Tele-ophthalmology Screening for Proliferative Diabetic Retinopathy in Urban Primary Care Offices: An Economic Analysis
Authors: Brady Christopher J. , Villanti Andrea C. , Gupta Omesh P. , Graham Mark G. , Sergott Robert C. 
Published: November 2014

BACKGROUND AND OBJECTIVE:
To determine whether tele-ophthalmology screening for proliferative diabetic retinopathy (PDR) can be cost-saving.

PATIENTS AND METHODS:
Adults with diabetes presenting for routine medical care underwent non-mydriatic fundus photography with remote grading. Direct medical costs were estimated using the Medicare fee schedule in the base case, with Medicaid and commercial insurance rates used for low and high values, respectively. One-way and probabilistic sensitivity analyses were performed.

RESULTS:
Of 99 participants, at least mild retinopathy was found in 24 (24.2%). Urgent consultation was recommended for eight participants (8.1%) for possible vision-threatening diabetic retinopathy, including two participants (three eyes) with PDR. In the base case, screening saved $36 per patient. A Monte Carlo simulation indicated that screening saved a median of $48 per patient.

CONCLUSION:
A substantial burden of diabetic retinopathy was identified, most of which was undiagnosed. In a closed system, tele-ophthalmology screening for PDR is likely to be cost-saving across the range of scenarios explored.

Bilateral Central Serous Chorioretinopathy Associated With Estrogen Modulator Diindolylmethane
Authors: Bussel Igor I. , Lally David R. , Waheed Nadia K. 
Published: November 2014

Central serous chorioretinopathy (CSCR) is an idiopathic disease associated with states of hypercortisolism that causes fluid to collect under the retina resulting in visual impairment. The authors describe an otherwise healthy female patient who presented with headaches and blurry vision after a 2-month history of excessive daily consumption of diindolylmethane (DIM), an over-the-counter estrogen modulator medication used to treat facial acne. Imaging demonstrated asymmetric, bilateral CSCR with active leakage in the left eye. She was instructed to discontinue DIM and reported that visual improvement began 2 weeks after, with resolution to baseline after 8 weeks.[Ophthalmic Surg Lasers Imaging Retina.2014;45:589–591.]
Spectral Flow for Nonunital Spectral Triples
Authors: Carey A. L. , Gayral V. , Phillips J. , Rennie A. , Sukochev F. A. 
Published: November 2014

AbstractWe prove two results about nonunital index theory left open in a previous paper. The
first is that the spectral triple arising from an action of the reals on a C*-algebra with invariant trace satisûes the hypotheses of the nonunital local index formula. The second result concerns the meaning of spectral flow in the nonunital case. For the special case of paths arising from the odd index pairing for smooth spectral triples in the nonunital setting, we are able to connect with earlier approaches to the analytic definition of spectral flow
Outer Partial Actions and Partial Skew Group Rings
Authors: Nystedt Patrik , Öinert Johan 
Published: November 2014

AbstractWe extend the classical notion of an outer action α of a group G on a unital ring A to the case when α is a partial action on ideals, all of which have local units. We show that if α is an outer partial action of an abelian group G, then its associated partial skew group ring A *α G is simple if and only if A is G-simple. This result is applied to partial skew group rings associated with two different types of partial dynamical systems.
Live Music Promotes Positive Behaviours in People with Alzheimer's Disease
Authors: Cox Elissa , Nowak Madeleine , Buettner Petra 
Published: November 2014

