Ultrasound in the investigation of posterior compartment vaginal prolapse and obstructed defecation
Authors: Dietz H. P. , Beer‐Gabel M. 
Published: November 2011

AbstractRecent developments in diagnostic imaging have made gynecologists, colorectal surgeons and gastroenterologists realize as never before that they share a common interest in anorectal and pelvic floor dysfunction. While we often may be using different words to describe the same phenomenon (e.g. anismus/vaginismus) or attributing different meanings to the same words (e.g. rectocele), we look after patients with problems that transcend the borders of our respective specialties. Like no other diagnostic modality, imaging helps us understand each other and provides new insights into conditions we all need to learn to investigate better in order to improve clinical management.In this review we attempt to show what modern ultrasound imaging can contribute to the diagnostic work‐up of patients with posterior vaginal wall prolapse, obstructed defecation and rectal intussusception/prolapse. In summary, it is evident that translabial/perineal ultrasound can serve as a first‐line diagnostic tool in women with such complaints, replacing defecation proctography and MR proctography in a large proportion of female patients. This is advantageous for the women themselves because ultrasound is much better tolerated, as well as for healthcare systems since sonographic imaging is much less expensive. However, there is a substantial need for education, which currently remains unmet. Copyright © 2012 ISUOG. Published by John Wiley & Sons, Ltd.
The large-scale flow structure in turbulent rotating Rayleigh–Bénard convection
Authors: Weiss Stephan , Ahlers Guenter 
Published: November 2011

AbstractWe report on the influence of rotation about a vertical axis on the large-scale circulation (LSC) of turbulent Rayleigh–Bénard convection in a cylindrical vessel with aspect ratio $\Gamma \equiv D/ L= 0. 50$ (where $D$ is the diameter and $L$ the height of the sample). The working fluid is water at an average temperature ${T}_{av} = 40{~}^{\ensuremath{\circ} } \mathrm{C} $ with a Prandtl number $\mathit{Pr}= 4. 38$. For rotation rates $\Omega \lesssim 1~\mathrm{rad} ~{\mathrm{s} }^{\ensuremath{-} 1} $, corresponding to inverse Rossby numbers $1/ \mathit{Ro}$ between 0 and 20, we investigated the temperature distribution at the sidewall and from it deduced properties of the LSC. The work covered the Rayleigh-number range $2. 3\ensuremath{\times} 1{0}^{9} \lesssim \mathit{Ra}\lesssim 7. 2\ensuremath{\times} 1{0}^{10} $. We measured the vertical sidewall temperature gradient, the dynamics of the LSC and flow-mode transitions from single-roll states (SRSs) to double-roll states (DRSs). We found that modest rotation stabilizes the SRSs. For modest $1/ \mathit{Ro}\lesssim 1$ we found the unexpected result that the vertical LSC plane rotated in the prograde direction (i.e. faster than the sample chamber), with the rotation at the horizontal midplane faster than near the top and bottom. This differential rotation led to disruptive events called half-turns, where the plane of the top or bottom section of the LSC underwent a rotation through an angle of $2\lrm{\pi} $ relative to the main portion of the LSC. The signature of the LSC persisted even for large $1/ \mathit{Ro}$ where Ekman vortices are expected. We consider the possibility that this signature actually is generated by a two-vortex state rather than by a LSC. Whenever possible, we compare our results with those for a $\Gamma = 1$ sample by Zhong & Ahlers (J. Fluid Mech., vol. 665, 2010, pp. 300–333).

Published: November 2011

AbstractFor a Banach algebra 𝒜 and a character ϕ on 𝒜, we introduce and study the notion of essential ϕ-amenability of 𝒜. We give some examples to show that the class of essentially ϕ-amenable Banach algebras is larger than that of ϕ-amenable Banach algebras introduced by Kaniuth et al. [‘On ϕ-amenability of Banach algebras’, Math. Proc. Cambridge Philos. Soc.144 (2008), 85–96]. Finally, we characterize the essential ϕ-amenability of various Banach algebras related to locally compact groups.
Comparison of native and capric acid-enriched mustard oil effects on oxidative stress and antioxidant protection in rats
Authors: Sengupta Avery , Ghosh Mahua 
Published: November 2011

The present study evaluated the effect of mustard oil enriched in capric acid, a medium-chain fatty acid, on antioxidant enzyme activities in liver and brain and on the levels of malondialdehyde (MDA) in liver, brain and plasma in rats; the effect of adding cholesterol to the diet was also investigated. Charles Foster male albino rats weighing 80–100 g were fed one of four diets for 30 d (six rats per group). In the absence of added dietary cholesterol, the addition of capric acid to the diet resulted in lower plasma total cholesterol, non-HDL-cholesterol and TAG concentrations, higher HDL-cholesterol concentrations, higher antioxidant enzyme activities in liver and brain and lower MDA concentrations in liver, brain and plasma. Adding cholesterol to the diet increased plasma total cholesterol, non-HDL-cholesterol and TAG concentrations, decreased HDL-cholesterol concentration, decreased the activities of antioxidant enzymes and increased tissue and plasma MDA concentrations. Including capric acid in the diet of rats receiving cholesterol at least partly prevented the effects of the increased cholesterol. It is concluded that compared with native mustard oil, capric acid-enriched mustard oil improves blood lipids, enhances antioxidant protection and reduces lipid peroxidation.

