Edgar Hynes Thompson: a collection of centenary reminiscences
Authors: Atkinson K. B. 
Published: March 2010

Abstract The idea for this collection of memories of E. H. Thompson began as a suggestion to potential contributors for anything from “a couple of sentences to a couple of paragraphs”. Both their willingness to write and the length of some contributions show how influential Thompson has been in the lives of so many of his colleagues and students. Contributors include two past‐presidents of the International Society for Photogrammetry and Remote Sensing and six past‐presidents of the Photogrammetric Society. Three longer essays are published as separate contributions to this feature.
Edgar Hynes Thompson: aerial triangulation and ISP Commission III
Authors: Proctor D. W. 
Published: March 2010

AbstractThis author worked with E. H. Thompson in several different contexts in the course of his military and civilian career, notably in developing Thompson’s ideas about analytical aerial triangulation into a production system at the Ordnance Survey and later as a lecturer under Thompson at University College London and as Secretary of ISP Commission III when Thompson was Commission President. This essay thus stands as a separate contribution from a close colleague.
Prevalence, incidence, and residual risk of major blood‐borne infections among apheresis collections to the American Red Cross Blood Services, 2004 through 2008

Published: March 2010

BACKGROUND: The number of apheresis collections increased significantly in recent years; however, data on viral marker rates among these collections are lacking.STUDY DESIGN AND METHODS: Apheresis collection data for 2004 to 2008 were analyzed. All collections were tested for antibodies and viral RNA for human immunodeficiency virus (HIV) and hepatitis C virus (HCV), hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti‐HBc), antibody to human T‐lymphotropic virus (anti‐HTLV), and other markers. HBsAg‐confirmed‐positive but anti‐HBc–nonreactive units were further verified by HBV DNA testing.RESULTS: From 2004 to 2008, apheresis collections for double red blood cells (R2) increased by 294% to a total of 37% of all apheresis collections. Marker rates (/100,000) among all apheresis collections were 1.41, 7.83, 2.04, and 0.28, for HIV, HCV, HBsAg, and HTLV. Among R2 collections, rates (/100,000) were 6‐ to 13‐fold higher than among non‐R2 collections for HIV (3.50 vs. 0.53), HCV (21.84 vs. 1.96), and HBsAg (5.83 vs. 0.44), but not HTLV (0.53 vs. 018). First‐time male R2 donors accounted for 25% to 100% of positivity but only 1% to 5% of the total number of apheresis collections. Incidence (/100,000 person‐years) and residual risk estimates among repeat apheresis donors between 2007 and 2008 for HIV were 3.82 and 1:1.0 million, for HCV were 1.53 and 1:3.2 million, and for HBsAg were 4.85 and 1:200,000. These estimates were comparable to those among repeat whole blood donors.CONCLUSION: The risk of major blood‐borne infections among current apheresis collections was low; however, an upward trend in the viral marker frequency among apheresis donations was attributable to the contribution of first‐time, male R2 donors.
Prevalence, incidence, and residual risk of human immunodeficiency virus and hepatitis C virus infections among United States blood donors since the introduction of nucleic acid testing

Published: March 2010

BACKGROUND: Nucleic acid testing (NAT) for human immunodeficiency virus (HIV) and hepatitis C virus (HCV) was introduced for blood donation screening in the United States in 1999. This study analyzes temporal trends of these two infections since NAT introduction.STUDY DESIGN AND METHODS: Donation data from 1999 to 2008 were analyzed; each donation was tested for antibodies and viral RNA for HIV and HCV. Incidence for first‐time (FT) donors was derived by multiplying that among repeat (RP) donors by the ratio of NAT yield rates between FT and RP donors. Incidence for all donors was the weighted mean based on percentage of FT and RP donors. Residual risk (RR) was determined using the window‐period model.RESULTS: During the 10‐year period approximately 66 million donations were screened with 32 HIV (1:2 million) and 244 HCV (1:270,000) NAT yield donations identified. HCV prevalence among FT donors decreased by 53% for 2008 compared to 1999. HIV and HCV incidence among RP donors increased in 2007 through 2008 compared to 2005 through 2006. During 2007 through 2008, HIV incidence was 3.1 per 105 person‐years (py), with an RR estimate of 0.68 per 106 (1:1,467,000) donations; HCV incidence was 5.1 per 105 py, with an RR estimate of 0.87 per 106 (1:1,149,000). The increase in HIV incidence was primarily among 16‐ to 19‐year‐old, male African American donors and that in HCV was primarily among Caucasian donors of 50 or more years. Donors from the Southern United States had higher incidence rates.CONCLUSION: HCV prevalence decreased significantly since NAT introduction. The increase in HIV and HCV incidence in 2007 through 2008 warrants continued monitoring and investigation.
A comparison of two robotic platforms to screen plateletpheresis donors for HLA antibodies as part of a transfusion‐related acute lung injury mitigation strategy
Authors: Vassallo Ralph R. , Hsu Susan , Einarson Mindy , Barone Jonathan , Brodsky Jaye , Moroff Gary 
Published: March 2010