Introduction: Behavioural symptoms of Alzheimer's disease present barriers to providing a holistic standard of care. Limited attention has been given to the potential effects of live music, rather than background music or music therapy, on mood, function, and participation in and performance of daily activities. This exploratory study investigated whether live music could facilitate the expression of positive behaviour in people with Alzheimer's disease. Method: A live musical violin intervention, provided on a one-to-one basis in a residential care facility, was employed to assess positive behaviour in people with moderate-to-severe Alzheimer's disease using a one-group repeated measures design. Seven participants were video-recorded before, during, and after the intervention, which was provided individually in three separate sessions. The investigator and a blinded assessor used an investigator-modified version of the Cohen-Mansfield Agitation Inventory to assess 16 positive behaviours. Quotations from study participants are presented. Data were analysed using the Friedman test. Results: The total number of positive behaviours increased significantly from a median number of 4.3 (range 1.3–13) before the intervention to 30 (range 13–47.7) during, and 24.3 (range 4–27.7) after the intervention (p = 0.001). Conclusion: Live individualized music may provide occupational therapists with a useful strategy to enrich the lives of people with Alzheimer's disease.
Occupational Therapy for People Living with a Life-Limiting Illness: A Thematic Review
Authors: Hammill Kathrine , Bye Rosalind , Cook Catherine 
Published: November 2014

Introduction: Little is known about occupational therapy practice for people with a life-limiting illness. This paper aims to review the available occupational therapy literature in order to develop a greater understanding of the role and practice trends of occupational therapists working in this area. Methods: A systematic search of literature published from 1975–2013 was conducted. Three hundred and fifty-five pieces of literature were located and screened for inclusion using a three-stage process. All literature that met the inclusion criteria was then analysed thematically. Findings: An in-depth review of 52 articles, three position statements, two key occupational texts, and one clinical guideline identified three themes in the literature. These themes comprised: (i) reframing practice: defining a palliative approach in occupational therapy; (ii) continuing occupational engagement despite loss; and (iii) preparing for practice when your client is dying: educational requirements of occupational therapists. Conclusion: Occupational therapy has an important role to play in the care of people with a life-limiting illness. However, knowledge gaps remain concerning the scope of the role and how best to engage clients in meaningful occupations at the end of life. Further education is required at the undergraduate level and for clinicians working in this area.

Ecological response of Cedrus atlantica to climate variability in the Massif of Guetiane (Algeria)
Authors: Slimani Said , Derridj Arezki , Gutierrez Emilia 
Published: November 2014

Aim of the study: The study analyzes the long-term response of Atlas cedar, Cedrus atlantica (Manneti), to climate variability. Area of study: Atlas cedar forest of Guetiane (Batna, Algeria).Material and methods: The dendrochronological approach was adopted. An Atlas cedar tree-ring chronology was established from twenty trees. The response of the species to climate variability was assessed through the pointer years (PYs), the common climate signal among the individual chronologies, expressed by the first component (PC1), the mean sensitivity (msx), and response function and correlations analysis involving the tree-ring index and climate data (monthly mean temperature and total precipitation).Results: The highest growth variability was registered from the second half of the 20th century. The lower than the mean PYs, the PC1, and the msx increased markedly during the studied period. Dramatic increases in the PC1 and msx were detected at the end of the 1970s, reflecting a shift towards drier conditions enhancing an increasing trend towards more synchronous response of trees to climate conditions. The response function and correlations analysis showed that tree growth was mainly influenced by precipitation variability.Research highlights: Our findings provide baseline knowledge concerning the ecological response of Atlas cedar to climate variability in in its southern distribution limit, where a high level of tree mortality has been observed during recent decades, coinciding with the driest period Algeria has ever experienced. This information is vital to support ongoing ecosystem management efforts in the region. Keywords: Atlas cedar; annual growth variability; dieback; dendrochronology.

Toezichthouders op straat
De zorg voor veiligheid wordt niet meer gezien als exclusieve taak van de politie. Naast de politie zijn andere, zowel publieke als private toezichthouders en handhavers werkzaam in de (semi)publieke ruimte. Dit gebeurt niet alleen in Nederland, maar ook in veel andere landen, zowel binnen als buiten Europa. Vaak leidt dat tot een gefragmentariseerd stelsel van handhaving. Het internationale vergelijkende onderzoek dat in dit artikel wordt gepresenteerd, biedt aanknopingspunten om te leren van ervaringen die in andere landen zijn opgedaan. Tevens worden twee opties besproken waarin wordt aangegeven hoe de coördinatie kan worden verbeterd.
Cibles du traitement des joueurs problématiques : existe-t-il des différences entre les hommes et les femmes ?

