Abstract

Objectives
We aim to address several clinical interests regarding lung volume reduction surgery (LVRS) for severe emphysema using meta-analysis and systematic review of randomized controlled trials (RCTs).

Methods
Eight RCTs published from 1999 to 2010 were identified and synthesized to compare the efficacy and safety of LVRS vs conservative medical therapy. One RCT was obtained regarding comparison of median sternotomy (MS) and video-assisted thoracoscopic surgery (VATS). And three RCTs were available evaluating clinical efficacy of using bovine pericardium for buttressing, autologous fibrin sealant and BioGlue, respectively.

Results
Odds ratio (95%CI), expressed as the mortality of group A (the group underwent LVRS) versus group B (conservative medical therapies), was 5.16(2.84, 9.35) in 3 months, 3(0.94, 9.57) in 6 months, 1.05(0.82, 1.33) in 12 months, respectively. On the 3rd, 6th and 12th month, all lung function indices of group A were improved more significantly as compared with group B. PaO2 and PaCO2 on the 6th and 12th month showed the same trend. 6MWD of group A on the 6th month and 12th month were improved significantly than of group B, despite no difference on the 3rd month. Quality of life (QOL) of group A was better than of group B in 6 and 12 months. VATS is preferred to MS, due to the earlier recovery and lower cost. And autologous fibrin sealant and BioGlue seems to be the efficacious methods to reduce air leak following LVRS.

Conclusions
LVRS offers the more benefits regarding survival, lung function, gas exchange, exercise capacity and QOL, despite the higher mortality in initial three postoperative months. LVRS, with the optimization of surgical approach and material for reinforcement of the staple lines, should be recommended to patients suffering from severe heterogeneous emphysema.

Abstract
Health-related physical fitness has decreased with age; this is od immense concern to adolescents. School-based health intervention programs can be classified as either population-wide or high-risk approach. Although the population-wide and risk-based approaches adopt different healthcare angles, they all need to focus resources on risk evaluation. In this paper, we describe an exploratory application of cluster analysis and the tree model to collaborative evaluation of students’ health- related physical fitness from a high school sample in Taiwan (n=742). Cluster analysis show that physical fitness can be divided into relatively good, moderate and poor subgroups. There are significant differences in biochemical measurements among these three groups. For the tree model, we used 2004 school-year students as an experimental group and 2005 school-year students as a validation group. The results indicate that if sit-and-reach is shorter than 33 cm, BMI is >25.46 kg/m2, and 1600 m run/walk is >534 s, the predicted probability for the number of metabolic risk factors ≥2 is 100% and the population is 41, both results are the highest. From the risk-based healthcare viewpoint, the cluster analysis can sort out students’ physical fitness data in a short time and then narrow down the scope to recognize the subgroups. A classification tree model specifically shows the discrimination paths between the measurements of physical fitness for metabolic risk and would be helpful for self-management or proper healthcare education targeting different groups. Applying both methods to specific adolescents’ health issues could provide different angles in planning health promotion projects.
Estimating Dynamic Income Responses to Tax Reform
Authors: Holmlund Bertil , Söderström Martin 
Published: November 2011

Abstract
We study income responses to income tax changes by using a large panel of Swedish tax payers over the period 1991–2002. Changes in statutory tax rates as well as changes in tax bracket thresholds provide exogenous variations in tax rates that can be used to identify income responses. We estimate dynamic income models which allow us to distinguish between short-run and long-run effects in a straightforward fashion. For men, the estimates of the long-run elasticity of income with respect to the net-of-tax rate hover in a range between 0.10 and 0.30. The estimates for women are statistically insignificant. We simulate the fiscal consequences of a tax reform that reduces the top marginal tax rate by five percentage points. Such a reform may have negligible effects on tax revenues when the interactions between income taxes and other taxes are taken into account.