BACKGROUND: Efforts to minimize white blood cell alloantibodies, responsible for transfusion‐related acute lung injury (TRALI) in components with high‐volume single‐donor plasma include consideration of plateletpheresis donor screening for human leukocyte antigen (HLA) antibodies. High‐throughput screening platforms make this feasible for large blood centers. Which platform to use, donor subgroups to screen, characteristics of detected antibodies, and operational impact of deferring reactive donors are important questions.STUDY DESIGN AND METHODS: We screened 2462 plateletpheresis donor sera for HLA antibodies on automated instruments using HLA Class I and II enzyme‐linked immunosorbent assays (ELISA) or a mixed Class I/II Luminex flow analyzer. Screen‐reactive samples were further tested by manual Luminex single‐antigen assay to determine antibody specificity, estimated corresponding antigen frequency, and signal strength.RESULTS: Alloexposed females had the highest reactivity rate on both platforms (21.0%), with much lower rates for nonexposed individuals or transfused males (1.4%‐5.4%). Increasing parity and more recent pregnancy increased their likelihood of screen reactivity. Deferring screen‐reactive parous females would result in at least a 4.8% plateletpheresis donor base decrement. Supplemental testing showed higher rates of nonspecific or natural antibodies in ELISA screen‐reactive alloexposed females (2.5%) than Luminex (0%). Both assays were more likely to identify antibodies directed against a larger number of HLA antigens and/or of presumed higher titer in alloexposed donors.CONCLUSION: A strategy screening only parous female donors is reasonable. Both automated HLA antibody detection platforms are easy to use and preferentially identify alloexposed individuals with antibodies of presumed higher titer directed against more recipient HLA antigens.

Authors: FERNÁNDEZ‐GUERRERO JUAN CARLOS , HERRADOR‐FUENTES JUAN , SÁNCHEZ‐GILA JOAQUIN , GUZMÁN‐HERRERA MANUEL , LOZANO CRISTÓBAL 
Published: March 2010

Background:
The zotarolimus‐eluting stent (ZES) has been documented as significantly reducing restenosis and target lesion revascularization (TLR) requirement compared to bare metal stents (BMS).
Methods:
In this single‐centered, prospective study we sought to evaluate the short‐ and medium‐term outcomes of ZES placement in bifurcated coronary artery lesions. Between August 2006 and December 2007, 107 consecutive patients (110 bifurcations) were recruited to have ZES placement in the lesion. The provisional T stenting (PTS) technique was used in 96.3%. Angiographic success was 100% in main vessel (MV) cases and 97.2% in that of side branch (SB).
Results:
With a mean follow‐up of 12.4 ± 1.77 (mean ± SD) months there were four deaths, three from cardiac cause (2.85%). There were 18 patients (19 bifurcations) requiring TLR (17.59%) for clinical reasons. The only predictor of TLR was the use diameter of ZES ≤3 mm.
Conclusion:
ZES can be used for bifurcation lesions using the PTS technique with a high rate of intraprocedural success; however, frequency of TLR is high, especially for stents with a diameter ≤3 mm. (J Interven Cardiol 2010;23:188‐194)
Los salarios bajos en cinco países europeos y en los Estados Unidos
Authors: BOSCH Gerhard 
Published: March 2010