Published: November 2014

Selon les dernières études de prévalence, plus de 160 000 Québécois et Québécoises souffrent de problèmes de jeu de hasard et d’argent, ce qui représente près de 2 % de la population de la province. Cette problématique touche en général deux hommes pour une femme et il semblerait que l’étiologie et les profils de difficultés soient différents selon le sexe de la personne atteinte. Certaines études rapportent que ces différences engendreraient la nécessité d’offrir des interventions différentes selon que les joueurs problématiques sont de sexe féminin ou masculin. Mais, est-ce vraiment le cas ? Les différences présentes selon le sexe sont-elles réellement synonymes d’un besoin d’intervention différent ? La présente étude tente de répondre à cette interrogation en dressant d’abord les profils sociodémographiques et de difficultés de joueurs problématiques en fonction de leur sexe. L’étude compare ensuite l’estimation du besoin d’intervention à ces sphères selon que l’usager est de sexe féminin ou masculin. Pour ce faire, les évaluations d’entrée du Centre de réadaptation en dépendance de Québec (Indice de gravité d’une toxicomanie ; IGT) de 190 joueurs problématiques adultes, 125 hommes et 65 femmes, sont analysées. Les analyses statistiques démontrent des différences significatives entre les sexes quant aux profils sociodémographiques, aux habitudes de jeu de hasard et d’argent et à l’état psychologique. Cependant, aucune différence significative n’est observée entre les besoins d’intervention estimés par les évaluateurs et ceux estimés par les usagers sur ces différentes sphères. Ces résultats suggèrent donc que les usagers témoignent de besoins d’intervention semblables aux différentes sphères de vie évaluées par l’IGT, et ce, malgré des profils sociodémographiques et des profils de difficultés différents selon leur sexe.
Rationaliser les comportements de jeu
Authors: Gadbois Jocelyn 
Published: November 2014

Cet article de réflexion théorique cherche à rationaliser les comportements des joueurs québécois de Lotto 6/49. Après avoir constaté les limites des théories sur le jeu de la psychologie cognitivo-comportementale, l’auteur propose un nouveau cadre d’analyse inspiré de la perspective intersubjective de Maurice Allais dans lequel les croyances des joueurs sont étudiées comme faisant partie intégrante de l’expérience de jeu. Il met de l’avant deux indicateurs pour estimer comme étant rationnelle la décision de jouer : 1) elle doit être cohérente avec la réalité vécue du joueur et 2) elle doit s’inscrire dans une quête de satisfaction. Sa démonstration s’appuie sur l’étude de neuf cas issus d’un corpus de 200 entrevues ouvertes menées à Québec en hiver 2010. Ces cas illustrent comment trois croyances sur le jeu (le systémisme, le pouvoir maléfique du gros lot et la participation des morts) peuvent être vécues de manière bien différente. Son interprétation rappelle l’importance de considérer l’expérience du joueur pour faire avancer les connaissances.

