Published: January 2013

AbstractBackground and objectiveTransbronchial lung biopsies remain the gold standard to establish the presence of allograft rejection or infection after lung transplantation. The aim of this study was to evaluate the efficacy and safety of cryo‐transbronchial biopsies (cryo‐TBB) in lung transplantation patients.MethodsForty lung transplantation patients (mean age 58.3 years) underwent cryo‐TBB, either routine post lung transplantation surveillance bronchoscopy (n = 27), or clinically indicated bronchoscopy (n = 13). During the procedure, two to three biopsy samples were taken. Procedure characteristics, complications and the diagnostic yield were compared with 40 matched controls who underwent conventional forceps‐TBB.ResultsNo major complications occurred in the cryo‐TBB group. The mean diameter of the specimen taken by cryo‐TBB was 10 mm2 compared with only 2 mm2 using forceps‐TBB (P < 0.05). The increased size and quality of biopsy samples in the study group translated to a significant increase in the percentage of alveolated tissue (65% vs 34% respectively, P < 0.05) that enabled a clear histological detection of acute rejection (n = 4), pneumonitis (n = 3), diffuse alveolar damage (n = 1) and confident exclusion of acute rejection, infection or pneumonitis (n = 32). Fluoroscopy time was significantly shorter in the cryo‐biopsy patients compared with controls (25 s vs 90 s, respectively, P < 0.05).ConclusionsCryo‐TBB for both surveillance and clinically indicated bronchoscopy in lung transplantation patients provides larger and more diagnostic lung parenchyma specimens with low complication rate and shorter intervention time than traditional forceps biopsies.
Variation in oral health parameters between older people with and without mental disorders

Published: January 2013

ABSTRACTThis study investigated the variation in the oral examination findings and the subjective oral complaints between older people with and without mental disorders. An interview and an oral investigation were performed in a group of older patients with mental disorders with a mean age of 71.9 years and in a group of older people without mental disease with a mean age of 70.2 years. The analysis did not reveal any statistically significant differences in the dental status of the participants and in the prevalence of oral ulcers and stomatitis. However xerostomia, burning mouth, dysgeusia, and oral malodor complaints were more frequent in patients with mental disorders, whereas general chewing complaints were less frequent. The multiple logistic regression analysis revealed that psychiatric illness was significantly associated with more complaints of dysgeusia and fewer chewing complaints. The increased prevalence of specific oral complaints in the older patients with mental disorders revealed the significant psychopathological compound of these symptoms.

AbstractObjectiveThe microbiologic causes of bloodstream infections (BSI) may differ between HIV‐positive and HIV‐negative patients and direct initial empiric antibiotic treatment (i.e. treatment before culture results are available). We retrospectively assessed community‐acquired BSI episodes in adults in Cambodia according to HIV status for spectrum of bacterial pathogens, antibiotic resistance patterns and appropriateness of empiric antibiotics.MethodsBlood cultures were systematically performed in patients suspected of BSI in a referral hospital in Phnom Penh, Cambodia. Data were collected between 1 January 2009 and 31 December 2011.ResultsA total of 452 culture‐confirmed episodes of BSI were recorded in 435 patients, of whom 17.9% and 82.1% were HIV‐positive and HIV‐negative, respectively. Escherichia coli accounted for one‐third (n = 155, 32.9%) of 471 organisms, with similar rates in both patient groups. Staphylococcus aureus and Salmonella cholereasuis were more frequent in HIV‐positive vs. HIV‐negative patients (17/88 vs. 38/383 (P = 0.02) and 10/88 vs. 5/383 (P < 0.001)). Burkholderia pseudomallei was more common in HIV‐negative than in HIV‐positive patients (39/383 vs. 2/88, P < 0.001). High resistance rates among commonly used antibiotics were observed, including 46.6% ceftriaxone resistance among E. coli isolates. Empiric antibiotic treatments were similarly appropriate in both patient groups but did not cover antibiotic‐resistant E. coli (both patient groups), S. aureus (both groups) and B. pseudomallei (HIV‐negative patients).ConclusionThe present data do not warrant different empiric antibiotic regimens for HIV‐positive vs. HIV‐negative patients in Cambodia. The overall resistance rates compromise the appropriateness of the current treatment guidelines.
Capillary versus venous haemoglobin determination in the assessment of healthy blood donors
Authors: Patel A. J. , Wesley R. , Leitman S. F. , Bryant B. J. 
Published: January 2013