Resumen.Fundándose en varias investigaciones Ilevadas a cabo en Alemania, Dinamarca, Estados Unidos, Francia, Países Bajos y Reino Unido, el autor demuestra que la proporción de empleos con salarios bajos y las condiciones laborales de los mismos vienen determinadas por las estructuras institucionales de cada país: el salario mínimo, las políticas laborales, los sistemas tributario y de seguridad social y la negociación colectiva. La relación inversa entre el nivel de remuneraciones y el de empleo no es inevitable: unas políticas activas de potenciación del trabajador y unas instituciones que fijen «limitaciones positivas» pueden impedir que la mejora de las condiciones laborales en la franja inferior de la escala salarial, aparte de reducir la desigualdad, se traduzca en un aumento del desempleo.
En la frontera entre mercado y «flexiseguridad». El trabajo en los hoteles de Dinamarca
Authors: ERIKSSON Tor , LI Jingkun 
Published: March 2010

Resumen.Aunque la limpieza de habitaciones es un trabajo sin cualificación, está relativamente bien pagado en Dinamarca debido a que el abanico general de salarios es bastante reducido. Los autores estudian las condiciones de trabajo en los hoteles y las medidas que toman los empresarios frente al auge de la competencia y la reestructuración. Es la hora de la reorganización de tareas, la intensificación del trabajo, la «externización» y la «flexiseguridad» al estilo danés. La ordenación flexible del trabajo, la estabilidad del empleo y las prestaciones sociales en especie contrarrestan las lagunas del seguro de desempleo y unas perspectivas de carrera escasas.
El modelo francés de la industria de la alimentación. Salarios relativos altos y trabajo intenso
Authors: CAROLI Ève , GAUTIÉ Jérôme , LAMANTHE Annie 
Published: March 2010

Resumen.Las industrias cárnica y pastelera de Francia proporcionan empleos poco cualificados con salarios y condiciones de trabajo mediocres. Pero la situación es más compleja y positiva de lo que cabía esperar gracias a dos elementos del «modelo fran‐cés»: el salario mínimo nacional y la ampliación de la eficacia de los salarios pactados en convenio colectivo a todos los trabajadores del sector. Con todo, las presiones para que se rebajen los costos laborales obligan a las empresas a proseguir la automatización y a ser más productivas y flexibles. Las cadenas minoristas también están tratan‐do de bajar los precios y de imponer la producción «justo a tiempo».
Ten‐year results of a three‐arm prospective cohort study on implants in periodontally compromised patients. Part 1: implant loss and radiographic bone loss
Authors: Roccuzzo Mario , De Angelis Nicola , Bonino Luca , Aglietta Marco 
Published: March 2010

AbstractObjectives: The aim of this study was to compare the long‐term outcomes of implants placed in patients treated for periodontitis periodontally compromised patients (PCP) and in periodontally healthy patients (PHP) in relation to adhesion to supportive periodontal therapy (SPT).Material and methods: One hundred and twelve partially edentulous patients were consecutively enrolled in private specialist practice and divided into three groups according to their initial periodontal condition: PHP, moderate PCP and severe PCP. Perio and implant treatment was carried out as needed. Solid screws (S), hollow screws (HS) and hollow cylinders (HC) were installed to support fixed prostheses, after successful completion of initial periodontal therapy (full‐mouth plaque score <25% and full‐mouth bleeding score <25%). At the end of treatment, patients were asked to follow an individualized SPT program. At 10 years, clinical measures and radiographic bone changes were recorded by two calibrated operators, blinded to the initial patient classification.Results: Eleven patients were lost to follow‐up. During the period of observation, 18 implants were removed because of biological complications. The implant survival rate was 96.6%, 92.8% and 90% for all implants and 98%, 94.2% and 90% for S‐implants only, respectively, for PHP, moderate PCP and severe PCP. The mean bone loss was 0.75 (± 0.88) mm in PHP, 1.14 (± 1.11) mm in moderate PCP and 0.98 (± 1.22) mm in severe PCP, without any statistically significant difference. The percentage of sites, with bone loss ≥3 mm, was, respectively, 4.7% for PHP, 11.2% for moderate PCP and 15.1% for severe PCP, with a statistically significant difference between PHP and severe PCP (P<0.05). Lack of adhesion to SPT was correlated with a higher incidence of bone loss and implant loss.Conclusion: Patients with a history of periodontitis presented a lower survival rate and a statistically significantly higher number of sites with peri‐implant bone loss. Furtheremore, PCP, who did not completely adhere to the SPT, were found to present a higher implant failure rate. This underlines the value of the SPT in enhancing the long‐term outcomes of implant therapy, particularly in subjects affected by periodontitis, in order to control reinfection and limit biological complications.