Objetivo: O objetivo deste estudo foi investigar a associação entre a condição de saúde bucal materna, parto pré-termo e/ou baixo peso de recém-nascido, e avaliar as condições socioeconômicas das puérperas. Materiais e Métodos: Um estudo transversal foi realizado em Diamantina (MG). A amostra foi constituída de 200 parturientes que foram entrevistadas e examinadas no pós-parto. As seguintes variáveis foram investigadas: baixo peso ao nascer e parto pré-termo, registro periodontal simplificado (PSR), índice de dentes cariados, perdidos e obturados (CPOD) e índice de placa das mães. Dados sobre as condições sócioeconômicas relativas às mães foram coletados através de questionário e prontuários hospitalares. Foram realizados testes t e Mann- Whitney para a análise estatística dos dados, assim como regressão logística múltipla, ajustada pelas variáveis idade, renda e escolaridade. Resultados: Foram entrevistadas 200 puérperas, sendo que 12 tiveram parto prétermo e 19 tiveram recém-nascido de baixo peso. Do total de entrevistadas, 12 fumavam e 24 eram etilistas. O índice CPOD médio encontrado foi de 11,94 (±6,56). Houve associação entre recém-nascido de baixo peso com fumo (p = 0,03), álcool (p < 0,01), condição periodontal (p = 0,01) e CPOD (p = 0,03). Uma mãe comPSR superior a 2 teve 3,29 mais chances de ter um filho com baixo peso. Não houve associação entre parto pré-termo e nenhuma das variáveis investigadas. Conclusão: Tanto o índice PSR quanto o CPOD das mães associaram-se com recém-nascidos de baixo peso, mas não com partos pré-termo.Descritores: Doença periodontal. Trabalho de parto prematuro.

ObjectivesTo determine whether bowel wall fibrosis can be detected in freshly resected human intestinal specimens based on ultrasound‐derived shear wave speed.MethodsSeventeen intact (>3‐cm) bowel segments (15 small and 2 large intestine) from 12 patients with known or suspected inflammatory bowel disease were procured immediately after surgical resection. Ultrasound shear wave elastography of the bowel wall was performed by two methods (Virtual Touch Quantification [VTQ] and Virtual Touch‐IQ [VT‐IQ]; Siemens Medical Solutions USA, Inc, Mountain View, CA). Eighteen short‐axis shear wave speed measurements were acquired from each specimen: 3 from the 9‐, 12‐, and 3‐o'clock locations for each method. Imaging was performed in two areas for specimens greater than 10 cm in length (separated by ≥5 cm). A gastrointestinal pathologist scored correlative histologic slides for inflammation and fibrosis. Differences in mean shear wave speed between bowel segments with low and high inflammation/fibrosis scores were assessed by a Student t test. Receiver operating characteristic curve analysis was performed.ResultsHigh–fibrosis score (n = 11) bowel segments had a significantly greater mean shear wave speed than low–fibrosis score (n = 6) bowel segments (mean ± SD: VTQ, 1.59 ± 0.37 versus 1.18 ± 0.08 m/s; P= .004; VT‐IQ, 1.87 ± 0.44 versus 1.50 ± 0.26 m/s; P= .049). There was no significant difference in mean shear wave speed between high–and low–inflammation score bowel segments (P > .05 for both VTQ and VT‐IQ). Receiver operating characteristic curves showed areas under the curve of 0.91 (95% confidence interval, 0.67–0.99) for VTQ and 0.77 (95% confidence interval, 0.51–0.94) for VT‐IQ in distinguishing low–from high–fibrosis score bowel segments.ConclusionsEx vivo bowel wall shear wave speed measurements increase when transmural intestinal fibrosis is present.

ObjectivesIntracranial pressure usually increases after severe brain injury. However, a method for noninvasive evaluation of intracranial pressure is still lacking. The purpose of this study was to explore the potential role of transcranial color Doppler sonography in assessing intracranial pressure by observing the middle cerebral artery blood flow parameters in patients with increased intracranial pressure of varying etiology.MethodsThe hemodynamic changes in the middle cerebral artery in patients with varying degrees of increased intracranial pressure were investigated by transcranial color Doppler sonography in 93 patients who had emergency surgery for brain injury.ResultsMiddle cerebral artery Doppler flow spectra changed regularly as intracranial pressure increased. The pulsatility index (PI) and resistive index (RI) had a significantly positive correlation with intracranial pressure (r = 0.90 and 0.89, respectively; P< .001), whereas the middle cerebral artery diastolic velocity showed a significant negative correlation with intracranial pressure (r = −0.52; P< .01). A receiver operating characteristic curve showed that the RI and PI cutoff values were 0.705 and 1.335, respectively, for predicting increased intracranial pressure, with sensitivity of 0.885 and specificity of 0.970.ConclusionsIn addition to the PI and RI, middle cerebral artery diastolic flow velocity measurement by transcranial color Doppler sonography may also be a useful variable for evaluating intracranial pressure in patients with acute brain injury.
A Deep Cabled Observatory: Biology and Physics in the Abyss
Authors: Howe Bruce M. 
Published: November 2014