Background and ObjectivesTo determine the accuracy of fingerstick haemoglobin assessment in blood donors, the performance of a portable haemoglobinometer (HemoCue Hb 201+) was prospectively compared with that of an automated haematology analyzer (Cell‐Dyn 4000). Haemoglobin values obtained by the latter were used as the ‘true’ result.Material and MethodsCapillary fingerstick samples were assayed by HemoCue in 150 donors. Fingerstick samples from two sites, one on each hand, were obtained from a subset of 50 subjects. Concurrent venous samples were tested using both HemoCue and Cell‐Dyn devices.ResultsCapillary haemoglobin values (HemoCue) were significantly greater than venous haemoglobin values (HemoCue), which in turn were significantly greater than venous haemoglobin values by Cell‐Dyn (mean ± SD: 14·05 ± 1·51, 13·89 ± 1·31, 13·62 ± 1·23, respectively; P < 0·01 for all comparisons among groups). Nine donors (6%) passed haemoglobin screening criteria (≥12·5 g/dl) by capillary HemoCue, but were deferred by Cell‐Dyn values (false‐pass). Five donors (3%) were deferred by capillary sampling, but passed by Cell‐Dyn (false‐fail). Substantial variability in repeated fingerstick HemoCue results was seen (mean haemoglobin 13·72 vs. 13·70 g/dl, absolute mean difference between paired samples 0·76 g/dl). Hand dominance was not a factor.ConclusionsCapillary samples assessed via a portable device yielded higher haemoglobin values than venous samples assessed on an automated analyzer. False‐pass and false‐fail rates were low and acceptable in the donor screening setting, with ‘true’ values not differing by a clinically significant degree from threshold values used to assess acceptability for blood donation.
Numerical-symbolic exact irreducible decomposition of cyclic-12
Authors: Sabeti Rostam 
Published: January 2013

AbstractIn 1992, Göran Björck and Ralf Fröberg completely characterized the solution set of cyclic-8. In 2001, Jean-Charles Faugère determined the solution set of cyclic-9, by computer algebra methods and Gröbner basis computation. In this paper, a new theory in matrix analysis of rank-deficient matrices together with algorithms in numerical algebraic geometry enables us to present a symbolic-numerical algorithm to derive exactly the defining polynomials of all prime ideals of positive dimension in primary decomposition of cyclic-12. Empirical evidence together with rigorous proof establishes the fact that the positive-dimensional solution variety of cyclic-12 just consists of 72 quadrics of dimension one.

This paper [1], which was published online on 1 June 2011, has been retracted by agreement between the authors, the journal’s Editor-in-Chief Derek Holt, the London Mathematical Society and Cambridge University Press. The retraction was agreed to prevent other authors from using incorrect mathematical results. (In this paper, we compute and verify the positivity of the Li coefficients for the Dirichlet $L$-functions using an arithmetic formula established in Omar and Mazhouda, J. Number Theory 125 (2007) no. 1, 50–58; J. Number Theory 130 (2010) no. 4, 1109–1114. Furthermore, we formulate a criterion for the partial Riemann hypothesis and we provide some numerical evidence for it using new formulas for the Li coefficients.)
Abelian functions associated with genus three algebraic curves
Authors: Eilbeck J. C. , England M. , Ônishi Y. 
Published: January 2013

AbstractWe develop the theory of Abelian functions associated with algebraic curves. The growth in computer power and the advancement of efficient symbolic computation techniques have allowed for recent progress in this area. In this paper we focus on the genus three cases, comparing the two canonical classes of hyperelliptic and trigonal curves. We present new addition formulae, derive bases for the spaces of Abelian functions and discuss the differential equations such functions satisfy.Supplementary materials are available with this article.
Examples of linear multi-box splines
Authors: Bettayeb Abdellatif 
Published: January 2013

AbstractLet S1=S1(v0,…,vr+1) be the space of compactly supported C0 piecewise linear functions on a mesh M of lines through ℤ2 in directions v0,…,vr+1, possibly satisfying some restrictions on the jumps of the first order derivative. A sequence ϕ=(ϕ1,…,ϕr) of elements of S1 is called a multi-box spline if every element of S1 is a finite linear combination of shifts of (the components of) ϕ. We give some examples for multi-box splines and show that they are stable. It is further shown that any multi-box spline is not always symmetric
Algorithmic construction of Chevalley bases
Authors: Magaard K. , Wilson R. A. 
Published: January 2013

AbstractWe present a new algorithm for constructing a Chevalley basis for any Chevalley Lie algebra over a finite field. This is a necessary component for some constructive recognition algorithms of exceptional quasisimple groups of Lie type. When applied to a simple Chevalley Lie algebra in characteristic p⩾5, our algorithm has complexity involving the seventh power of the Lie rank, which is likely to be close to best possible.
Cardiac effect of short‐term experimental weight gain and loss in dogs
Authors: Pelosi A. , Rosenstein D. , Abood S. K. , Olivier B. N. 
Published: January 2013

