia with one or a few sterile fissures. Nuclear ITS and LSU rDNA have been used as molecular markers. In the phylogenetic analysisU. polyphyllafalls into two well supported clades (A and B), one of which corresponds to the morphotype that is described here as a new taxon. Specimens previously recognized asU.cylindricafall into three well supported clades: clade C corresponds to the typical morphotype, clade D corresponds to morphotype II described here as a new taxon, and clade E is morphotype III which is recognized asU.cf.umbilicarioides. Typical group I introns have been found in position 1506 of the nuclear SSU rDNA ofUmbilicaria; a consensus secondary structure of these introns is presented and we conclude that they represent an important and valuable molecular marker which gives additional support to the ITS and LSU sequence phylogeny obtained.

Published: September 2009

RÉSUMÉLa présente étude vise à déterminer si des différences existent entre les divers modèles de changement de culture (MCC) relativement à la perception du personnel soignant agréé à l’égard de l’accès aux structures d’habilitation et des prestations connues de soins individualisés. Nous avons embauché des employés qui travaillent dans des établissements ayant mis en œuvre les modèles sociaux de soins Eden Alternative, GentleCare ou Facility Specific ou n’ayant pas implanté de MCC. Nous avons effectué des analyses de variance multidimensionnelles de chacun des trois groupes de personnel soignant (infirmières autorisées, infirmières auxiliaires autorisées et aides-soignants) en fonction de chaque CCM. Les résultats indiquent qu’il existe des différences considérables entre le personnel soignant agréé et entre chacun des MCC. Plus le personnel soignant côtoie quotidiennement les patients, plus l’influence des MCC semble affecter l’autonomisation perçue et les prestations connues de soins individualisés. Des recherches suggèrent que les employés travaillant dans des établissements ayant mis en œuvre un des modèles sociaux de soins mentionnés ci-dessus profitent des meilleures conditions de travail. Inversement, parmi les établissements ayant implanté un de ces modèles, seul le personnel d’un établissement a fourni des réponses différentes de celles des employés travaillant dans des établissements sans MCC.
Community-Based Home Support Agencies: Comparing the Quality of Care of Cooperative and Non-profit Organizations

Published: September 2009

RÉSUMÉAu Québec, une combinaison d’organismes sans but lucratif et de coopératives offre des services d’entretien ménager, de préparation de repas et d’aide aux courses aux personnes âgées. Dans la présente étude, on pose la question suivante : les services offerts par les coopératives de services à domicile sont-ils de meilleure qualité que les services offerts par les organismes sans but lucratif? Cette étude permet également d’examiner les répercussions déterminées de la participation des bénéficiaires et des travailleurs et travailleuses au conseil d’administration. Les données ont été recueillies en 2006 et 2007 auprès de 831 personnes bénéficiaires de services à domicile, assurés par 9 coopératives et 9 organismes sans but lucratif. Deux instruments de mesure de la qualité centrés sur les bénéficiaires ont été utilisés : une échelle d’évaluation sommative de la qualité en 39 points et une note globale de qualité en 4 points. Les données ont été analysées par régression logistique. Les résultats révèlent que la structure organisationnelle n’est pas une variable explicative de la qualité, mais que la participation des travailleurs et des travailleuses au conseil d’administration est associée positivement à la note de satisfaction. De plus, la participation des bénéficiaires est associée positivement à la note de qualité globale.
Editorial: Realizing the Vision. The Canadian Longitudinal Study on Aging as a Strategic Initiative of the Canadian Institutes of Health Research
Authors: Martin-Matthews Anne , Mealing Linda 
Published: September 2009

RÉSUMÉL’Étude longitudinale canadienne sur le vieillissement (ÉLCV) a progressé à partir d’une vision lancée par l’Institut du vieillissement des IRSC en 2001 à une plateforme nationale de recherche subventionnée par le fédéral en 2008. Le développement du protocole d’ÉLCV a été mis en valeur par une série d’examens internationaux par les pairs, un comité de coordination multisectoriel, et un comité des IRSC des questions d’éthique, juridiques, et sociales; chacun était essentiel à l’excellence de la science et à rendre l’ÉLCV pertinente aux secteurs multiples. L’équipe de recherche de l’ÉLCV, menée par trois cochercheurs principaux (Kirkland, Raina, et Wolfson), a développé un protocole unique se concentrant sur le vieillissement de la cellule à la société – conçue pour suivre 50 000 personnes âgées entre 45 à 85 ans, sur une période de 20 ans années. Une association stratégique avec Statistique Canada a été cruciale au développement et au lancement de l’ÉLCV. L’ÉLCV contribuera à notre compréhension des transitions et de la trajectoire chez une population qui vieillit, et différera des études longitudinales du vieillissement dans le monde entier par rapport á l’ampleur de sa portée, le recrutement des moins âgés dans l’étude (âge 45), la diversité ethno-culturelle de la population du Canada, et au potentiel de lier des données rassemblées aux données administratives de santé au niveau provincial. L’étude d’IRSC est une étude novatrice longitudinale, basée sur la population, qui sera une ressource de recherche sans précédent soutenant la recherche multidisciplinaire et la prise de décision fondée sur des faits dans le domaine du vieillissement au Canada.