Collagen barrier membranes decrease osteoclastogenesis in murine bone marrow cultures
Authors: Agis Hermann , Magdalenko Magdalena , Stögerer Katharina , Watzek Georg , Gruber Reinhard 
Published: March 2010

AbstractObjective: Collagen barrier membranes (CBM) are used for guided bone regeneration to support the process of graft consolidation. It remains, unknown however, whether CBM can affect the consolidation of bone grafts by controlling the differentiation of progenitor cells into bone‐resorbing osteoclasts and bone‐forming osteoblasts.Material and Methods: To gain an insight into the underlying mechanisms, we performed in vitro bone marrow cultures on CBM (Bio‐Gide®) under conditions that favor osteoclastogenesis and osteoblastogenesis, respectively. Measures of osteoclastogenesis were based on the number of tartrate‐resistant acid‐phosphatase‐positive (TRAP+) multinucleated cells. Resorption assays revealed the activity of mature osteoclasts. Osteoblastogenesis was determined by alkaline‐phosphatase activity. Viability was investigated utilizing the MTT assay.Results: Cultivation of murine bone marrow on CBM reduced the number of TRAP+ multinucleated cells compared with cultures on tissue culture plates. Inhibition of osteoclastogenesis was observed on the porous and the dense CBM surfaces. The majority of TRAP+ cells were mononucleated and the decreased osteoclastogenesis was not due to changes in cell viability. Furthermore, CBM are inert regarding the resorptive activity of mature osteoclasts. Moreover, osteoblastogenesis was not reduced when bone marrow cells were grown on the surface of CBM.Conclusions: These in vitro findings demonstrate that CBM can reduce the formation but not the activity of multinucleated osteoclasts. Our data further reveal that the formation of osteogenic cells from their progenitors is not reduced by the CBM. Overall, our results suggest that the beneficial effects of CBM during graft consolidation may involve their direct impact on osteoclastogenesis. To cite this article:

Periodontal health in Europe: future trends based on treatment needs and the provision of periodontal services – position paper 1
Authors: König J. , Holtfreter B. , Kocher T. 
Published: March 2010

AbstractThis review gives an update on recent epidemiologic data on periodontal diseases and a description of current periodontal services in Europe. A Medline search of articles published within the last decade with the keywords epidemiology, prevalence, periodontitis, tooth loss, and Europe was performed. Data on provision of dental services originated from international databases. Epidemiologic data on the prevalence of edentulism, the number of missing teeth, the prevalence of probing depth (Community Periodontal Index – CPI ≥ 3 or Pocket Depth – PD ≥ 4 mm), and clinical attachment loss (CAL ≥ 4 mm) displayed a fragmentary picture within Europe. With respect to the limited data on periodontal health, Spain, Sweden, and Switzerland ranked as the healthiest among European countries in contrast to Germany where increased tooth loss and the highest prevalence of CAL ≥ 4 mm were reported. The role of dental auxiliaries especially of dental hygienists and/or the medico‐legal framework in which they work, appears to be an important factor in provision of effective periodontal care. Actual epidemiologic data on periodontal diseases are non‐homogeneous and absent from several European countries. This emphasises the need for more national representative epidemiological studies with a uniform design to permit comparability between different nations. Merging actual epidemiologic data with former data on provision of periodontal care may help to explain differences in periodontal parameters on a population basis and to define future provision of dental care.