Abstract
Objective—To compare results for 3 commercially available microbiological media plates with those for standard bacteriologic testing of bovine milk.
Sample—Milk samples from postpartum cows and cows with a high somatic cell count (SCC) or clinical mastitis (CM).
Procedures—Sample-ready Staphylococcus culture medium (SRSC) plates were used to detect Staphylococcus aureus in milk samples obtained from postpartum cows and cows with a high SCC or CM. Rapid coliform count (RCC) plates were used to detect coliforms in milk samples obtained from cows with CM. Aerobic count (AC) plates were used to detect streptococci in CM samples. Fresh mastitic milk samples were frozen and then thawed to evaluate the effects of freezing for the SRSC and RCC plates. The effects of dilution (1:10) of samples were determined. Agreement of results between the commercially available plates and standard bacteriologic testing was evaluated.
Results—The ability of SRSC plates to detect S aureus in milk samples was highest with diluted samples from postpartum cows and cows with a high SCC or CM. Sensitivity of the RCC plate for detection of coliforms was highest with diluted mastitic milk samples. The AC plates had a poor positive predictive value for detection of streptococci in mastitic milk samples. Freezing increased S aureus detection.
Conclusions and Clinical Relevance—Overall, the SRSC and RCC plates were accurate, were easy to use, and yielded results comparable to those of standard bacteriologic testing for the detection of S aureus and coliforms in bovine milk.
Des familles entre France et Portugal
Authors: Charbit Yves , Petit Véronique 
Published: November 2011

This paper examines the consequences of geographical mobility on family structures and nuptiality, and more specifically on endogamy, through a comparison of heads of households who migrated and of those who never left their native village. Slight differences are observed, but for those who migrated, neither the traditional model of family nor nuptiality are influenced by migration.
For the second generation, things are more complex. Children of migrants spending their holidays in the village are different from those born to migrants who definitively returned to Portugal, who in turn tend to be close to those born to non migrants. As shown by data on education, citizenship, place of residence, children living abroad seem to wish to integrate into the host country, but this does not imply a rejection of their country of origin, as proved by the frequency of visits to the villages.

Published: November 2011

Purpose To investigate the clinical and electrophysiologic effect of a single intravitreal injection of bevacizumab for neovascular glaucoma (NVG) after ischemic central retinal vein occlusion (iCRVO). Methods Nineteen eyes from 19 patients with NVG secondary to iCRVO were randomly allocated to either an intravitreal bevacizumab injection and panretinal photocoagulation (PRP) (10 eyes) or PRP alone (9 eyes). The primary outcome measure was the change in the total retinal function 6 months after treatment, demonstrated by full-field electroretinography (ERG). Secondary outcomes included visual acuity, intraocular pressure (IOP), glaucoma medication, additional IOP-lowering treatment, and the presence of ocular neovascularization before treatment, and 1 week, 2 months, and 6 months after treatment. Results The regression of ocular neovascularization in the bevacizumab/PRP group was confirmed 1 week after injection. Patients in both study groups had very poor visual acuity at baseline. This remained unchanged. There was no significant difference in the mean IOP between the groups at any point in time. The a-wave amplitudes of combined rod-cone response were significantly decreased after 6 months in the bevacizumab/PRP group (p=0.028), compared with the baseline values. The a- and b-wave amplitudes of combined rod-cone response and the b-wave amplitudes of the 30-Hz flicker response were also markedly reduced compared with the PRP group (–60%, −43%, −47% vs +23%, −36%, −16%, respectively). Conclusions This study suggests that intravitreal injection of bevacizumab is valuable in the treatment of NVG by hastening the resolution of neovascularization, while the full-field ERG results indicate that bevacizumab may reduce the photoreceptor function in NVG patients.

Malpositioning of the acetabular component in total hip arthroplasty (THA) increases the risk of dislocation, reduces the range of motion and may contribute to bearing surface wear. During computer assisted navigation, the anterior pelvic plane is registered intraoperatively by percutaneous palpation, but this may be unreliable. The aim of our study was to evaluate the reliability of imageless navigation in acetabular positioning employing data acquisition in the supine position and surgery in the lateral position (‘flip technique’). We report 24 patients affected by primary osteoarthritis undergoing THA in which implants were placed with a conventional free-hand technique using the acetabular transverse ligament for cup orientation. For imageless navigation we used Orthopilot-Aesculap software. All patients had a postoperative computed tomography (CT) scan at three months, using previously validated dedicated software for cup orientation. Data collected using navigation software were compared with CT measurements. The mean acetabular inclination and anteversion recorded intra-operatively using navigation software were respectively 41°5’ (SD: 9.61) and 9°5’ (SD: 4.01) respectively. The mean inclination and anteversion calculated post-operatively by the CT based image software were 44°2’ (SD 5.83) and 14°4’ (SD 6.42) respectively. There was a statistically significant difference between the anteversion values (p=0.04). Therefore, the acquisition of parameters in the supine position with surgery performed in the lateral decubitus position creates unreliable data concerning cup anteversion using an imageless navigation system, and therefore the ‘flip technique’ cannot be recommended.
A QoS‐based fine‐grained reputation system in the grid environment