Published: November 2011

n-3 Fatty acids are recognised as influencing both wound healing and immunity. We assessed the impact of a fish oil- and micronutrient-enriched formula (study formula) on the healing of pressure ulcers and on immune function in critically ill patients in an intensive care unit. A total of forty patients with pressure ulcers and receiving nutritional support were enrolled (intervention group, n 20, received study formula; and a control group, n 20, received an isoenergetic formula). Total and differential leucocyte count and percentage of adhesion molecule positive granulocyte and lymphocyte cells (CD11a, CD11b, CD18 and CD49b) were measured on days 0, 7 and 14. Percentage of positive lymphocytes for CD54, CD49b, CD49d and CD8 were also measured on days 0, 7 and 14. The state of pressure ulcers was assessed by using the pressure ulcer scale for healing tool score on days 7, 14 and 28 of treatment. No between-group differences in patient demographics, anthropometry or diagnostic class were observed. Patients who received the study formula showed significant increases in the percentage of positive CD18 and CD11a lymphocytes and of CD49b granulocytes as compared to controls (P < 0·05). While the severity of pressure ulcers was not significantly different between the two groups on admission, severity increased significantly over time for the control group (P < 0·05), but not for the study group. The present study suggests that a fish oil- and micronutrient-enriched formula may prevent worsening of pressure ulcers and that this effect may be mediated by an effect on adhesion molecule expression.

The objectives of the present study were to identify dietary patterns independently in first-time mothers and fathers, and to examine whether these patterns were correlated within families. Dietary intakes were collected at baseline in the Melbourne Infant Feeding Activity and Nutrition Trial Program using a validated FFQ in 454 pairs of first-time mothers and fathers. Education level was reported in associated questionnaires. Principal components analyses included frequencies of fifty-five food groups and were performed independently in mothers and fathers. Spearman's correlation coefficients were used to assess associations between dietary pattern scores. A total of four dietary patterns were identified in mothers and fathers. Of these, three dietary patterns had similar characteristics between these two populations, namely ‘Fruits and vegetables’, ‘High-energy snack and processed foods’, ‘High-fat foods’ in mothers; and ‘Fruits’, ‘High-energy snack and processed foods’, ‘High-fat foods’ in fathers. The following two additional patterns were identified: ‘Cereals and sweet foods’ in mothers and ‘Potatoes and vegetables’ in fathers. Patterns incorporating healthier food items were found to be positively associated with parent education. An inverse association with education was found for the ‘High-fat foods’ and ‘High-energy snack and processed foods’ dietary patterns. Qualitatively similar patterns between corresponding mothers and fathers were the most strongly correlated (ρ = 0·34–0·45, P < 0·001). There were some differences in dietary patterns between mothers and fathers, suggesting that it is worth deriving patterns separately when considering couples, and more generally between men and women. Exploring how these various patterns correlate within households provides important insights to guide the development and implementation of family-based interventions.
Suction sampling as a significant source of error in molecular analysis of predator diets

Published: November 2011

AbstractThe molecular detection of predation is a fast growing field, allowing highly specific and sensitive detection of prey DNA within the gut contents or faeces of a predator. Like all molecular methods, this technique is prone to potential sources of error that can result in both false positive and false negative results. Here, we test the hypothesis that the use of suction samplers to collect predators from the field for later molecular analysis of predation will lead to high numbers of false positive results. We show that, contrary to previous published work, the use of suction samplers resulted in previously starved predators testing positive for aphid and collembolan DNA, either as a results of ectopic contamination or active predation in the collecting cup/bag. The contradictory evidence for false positive results, across different sampling protocols, sampling devices and different predator-prey systems, highlights the need for experimentation prior to mass field collections of predators to find techniques that minimise the risk of false positives.
Convexity-preserving flows of totally competitive planar Lotka–Volterra equations and the geometry of the carrying simplex
Authors: Baigent Stephen 
Published: November 2011

AbstractWe show that the flow generated by the totally competitive planar Lotka–Volterra equations deforms the line connecting the two axial equilibria into convex or concave curves, and that these curves remain convex or concave for all subsequent time. We apply the observation to provide an alternative proof to that given by Tineo in 2001 that the carrying simplex, the globally attracting invariant manifold that joins the axial equilibria, is either convex, concave or a straight-line segment.
Conjugacies for impulsive equations
Authors: Barreira Luis , Valls Claudia 
Published: November 2011