Johnston P, Bergeron NE. Variation of juvenile Atlantic salmon (Salmo salar) body composition along sedimentary links.  Ecology of Freshwater Fish 2010: 19: 187–196. © 2010 John Wiley & Sons A/SAbstract –  The objective of this study was to determine the proximate body composition of juvenile Atlantic salmon along the sequence of aquatic habitat types created by longitudinal changes in the riverbed substrate of two rivers (i.e., sedimentary links units). Interesting trends in the body composition were observed but our initial hypothesis, that fish of the upstream sections have higher energy content, was nevertheless not verified. No common longitudinal pattern was detected in the body composition (water, lipid, energy density) along the studied rivers. Trends in the body constituents were different between age‐classes and rivers, whereas they were highly variable within‐ and among‐samples. There was however a common trend in the pattern of variations, with the coefficient of variations increasing in the downstream direction for almost all constituents, age‐classes and rivers. Potential abiotic and biotic factors that might have contributed to these observations are discussed.

AbstractQuestion: Does transplantation of small blocks of turfs contribute to restoration of species‐rich meadows on fallow land? What is the role of vegetative spread and seedling establishment of meadow plants in the neighbourhood of the transplanted turfs?Location: Bílé Karpaty Mountains, SE Czech Republic.Methods: Twenty‐five meadow blocks, 0.4 m × 0.4 m in size, were transplanted to fallow land (unfertile and dry) and species composition was monitored in the source area, in the transferred turfs and in their neighbourhood for 3 yr. Multivariate analyses were used to assess successional trends.Results: The transferred meadow blocks served as a source of diaspores for the seed‐limited fallow land. Out of 80 transplanted species 17 species spread to adjacent plots within 3 yr. The frequency of plants expanding from the transferred turfs, either vegetatively or by seeds, was relatively low and from 2002 to 2004 a total of 22 species declined in the transferred turfs before expanding to the neighbourhood. Successional trends in species composition of the plots adjacent to the transferred blocks were strongly significant compared with the vegetation of the source area despite the short‐term data used for the evaluation. The role of the seed bank in restoration was negligible.Conclusions: In infertile and dry environments, transplanted turfs may significantly speed up restoration, especially if natural sources of target plant seeds are not available in the neighbourhood. However, the restoration process is long‐term and not all transferred plants can be expected to establish in the fallow land.

Published: March 2010

ABSTRACTBackground: The Neoss implant system has been available since 2004. Few studies documenting the clinical performance of this implant are available.Purpose: To study the stability and clinical/radiographic outcomes of Neoss implants 1 year of loading when using a two‐stage protocol.Materials and Methods: Ninety (90) consecutive patients scheduled for implant treatment using a two‐stage procedure were enrolled in a prospective follow‐up study. A total of 218 implants (Neoss System, Bimodal surface, Neoss Ltd, Harrogate, UK) in diameters of 3.5, 4.0, and 4.5 mm and in lengths from 7 to 15 mm were placed to support 29 single tooth replacements, 53 partial bridges, 5 full bridges, and 10 overdentures in both jaws. Abutment connection was made after a healing period of 3–4 months. The patients were followed during 1 year of loading with clinical, radiographic, and resonance frequency analysis (Osstell Mentor™, Osstell AB, Gothenburg, Sweden) examinations. Prostheses were removed at the annual check‐up for individual testing of implant stability.Results: Three implant failures were experienced, giving a survival rate of 98.6% after 1 year. A mean bone loss of 0.6 mm (SD 0.8) was observed after 1 year. There was a significant inverse correlation between implant diameter and marginal bone loss (p < .003). The mean implant stability quotient levels were 73.7 (SD 7.6), 74.4 (SD 6.4), and 76.7 (SD 5.2) at placement, abutment connection, and first annual check‐up, respectively. The stability had increased significantly from placement to 1 year (p < .001) and from abutment to 1 year (p < .0001). Implant stability was higher in the mandible than in the maxilla at all time points. There was a significant correlation between bone quality and stability at placement (p < .0001) and abutment connection (p < .001) but not after 1 year.Conclusions: The use of Neoss implants for prosthetic rehabilitation of consecutive edentate patients with different needs resulted in predictable clinical and radiographic outcomes after 1 year of loading. Implant stability measurements revealed a favorable bone tissue reaction to the implants.