Published: November 2011

SUMMARYThe accuracy of feedback presentation, the sensitivity, and the robustness of reputation evaluation are critical issues to be addressed in a reputation system under the grid environment. This paper proposes a QoS‐based fine‐grained grid reputation system, where economic elements are considered to make the reputation system more sensitive in the commercial grid environments. A novel fine‐grained feedback presentation model based on aggregation of objective QoS attributes and subjective opinions of evaluators is proposed to enable a semi‐automatic, personalized and accurate feedback presentation. Through the introduction of a punishment factor and the adaptive reference of a previous trust value, the proposed reputation system effectively improves the sensitivity of the reputation evaluation. Moreover, the weighted combination of interorganizational trust, direct trust and recommended trust makes the reputation system more robust against collusion attacks. Simulation results show that the proposed reputation system can practically predict feedback and effectively resist malicious attacks such as fake transaction attacks and badmouthing attacks. This provides a clear advantage in the applications of grid service selection. Copyright © 2011 John Wiley & Sons, Ltd.
Enhanced MC3T3 preosteoblast viability and adhesion on polyelectrolyte multilayer films composed of glycol‐modified chitosan and hyaluronic acid
Authors: Holmes Christina A. , Tabrizian Maryam 
Published: November 2011

AbstractLayer‐by‐layer polyelectrolyte films made of the naturally derived polysaccharides chitosan (CHI) and hyaluronic acid (HA) constitute a well‐studied system for the development of cell‐responsive biointerfaces. However, many cell lines exhibit decreased adhesion to CHI/HA multilayer films, particularly as the number of bilayers is increased. Here, our group demonstrates that films composed of glycol‐modified chitosan exhibit significantly improved MC3T3 preosteoblast adhesion and viability compared to corresponding films consisting of unmodified CHI. These differences in cellular adhesion are likely due to differences in surface topography and roughness, as measured via atomic force microscopy (AFM), as well as in film chemistry and the water solubility of the cation, since both types of films exhibited similar: thickness, as measured via quartz crystal microbalance and AFM; wettability, as measured via contact angle; and serum protein adsorption, as measured via the bicinchoninic acid assay. © 2011 Wiley Periodicals, Inc.

AbstractWe report on the electrical properties of AlInN/GaInN heterostructures fabricated with InN molar fractions of 0 to 0.6 in the GaInN layer. High‐density two‐dimensional electron gases are formed near the interfaces of AlInN/AlN/GaInN at InN molar fractions of 0.3 and 0.6. The Al0.82In0.18N/AlN/Ga0.4In0.6N/GaN heterostructure field‐effect transistors exhibited static characteristics. The maximum drain‐source current reached a value of 0.26 A/mm (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The Hoard from West Buckland, Somerset
Authors: Taylor Robin J. 
Published: November 2011

SummaryThe small Middle Bronze Age hoard from West Buckland, Somerset has been assumed to be lost since its publication in 1880. Plaster casts still exist of the objects in the Pitt Rivers Museum, Oxford. Parallels are given for these objects and their chronology discussed. The way in which the casts may have reached the collection is considered. The circumstances of the find are also discussed, with the possibility that these objects may be from a burial, thus raising the question of our definition of hoards.
St. Mary at Wiveton in Norfolk, and a Group of Churches Attributed to its Mason
Authors: Fawcett Richard 
Published: November 2011

SummaryA number of ecclesiastical buildings in Norfolk and northern Suffolk show a common repertoire of distinctively elaborated mouldings, which in several cases involves such precise repetition of formations that the same templates must have been used repeatedly. On the evidence of the mouldings, and of other detailed similarities between the buildings, it is argued that they may all be seen as the work of the same designing mason, and the documentation suggests that his active career was centred on the second quarter of the fifteenth century. The range of his personal manner of design in parochial churches is best seen at Wiveton, near the north coast, but he was also able to work on a more expanded scale, as in the Erpingham Gate into Norwich Cathedral close; the connecting link between the two scales of his work is to be found in the parochial west tower of Wymondham abbey.
Welsh Bucklers
Authors: Edwards Ifor , Blair Claude 
Published: November 2011

SummaryThe paper deals with a well-known group of Tudor bucklers (once thought to be Roman), made of leather reinforced with riveted iron or brass rings, sometimes accompanied by radiating strips. The evidence of a group of fifteenth-and sixteenth-century Welsh poems and other records is used to establish that they originated in Wales, and that Wrexham was a noted centre of production. A corpus of recorded examples is given.
The Cross in Medieval Heraldry
Authors: Brault Gerard J. 
Published: November 2011

The multiplicity of terms used to blazon crosses and the diversity of manners in which they were depicted constitute one of the most confusing aspects of medieval heraldry. Sir William St. John Hope deplored this situation in the following terms:As regards the cross, heraldic writers have gone mad, and from the few simple crosses of pre-Tudor days there have been evolved scores of fantastic forms for which it would be difficult to find instances outside the heraldry books. In the Glossary of Heraldry, published in 1847, upwards of fifty varieties are enumerated, and there are other modern works in which they exceed two hundred!