RÉSUMÉLes procédures diagnostiques cliniques standards sont souvent inappropriées et fréquemment non applicables dans des études basées sur la population; pourtant, vérifier le statut précis d’une maladie est essentiel. Nous avons fait une revue systématique pour identifier des algorithmes, des critères, et des outils utilisés pour identifier 17 maladies chroniques, et avons fait la praticabilité de développer des algorithmes pour l’ÉLCV. Des 29 616 citations examinées, 668 papiers ont rencontré tous les critères d’inclusion. Nous avons déterminé que l’information incluse dans un algorithme de maladie différera selon le type de condition. Le diagnostic de quelques conditions symptomatiques, telles l’arthrose et l’arthrite, exigera la justification par des critères cliniques (par exemple, rayons X, mesure de densité osseuse) tandis que d’autres conditions, telles la dépression, se baseront seulement sur les dires des individus. Les conditions asymptomatiques, telles l’hypertension, sont plus difficiles à vérifier par les dires des individus et exigeront des mesures physiologiques additionnelles (par exemple, tension artérielle) et des mesures de laboratoire (par exemple, glucose). Cette étude pilote a identifié les outils nécessaires pour développer des algorithmes d’évaluation de diagnostic.

RÉSUMÉLe but de l’Étude longitudinale canadienne sur le vieillissement (ÉLCV) est de recruter 50 000 participants âgés de 45 à 85 ans et de les suivre pendant 20 ans. Les processus d’échantillonnage et de recrutement pour une étude de cette envergure représentent d’importants défis. Statistique Canada a été approché pour collaborer avec l’ÉLCV dans le but de déterminer si l’Enquête sur la santé dans les collectivités canadiennes (ESCC) pourrait être utilisée comme véhicule de recrutement pour l’ÉLCV. Dans cette étude pilote réalisée en 2004, il a été déterminé que 63,8 pour cent et 75,8 pour cent des répondants accepteraient de partager leurs coordonnées et leurs réponses à l’ESCC avec l’ÉLCV, respectivement. Les réticences les plus souvent rapportées étaient reliées à la confidentialité, le manque d’intérêt et le niveau d’engagement demandé. Cette étude pilote a permis d’identifier quelques défis reliés à l’utilisation de l’ESCC comme véhicule de recrutement pour l’ÉLCV.

RÉSUMÉUne des clés au succès de l’Étude longitudinale canadienne sur le vieillissement (ÉLCV) sera de tirer profit des sources de données secondaires, en particulier données relatives à l’utilisation des soins de santé (USS). Pour examiner les aspects pratiques, méthodologiques et éthiques d’accéder à des données sur l’USS, des entrevues qualitatives individuelles ont été réalisés auprès de 53 administrateurs de données et commissaires/ombudsman à la protection de la vie privée à travers le Canada. Les participants de l’étude ont indiqué que d’obtenir la permission d’accéder à des données sur l’USS est généralement possible; cependant, ils ont noté que ce processus sera complexe et long, exigeant des travaux préparatoires considérables et méticuleux afin de s’assurer que la documentation soit appropriée et que le tout soit conforme aux variations juridiques ainsi qu’aux lignes, législatives et politiques.
Are nasal decongestants safer than rhinitis? A case of oxymetazoline-induced syncope
Authors: Fabi Marianna , Formigari Roberto , Picchio Fernando M. 
Published: September 2009

AbstractDerivatives of Imidazoline usually act to stimulate peripheral alpha2 receptors causing vasoconstriction. In young children, however, they can also stimulate alpha2receptors in the cardiovascular and central nervous systems, possibly causing cardiovascular, neurological, and respiratory depression. These medications do not require medical prescriptions, so often parents use them, bypassing paediatricians. We report here a case of cardiovascular and neurological depression induced by oxymetalzoline in a toddler.