During 12 weeks, 18 normal dogs were fed a high‐caloric diet intended to induce obesity (weight‐gain phase). For the next 12weeks (weight‐loss phase), all dogs were fed a diet calculated to provide maintenance needs. During this second phase, dogs were randomly assigned to three groups differing only in their exercise regimen: group 1 dogs were not exercised, group 2 dogs were exercised three times each week on a treadmill, group 3 dogs were similarly exercised and outfitted with a vest holding additional weights. Echocardiographic data were obtained at baseline and following both the weight‐gain and weight‐loss phases. The weight‐gain phase of the study was associated with an increase in bodyweight (31.4 per cent), decrease in body density (3.9 per cent) and an increase in left ventricular (LV) myocardial cross‐sectional area in all groups. Cardiac hypertrophy was variably reversible during the weight‐loss phase, with complete recovery for group 1, partial recovery for group 2 and no recovery in group 3. Regardless of group, weight loss was associated with a significant increase in LV diameter, a reduction of heart rate and an increase in heart rate‐corrected isovolumetric relaxation time.
The six-eyed sand spiders of the genus Sicarius (Araneae: Haplogynae: Sicariidae) from the Brazilian Caatinga
Authors: MAGALHÃES IVAN L. F. , BRESCOVIT ANTONIO D. , SANTOS ADALBERTO J. 
Published: January 2013

In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp. We report high intraspecific variation in the genitalic morphology of these species, especially in females. We also provide anecdotal observations on natural history and behavior of these species, including diet, mating behavior and clutch size. We include an identification key for Brazilian Caatinga species of Sicarius.
A new genus and some new species of the genus Lauriea Baba, 1971 (Crustacea, Decapoda, Galatheidae) from the Pacific and Indian Oceans, using molecular and morphological characters
Authors: MACPHERSON ENRIQUE , ROBAINAS-BARCIA AYMEE 
Published: January 2013

The genus Lauriea belongs to the family Galatheidae and is easily differentiated from other genera of the family by the endopod of the uropod being much wider than long and the dactyli of the walking legs being curved and strongly biunguiculate. Examination of many specimens collected during recent expeditions from Madagascar to French Polynesia and using morphological and molecular data revealed the existence of six species, five of them new, that are genetically distinct yet morphologically very similar. Furthermore, another new species, having a triunguiculate P2–4 dactyli, represents a new genus, Triodonthea.
Reclassification of the Indo-Pacific Hawkfish Cirrhitus pinnulatus (Forster)
Authors: GAITHER MICHELLE R. , RANDALL JOHN E. 
Published: January 2013

The hawkfish Cirrhitus pinnulatus Forster (in Bloch & Schneider 1801) was regarded as one wide-ranging Indo-Pacific species, from the Red Sea and east coast of Africa to the Hawaiian Islands and the islands of French Polynesia. Schultz (1950) resurrected the name C. alternatus Gill for the population in the Hawaiian Islands and Johnston Atoll, and described the Red Sea population as a new species, C. spilotoceps, based on morphological data. Randall (1963) confirmed the differences that Schultz used to separate Cirrhitus pinnulatus into three species, but preferred to regard them as subspecies. We examined more specimens, colour photographs, and used genetic comparisons to determine the validity of the three species recognized by Schultz (1950). Combining mitochondrial cytochrome oxidase I and cytochrome b sequence data from specimens of C. pinnulatus pinnulatus from the Indo-Pacific, C. spilotoceps from the Red Sea, and C. pinnulatus maculosus from Hawai‘i, we detected levels of sequence divergence (5–12%) that support the species-level designation of C. spilotoceps. We detected no genetic differentiation but maintain the subspecies designation of the Hawaiian form based on morphological and colour differences. We found a third genetic lineage in the Indian Ocean and Western Pacific that is 5% divergent from C. spilotoceps. We refrain from designating this group as a separate subspecies until further morphological and genetic study can be completed.
Diabetes nursing: a personal reflection of the last 60 years
Authors: Mackinnon Mary 
Published: January 2013

This reflection follows a personal perspective of diabetes nursing over the previous 60 years published in this journal coinciding with the Queen’s 60th Jubilee in 2012. Diabetes nursing continues to progress with specialist nurses providing high quality evidence based practice. Over the last ten years, the diabetes ‘scene’ has become even more complex with the advent of new technologies, complex therapies, structured diabetes education programmes, a changing NHS and an even greater need to reduce costs. Training and continuing education for those providing care and support is essential if people with diabetes and those close to them, are to become ‘experts’ at managing their diabetes.