The ALOHA Cabled Observatory (ACO) is the deepest operating observatory on the planet, providing power and communications to scientific instruments on the seafloor. In the future, ACO will add water column measurements, from the seafloor to the surface, using moorings and undersea vehicles. Recent results from video monitoring of deep‐sea life and from temperature sensors illustrate the benefit of and need for long‐term, sustained, continuous sampling in this abyssal context. The observatory is located at Station ALOHA (A Long‐Term Oligotrophic Habitat Assessment), 100 kilometers north of Oahu, at 4728‐meter water depth (Figure 1, top).
Deuterium excess in subtropical free troposphere water vapor: Continuous measurements from the Chajnantor Plateau, northern Chile
Authors: Samuels‐Crow Kimberly E. , Galewsky Joseph , Sharp Zachary D. , Dennis Kate J. 
Published: November 2014

AbstractWater vapor measured continuously by cavity ring‐down spectroscopy from July 2012 to March 2013 on the hyperarid Chajnantor Plateau, northern Chile (elevation = 5080 m, pressure ≈ 550 hPa), has a mean deuterium excess (d‐excess = δD − 8*δ18O) of 46‰ ± 5‰ and frequently exceeds 100‰ at low water vapor mixing ratios (q ≤ 500 ppmv). These measurements provide empirical support for theoretical predictions of free troposphere d‐excess. The d‐excess measured at this site can be understood in terms of supersaturation with respect to ice at relative humidities between 100% and 130%, followed by mixing with moist midtropospheric or lower tropospheric air en route to the plateau. The d‐excess measured at Chajnantor is consistent with predictions for d‐excess in the upper troposphere from isotope‐enabled general circulation models and with high vapor saturation over ice in cloud‐resolving and microphysical models.

Published: November 2014

AbstractBased on the coordinated observations by the incoherent scatter radar (ISR), ionosonde, magnetometers, and GPS receivers, the electrodynamic effects on the equatorial and low‐latitude ionosphere have been investigated during the intense solar flare (X1.5/2B) on 13 September 2005. In the initial stage of the flare, the ISR and ionosonde measurements at Jicamarca show the decreases of 10.14 m/s and 20 km in the upward vertical E × B drift velocity and the F2 region peak height, respectively, while equatorial electrojet (EEJ) strength over American sector indicates a sudden increase of 53.7 nT. The decrease of the upward vertical E × B drift velocity reveals the weakening of eastward electric field during the flare, which is firstly and directly observed by instrument. It is well known that the variation of equatorial electric field is mainly attributed to the ionospheric dynamo electric field and partially affected by the penetration of interplanetary electric field. The observations during this flare suggest that the flare‐induced increase of Cowling conductivity changes the ionospheric dynamo electric field and further results in the weakening of eastward electric field and the decrease of the upward vertical E × B drift velocity. Meanwhile, the upward vertical E × B drift velocity and the EEJ strength during the flare are negatively correlated, which is contrary to the knowledge established by Anderson et al. () based on 10 days of observations in the Peruvian longitude sector. The difference may be caused by the flare‐induced enhancement of Cowling conductivity. In addition, GPS total electron content (TEC) observations from six stations in the American equator and low latitudes show an enhancement of 1.47–3.09 TEC units. The measurements of GPS and ISR indicate that the contribution of the enhanced photoionization to the increase of TEC is more than that of electrodynamic effect during the initial stage of the intense flare.