AbstractFor impulsive differential equations, we construct topological conjugacies between linear and nonlinear perturbations of non-uniform exponential dichotomies. In the case of linear perturbations, the topological conjugacies are constructed in a more or less explicit manner. In the nonlinear case, we obtain an appropriate version of the Grobman–Hartman Theorem for impulsive equations, with a simple and direct proof that involves no discretization of the dynamics.
Pneumosinus dilatans, pneumocoele or air cyst? A case report and literature review
Authors: Teh B M , Hall C , Chan S W 
Published: November 2011

AbstractBackground:Pathological paranasal sinus expansion secondary to air is uncommon. However, this condition may be symptomatic or cosmetically apparent, requiring surgical intervention. Various terms have been used to describe this condition, and nomenclature is controversial.Method:An 18-year-old man presented with right facial pain, and was subsequently found to have pneumosinus dilatans of the maxillary sinus. A search was conducted of the PubMed, Medline and Embase databases, using the key words ‘pneumosinus dilatans’, ‘pneumoc(o)ele’, ‘pneumatoc(o)ele’ and ‘maxillary sinus’. Articles were also hand-searched. Relevant articles published in English were reviewed.Results:The literature review identified 36 cases involving the maxillary sinus (including the present case), with 19 cases reported as pneumosinus dilatans, 12 as pneumocoeles, two as pneumatocoeles, two as pneumosinus dilatans multiplex and one as an air cyst. However, based on the strict classification described by Urken et al., the majority of these cases should be reclassified as pneumocoeles.Conclusion:Whilst the nomenclature of this pathology is confusing, distinctions of terminology do not alter the management. Hence, we support the use of the term ‘air cyst’, to incorporate all these lesions.
Endoscopic treatment of glottic stenosis: a report on the safety and efficacy of CO2 laser
Authors: Riffat F , Palme C E , Veivers D 
Published: November 2011

AbstractBackground:Treatment of glottic stenosis is a considerable challenge to the otolaryngologist. Glottic airway patency can be compromised by bilateral vocal fold palsy, anterior webbing or a posterior segment scar, which may be significant enough to impair arytenoid movement.Method:A retrospective analysis of a prospective database of patients (n = 34) treated by a specialist airway surgeon. All patients underwent endoscopic treatment with a CO2 laser in an attempt to improve airway calibre and, in 12 patients, to decannulate tracheostomy tubes.Results:Twenty-one patients had bilateral vocal fold palsy and 13 had predominantly posterior glottic stenosis. A variety of pathology-directed treatment approaches were used to achieve good functional results. Four patients required a second endoscopic procedure. The overall revision rate was 5 per cent for bilateral fold palsy and 23 per cent for posterior glottic stenosis (p < 0.05). All patients had an adequate functional airway calibre, and all 12 tracheotomised patients were decannulated.Discussion:Pathology-directed endoscopic laser surgery is safe and effective treatment for glottic stenosis. Rather prescriptive use of unilateral or bilateral cordotomy or combined cordo-arytenoidectomy, clinicians must perform the procedure that will treat the lesion most adequately. Our success rate compared favourably with the best reported results.
Variability in the early life stages of juvenile plaice (Pleuronectes platessa) on west of Ireland nursery grounds: 2000–2007
Authors: Haynes Paula S. , Brophy Deirdre , McGrath David 
Published: November 2011

Plaice (Pleuronectes platessa) are the most abundant juvenile flatfish present on west of Ireland nursery grounds. 0-group plaice were collected from eleven sandy beach nursery areas along the west coast of Ireland by beach seining (2000–2007). In the majority of years examined, certain beaches were found to support a higher abundance of juvenile plaice, or individuals that were larger in size and exhibited good condition, suggesting that differences in habitat quality exist between beaches. Monthly mean densities of plaice ranged from 2.4 (± 2.4) to 100 (± 1.3) individuals 1000 m−2. Mean lengths of plaice ranged between 6.0 (± 1.0) and 10.1 (± 0.5) cm. No evidence of density dependent growth was detected over the eight years of the study. The length and condition of juvenile plaice also differed between hauls, indicating the existence of microhabitat effects and emphasizing the importance of selecting an appropriate spatial resolution to adequately assess an area. Similar to other locations in Europe, juvenile plaice abundances on nursery grounds were inversely related to mean spring seawater temperatures during the pelagic stage. Abundances of 0-group plaice were not related to the number of either 1- or 2-group individuals collected during bottom-trawl surveys off the Irish west coast, demonstrating the difficulties associated with developing a recruitment index for plaice.