Diabetic ketoacidosis and diabetic pregnancy: hard won victories
Authors: Tattersall Robert 
Published: January 2013

Histories of diabetes often claim that the introduction of insulin in 1922 immediately revolutionised the treatment of diabetic ketoacidosis and diabetic pregnancy. How far from the mark this grand narrative of progress is can be seen from the fact that 30 years later, at the time of Queen Elizabeth’s accession, a woman with diabetes had slightly better than a 50:50 chance of having a live baby and the mortality of ketoacidosis in many hospitals was 30-50%. Improvement of the prognosis in both conditions was as much due to good organisation as to new scientific principles. Ten years ago in this journal I wrote that ‘many of the conundrums which perplexed diabetes specialists in the early 1950s have now been resolved.’ (Tattersall R. The dark ages of diabetes)1 Those who take a Whiggish view of history may imagine that once a pioneer shows the ‘right’ way to treat a condition, everyone would immediately follow suit, even without the benefit of NICE guidance. The story of how we reached the modern treatment of diabetes in pregnancy and that of ketoacidosis shows just how wrong this is.

Type 2 diabetes: the evolution of a disease
Authors: Lebovitz Harold E 
Published: January 2013

The heterogeneous nature of type 2 diabetes has become increasingly evident over the last 60 years, and particularly so in the last decade with the increased use of genetic fingerprinting techniques and understanding of environmental influences on the genome. The last decade has seen the expansion of the pharmacological options for the treatment of type 2 diabetes and the burgeoning of large randomized controlled trials. Whilst these trials have been designed to address important issues, many have generated more conundrums, highlighting the need for a diversity of approaches to investigate the pathophysiology of type 2 diabetes and its treatment.

Sixty years of diabetes management in primary care
Authors: Kirby Mike G 
Published: January 2013

The incidence of diabetes has increased exponentially over the last 60 years, meaning that the management of diabetes solely by specialist healthcare professionals is no longer feasible. Since the 1970s, primary and community healthcare professionals have increasingly treated patients with diabetes. Advances in diabetes equipment and new treatments have further enabled patients to be treated more conveniently in the community and this has enhanced their quality of life. There has also been an evolution in health service strategies for diabetes – notably growing acknowledgement of the benefits of intensive glycaemic treatment for patients with type 2, as well as type 1 diabetes, and the now well-recognised importance of effective shared care programmes between primary and secondary healthcare professionals. Thus, the organisation and delivery of care for patients with diabetes has improved dramatically since 1952. This article is a modified and updated version of ‘Review: Fifty years of diabetes management in primary care’ by Mike Kirby, published in, Br J Diabetes Vasc Dis 2002;2: 457-461.

Abstract

Background
The spread of MRSA strains at hospitals as well as in the community are of great concern worldwide. We characterized the MRSA clones isolated at Tunisian hospitals and in the community by comparing them to those isolated in other countries.

Results
We characterized 69 MRSA strains isolated from two Tunisian university hospitals between the years 2004-2008. Twenty-two of 28 (79%) community-associated MRSA (CA-MRSA) strains and 21 of 41 (51%) healthcare-associated MRSA (HA-MRSA) strains were PVL-positive. The PVL-positive strains belonged to predicted founder group (FG) 80 in MLST and carried either type IVc SCCmec or nontypeable SCCmec that harbours the class B mec gene complex. In contrast, very diverse clones were identified in PVL-negative strains: three FGs (5, 15, and 22) for HA-MRSA strains and four FGs (5, 15, 45, and 80) for CA-MRSA strains; and these strains carried the SCCmec element of either type I, III, IVc or was nontypeable. The nucleotide sequencing of phi7401PVL lysogenized in a CA-MRSA strain JCSC7401, revealed that the phage was highly homologous to phiSA2mw, with nucleotide identities of more than 95%. Furthermore, all PVL positive strains were found to carry the same PVL phage, since these strains were positive in two PCR studies, identifying gene linkage between lukS and mtp (major tail protein) and the lysogeny region, both of which are in common with phi7401PVL and phiSa2mw.

Conclusions
Our experiments suggest that FG80 S. aureus strains have changed to be more virulent by acquiring phi7401PVL, and to be resistant to β-lactams by acquiring SCCmec elements. These novel clones might have disseminated in the Tunisian community as well as at the Tunisian hospitals by taking over existing MRSA clones.