‘What's not devoured by Time's devouring hand?Where's Troy, and where's the Maypole in the Strand?’That couplet is not, I need scarcely tell you, a contemporary one; it was written by the Reverend James Bramston in the eighteenth century. However, in the predicament now facing our heritage the title of the work might well suggest contemporaneity: it is The Art of Politics. And in the present climate of cuts, economies and withdrawal of grants to worthy causes, I might add my own doggerel:There's every indication that the StateResorting in extremity to Fate,Whose way it is to ravage and destroy,Would Schedule scarce a hectare of TroyOr, even less, would lend a ready handTo Designate the Maypole in the Strand.
The Risley Park Silver Lanx: A Lost Antiquity from Roman Britain
Authors: Johns Catherine 
Published: November 2011

SummaryIn 1729, a decorated fourth-century Roman silver dish bearing a Christian inscription was found at Risley Park, Derbyshire. Damaged when found, the fragments of the vessel were soon lost, but an illustrated account of it was published by William Stukeley in 1736. Stukeley and later authorities interpreted the inscription as implying that the dish had belonged to a late Roman church in France, and considered that it had been brought to Britain as loot in the Middle Ages. This paper presents a description and assessment of the Risley Park lanx in the light of the greater knowledge of late Roman silver plate now available, and makes the suggestion that the vessel may have been imported into Britain in the Roman period.
Excavations at Lincoln. Third Interim Report: Sites outside the Walled City 1972–1977

Published: November 2011

SummaryExcavations outside the walled area (of the ancient city) have added much to our knowledge of Lincoln's historical development and have demonstrated the potential of the suburbs for further problem-orientated investigations. Evidence was recovered in 1972 for a late Iron Age settlement on the east bank of the Brayford to the south of the later Roman city. The Ermine Street frontage here was heavily built up from the mid-second century for a distance of at least 400 m. from the south gate of the extended colonia. Only slight traces of Roman occupation, however, have been recovered outside the east and west walls of the lower town. Investigation of the medieval suburb of Butwerk revealed a sequence of domestic structures from its originc. A.D. 1000 through to the post-medieval period, while the development of the ecclesiastical site of St. Mark's church in Wigford reflected to a large extent the changing fortunes of this important southern suburb. Limited work on the north and east banks of Brayford Pool exposed remains of early medieval waterfronts, but the exploitation of the city's waterside is as yet little understood. Further progress has been made in understanding the structures connected with the water supply to the Roman city, and an interesting Roman tile kiln 10 km. south-east of the city is also described.
The Earlier Prehistoric Settlement of Cranborne Chase-the First Results of Current Fieldwork
Authors: Barrett John , Bradley Richard , Green Martin , Lewis Barry 
Published: November 2011

SummaryThis paper offers a provisional assessment of the development of settlement in part of Cranborne Chase between the Mesolithic and the Late Bronze Age. It builds upon the results of Pitt Rivers' work in this region between 1880 and 1900, as well as more recent excavation and field survey. Special emphasis is placed on three factors: the relationship between activity in this area and settlement both in central Wessex and on the coastal plain; the place of the more prominent ‘public’ monuments in contemporary patterns of settlement and exchange; and the relationship between cemeteries and contemporary living sites. We present the first results from the extensive excavation of two Deverel-Rimbury enclosures and associated barrows, and a new analysis of Pitt Rivers' work on the urnfield at Handley Barrow 24.

Published: November 2011

SummaryThe Department of Urban Archaeology, City of London, was set up in December 1973 as part of Guildhall Museum, now the Museum of London. Since then it has excavated sixteen sites and carried out numerous watching briefs. Most of the formal excavations have been conducted on the vital waterfront sites, made available for the first time, and on the Roman and medieval defences of the City. Important evidence of the elusive Saxon occupation is gradually coming to light, and the work is accompanied by specialist research, particularly finds, environmental and documentary.