BackgroundUnderstanding individual differences in susceptibility to antidepressant therapy side-effects is essential to optimize the treatment of depression.MethodWe performed genome-wide association studies (GWAS) to search for genetic variation affecting the susceptibility to side-effects. The analysis sample consisted of 1439 depression patients, successfully genotyped for 421K single nucleotide polymorphisms (SNPs), from the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. Outcomes included four indicators of side-effects: general side-effect burden, sexual side-effects, dizziness and vision/hearing-related side-effects. Our criterion for genome-wide significance was a prespecified threshold ensuring that, on average, only 10% of the significant findings are false discoveries.ResultsThirty-four SNPs satisfied this criterion. The top finding indicated that 10 SNPs inSACM1Lmediated the effects of bupropion on sexual side-effects (p=4.98×10−7,q=0.023). Suggestive findings were also found for SNPs inMAGI2,DTWD1,WDFY4andCHL1.ConclusionsAlthough our findings require replication and functional validation, this study demonstrates the potential of GWAS to discover genes and pathways that could mediate adverse effects of antidepressant medication.
The power to make others worship
Authors: SMUTS AARON 
Published: November 2011

AbstractCan any being worthy of worship make others worship it? I think not. By way of an analogy to love, I argue that it is perfectly coherent to think that one could be made to worship. However, forcing someone to worship violates their autonomy, not because worship must be freely given, but because forced worship would be inauthentic – much like love earned through potions. For this reason, I argue that one cannot be made to worship a fitting object; forced worship would be unfitting. My principal claim is that no being worthy of worship could exercise the power to make others worship it, since the act of making another worship would necessarily make one unworthy of worship.

RÉSUMÉUne partie de la stratégie de l’Ontario sur la maladie d’Alzheimer et les démences connexes (MADC) était de développer les priorités de recherche et de recommander des stratégies pour le renforcement des capacités de recherche. Le processus adopté pour atteindre ces objectifs comprenaient une analyse de l’environnement, des entretiens avec les informateurs clés, des enquêtes et un atelier de consensus ; ce processus a impliqué plus de 100 chercheurs, cliniciens, les personnes atteintes de démence précoce, et les aidants membres de familles. Ce document décrit le processus entrepris, les principaux problèmes identifiés et les recommandations pour les priorités de recherche et de renforcement des capacités de recherche ; il fournit également une orientation stratégique pour la recherche sur la démence en Ontario qui est pertinente pour d’autres juridictions. La recherche MADC dans tous ses aspects est nécessaire pour faire progresser la connaissance des causes de la démence, les soins et la guérison ; des lacunes existent actuellement dans la compréhension des approches efficaces pour les soins et le transfert des connaissances. La capacité pour la recherche de haut calibre reste sur le maintien de plans de carrière attractifs pour les chercheurs, des infrastructures solides et de partenariats forts. Afin que la recherche informera les politiques et pratiques, de meilleurs mécanismes seront nécessaires pour l’échange de connaissances.

SUMMARYIntroduction of pneumococcal polysaccharide (PPV23) and conjugate vaccine (PCV7) programmes were expected to change the epidemiology of invasive pneumococcal disease (IPD) and pneumonia in the UK. We describe the epidemiology of IPD and hospitalization with pneumonia using high-quality surveillance data over an 8-year period, 2002–2009. Although PPV23 uptake increased from 49% to 70% and PCV7 uptake reached 98% by 2009, the overall incidence of IPD increased from 11·8/100 000 to 16·4/100 000 (P=0·13), and the incidence of hospitalization with pneumonia increased from 143/100 000 to 207/100 000 (P<0·001). Although a reduction in the proportion of IPD caused by PCV7 serotypes was observed, concurrent increases in PPV23 and non-vaccine serotype IPD contributed to an increased IPD burden overall. Marked inequalities in the geographical distribution of disease were observed. Existing vaccination programmes have, so far, not been sufficient to address an increasing burden of pneumococcal disease in our locality.

SUMMARYThe aim of the present study was to assess the recent trends in the epidemiology of non-typhoidSalmonellain Israel using a sentinel laboratory-based surveillance network. Between 1999 and 2009, 8758Salmonellastool isolates were reported by five sentinel laboratories. There was a significant decrease in the incidence rate ofSalmonellaisolates from 70·5/100 000 in 1999 to 21·6/100 000 in 2005 followed by a slight increase to 30·3/100 000 in 2009. Of allSalmonella, 64·3% were isolated from children in the 0–4 years age group. Up to 2008,S. Enteritidis was the most prevalent serotype and in 2009S. Infantis emerged as the most commonSalmonellaserotype. The decrease in the incidence ofS. Enteritidis andS. Typhimurium and increase inS. Infantis among humans were associated with a similar trend among breeding flocks, which followed significant preventive interventions conducted againstS. Enteritidis andS. Typhimurium infections in poultry. Tight surveillance and education of food handlers and consumers should be enhanced to reduce the foodborne transmission ofSalmonellain Israel.
